Ball Mill  is an efficient tool for grinding many materials into fine powder. Ball Mill is used to grind many kinds of mine and other materials, or to select the mine. It is widely used in building material, chemical industry, etc. There are two ways of grinding: the dry way and the wet way. It can be divided into tabular type and flowing type according to different expelling mine. To use the Ball Mill, the material to be ground is loaded into the Neoprene barrel that contains grinding media. As the barrel rotates, the material is crushed between the individual pieces of grinding media that mix and crush the product into fine powder over a period of several hours.
Quite simply, the longer the Ball Mill runs, the finer the powder will be. Ultimate particle size depends entirely on how hard the material you’re grinding is, and the time how long the Ball Mill runs. Our Ball Mills have been used to grind glass, powder food products, create custom varnishes, make ceramic glaze, powder various chemicals, and make Black Powder.

how the ball mill works

1、A preface

Since in 1880 in industrial production ceramic grinding materials used since the ball more than 100 years history, despite a few advanced countries due to material technology development and only used in ceramic production only plays the ball mill ingredients (mixed), but most of the countries in ceramic production is widely used for grinding mill with mixed casting glaze ceramic raw materials, and paints. However, the efficiency of the ceramic production of ball mill is lower — about 1 %, so that a large amount of energy consumption. According to statistics, ceramic production in about 40 percent of the energy consumption in the ball grinding process. The ball mill process of material of particle shape and size distribution, the fineness, physical and chemical properties, production efficiency has important influence, this paper will be of ball mill process of related problems were discussed. The superficial

2 、the crushing mechanism of materials

Material in the ball mill process is shattered due to its body and abrasive abrasive results. However, the grinding process is extremely complex. If a single particles as research object, the ball mill process it may repeatedly by grinding compressive stress, which exists in the role of the particles on the surface of a new generation of inherent or expansion crack, and lead to its broken or plastic deformation. When the particles are constantly shattered. A certain level of new particles can be further ground, because the new particles on the surface of the crack, and appear a certain minimum fracture risk of crack stress reduced ACTS. When breaking process continues, the final for crushing stress could increase to make granules of plastic deformation degree. Now, with the plastic deformation, particle size is the will. Thus, when the materials are a grinding size limit. For raw materials, quartz can be ground for 1 micron in size limit, and as the extremum, limestone for 3 ~ 5 micron. That is, when the grinding materials into the scope of ultra-fine grinding mill, the effect was more difficult. In most of the grinding system has a real grind limit, this limit the main on grinding particles produced products, and the tendency to accumulate accumulate and broken up between the physical balance. Therefore, a long ball grinding extended time is meaningless, only leads to increased energy, because the meticulous grain can effectively storage needed to crack expansion of elastic energy.

The actual grinding process than the above discussion, the situation is much more complex particle surface crack expanding and new crack appear because each particle interaction among cracks, the sub-tissue particles interact with the wall, the function, the secondary role between particles and the effect with abrasive particles, particle physics and chemistry of the smell of particles and abrasive environments and aggravate, particle breaking. But, for the recognition of the essence of the visual sense or only on the basis of reasoning.

Vertical roller mill has many different forms, but it works basically the same. All of these forms of machine comes with roller (or the equivalent of roller grinding parts), and roller along the track of the disc at the level of circular movement imposed by external grinding roller in the vertical pressure on the disc on the material being the joint action of compression and shear, and to crush.
Material grinding process: motor through reducer rotating drive disc, the material falls from the mill under the central entrance and exit, under the action of centrifugal force to the disc edge by the roller to move and the crushing, grinding out lap after the material was speed up the flow to and vertical mill with one of the separator, after the meal by the separator back to the mill, the re-grinding; powder while grinding out with air, dust collection equipment in the system to collect down, that is, products . Established through the mill in the pneumatic conveying of materials, a larger air flow rate, which can use waste heat of gas, at the same time dry grinding operations.

Vertical Roller Mill Principle:
Used in cement grinding production grinding parts of its various forms, there is a cylinder, cone type, ball type, etc., and roller surface is also flat, curved, convex round noodles. Applied to the grinding roller to roller grinding along the track bed in close contact with the material strength of a spring pressure, hydraulic, etc..

How Vertical Roller Mill Works:
It has two pairs of grinding rollers, each pair of roller composed of two narrow rollers, mounted on the same axis and can rotate at different speeds. There are two circular disc slot, and roller to the tire shape, work pressure in the tank. Disc roller and the relative sliding velocity between small and roller can swing, even if the roller sleeve and the disc after the liner wear can guarantee a good abrasive, will not affect the grinding effect. Roller symmetrical structure, one side can be upside down after use and wear.
Material grinding process: hydraulic pneumatic roller device through the pressure applied to the material on the crushing of materials, the materials have been moved to crush the edge of disc, from the disc around the nozzle from the exhaust air to improve these materials to Separator.Meal to separate returns after a concentrated mill, fine powder was collected in the precipitator unloading. In the gas flow is small, the meal can not be increased to enhance air flow, they would fall through the nozzle discharged outside the mill, bucket elevator to be transported to the feeder of vertical roller mill, and was re-grinding mill feed people. This cycle features of the way there:
① ring by adjusting the air valve, can change the product fineness can Shide mill bed load material uniformity and stability, improving the grinding efficiency;
② coarse particles in the external circulation, helps reduce Fan power consumption and overall system power
