Ball Mill Grinding Technology

Some knowledge about ball mill

Ball mill is the material after being crusher, and then to smash the key equipment. One high-fine grinding mill machinery is widely used in industrial production, which has many types of ball mill is widely used in cement, silicate products, new building materials, refractory materials, fertilizer, ferrous and nonferrous metal and glass ceramics and other production industries can be divided into dry and wet grinding methods. According to different ways of discharge can be divided into tabular type and flowing type two. Short cylinder shape can be divided according to mill, ball mill barreled, conical tube mill and mill four.

Ball Mill Features

The machine consists of feeding part, discharging part, turning part and driving part (reducer, small transmission gear, motors, electrical control) and other major components. Hollow shaft with steel, lined with removable, rotary gear hobbing by casting, the body inlaid cylinder liner wear, has good abrasion resistance. The machine running smoothly, reliable work.

Principle mill

Ball Mill is from the cylinder, and out of the hollow shaft and the grinding material and some level of composition, as long cylinder barrel, cylinder with grinding, cylinder of steel plate, with steel liner and cylinder fixed, grinding usually steel balls, and then loaded with different diameters and a certain percentage of the barrel, grinding steel section can also be used.

Be selected according to the granularity of the grinding, the material from the mill feed end of the hollow shaft into the cylinder body, cylinder rotation when the mill when grinding due to inertia and centrifugal force, the role of friction, making it attached to the cylinder liner cylinder was taken away when it was brought to a certain height, due to its own gravity has been thrown down, falling like a projectile, like grinding the material to the cylinder body crushed.

Optional Skills

A guarantee of the mill production capacity: the choice of grinding equipment, to ensure the conditions to achieve the required grinding fineness, the completion of the required output.

Production capacity should be higher than some of the design; design changes to be considered ore hardness and fineness, usually deep ore deposits in hard or thinning should be chosen so that the mill can adapt, while ensuring that the initial smooth operation.

Grinding tests must be done; no actual data in the design as a basis, the test must be requested for grinding, especially for large concentrator, basic data should be obtained mill select computing and scaling.
