A coal mill is used to grind and dry raw coal into fine powder, which is then burned to generate heat in the boiler to produce steam for power generation. How does a coal ball mill work?
BALL TUBE MILL The Ball Tube Mill is basically horizontal cylindrical tube rotating at low speed on its axis, whose length is slightly more to its diameter. The inside of the Cylinder shell is fitted with heavy cast liners and is filled with cast or forged balls for grinding, to approximately 1/3 of the diameter. Advantages of Ball tube mills include high availability, low maintenance

Output = Input x Efficiency In a ball mill circuit, the "output" can be defined as the production rate of fines of the circuit. As for any output, ball mill circuit output is a function of both its inputs and efficiencies. There are two "inputs" to a ball mill circuit: the ore fed to the circuit and the power delivered by the grinding mill.
