In recent years, the grinding mill used in more and more fields, for example, non-metallic minerals, chemical raw materials, advanced ceramics raw materials, processing precision abrasive etc., can be used in ultra fine mill  for processing, but the face of ultrafine mill type variety, how to choose it, standing in the user perspective simple analysis on how to choose the appropriate ultrafine mill machine.

At present, the size of the size of the more than 100 mill manufacturers, facing a large number of ultrafine mill manufacturers, how to choose the customer? This is a problem for users. The ultrafine grinding machine is widely used in the grinding of metallurgical, building materials, chemical, mine and other fields.

The expansion of the application scope of the ultrafine mill has brought the gospel to the users, and it also brings difficulties to the users. Because of the expansion of the scope of application, a large number of manufacturers have come to produce ultrafine mills and other grinding machines, which have laid the obstacles for the user's choice. After years of experience, Shi bang machine has brought the gospel to numerous users. According to the requirements of customers, we summed up the following items, attacking customers' reference.

When choosing the ultrafine grinder, we should pay attention to the following points: whether the machine meets the requirement of product fineness, which is the basic requirement; secondly, whether to meet the requirements of output or scale. Mainly considering the production capacity of single equipment, in order to meet the premise of production, the number of equipment table is as few as possible.

According to the point of view of saving, the unit energy consumption of the ultrafine mill is also an indicator of choice. The lower the unit energy consumption, the lower the production cost of the product, the greater the income. In the process of use, the wear and tear of the equipment is also an important parameter. The wear and tear of equipment will increase the service life of the bottom hole equipment, increase the cost of equipment input, and affect the quality of the products. When the equipment is selected, the strength, material and abrasion resistance of the worn parts should be compared.

In the selection of ultrafine mill, remember, good machine, its equipment matching performance is generally excellent. Moreover, the user should choose the simple equipment of the process system, save many unnecessary links to our production, and save the cost of production. It is also necessary to choose equipment with good performance and simple process as much as possible, which has brought guarantee to production.

Now, environmental protection is more and more important, so environmental indicators can become long producing many machinery industry standard, so, as a user, we should choose the dust emission, noise, environmental protection and labor safety and health standards of the equipment, the response of policy.

Company development and production of ultrafine mill is a kind of vertical milling machine, it can be used for a variety of ore materials and the production of flour, Ultrafine Mill application field is very wide, the following information for more than two of the product for your brief introduction, I hope for your help to the production of flour with a certain.

Ultrafine grinding mill is a product of vertical mill. When it is used in ore material pulverizing, it uses the principle of material disc grinding, that is, ore material is transported to the material tray of machine, and then it is rolled by the grinding roller on the material pan to achieve material grinding.

Ultrafine mill is a machine developed in the mill on the basis of the research, its purpose is to expand the scope of product fineness of vertical milling machine series products, the original 80 mesh to 400 mesh fineness range of 80 to 650, this is because the company developed legislation the original grinding fineness of 80 mesh to 400 mesh, the machine developed after the vertical mill in the range of fineness 400 mesh to 650 mesh, and therefore expand the machine finished feed range.

Ultrafine mill can grind mineral species more, generally if the ore Mohs hardness of less than five, the mineral density below 3.2, minerals belong to non flammable and explosive products, customers need to get the finished material fineness in finished product fineness in the scope of this machine, most can use this product to the production of flour, and can these ore materials are as follows: limestone, dolomite, calcite, barite, talc etc..

Because ultrafine grinding powder grinding fineness can be relatively high, in 400 to 650, but the relatively narrow range of fineness of slag powder, so finished industrial applications are not particularly like in metallurgical industry, non-metallic ore milling industry, this product has important applications.

After the ore ultrafine mill grinding, mainly used to produce raw materials for production or packing, such as limestone materials, after the product was obtained by grinding 600 or 400 mesh fineness of material, can be used as fireproof ceiling and floor brick production, can also be used in the manufacture of rubber and plastic etc..

We based on the in-depth study of traditional grinding mill, developed SCM ultrafine mill. This SCM Ultrafine Mill is building materials, mines, electric power and other industries of hard materials, micro fine grinding equipment, such as raw materials for limestone grinding cement manufacturing industry, sintering clinker with blending material powder into the finished cement, ore mine ore fine grinding in order to improve the grade of ore, coal power plants will be ground for full combustion.

The ultrafine mill, using the multipoint feeding, the innovative design of mill feed grinding and feeding, grinding, sieving into the discharge tube and the external aggregate, spiral feed back pipe and feed back device structure, the abrasion resistant material to grinding, grinding time, easy to wear the material for grinding, shorten the grinding time, the grinding process for grinding mill grinding sieving, its circulation, improve the mill performance and technical level, to simplify the process, reduce the equipment configuration, reduce the investment and energy saving purposes.

The technology principle of multi-point reclaiming for ultrafine grinder is that the shaft of the fine powder tube mill is set to 2 -4 grinding stores, and the material moves under the impact of the abrasive body in the cylinder body and the front end of the self tube body to the rear end. When the material is grinded by a warehouse, the fineness of a part of the material is reached to the finished product. In order to make this part of the material can be extracted, the invention is in between the tail warehouse superfine grinding machine machine each warehouse with a double chamber chamber separating device part is provided with a material extraction isolation device, diaphragm lifting plate, the circumferential direction of the tube body compartment parts set a uniform distribution of the material a radial hole, the outer side of the cylinder body hole welding material body with double flange shape, a lateral body material provided with a discharge hood, an air outlet is arranged at the top of the cover material, outlet and the external equipment dust suction pipe connection, after finished material bin before grinding after being extracted here. The finished product is collected through the external set of dust collector and sent to the finished product hoist, together with the finished finished product into the finished storage tank.

The percussive sand making machine is  used in most of the domestic projects, and its sand making machine effect is affected by many factors. Recently, it has been consulted by the users that the sand production of the machine is low and the economic benefit is not good. The effect of water content and feed amount of the broken material on the sand production of the percussive sand making machine is mainly analyzed.

1. When the water content of the broken material is controlled in a certain range, it can play an important role in the effect of dust removal, but it will lower the amount of sand production when the water content is high.

2. The effect of the water content of material on the quantity of sand production is as follows:
When the water content of the material is not more than 2%, the dust pollution is serious during the process of crushing, and the dust removal device must be adopted.

3. When the water content of the material is more than 5%, the rate of sand production is obviously reduced, and the output of the material decreases sharply with the increase of the water content of the material.

4. When the water content is up to 9%-11%, the rate of sand production is almost zero.

5. When water content is more than 11%, wet sand production should be used, but the amount of sand production is lower than that of dry process.

The effect of feed quantity on sand production of sand machine:
1. when the feed amount is small, the amount of sand production increases with the increase of feed quantity.
2. when the amount of feed is increased to a certain amount, the amount of sand production reaches the value.
3. when the amount of feed is more than a certain amount, the amount of sand production will be reduced. The reason is the large flow broken stone, the stone thrown most above the rotor flow in the stone is not playing on the anvil's sake.

In particle size, water content and crusher rotor at the same speed, feeding amount, then reduce the content of finished powder sand and modulus of sand particle size increases; when the moisture content of the material, stable material feeding, crushing machine rotor at the same speed, if the particle size increases, the content of stone powder the increase in particle size and modulus decreased; particle size, moisture content, feeding the same amount, rotor speed rise, increase the content of powder sand, particle size reduced modulus.

In the series of pulverizer products developed by the company, there is a series of common series, that is ultrafine mill. This Ultrafine Mill has an important role in the production of cement. With the rapid development of the domestic real estate, real estate and related downstream industries have been developing very fast, the industry, ore processing in cement production machinery manufacturing industry have made great development, and the development process in cement production industry, cannot do without the help of ultrafine mill.

Cement is necessary for building construction products, and is mainly sand, water mixing into concrete, cement in concrete production plays the main role is the binder, and the steel and concrete production is the main material for building construction, from this point we can see that an important role in the construction of cement built in.

Cement is a widely used product. In order to meet the demand for cement in the market, many customers are engaged in cement processing and production, so how is cement produced? Generally speaking, cement is the process of processing ore powder after firing. Mineral powder is an important material for cement production, so to produce cement, we first need to produce mineral powder.

There are many kinds of different kinds of ore powder, because it was obtained after grinding, ore is different, and in the production of cement powder needed is mostly obtained by limestone after grinding, grinding into powder or limestone, is a raw material for cement production.

Because in the cement production of limestone powder fineness requirements are not very high, so we used to ultrafine mill powder grinding is different from other milling equipment, we usually use ultrafine mill to grind limestone in cement production, because the vertical milling machine company development and production to grind limestone, limestone and the ground below 650 mesh the fineness, and customers through the finished material fineness regulation can accurately adjust the fineness of slag, limestone for specific processing, so as to meet the requirements of cement production, in order to serve the construction industry, so as to bring economic benefits to customers.

Ultrafine mill is the most commonly used equipment in cement production. It can not only be used as grinding material for limestone and other raw materials, but also can be used for the production of desulfurizer, so as to help the flue gas desulfurization of cement plant after burning, so as to achieve environmental protection production.

Raymond mill has high sales in the market, the quality of the Raymond mill can bring customer high yields and yield, efficiency, also can make Raymond mill factory of the brand, the so-called word-of-mouth effect. The application of Raymond powder mill is widely used, which is the grinding equipment chosen by many powder enterprises.

Raymond mill pressure is produced by hydraulic system, hydraulic system of hydraulic station and hydraulic cylinder, hydraulic cylinder attached to the accumulator, the grinding process on the hydraulic pressure vibration and buffer the role of mechanical load. When the pump station works, the hydraulic pressure can also be raised, and the grinding pressure should be basically equal to the grinding pressure, otherwise it will affect the normal operation of the grinding mill. The grinding roller is affected by the pressure of the roller and the drawing rod, which directly affects the output: the grinding pressure is large, the grinding effect is enhanced, and the output is high. Conversely, production is low. However, the grinding pressure should not be too large, otherwise, the main motor will be increased in accordance with the increase of the non-working, and the vibration of the pulverizer will be increased, and the lining board and other equipment of the grinding machine will be damaged. In the operation engineering, to maintain the grinding pressure in the setting range.

Raymond grinding out pattern in the material is due to Raymond mill powder weight and related parts in the hydraulic system formed by the interaction of tensioning force of milling force and the grinding pressure makes the material inside the Raymond mill to high speed, continuous mill, Raymond mill which can make the material being ruled out. However, the parts of the Raymond mill machine are very easy to wear, and if they are worn, it will cause less pressure and lower quality. At the same time, it will increase the cost, production and work efficiency will also decrease continuously. If without considering the related parts of wear condition, the hydraulic system tension force as a variable, in order to maintain the normal operation of the construction work, to increase the tensioning force liquid system, will raise Raymond mill milling force, improve the efficiency of Raymond mill work, increase the production of Raymond mill machine.
