Coal mill is major equipment of cement plant and used for drying and grinding coal. The equipment is mainly consisted of feed device, main bearings, rotating parts, drive device, selling device, high-voltage start-up device and lubrication system. The raw material is fed into mill by feeding equipment. The hot wind enters into the mill by inlet end. As the mill cylinder rotates, the coal and hot air exchange heat in the mill. The coal is crushed and grinded in the mill. When the coal is being grinded, the powder is brought out of the mill by the hot air going through the mill. The products have got the international quality certification of ISO9001: 2000 and the European CE certification. The coal mill we make is with reasonable structure, high grinding efficiency and is the ideal equipment for coal processing.



Working principle:
This machine is a skeleton pattern ball mill with horizontal cylindrical turning gear, driving by outer gear and two hoppers. The material goes to the first hopper after the spiraling by the quill shaft from the feeding equipment. The hopper has ladder sheathing or corrugated sheathing with steel balls inside, which will fall under the effect of centrifugal force by barrel turning to ram hard and grind material. After the kibbling in the first hopper, by monolayer partition panel, the material will enter the second hopper, which has plane scale board with steel ball inside to grind material. The powder material will be discharged from the grid plate to finish the grinding.

Ball Mill is made up of feeding part, discharging part, gyre part, transmission part, (decelerator, small transmission gear, generator, electrical control) and so on. The hollow axis adopts the cast steel and the lining can replace , the rotating big gear processes in the way of casting rolling gear. The barrel body is wearable well and bears wearable scale board. This machine runs steadily and works reliably.
 
Structure of Ball Mill
Ball mill is mainly composed of feeding part, discharging part, rotating part, transmission part (reducer, pinion, electric motor and electric control) and so on. Its hollow shaft is made of cast steel and inner lining is detachable and can be replaced. The rotating big gear is processed by casting hobbing machine. The inside of the cylinder is equipped with wear-resistant liners. The machine runs steadily and reliably. The main body of ball mill includes cylinder equipped with wear-resistant liners, bearing which supports the cylinder and maintains the cylinder's rotation, the drive part such as motor, gears, pulleys, V-belt, etc.
