    In mining industry, milling machinery plays an important role and there are various kinds to meet different working environment, such as 3R or 4R Raymond mill, ball mill, micro-powder grinder, roll mill, rod mill and so on. Starting milling, should check whether all the maintenance doors closed tight, check the crusher jaw plate gap is in line with the feed grain size, adjust the analytical engine speed should reach approximate finished size requirements. And press to start the order.

    1. starting basket bucket elevator;

    2. activate the jaw crusher;

    3. when there are material silo, start analysis machines;

    4. to start the air blower (air load to start until the normal operation after the load);

    5. start the host, start the host instant starts electromagnetic vibrating feeder.

    Grinding work shall be started at this time. Simple sequence of operations are as follows: Start: enhancing machine crusher → Fan → → analyzer mainframe → Feeder. Shutdown should be in the following order the closure of the machine:

    1. first close the feeder to feed material;

    2. about one minute after the cessation of host;

    3. blowing the net residual powder after the cessation of sub-blowers;

    4. the final closing analyzer.

    As to the tips for maintenance, there are some suggestions below:

    1. Milling machine using the process, there should be regular staff responsible for the custody of the operator must possess a certain level of technology, milling machines are installed before the operation is to conduct technical training for customs officers must make to understand the principle of mill performance, familiar with operational procedures.

    2. For the mill to work, there should be equipment 'Maintenance of the safe operation of systems' can ensure the long-term safe operation of mills at the same time have the necessary repair tools and accessories grease.

    3. Mill use for some time, maintenance should be carried out, while roller grinding ring Blade repair of wearing parts such as replacement roller device in use before and after the connecting bolt nut plug should be carefully examined whether there is loosening , lubricating oil is to add a little grease.

    4. Roller devices of the time more than 500 hours or so to replace the roller when the roller kit must be cleaned of all rolling bearings, damaged parts should be replaced, dispensing fuel or butter can be used to manually hand gun.

    Milling machine in the normal working hours are not allowed to refuel at random, to ensure safety in production and milling machine in any part of the unusual noise, or a sudden increase in load should immediately stop inspection, troubleshooting, so as to avoid a major accident.

    Raymond Mill mainly by the host, analyzers, blower, finished cyclone, cyclone powder and air tube. Among them, the host from the rack, inlet volute, blade, roller, grinding ring, cover composition.

    In the working process of Raymond mill, how is the winnowing process? After grinding the material, fans will be blown in the White case, the blowing powder, placed in the grinding chamber through the top of the analyzer for sorting, fine through coarse material into the grinding raymond mill chamber and re-grinding, compliant with the fineness airflow into the cyclone collector, collected and discharged through a powder outlet, is finished. Airflow from the top of a large cyclone collector tube back into the return air fan, air duct is circular, and in the flow under negative pressure, circulation air duct to increase air flow between the host partly by the exhaust fan and exhaust pipe into the small cyclone collector device, for purification.

    Correct operation is important for a machine, such as jaw crusher, cone crusher, impact crusher, ball mill, sand washer, belt conveyor, and the maintenance is also useful to extend the machine's life. Just taking Raymond mill as an example.

    1. Non-metal block into the machine, otherwise it will damage the grinding roller and grinding ring, and even center hanger.

    2. The feeding should be uniform, not suddenly much less ignored. Excessive feeding blocked duct will reduce the yield, easy to burn out the motor, feeding too little will affect production. Feed size: hard materials less than 15 mm in diameter, preferably, soft material for the 20 mm diameter, non-bulk material added to the machine.

    3. Air volume control: the intake pipe is located on the blower air volume control valve, generally open to the maximum position, according to fineness, yield requires an appropriate adjustment. Located on the exhaust pipe outlet exhaust valve, transferred into the feed opening can be no dust emitted. Air volume is small, thin high. It should be noted, the wind is too small, the host is easy duct below the sediment material, please adjust.

    4. Fine adjustment, based on the size of the material, hardness, moisture content, the proportion of different degree of processing are different thickness, can be adjusted at the top of the analyzer, high speed, fineness, low speed, low fineness. Improve the fineness, the output will be reduced accordingly, if it is mainly the fan speed when debugging, the user can flexibly.

    5. Ring roller raymond mill scrap the limit, the minimum remaining wall thickness of not less than 10mm.

    6. Stop, stop feeding, the system still continue to operate, continue to make residual abrasive grinding, about a minute, turn off the main motor and the motor analyzer, stop grinding work, and then stop the fan motor to blowing off the powder residue.

    What does the gold mining brings when we talk about business? It means profit. But what does gold mining brings when we talk about nature? It will mean disasterÂ… because doing the gold mining operations will turn the whole place into a desert without any trees to grow and without any animal to live. The gold mining operations will really change the natural resources of water shades and even lose the chances of safety living to those who lives at the low landareas of the gold mining operations. Especially the farmers who are usually been making the rivers as their source of water to take care of all their flocks and animals. Mining equipments (jaw crusher, impact crusher, ball mill) usually the gold mine operations will bring a great fight and arguments between the environmentalist and the side of the mining operators or mining company because all they up to is to take the gold without thinking the bad results that the mining could brings as long as they can get the gold deposits in that certain place. But no matter how the environmentalist will opposed the gold mining operations, it will only be heard for a while but it is always the gold mining operators who will win. Because what would be the possible opposition that the environmentalist will use to opposed about nature, the mining company can present their equipment that will serve as nature friendly according to their own evaluation. But if you will really try to look at the result of every mining operation it will only really damage the natural resources of the place because when the gold mine operations are done they will evacuate from the place and live it in a deserted life and nature. What they are going to live in that place is a totally damage place of the mountain that you will never see what it was before.

    Gold mining companies are fully equip with all the heavy equipment (Raymond mill, belt conveyor, cone crusher, hammer crusher) they need to continue the gold mining operations, to bring profit for the company but not to protect the nature and the people who are living after the place where the gold mining been doing its operations. Gold mining are using dynamites to brake the mountains. As a result floods will happen anytime and all the time. When the rainy days comes, floods will risk the whole place especially the low land areas where the waters are going to overflow and damaging the huge amounts of farmlands in the lowland areas that will even kill people who cannot manage themselves from the rushing flood of water coming from the high lands. And it is very sad to know that even if these things are happening over and over again wide range of mining operations are still going on with their operations until they are done and live the place to find another gold mine explorations.

    Crushing productivity is an important technical and economic indicators, the broken particle size is guaranteed under the premise of crusher manufacturers and users are required to maximize crusher productivity, thereby improving

    Crusher user economic benefits. Especially in recent years, as the global mineral depleted, but in expanding the scale of mining, crushing grinding through a sharp increase in ore processing, thereby increasing productivity is more important crusher. Therefore, the crushing machine productivity must be as multi-objective programming model is an important objective function. PE jaw crusher, VSI impact crusher, vertical mill are useful.

    Jaw crusher broken wall cavity shape is formed by rolling acetabular wall and work space. Cavity design is good or bad, on the economic and technical indicators crusher (productivity, energy consumption, broken particle size and grain shape and the broken wall and rolling wear of acetabular wall, etc.) have a significant impact. Therefore, the cavity-shaped performance as the jaw crusher to be multi-objective programming model is one important objective function. Quality based on a fixed principle, according to the broken machine performance parameters, can solve the ideal curve laminated crushing chamber shape, but because of the broken layer crushing chamber work states and crusher to the nip angle, the discharge opening and the crushing chamber height requirements and standards restrictions, the actual curve obtained laminated cavity-shaped crusher often only approximating the ideal curve-shaped laminated crushing chamber. Layer of the crushing chamber can be broken by the amount of material equivalent standard deviation as a measure of crusher cavity design of the pros and cons, so the crushing chamber through the broken layer equivalent material standard deviation as a measure of the amount of performance-shaped cavity of the objective function.

    Crushing machine crushing grinding product size is an important economic and technical performance indicators, broken particle size will have a direct impact on the economic benefits to the user crusher, the crusher performance reflects the pros and cons. Broken machine users, to meet the productivity requirements of the crusher premise, are expecting better quality of fragmentation products, thus crushing the product size distribution as a jaw crusher to be multi-objective programming model is an important objective function. In production practice, generally use less than the crusher closed side of the nesting population broken broken products, the total percentage of products that calibration marker size as a measure of quality of technical indicators broken.

    State-owned power utility Eskom’s current “worst-case scenario” for delivering initial power to the grid from the first Medupi power station unit, or Unit 6, was currently September 2013, Engineering News Online has learned.

    The unit would be the first of six to begin producing at the R100-billion (R125-billion when interest during construction was included), 4 800 MW coal-fired plant, which was currently under construction near Lephalale, in the Limpopo province.

    The scenario was premised on there being no material improvement in the delivery of the key boiler contract, which was being built and installed by Hitachi in association with local and international subcontractors. Together, the boilers for Medupi, as well as the Kusile power station, which is being built almost simultaneously in Mpumalanga, were valued at R38.5-billion and represent the largest single contract ever awarded by Eskom.

    There had been a range of problems with the project, which moved ahead in 2006 despite the absence of a finalised design and a funding plan, as well as a serious dearth of internal project management capacity, which was augmented by PB Power.

    Initial site preparation was delayed, which had a knock-on effect to the laying of the civil foundations by a joint venture led by Murray & Roberts (M&R). Progress has since been made in agreeing the precise scope of the works and additional advances had been paid to M&R in line with that new scope.

    But the boiler portion remained a concern and Eskom currently had serious doubts about the ability of Hitachi and its subcontractors to deliver on the contracted 48-month delivery schedule for the first unit. We manufacture complete sets of mining equipment, jaw crusher, compact crusher, ball mill.

    A source close to the development said that, in other parts of the world, Hitachi generally delivered such units in 62 months and that it was also currently about ten-and-a-half months behind on the Medupi delivery schedule.

    The delays had arisen partly as a result of serious deviations, against the original design, on the steel fabrication portion of the contract, which had been let to M&R’s Genrec – between January and March more than 6 000 modifications had to be made.

    But also, insufficient human resources had reportedly been mobilised for actual erection, which led to the appointment, in August, of Shanahan Engineering.

    Site logistics were also described as appalling, which had further delayed erection, as had serious welding errors, which were currently being remedied by the appointment of yet more foreign welders, mainly from Thailand, as well as the introduction of an orbital welding machine.

    The critical hydro-pressure test, which was scheduled for December 2011, would not take place this year. In fact, under the worst-case scenario, which was premised on the delivery performance to date, the pressure test would only take place in September 2012, which would result in first power in September 2013 and a ramp-up to full capacity over several months. Recent years, the machinery industry develops fastly, there are cone crusher, energy saving cone ball mill.

    Eskom was meeting weekly with Hitachi and there were various scenarios under discussion to improve delivery by between 10% and 50%. Should a 10% improvement be achieved, first power would arise in June 2012. Should it improve by 20%, the date would be brought forward to May 2013 and a 50% improvement would result in first power by March 2013.

    Hitachi Power Africa CEO Johannes Musel indicated recently that the first Medupi unit should be producing during the first half of 2013.

    Glanville is of the opinion that the after-tax value of Sangdong, after paying the 2% net smelter return royalty, is approximately US$300 million, within a reasonable range from US$200 million to US$400 million. This Valuation Opinion takes into account a 50% reduction from the calculated net present value, as the project Prefeasibility and Feasibility Studies are yet to be completed. Woulfe is on target to publish the Prefeasibility Study and the full Feasibility Study later this year.

    In the method used for this valuation, annual cash flows are projected over the expected life of the project, and these cash flows are then discounted at an appropriate rate to arrive at a Net Present Value. A comprehensive in-house cash flow model has been prepared and reviewed by Glanville. That comprehensive model has been utilized by Glanville to generate cash flow projections based on a number of different input parameters and assumptions, some of which are different from those utilized by Woulfe (including a higher estimated capital cost). Some of the key input assumptions include a sales price of US$375 per metric tonne unit of WO3 (in ammonium paratungstate), a twenty-one year mine life at an annual mill-feed production rate of 1.2 million tonnes, an average grade of 0.41% WO3, and an after-tax constant-dollar discount rate of 8%.

    Brian Wesson, CEO and President of Woulfe, commented, 'The Valuation Opinion is within the range we were expecting. We undertook this valuation to assist the Woulfe Board in evaluating potential transactions that may eventuate. With this document in hand, the Board will be in a better position to make decisions in the best interest of Woulfe shareholders.'

    As the information provided in the Valuation Opinion does not contain an economic analysis which conforms with National Instrument 43-101, the economic viability of Sangdong will remain uncertain until completion of at least the Prefeasibility Study, which is expected in a couple of months.

    As previously announced, the Company commissioned PricewaterhouseCoopers ('PwC') to undertake a valuation of Sangdong, and this valuation has been completed. However, due to the confidential nature of some of the information contained in the report by PwC, it will not be submitted to SEDAR. The conclusions of the PwC report are consistent with this Valuation Opinion.

    Woulfe Mining Corp. is a TSX-V listed company with a diversified portfolio of mining licenses for tungsten, molybdenum, gold, base metals and uranium-vanadium in South Korea. In China, Henan Hongxing is titled as 'China Famous Machinery Brand', there are series of machines, jaw crusher, impact crusher, ball press, ball mill, Raymond mill, limestone jaw crusher.

    The company is focused on the development of the Sangdong tungsten mine (one of the World's largest and most renowned tungsten mine's for 40 years) a property that we believe has substantial value for our shareholders. The outcome of the scoping study in March 2010 determined that the project NPV was US$467 million at a commodity price of $25,000 per tonne Ammonium Paratungstate (APT). Today, the APT price is over US$45,000 per tonne. Woulfe has accelerated the project due to the robust project and market. The company's target is to move to production at the end of 2012. In the last 18 months the company has focused on building the Sangdong tungsten mine team and reopening the mine. The project is well staffed with professionals and is moving forward rapidly.

    Neither TSX Venture Exchange nor its Regulation Services Provider (as that term is defined in the policies of the TSX Venture Exchange) accepts responsibility for the adequacy or accuracy of this release.

    World No. 2 iron ore producer Rio Tinto cited a strategy by bigger rival Vale to divert European shipments to China for a dramatic softening in market prices. Because of the iron ore prices, it affects the jaw crusher markets.

    Rio's iron ore division head and Australian chief executive Sam Walsh said a move by Vale to ship more to China had not caused Rio to curb its own iron ore production runs, which are running at full capacity.

    'The softening in iron ore prices relates to Vale shipping material that was destined for Europe into China,' Walsh told a business forum in Perth on Tuesday.

    Spot iron ore prices have shed 19 percent so far this month in a sell-off largely fueled by slower construction steel demand in China.

    China is the world's biggest customer of imported iron ore, accounting for around 400 million tonnes annually.

    In Europe, a more important market for Vale than Rio, steel markets have fallen under a cloud of doubt given its debt crisis.

    Growth of Europe's steel production will slow in 2012 along with activity in the steel-using sectors, Eurofer, the European steel producers association has forecast.

    Spot iron ore prices on Tuesday fell nearly 4 percent. It was the biggest single-day drop since August 2009 as thin demand from China forced some traders to sell at a loss.

    'Traders who can't hold positions because they don't have sufficient funding are selling at a loss of $40-$45 a tonne,' said a Singapore-based iron ore trader.

    Despite price falls, all three mega-producers including Rio are ramping up production. Many mining machinery prices such as ball mill, energy saving cone ball mill, impact crusher have changed greatly.

    'My business is shipping flat out,' Walsh said. 'We are producing at record rates.'

    Walsh downplayed the lasting effect of Vale's strategy.

    'There's a limit to what they can physically ship,' Walsh later told Reuters on the side of the forum. 'We're not overly concerned about that.'

    He said Rio remains confident in the long-term drivers of economic growth and iron ore demand in China.

    In the short term, the market was worried about the European crisis, but it was not having a direct impact on Rio's operations, he said.

    'The issue is contagion. It's perception, it's fears,' he said. 'When you look at the fundamentals of China, India, South Asia, North Asia, we find it's very robust.'

    Vale, the largest of the three top producers, reluctantly discarded the once-a-year-price system in 2010 only after BHP Billiton and Rio bowed out, cognisant it would upset customers. In the end it had no choice but to follow suit.

    Now, with spot prices trailing the last quarter's average price mark and lead times on Brazilian cargoes to China much longer than the Australian miners, Vale has announced it is open to alternative pricing systems.

    Some analysts have interpreted this as paramount to Vale offering discounted iron ore to boost sales.

    Affected by the earthquake, Japan heavy industry market meet the great losses, which brings the challenge and chance for China machinery market. Japanese steelmakers JFE Holdings and Sumitomo Metal Industries said on Tuesday they would not cancel their currently more expensive long-term iron ore purchasing contracts for October-December despite a plunge in prices on the spot market. We are the professional manufacturer of mining machinery, crushing equipment, sand making equipment, sand washer, roll crusher, rod mill.

    The comments came a week after Vale's chief executive said the Brazilian miner was open to discussing different iron ore pricing systems with clients, as a tumble in the price of ore has led to pressure from steel mills for more flexibility.

    Weaker demand for steel in China, the world's biggest consumer and producer, has dragged down steel prices and slashed the appetite for iron ore, the key steelmaking raw material.

    Some Asian steel giants have been pressuring suppliers as spot iron prices have slid to their lowest in a year and are set to post their biggest weekly decline in 15 months as demand from top importer China remains thin, fuelling expectations prices could drop further.

    Asian mills, with margins cut by lower steel prices, are not that keen on paying around $170 a tonne for iron ore -- the fourth-quarter contract rate based on June-August average spot prices -- when the current rate is around $145.

    Vale has told Chinese steelmakers it will give them options to buy the raw material cheaper, sources told Reuters this month, as spot prices for iron ore have dropped below the quarterly contract system created last year.

    But Sumitomo Metal Industries, which is set to complete a merger with Nippon Steel, the world's No.4 steelmaker, in October 2012, has not yet received offers from miners to change iron ore contract prices for the October-December quarter, a company official told Reuters.

    Grasp the chance to develop our mining machinery industry, expand our jaw crusher market, ball mill market and others.

    In the past practice of grinding technology, in the equipment making, people often only consider whether the basic working state o the equipment can meet the standard and output problem. With the requirement of energy saving and environmental production becomes more and more strict, the extensive production mode of original ball mill is not suitable for the high precision production need of present stage. Therefore, to achieve double bin classified grinding is necessary in the reforming of a ball mill, rod mill and other grinding mills.

    Then, how does this kind of ball mill achieve energy saving? From the view of the discharge and the feeding of raw materials, raw materials does not directly enter the inside medium of cylinder through the hollow shaft neck of double chamber ball mill, so the ball mill will not begin the selecting work until the cylinder rotates at a speed around a horizontal axis.

    The separation effects are mainly reflected in that bulk material fall into crushing chamber while smaller pieces of material fall into the grinding chamber through the conveying device. In this way, when their own gravity is larger than the centrifugal force, the materials will be disengaged from the inner wall of cylinder.

    By the further optimizing the feedback device of the ball mill grinding chamber we can see that we can easily capture the necessary feedback information through the feedback device without further transformation of the situation, which play a supplementary role in the separating warehouse of the ball mill.

    After the separating warehouse, the ball mill can be saving ball mill consumable, such as steel ball and lining board consumption.In addition, after the classified chamber the ball mill can play two different effect, one is crushing, the other is the grinding effect. It uses the inertial force of large equipment for crushing, which is the unique property of the classified chamber ball mill.

    Comprehensive comparison, the classified chamber type ball mill can save power consumption than traditional ball mill about 40%-50%. Through the power distribution circuit of supercharging effect, the start consumption decrease 3-5 minutes than beforce. While the entire production and the grinding efficiency increased 35%-45%. There are also ultra-fine Raymond ball mill, energy saving ball mill.

    Ball mill is one of the essential part of mineral processing equipment. Many users of ball mill complains that the liner plate of a ball mill is with short service life and a high production costs. Henan Hongxing Mining Machinery summed up key factors influencing the liner wear of a ball mil based on years of production experience, which as a reference for the users of ball mill. Hope it can help the users avoid a similar situation in production and prolong the service life of ball mill liner plate. The key factors influencing the liner wear of a ball mill generally include the following several points:

    1, The impact of media material

    The generally used crushing media mateial include: various mine materials (manganese, copper, tungsten ore, chrome ore, etc.), various types of stone (limestone, granite, gneiss, basalt, gray rock, etc.) and industry coal used in power. The hardness of the media is the main basis that determines the liner plate wear, the higher hardness of the media, the shorter service life of the liner, on the contrary, if the media is with a lower hardness, the service life of the liner will be prolonged.

    2, The impact of operating conditions

    1) Eliminate defects not timely.

    2) Adjusting undeservedly makes the ball mill running at a short positions.

    3, The impact of liner material

    The main parameters affecting the anti-wear effect is matching of the two index of hardness and impacting toughness of liner material. If the liner plate has a higher hardness, which means it has a good wear resistance, and the two factor basically is a proportional relationship. The impacting energy depends on the size of the diameter of steel ball and grinding tube.

    4, the impact of the ball mill's designing and manufacturing and the installing quality.

    The performance of the lining plate generally include the following two: one is to protect the cylinder; another is that the liner plate rotates at a specific speed to raise the ball to the required height to achieve the desired effect.

    The quality of the liner plate is also direct factor affecting the normal operation of the mill.

    Those above are the main factors affecting ball mill liners, we recommend that you should firstly consult the expert before you buy a ball mill. And you'd better go to the manufacturers with strength production and reputable brand purchase. You can contact us at any time for jaw crusher, ball press machine, untra fine jaw crusher.

    At present, there are various crushers: jaw crusher, cone crusher, hammer crusher, roll crusher, and the crushers can be classified into extrusion type, impact type, shear type according to the main crushing force.

    Extrusion type crushing machine mainly comprises jaw crusher, rotary crusher, cone crusher, roll crusher and so on. Its working principle is: materials crushed by the extrusion, splitting and bending force between the crushing mechanism fixed tooth plate and the movable tooth plate. This kind of crusher mixedly crush materials in the crushing cavity, which is vulnerable to the formation of pulverization and easy to form the big shape product, which can't ensure product particle size and with a large power consumption. This kind of crusher is mainly used for crushing hard materials in metal, mining, gravel field and other industries.

    Impact type crushing machine mainly comprises impact crusher, hammer crusher etc. This kind of crusher crush the coal by impacting with the hammer, after every impacting, the materials accelerating, then flying to the impact plate, shock, anti - shock, repeated by the same process, at the same time the materials after being hit mutually impact in the crushing cavity. This kind of crusher is difficult to control and which finally will lead to a mount of powder coal. It is worse to use this kind of method to crush the coal with higher fragility and lower hardness and it is strict with the size of the feeding. This kind of crusher is suitable for coarse and medium crushing materials.

    The crushing process of the key process in the coal dressing process and is also the important means to improve the technical and economic index of the coal dressing plant. Various forms of broken equipment, because of their different crushing mechanism, has different applicable scope and use. Choose a suitable crushing equipment you should according to the material properties and operational requirements. Accordingly, it is that different forms of crushing machine, because of its crushing principle is different, have different scope of application.

    According to the China Construction Machinery Business survey, 26 of the main manufacturers of excavators in China sold 8868 units in September, 23.86% down. Excavator cumulative increase since February of this year climbed to the highest point, it has been declining for several months. China Construction Machinery Industry Association has predicted the next five years, the construction machinery industry is expected to be 17% annual growth. But now the growth target is being challenged. Growth in the second quarter of this year began the rapid decline in construction machinery industry had still not out of the signs down, the industry growth is still in the 'bottom.' Affected after construction machinery enterprises are expanding production capacity is becoming excess capacity.

    Excavator sales decline in a row is typical of China's construction machinery industry reflected. According to industry experts say, since the second quarter this year, sales of construction machinery industry continued to decline, this phenomenon has not been checked in the third quarter. Zoomlion Chairman Zhan Chun new that the growth rate of decline in construction machinery industry, there have been signs of late last year, the first quarter of this year, industry unexpectedly explosive growth has actually overdrawn market demand, sales of construction machinery starting from the second quarter, a marked decline in . Railway construction slowdown, real estate is the construction machinery industry sales for the decline. Data show that the Ministry of Railways to complete the first nine months of capital construction investment 346.879 billion yuan, down 19.3%. National Railway in the third quarter ended investment for years the Great Leap Forward.

    In the industry under the background of slowing demand, the domestic construction machinery industry excess capacity problem increasingly prominent. And 'excess capacity' has become the focus of engineering machinery industry conference topics. ZhanChunXin the truth, construction machinery industry excess capacity are triggering industry malignant competition. Xugong group President and general manager of the rabbit liugong zeng pins identity construction machinery has appeared excess capacity. However, they think, industry excess capacity is the low end products of the excess, in high-end products field still have space. Four trillion yuan investment by pulling, engineering machinery industry become fast development, the related businesses expand the capacity to increase investment. A shares the main engineering machinery listed companies have or are almost through shares expand the capacity of financing. International experts will China enterprise overcapacity called it 'assembly excess capacity'. In order to deal with excess capacity bring industry competition, some large engineering machinery enterprise is calling on industry management department to make the industry standard, to regulate the market competition.

    As the professional manufacturer of complete sets of mining machinery, such as single-stage hammer crushersand makercone crusherrod mill, Henan Hongxing is always doing the best in products and service.

    Er zijn nog een hele reeks extra mogelijkheden en functionaliteiten die u kan gebruiken voor uw blog. Log in op http://www.bloggen.be/ en geef uw gebruikersnaam en wachtwoord op.  Klik vervolgens op 'Instellingen'.  Daar kan u een hele reeks zaken aanpassen, extra functies toevoegen, enz.

    WAT IS CONCREET DE BEDOELING??
    De bedoeling is dat u op regelmatige basis een bericht toevoegt op uw blog. U kan hierin zetten wat u zelf wenst.
    - Bijvoorbeeld: u heeft een blog gemaakt voor gedichten. Dan kan u bvb. elke dag een gedicht toevoegen op uw blog. U geeft de titel in van het gedicht en daaronder in het bericht het gedicht zelf. Zo kunnen uw bezoekers dagelijks terugkomen om uw laatste nieuw gedicht te lezen. Indien u meerdere gedichten wenst toe te voegen op eenzelfde dag, voegt u deze toe als afzonderlijke berichten, dus niet in één bericht.
    - Bijvoorbeeld: u wil een blog maken over de actualiteit. Dan kan u bvb. dagelijks een bericht plaatsen met uw mening over iets uit de actualiteit. Bvb. over een bepaalde ramp, ongeval, uitspraak, voorval,... U geeft bvb. in de titel het onderwerp waarover u het gaat hebben en in het bericht plaatst u uw mening over dat onderwerp. Zo kan u bvb. meedelen dat de media voor de zoveelste keer het fout heeft, of waarom ze nu dat weer in de actualiteit brengen,... Of u kan ook meer diepgaande artikels plaatsen en meer informatie over een bepaald onderwerp opzoeken en dit op uw blog plaatsen. Indien u over meerdere zaken iets wil zeggen op die dag, plaatst u deze als afzonderlijke berichten, zo is dit het meest duidelijk voor uw bezoekers.
    - Bijvoorbeeld: u wil een blog maken als dagboek. Dagelijks maakt u een bericht aan met wat u er wenst in te plaatsen, zoals u anders in een dagboek zou plaatsen. Dit kan zijn over wat u vandaag hebt gedaan, wat u vandaag heeft gehoord, wat u van plan bent, enz. Maak een titel en typ het bericht. Zo kunnen bezoekers dagelijks naar uw blog komen om uw laatste nieuwe bericht te lezen en mee uw dagboek te lezen.
    - Bijvoorbeeld: u wil een blog maken met plaatselijk nieuws. Met uw eigen blog kan u zo zelfs journalist zijn. U kan op uw blog het plaatselijk nieuws vertellen. Telkens u iets nieuw hebt, plaats u een bericht: u geeft een titel op en typt wat u weet over het nieuws. Dit kan zijn over een feest in de buurt, een verkeersongeval in de streek, een nieuwe baan die men gaat aanleggen, een nieuwe regeling, verkiezingen, een staking, een nieuwe winkel, enz. Afhankelijk van het nieuws plaatst u iedere keer een nieuw bericht. Indien u veel nieuws heeft, kan u zo dagelijks vele berichten plaatsen met wat u te weten bent gekomen over uw regio. Zorg ervoor dat u telkens een nieuw bericht ingeeft per onderwerp, en niet zaken samen plaatst. Indien u wat minder nieuws kan bijeen sprokkelen is uiteraard 1 bericht per dag of 2 berichten per week ook goed. Probeer op een regelmatige basis een berichtje te plaatsen, zo komen uw bezoekers telkens terug.
    - Bijvoorbeeld: u wil een blog maken met een reisverslag. U kan een bericht aanmaken per dag van uw reis. Zo kan u in de titel opgeven over welke dag u het gaat hebben, en in het bericht plaatst u dan het verslag van die dag. Zo komen alle berichten onder elkaar te staan, netjes gescheiden per dag. U kan dus op éénzelfde dag meerdere berichten ingeven van uw reisverslag.
    - Bijvoorbeeld: u wil een blog maken met tips op. Dan maakt u telkens u een tip heeft een nieuw bericht aan. In de titel zet u waarover uw tip zal gaan. In het bericht geeft u dan de hele tip in. Probeer zo op regelmatige basis nieuwe tips toe te voegen, zodat bezoekers telkens terug komen naar uw blog. Probeer bvb. 1 keer per dag, of 2 keer per week een nieuwe tip zo toe te voegen. Indien u heel enthousiast bent, kan u natuurlijk ook meerdere tips op een dag ingeven. Let er dan op dat het meest duidelijk is indien u pér tip een nieuw bericht aanmaakt. Zo kan u dus bvb. wel 20 berichten aanmaken op een dag indien u 20 tips heeft voor uw bezoekers.
    - Bijvoorbeeld: u wil een blog maken dat uw activiteiten weerspiegelt. U bent bvb. actief in een bedrijf, vereniging of organisatie en maakt elke dag wel eens iets mee. Dan kan je al deze belevenissen op uw blog plaatsen. Het komt dan neer op een soort van dagboek. Dan kan u dagelijks, of eventueel meerdere keren per dag, een bericht plaatsen op uw blog om uw belevenissen te vertellen. Geef een titel op dat zeer kort uw belevenis beschrijft en typ daarna alles in wat u maar wenst in het bericht. Zo kunnen bezoekers dagelijks of meermaals per dag terugkomen naar uw blog om uw laatste belevenissen te lezen.
    - Bijvoorbeeld: u wil een blog maken uw hobby. U kan dan op regelmatige basis, bvb. dagelijks, een bericht toevoegen op uw blog over uw hobby. Dit kan gaan dat u vandaag een nieuwe postzegel bij uw verzameling heeft, een nieuwe bierkaart, een grote vis heeft gevangen, enz. Vertel erover en misschien kan je er zelfs een foto bij plaatsen. Zo kunnen anderen die ook dezelfde hobby hebben dagelijks mee lezen. Als u bvb. zeer actief bent in uw hobby, kan u dagelijks uiteraard meerdere berichtjes plaatsen, met bvb. de laatste nieuwtjes. Zo trek je veel bezoekers aan.

    WAT ZIJN DIE "REACTIES"?
    Een bezoeker kan op een bericht van u een reactie plaatsen. Een bezoeker kan dus zelf géén bericht plaatsen op uw blog zelf, wel een reactie. Het verschil is dat de reactie niet komt op de beginpagina, maar enkel bij een bericht hoort. Het is dus zo dat een reactie enkel gaat over een reactie bij een bericht. Indien u bvb. een gedicht heeft geschreven, kan een reactie van een bezoeker zijn dat deze het heel mooi vond. Of bvb. indien u plaatselijk nieuws brengt, kan een reactie van een bezoeker zijn dat deze nog iets meer over de feiten weet (bvb. exacte uur van het ongeval, het juiste locatie van het evenement,...). Of bvb. indien uw blog een dagboek is, kan men reageren op het bericht van die dag, zo kan men meeleven met u, u een vraag stellen, enz. Deze functie kan u uitschakelen via "Instellingen" indien u dit niet graag heeft.

    WAT IS DE "WAARDERING"?
    Een bezoeker kan een bepaald bericht een waardering geven. Dit is om aan te geven of men dit bericht goed vindt of niet. Het kan bvb. gaan over een bericht, hoe goed men dat vond. Het kan ook gaan over een ander bericht, bvb. een tip, die men wel of niet bruikbaar vond. Deze functie kan u uitschakelen via "Instellingen" indien u dit niet graag heeft.


    Het Bloggen.be-team wenst u veel succes met uw gloednieuwe blog!
