1) Ball mill is from the cylinder, and out of the hollow shaft and the grinding material and other parts of the level of composition, cylinder for long cylinder, cylinder with grinding, cylinder of steel plate, with steel liner and cylinder fixed, grinding usually steel spheres, according to a certain percentage of different diameters and loaded barrel, grinding steel segment can also be used. Be selected according to the particle size of the abrasive material, the material from the mill feed end of the hollow shaft into the cylinder body, when the ball rotates the cylinder when grinding due to inertia and centrifugal force, the role of friction, so that it is attached to the cylinder liner was taken away by the barrel, when the time was taken to a certain height, because of its own gravity has been thrown down, falling like a projectile, like grinding the material to crush the cylinder body.
2) Material from the feeder evenly into the mill first warehouse into the compound by the air shaft spiral, the warehouse has ladder liner or corrugated liner, built with a variety of ball, rotating cylinder produces centrifugal force to the ball a certain after the height of the fall, have severe impact on the material and abrasive. The material in the first position coarse, the single-compartment plate into the second warehouse, the warehouse lined with flat lining, the steel ball, the material to further grinding. Powder is discharged through the discharge grate plate to complete the grinding operation.
3) During the rotation of the cylinder, the grinding media have dropped the phenomenon, in the process, to fall to abrasive materials, in order to effectively use abrasive effect on the material particle size larger general purpose Ground twenty when the mill cylinder body with a separate compartment for Sec board, namely a two-compartment, the material into the first position when the ball was crushed, the material into the second position when the steel section of the material for grinding, grinding the material passing from the discharge end of the hollow discharge axis of the feed materials for grinding small particles, such as when sand II slag, coarse ash, mill shell not to set partitions, a single-chamber tube mill, grinding steel sections can.
4) Raw materials through the hollow journal to carry out ground into a hollow cylinder, the cylinder built with various diameters of grinding media (balls, steel bars or gravel, etc.). When the drum about a horizontal axis of rotation at a certain speed, mounted in the barrel of the medium and materials under the action of centrifugal force and frictional force, as the cylinder reaches a certain height, is greater than when the centrifugal force of its own gravity, then from the cylinder falling or rolling down the inner wall of the projectile, as a result of the impact and crushed ore. While during the rotation of the mill, grinding media sliding movement between each other to produce the raw material also the grinding effect. After grinding the material discharged through the hollow journal.
