Coal Mill


Coal mill is the key equipment for grinding after the crushing process, which is widely used in the manufacture industries, such as cement, silicate, new building material, refractory material, fertilizer, ferrous metal, nonferrous metal and glass ceramics and can be used for the dry and wet grinding for all kinds of ores and other grind-able materials.

 

Coal Mill Application:

Coal mill is the key equipment for grinding after the crushing process, which is widely used in the manufacture industries, such as cement, silicate, new building material, refractory material, fertilizer, ferrous metal, nonferrous metal and glass ceramics and can be used for the dry and wet grinding for all kinds of ores and other grind-able materials.

Coal Mill Working pinciple:

The machine is composed by feeding part, discharging part, turning part and driving part (reducer, small driving gear, electric motor and electric control).Coal Mill is a skeleton pattern ball mill with horizontal cylindrical turning gear,drive by outer gear and two hopers.The material goes to the first hopper after the spiraling by the quil shaft fro m the feeding equiment,The hopper has ladder sheathing or corrugated sheathing with steel ball s 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 hooper,by monolayer partition panel,the material will enter the second hooper,which has plane scale board with steel ball inside to grind material.The powder material will be discharge from the grid plate to finish the grinding.
