 Coal Mill

        The Application and Usage Range: 

    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.
Main Technical Parameters of Coal Mill:

 Ball Mill

Ball mill is the key equipment for re-crushing, it is widely used for dry or wet powder grinding operation of ore grinding before dressing ferro

us and non-ferrous metal, raw material or finished product of cement, chemical industry, novel construction material, refractory material, etc.   The machine is composed by feeding part, discharging part, turning part and driving part (reducer, small driving gear, electric motor and electric control).The quill shaft adopts cast steel part and the liner is detachable. The turning gearwheel adopts casting hobbing process and the drum is equipped with wear-resistant liner, which has good wear-resistance. The machine is with stable and reliable working condition.
Moreover, according to different materials and discharging methods, there are dry ball mills and wet ball mills for choice. our company owns the leading technology and rich practical experience, and we can offer 360 º service, and leave you from any worry.

General 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.

Dry or wet ball mill will be optional according to material and ore-discharging mode.
