Cement plant is usually located closely either to hot spots in the market or to areas with sufficient quantities of raw materials. The aim is to keep transportation costs low. Basic constituents for cement (limestone and clay) are taken from quarries in these areas.

Cement ball mill is also named natural material mill, material grinding mill and clinker mill, is key equipment for grinding following the concrete crush process, which can be trusted in the manufacture industries, including cement, silicate, new building materials, refractory material, fertilizer, ferrous metal, nonferrous steel and glass ceramics, etc. Cement ball mill may be used for the dry and wet grinding for all kinds of ores as well as other grind-able materials. Based on different materials and discharging methods, there are dried up cement ball mill and wet ball mills for option.

Cement Manufacturing Process

1). The dry cement process consists of many simultaneous and continuous operations using some of the largest moving machinery in manufacturing. Over 5000 sensors and 50 computers allow the entire operation to be controlled by a single operator from a central control room.

2). The limestone is combined with clay, ground in a crusher and fed into the additive silos. Sand, iron and bottom ash are then combined with the limestone and clay in a carefully controlled mixture which is ground into a fine powder in a 2000 hp roller mill.

3). Next, the fine powder is heated as it passes through the Pre-Heater Tower into a large kiln, which is over half the length of a football field and 4.2 metres in diameter. In the kiln, the powder is heated to 1500 degrees Celsius. This creates a new product, called clinker, which resembles pellets about the size of marbles.

4). The clinker is combined with small amounts of gypsum processing, limestone and finely ground in a finishing mill. The mill is a large revolving cylinder containing 250 tonnes of steel balls that is driven by a 4000 hp motor. The finished cement is ground so fine that it can pass through a sieve that will hold water.

5). The cement mill process begins when limestone, the basic raw material used to make cement, is transported by rail to the Edmonton plant from the Cadomin limestone quarry 220 kilometres west of Edmonton.

Machinery industry is one of the industries that are directly related to the industrialization level of our country. At present, China has been one of the leading powers of mining machinery manufacture, but it still has a long way to go to be an industrial power. Machinery industry is the pillar industry and the promising industry that our country focuses on supporting and promoting. So as the leading industry of mining machinery, crusher industry benefits a lot. Of course, our final purpose is to carve a niche for China's machinery industry in the international market, which of course is a slow process. So the crusher enterprises should not reach for what is beyond your grasp, and should primarily gain a foothold in domestic market.

Mining machinery is the development of the modern science and technology and the overall industrial level is closely linked, especially and mechanical engineering science and mining the academic development are closely linked. Mechanical engineering science and the general trend of development will be digital, intelligent, precision, miniaturization, life and ecosystemizing. Mining machinery as mechanical engineering discipline is a branch of, also follow the general trend of development.

The manufactures that engage in mining machinery are countless, and the internal competition is also very intense. While, not all the all the product qualities are the same, so the investors should polish eyes in purchasing the equipment, and choosing the most suitable one. Basing on domestic market, crusher manufacturers should actively hunt for more home customers and focus on the areas that are relatively remote and backward, for they need building road and railways, so crusher will be greatly needed in there.

With the thorough implement of the concept of environmental protection, many technologies are applied in production, for example, in the year of 2009, hybrid power was introduced in the energy conservation study of mining machinery and developed the first new tape jaw crusher whose energy conservation ability is 30% of the traditional one, and with higher efficiency and productivity.

During the operation of mining machinery, more dust is produced, which will have a severe pollution to the environment around. Therefore, the investors should consider dust-cleaning apparatus during selecting equipments.

In conclusion, the development of any industry can not be completed overnight, neither do the crusher industry. Mining machinery enterprises should constantly innovate, gather experience, do well in brand strategy, and take the leading position in the ever-changing market.

Henan Hongxing always stick to the entrepreneur idea that business reputation comes first, and we still carry out the service purpose of customer satisfaction and follow the business principle of “quality is the most important and our customers are God”, for this reason, Hongxing Brand mining equipment frequently is exported to the_middle East, South Africa and the Southeast Asia and is well received by customers.

Driving method of domestic over ball mill:

(1) It is driven by synchronous motor; Large-type adopts low-speed synchronous motor to directly drive the small pinion of ball grinder, and the small pinion will propel the big geared ring to make the ball machine rotate. Its advantages are of high transmission rate, low coverage size, easy maintenance and improved power grid rate coefficient, but the most is pretty expensive and needs direct electricity current.

(2) It is driven by asynchronous dynamo pinion speed lower sand maker machine. As for large and_middle sized ball grinder, it will adopt asynchronous driving method. The pinion speed lower machine drives the small pinion and big geared ring to rotate the whole equipment. Its_characteristics are that it cost less, but a whole complete set of big-size speed slower equipment is necessary.

(3) By asynchronous machine triangle belt. Small sized device uses asynchronous machine to put the tooth tyre in motion by way of triangle belt, but it has such disadvantages as low transportation capacity, big coverage size and complicated repair.

For foreign equipment:

They are mainly using the following three methods:

Firstly by way of little bit sized tooth tyre and big tooth ring; secondly central promotional mode, that is to say, the motor drives the prolongation part of the hollow shaft neck by way of the speed lower, and the last but not the least, the rotator is directly installed onto the prolongation part of the barrel or the hollow shaft neck, the determinant is fixed onto the ground, thus forming a so-called “gearless promotion”. For the time being, the hammer crusher machine adopts super low speed synchronous motor whose rotating speed is just the same as the whole equipment so that it is suitable for devices with rate more than seventy-five hundred kw.

Too often, teams are formed merely by gathering some people together and then hoping that those people somehow find a way to work together. Teams are most effective when carefully designed. For this reason, on 8th April 2010, a vibrant spring day, Henan Hongxing Mining Machinery CO.,Ltd organized an internal training activity. In the multi-purpose function room of company headquarter located in Zhengzhou city, the trainees from all departments learned attentively, discussed with each other and studied from each other. We tried our best to combine listening and learning, integrate study and application.

As an old saying goes, 'The whole year's work depends on a good start in spring.' So always plan your year in spring and your day at dawn.

The term 'reporting to one boss' can be a misleading one. In a well-designed organisational structure, people reporting to one boss do often form a team. But reporting lines are frequently designed within the constraints of grading structures. Of necessity, there is often a compromise between the need for traditional reporting lines, and grouping people together who are a team. In reality, team structures are often complicated, and people can be members of several teams, because a team is a group of people working together towards a common goal. So we give a complete training class about our product such as ball mill and other China professional jaw crusher.

As much as possible, include input from other members of the organization when designing and wording these goals. Goals might be, for example, “to produce a project report that includes a project plan, schedule and budget to develop and test a complete employee performance management system within the next year.” Write these goals down for eventual communication to and discussion with all team members.

The employees collaborated with each other and learned relevant knowledge hard. Through the training, all the staff not only improved their own skills and their understanding of company administration system but also had a deeper comprehension of us Hongxing Machinery’s policy that surviving on quality hammer crusher machine and developing through science and technology and company philosophy that virtue comes ahead of business and profit comes after customers.

Throughout the 25 years’ development, Hongxing Machinery has hold to the staff training plan of cultivating ordinary staff into outstanding talents. The achievements, experience and lessons gained in in the process of company progression themselves would be great training material for us. In future training we will work harder to make every staff gain greater improvement in daily work. We have the faith that in the positive atmosphere we RedStar people are sure to build a world of our own and create new splendors.

We are in the belief of 'Unity is strength'. Baxia for our bright future!

At any times, there are unique features in the development of one thing. For business circles, the characters are more and more complex. Next, let's analyse the main features of the development of Machinery Industry.

1: The basic station

The developed countries pay much attention to the development of equipment manufacture industry, which is in the top place of the proportion, accumulation, employment and contribution and provide the important material base for the new technology, development of new products and manufacture for the equipment manufacture industry, so it is the indispensable strategic industry of the modern economy. Even the industrialized countries entering information society all pay much attention to the development of machine manufacture industry.

2: Scale economy

The globalization manufacture has become the developing mainstream of the transnational companies. At the same time of regrouping and competition expansion, the big enterprises strengthen the investment and development for the operation to increase whose set capacity of system, individuation and diversification to adapt the market.

3: Imbalanced development

Taking 2003 as an example, 99% of top 500 enterprises are from North America, Asia and Europe, which shows that the three continents are in the incomparable governing place in the industry of world machine.

4: Deepening structure adjustment and change in the manufacture mode and management mode

The developed countries strengthen the industry transfer and the machine products with low adding value are arranged to be manufactured in the developing countries with potential requirements. To meet the change of market requirement, big manufacturers adopt professional manufacture and single product with large quantity becomes the new characteristic of the manufacture mode among top 500 enterprises and at the same time, the traditional manufacture mode is changing to the customer-oriented. The individuation of service is the main factor for the competition.

5: The new change of the mode in the industry of machine manufacture

There are two kinds of traditional globalizations: one is to regard own country as the manufacture base and sell products to other countries and the other is to invest and build manufacture base in other countries and manufacture there and sell products to own country or other countries. The characteristics are: to own the manufacture facilities and technology and manufacture products by self and for using the resources, only to use the raw materials, personnel and fun from host countries.

With the development of information technology, the management mode changed fundamentally and the organization mode changed accordingly. These changes happened in the transnational companies and will keep on developing as a new mode of globalization. The characteristic of this change is to widely use other countries’ manufacture facilities and technology strength to manufacture products and sell to all over the world. The companies of machine manufacture industry set up processing network of parts all over the world and take charge of the installation and marketing of the products. The preparation of raw material and globalization of parts become the developing trend for the world machine manufacture industry.

6: The transnational purchase in the machine manufacture industry is intense

The modern purchase doesn’t only lay emphasis on the competition and association of strong companies is the main method to gain competitive advantages, which is the big character for the machine manufacture industry to gain development. Now the market competition is intense and invest for building factory is in big risk, so many enterprises choose the combination and purchase. On the premise of building factory, to optimize the product structure to increase throughput, expand market share and gain scale efficiency is the best way. The industries with high technology have the threat from technology innovation, so only by the association, can enterprises become stronger. The strategic purchase in the machine manufacture industry leads to the new deployment of the resources and the cooperative situation of the competition appears.

7: Products with high technology

The development of modern science and technology with the information technology puts forward higher and new requirements for the machine manufacture industry. All the countries and areas and especially the developed countries lay emphasis on the development of machine manufacture, which shows that as the high and new industry, the machine manufacture industry plays an important and indispensable role in promoting the social technology progress and industry upgrade. The fast development of the high and new technology plays the role of driving, upgrade and alternation. The achievements of high and new technology, such as information equipment technology, industry automatization technology, digital-control process technology, robot technology, advanced electricity technology, electron and electric power technology, new material technology and environmental protection technology are widely used in the machine industry and the technology content is the key for the market competition.

There is something very basic about manufacturing – value is added by taking raw materials and labor, and producing products that can be sold in high quantities, with quality, to generate good return on the investment.

The manufacturing sector remains significant in leading economies worldwide, but faces major issues such as cost competitiveness, product innovation and how to compete in an increasingly global market. That people live and work in peace and contentment can not be realized without a country’s prosperity, a nation’s prosperity and people’s strength can not come true without economic development and economic advancement can not go without development of science and technology, and it will promotes macroeconomic development through penetration and influence of production factors. As we all know that productivity includes labor means, labor object and worker which are all indispensible.

Of course, innovative design and product development are important to generate competitive advantage. But design and development can be done in locations that are not necessarily tied to the production plant. Intel, for example, builds semiconductor fabrication plants in many different worldwide locations. Likewise, many automation companies build products wherever it suits their business needs. Hongxing Machinery as the leading manufacturer of jaw crusher and China professional sand maker will certainly not lose its stand.

During the past decade or so, it seems clear that manufacturing is tending to migrate away from the U.S. for a variety of factors, not the least being that manufacturing appears to have a negative image. PLC inventor, technology guru and author Dick Morley suggests that the idea that manufacturing rotary kiln is somehow bad has caused jobs to be driven out. He suggests that no community in North America really wants a new assembly plant, a printed board facility or a semiconductor enterprise. In television dramas the villain is the businessman, and the hero is the scrubby squatter who fights to prevent progress.

In modern economy, with the incessant growth of economic level, more and more industries develop into groups, among which metallurgy, machinery processing business, coal crushing and sand maker, chemistry and mining industry significantly drive the adjustment of industrial structure. So science and technology is the sufficient and necessary condition of economic development and economic improvement will not be possible without it.

In a recent survey of Chinese and U.S. manufacturers by Industry Week, 54% of Chinese companies cited innovation as one of their top objectives, while only 26% of U.S. respondents did. Chinese companies spend more on worker training and enterprise-management software. And 91% of U.S. plants are more than a decade old, vs. 54% in China.

At present, the Chinese government holds about 10% of outstanding U.S. Treasury securities, second only to Japan. Most people feel that the Yuan is undervalued by about 30% and a revaluation will devalue China's U.S. debt by a third. Unless it simply accepts a devaluation of this huge debt, China will surely be using this cash to do a lot more deals in the U.S.

As we all know, crushing of material is a technical process that is widely used in the industry departments like metallurgy, mining, construction, chemistry, electricity and road construction. Through many years’s practice and conclusion and the purpose principle of crushing and grinding, it shows that strengthening the crushing and trying to decreasing the feeding size is the important method of improving the grinding efficiency and reducing the ore dressing cost. For this reason, reducing the cost and increasing economic profit is the starting point and the crusher has been developing in the direction of fine breaking and high efficiency and low energy consumption. In addition, with the constant development of science and technology, the size of mining exploitation is becoming larger and larger and the breaker is also developing more and more large-sized.

As an old saying goes, “first-class enterprise focus on brand, second-class on market, and third-class on product”. Quality brand can bring good public praise in the industry. In recent years, brand awareness of Chinese engineering machinery users has been improving sharply. So when a brand is accepted by the customers and printed into their heart, then its place is difficult to be superseded. As for mining equipment band, in order to take up the market, it firstly should take up some place in the heart of the customers, and one key is band improvement. The existing commonly-used crushers include impact crusher and cone crusher.

We can see from the above two phenomena, if a company wants to enjoy popular support, he should firstly analyze the client’s need and find the product development direction and secondly should improve product and service quality and build his own independent band. Building a branding is building the image of the enterprise and make this image take root in users’heart. In this way, when the competition becomes fierce, the big band that is accepted by the users will survive even without fighting.

The superficial sales is just simply selling several products, but the high level of selling is to promote his own brand. Only by popularizing his own brand can he win over ceaseless clients.

Hongxing Machinery is just a kind of such mining machinery company that regards quality as life and has built internationally famous brand like ore benefication machine. Here in our company, the customers are the God, and we always follow the quality principle that we hold responsible for every production process and for every client. Everything that we are now doing is for your consideration because we are deeply convinced that quality is the gold key to market.

According to the industry policy that our country will give significant support to the development of basic industry like energy, transportation and raw material, as the backbone of these basic industries, mining machinery should get prior support so that it can further develop and improve in order to provide more crushing and grinding machines with international advanced level for the exploitation of coal, metal and non-metal mining hill, and satisfy the demand of energy and raw material of national economic development. The mining equipment mainly includes jaw crusher, sand maker and powder-grinding machine, among which crusher is the most important link in the whole rock crushing process and also the important symbol of measuring the strength of the mining facilities manufacturing industry.

Mining breaking and grinding machinery is devices that have high technology content and integration and the development of new equipment is mixed together with more and more achievements from other business scopes. With the development and advancement of material science, information technology and computer technology, every round of products are injected with new techniques, the update cycle of spare part is becoming shorter and shorter and the upgrading of new equipment is becoming faster and faster. Especially for the development of large-sized mining equipment, because there is no mature experience that can be learned and any mistake is allowed, it has to be researched with the help of mixing with many discipline techniques, improve the design efficiency and quality and enhance the company’s independent innovation ability and market competitiveness. The rock crushing and grinding devices has formed a trend of digital development with the basis of computer and internet technology.

When we look back on the development history of crusher, we can conclude that the main breakers are vertical impact crusher, hammer breaker and so on. Since the types are too many, their names are different.

The impact crushing machine developed by Henan Hongxing Mining Machinery is the example that perfectly combined with professional breaking technology and engineering manufacture and also the sufficient representation of new technique and processing method. It not only can provide the best rock aggregate for the highway, railway, high building, municipal works, hydroelectric dam construction, port and wharf and concrete mixing station, but becomes the core equipment in the artificial sand making industry and stone transformation scope, and more and more becomes the mainstream machine in the business scope of metal rock breaking, quartz sand production and slag disposal. So this series of products are well received by customers from home and abroad at the same time.

Conveyor, also named as transmitter, is a rubber and fiber and metal combination product that is used for loading and conveying materials. It is widely applied for transporting various kinds of solid material and powder materials. Conveyor can continuous, high efficiency, big obliquity transportation, and the safe operation, easy to use, easy maintenance, low freight and shortened the distance transportation, reduce the construction cost, save manpower. The daily use of the more is to pay attention to press a regulation strictly operation, and the daily maintenance are mainly used for the protection of the environment and the hardware to prevent the destruction of the system software. Programmable logic controller is functions of the logic control. It will come from all kinds of sports and function of the conveyor instruction in logical order, so they can accurately, coordination and orderly safety operation. In the meantime, it can send many kinds of information from the tools and working state to the transmitter and timely and exactly give further control order, in which way the control of the whole belt conveyor can be realized.

Speed by container in central usually main shaft and the speed of the motor machine to complete. It will motor speed matching into actual voltage value back to servo drive system as speed feedback signal, and instruction speed compared voltage value, so as to realize the precise control of the speed. Zhengzhou red star machinery factory specializing in the production of drum dryer, sand the dryer, drum dryer, sand drying apparatus mine machine equipment, the company relies on a strong research and development and production strength, has become one of the few domestic crushing, system of mechanical sand export base. Here should pay attention to the non-timing feedback voltage matching connection, and do not remove speed measuring machine. The cause of the speed control are due at the non-timing feedback line or break line be caused by. The central position of the earlier machine tool use linear or circular synchronous sensors or rotating transformer, and modern machine tools themselves

With grating feet and digital pulse coder as position central components, they coordinate transformation of machine tool in the operation of the actual position directly or indirectly central, will be the central values to Henan vibrating screen and feedback with instruction compared to coordinate the displacement until instruction position, so as to achieve precise control of the position. Position loop possible fault for more hardware failure, such as position central components to be contaminated, wire connection problem and so on.

At present, there are more than forty companies that are manufacturing vertical drying machine. When choosing such a device, many customers only pay attention to its superior characteristics but not give attention to its limits, because any kind of machinery has it own application scope but nor all-purpose applicable. For this reason, many problems occurred in its using process, and to make things worse, some equipment is idled even after using for several months.

1. First problem is very common, that is when purchasing, and the specifications of the dyer machine is too small. In a cement plant in Sichuan Province, the company purchased from a manufacturer, the production company said that the production capacity can reach twenty tons every hour, but in actual use, the output ability is only fifteen tons for each hour. When we look into the reasons, we find that the manufacturing enterprise purposely decrease the specifications with the view of successfully doing the business with low prices which in the end brings loss to the using corporation.

2. Material baking is not stem, yield of not to come. Material baking not stem, in drying slag moisture content is lesser, the effect is good, if baked some, such as clay, fly ash, etc material especially prominent. A cement plant in Yunnan choose a company a φ 2.2 * 14 in the purchase, production manufacturer when baked clay speak up to 15 tons /, the actual production of only 5 tons /, the contrast is bigger. Investigate its reason:

(1) moisture content really is on the high side, stay time enough;

(2) the drying system equipment is not reasonable, can not be education moisture;

(3) manufacturers can't master good drying original parameters.

PF series impact crusher is widely used in various metallic and nonmetallic ores, cement, abrasive material, glass, construction material, machine-made sand, metallurgy, etc. Impact crusher is also applicable to crush various stones with different hardness in medium and fine crushing area, such as used in iron ore crushing plant, non ferrous metal, emery, bauxite, quartz sand, basalt, etc. PF series impact crusher for sale is usually used in secondary crushing processing, subsequent the primary crusher-jaw crusher.

Since ground minerals are the major raw-materials used in various items like ceramic industries, Chemical, Metallurgical industries etc, the industrial demand of these products is ever increasing all over the country. Despite the fact that there are many registered and non-registered units operating in the country, there is enough scope to later the need of industrial sector. Reportedly, these are so many supplier’s traders and agents who supply the ground minerals to the existing industries from outside the state. Hence a stiff market competition in this sector is never ruled out. But maintenance of customer’s specification to their satisfaction uniform quality, supply schedules and payment terms are the key to open vast marketing opportunities for new unit in this field.
