- This coal dust grinding mill has a big processing capacity, the advantages of continuous operation is obvious .
- Cylinder liner and grinding media can use a variety of materials, corrosion resistance is strong, and use is wide.
- This coal dust grinding mill is of convenient installation and commissioning , easy to operate.
- This coal dust grinding mill productivity is high, the cost of use is low.
3 Working principle of coal dust grinding mill
This machine is a horizontal type cylinder rotary device and outside the cylinder there is drive gear which drives the cylinder to rotate during the working process. 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.
