ball mill for grinding the ore
MAIN FUNCTION of Ball Mill
Ball Mill is widely used in mining, building materials and chemistry industries. According to the milling way, the Ball Mill can be divided into dry and wet types. According to ways of discharge, the Ball Mill can be divided into lattice and overflow types or center-discharge and side-discharge types. In accordance with the different kinds of support, it can be divided into Bearing MiII and Bushing MiII. In accordance with the different kinds of transmission, it can be divided into edge and center types. The mills with the diameter above 3m allocate jacking devices for easy maintenance. So the dynamical pressure bearing and the static pressure bearing can operate stable. The low speed transmission is convenient for maintenance and starting. And the oil mist spray lubrication device ensures the reliable lubricating of big and small gears. Generally, the main motor of the large mill is high pressure asynchronous motor or synchronous motor. So customers should indicate the motor type in order.
Work Principle and Structure of Ball Mill:
Materials spirally and evenly go into the first cabin of the grinding machine through the feeding hollow shaft from the feeding device, and inside the first cabin, there are ladder lining boards or ripple lining board in which there are many steel balls with different specifications. The cylinder rotates and produces eccentric force to bring the steel balls to a certain height, and then the steel balls fall down to impact and grind the materials. After being coarsely ground in the first cabin, the materials will go through the single-layer partition board and into the secondary cabin in which there are flat lining board, and in the lining board there are steel balls to further grind the materials. Finally the powdery materials will be discharged from the discharging grating bar to complete the powder grinding process.
