Ball Mill

Feeding Granularity: ≤20-≤25mm

Applicable Range: Cement, silicate product, new building material, refractory material, fertilizer, black and non-ferrous metal ore dressing and glass ceramics production industry etc.

Introduction

Ball mill machine is the key equipment for recrushing the materials after they are primarily crushed. It is widely used for the dry type or wet type grinding of all kinds of ores and other grindable materials in cement, silicate product, new building material, refractory, fertilizer, black and non-ferrous metals and glass ceramic industry. The ore grinding methods of ball mill include dry type and wet type.

Ball mill machine is mainly composed of feeding part, discharging part, rotary part and driving part which includes reducer, small drive gear, electrical machine and electronic control. The hollow shaft uses steel casting, the inner lining can be dismantled and changed, and the rotary rack wheel uses casting gear hobbing and inside the cylinder there is wear-resisting lining board which has fine abrasion performance. This machine has stable operation and reliable performance.

Working Principle

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 will 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.
