Introduction of Ball Mill

Application of the machine:
Ball mill is used to grind all kinds of mines and other materials and is widely used in mineral separation, building materials and chemical industry, etc and is divided into different types. According to different grinding method: dry grinding and wet grinding; according to the different materials-discharging method: grid type and overflow type. The ball mill is key equipment for the materials to be grinded after being crushed. It is widely used in producing industries such as cement, calcium silicate concrete, new-type building materials, and chemical fertilizer, ore dressing for black and non-ferrous metals, glass and ceramics for both dry and wet grinding purpose.

Structure:
The machine mainly consists of feeding department, barrel department, discharge department, transmission department (reducer, small transmission gear, electric motor and electric control), etc. Barrel welded with steel plate, using screw bolts to join the two ends and the sleeve shaft for input and output together, sustaining horizontally on two bearings. There are adjustable material-leading pipes in the sleeve shaft for input and output to pass. Tube inwall contains wear-resisting or batching welts and the tube cavity have certain grinding media (ball or rod) and raw materials.

Chief advantages:
The end for discharge has grid plates. It makes a feature of low liquid level for discharge to output the ore powder timely, less over crushed materials and high crushing capacity-10～15% higher than overflowing ball mill of the same specification.

Working principle:
The materials are transferred to the grinding chamber through the quill shaft uniformly. There are ladder liner and ripple liner and different specification of steel balls in the chamber. The centrifugal force caused by rotation of barrel brings the steel balls to a certain height and impact and grind the materials. The ground material is discharged through the discharging board thus the grinding process completes.
