In 21st century, 'low-carbon economy' is becoming recognized by the countries as the economic development model, China is no exception, the rapid development of economy and deteriorating environmental damage has brought unprecedented challenges to China's sustainable development and construction, the Government has to increase environmental protection legal system, to improve the low carbon environmental policy and law, to promote the harmonious development of low-carbon economy. In mining machinery industry, roll crusher as one of the key equipment also should suitable for the concept of low-carbon economy.

The coal industry began to introduce high efficiency and energy saving roll crusher to respond to the government call on environmental protection. More and more industries began to pay attention to energy saving and environmental protection. This is a challenge for most crusher manufacturers. The low consumption and green roll crusher equipment is the tendency in the future. In order to meet the need of consumers and respond to environmental protection call, Hongxing produced series of roll crusher machine with low carbon energy saving, green and environmental friendly. The new type roll crusher is widely used in coal, cement, silicate and other industrial department. The roll crusher can be divided into plain roller and tooth surface roller. The former used for grind material with medium hardness, the latter used for crushing brittle and soft materials.

The Roller crusher can be classified into double roller crusher and four roller crusher according to the roller quantity. The Roller Crusher bears the features of stable operation, easy maintenance, low cost, output size adjustable. The Roller Crusher can be used in the processing of fragile materials in cement, metallurgy, chemical, power generation, coal industries.

Working Principle Of Roller Crusher:

Through the feed opening, the raw materials fall to between the two rollers, after crushed, the final products drop naturally. When there are unbreakable materials or the material is too hard, the roller will concede automatically under the effects of spring and hydraulic pressure, which will widen the clearance between the rollers and make the hard or unbreakable so as to avoid damaging the machine. The clearance between the two rollers can be adjusted to change the sizes of final products.

There is a specific operating speed for most efficient grinding. At a certain point, controlled by the Mill speed, the load nearest the wall of the cylinder breaks free and it is so quickly followed by other sections in the top curves as to form a cascading, sliding stream containing several layers of balls separated by material of varying thickness. The top layers in the stream travel at a faster speed than the lower layers thus causing a grinding action between them. There is also some action caused by the gyration of individual balls or pebbles and secondary movements having the nature of rubbing or rolling contacts occur inside the main contact line. A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints.

For the most efficient results, the Mill should be at least half filled with grinding media. Some operators prefer to go a little beyond the halfway mark to compensate for wear. There is no objection to this and we have been suggesting a limit of about 5 percent.

Cement ball mill rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles and stainless steel balls. An internal cascading effect reduces the material to a fine powder. Industrial ball mills can operate continuously, fed at one end and discharged at the other end. Large to medium-sized ball mills are mechanically rotated on their axis, but small ones normally consist of a cylindrical capped container that sits on two drive shafts (pulleys and belts are used to transmit rotary motion). A rock tumbler functions on the same principle. Ball mill manufacturers are also used in pyrotechnics and the manufacture of black powder, but cannot be used in the preparation of some pyrotechnic mixtures such as flash powder because of their sensitivity to impact. High-quality ball mills are potentially expensive and can grind mixture particles to as small as 5 nm, enormously increasing surface area and reaction rates. The grinding works on the principle of critical speed. The critical speed can be understood as that speed after which the steel balls (which are responsible for the grinding of particles) start rotating along the direction of the cylindrical device; thus causing no further grinding.

The grinding efficiency of the one-half charge is considerably greater than for the one-third and, therefore it ca be expected that power consumption per gallon output will actually be less than with the smaller charge.

Grinding media should be periodically checked. Reduction in the quantity and size of the grinding media will result in poor grinding. We suggest a maximum schedule of once every six months, but any established procedure should be decided by individual experience. In some cases, where abrasive materials are involved, once a month is not too often and, in a few cases, even shorter intervals are indicated.

The ball mill is a key piece of equipment for grinding crushed materials, and it is widely used in production lines for powders such as cement, silicates, refractory material, fertilizer, glass ceramics, etc. as well as for ore dressing of both ferrous non-ferrous metals. The ball mill can grind various ores and other materials either wet or dry. There are two kinds of ball mill, grate type and overfall type due to different ways of discharging material. There are many wet ball mill suitable for use in a ball mill, each material having its own specific properties and advantages. Key properties of grinding media are size, density, hardness, and composition.

Aside from common ball mills there is a second type of ball mill called Planetary Ball Mill. Planetary ball mills are smaller than common ball mills and mainly used in laboratories for grinding sample material down to very small sizes. A used ball mills consists of at least one grinding jar which is arranged eccentrically on a so-called sun wheel. The direction of movement of the sun wheel is opposite to that of the grinding jars (ratio: 1:-2 or 1:-1 or else). The grinding balls in the grinding jars are subjected to superimposed rotational movements, the so-called Coriolis forces. The difference in speeds between the balls and grinding jars produces an interaction between frictional and impact forces, which releases high dynamic energies. The interplay between these forces produces the high and very effective degree of size reduction of the planetary ball mill.

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.

Since 2000, in the domestic basic industry and infrastructure development the incomes of mining machinery products, including crusher, the sand, the market demand machine etc, gross industrial output value and sales growth speed stability in 32% 40%. The market demand in the drive mining machinery manufacturing to economic growth, promote the whole industry more progress of technology, enhance the participation in international competition ability, our country mining machinery industry in international mining project construction is playing a greater role.

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.

Hongxing Mining Machinery mining machinery Co., LTD is specialized in producing crusher, grinding machine, feeder, vibrating screen , belt conveyor, mining machinery and equipment, the company of continuous efforts, the satellite become outstanding product quality.

And the size of the feeding particle can be 125mm ~ 1020mm. Jaw crusher can crush materials with a compression strength no more than 320Mpa, and it has a greater yield compared with similar products. The crushing method of jaw crusher is curved extrusion, the motor drives the belt and pulleys to make the jaw plate move up and down through the eccentric shaft. when the dynamic jaw rise, angle between the elbow plate and the dynamic jaw becomes larger, thus promoting the dynamic jaw plate close to the static jaw plate, and at the same time the limestone is extruded, rubbed, ground to achieve the crushing effect; when the dynamic jaw move down, the angle of toggle plate and the static jaw will become smaller, the static jaw plate will be far from the dynamic jaw plate at the function of the rod and the spring, at which time the crushed limestone will discharge from the mouth under the crushing chamber. And realize the volume production of the limestone along with the continuous rotation of the motor crusher periodic crushing and discharging. After many tests and improvements, jaw crusher break the crushing mode of hammer crusher which crush materials by directly impacting with the hammer of hammer crusher . And realize the aim of reducing the energy consumption.

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.

At present, our country magnetic separation machinery manufacturer a lot, to make the product variety, specifications complex, the classification methods are also different. Although various magnetic separation machine has a different program difference, but according to the magnetic YangJiang degree, produce a magnetic field method, structure, choose different role don't, magnetic separation machine into a variety. Magnetic separator machine is use of various minerals than the coefficient of different magnetization, and by the magnetic mechanical force will magnetic mineral and the magnetic mineral separated machinery.

In the 1950 s in China only weak magnetic field magnetic separation machine belt type and tube type electromagnetic magnetic separation machine. Until 1965, just from Sweden Sarah company introduces the cavitation permanent magnet magnetic separation machine, and counterfeit, because it save electricity and magnetic induction high strength, simple structure, low cost, easy operation and maintenance, machine quality is light, cover an area of an area small, processing capacity, so fast in China in application, all replaced the electromagnetic magnetic separation machine. At present, our country magnetite concentrator use wet weak magnetic field intensity magnetic separation machine are permanent magnet tube type magnetic separation machine, using magnetic pulley and magnetic force to take off the cistern, also is the permanent magnet, realized the weak magnetic field of magnetic separation equipment and magnetized. By the 1980 s, permanent magnetic separation machine and get the cavitation fast development, not only the specifications varieties, and to the large-scale development, up to 1500 mm in diameter, tube has reached 4000 mm long, and on the structure and do improvement. At the same time, start to take new high performance materials of rare earth permanent magnet nd-fe-b magnetic materials, improve the magnetic induction strength, improve equipment performance, expanded the scope of application, in recent years, its application to obtain the further promotion, not only use it in manufacturing field magnetic separation machine, and successfully developed several strong magnetic field intensity magnetic separation machine.

The magnetic separation equipment level of technology has advanced international level, some already meets or exceeds international advanced level, in short in the world is advanced. Now in addition to the superconducting magnetic separation equipment, China's development, production of magnetic separation equipment has a leading position in the world.

In selecting a magnetic separation equipment, mainly is based on magnetic minerals and feed size to determine, such as strong magnetic minerals: grain size of 10-360 mm, choose magnetic pulley; Grain size of 6-0 mm, choose permanent magnet type magnetic separation machine; Weak magnetic minerals; Grain size of 7 to 14 mm, selection of roller of strong magnetic separation machine; Grain size in order to 5 mm, but according to ore properties choose ring type, roller type or disc strong magnetic separation machine; Grain size of 0.15 mm, can choose the high gradient magnetic separation machine.
