During the grinding process the operator of the ball mill is responsible for the equipment and production ore it is necessary to check and adjust the ball mill and its equipment as well as each link of the grinding process to eliminate faults in time prevent accidents and ensure the normal grinding process first the ball mill rotary body inspection.

Gratedischarge type the gratedischarge type of ball mill has a grate at the outlet of the shell and causes less excessive grinding compared to the overflow type therefore generally it is best suited to grind materials up to the particle sizes ranging from 60 to 100 mesh.

If a ball mill uses little or no water during grinding it is a dry mill if a ball mill uses water during grinding it is a wet mill a typical ball mill will have a drum length that is 1 or 15 times the drum diameter ball mills with a drum length to diameter ratio greater than 15 are referred to as tube mills.

It is assumed that the ore is continuously discharged from the feeding port to the discharge port the ball milling time calculated under this ideal state is the minimum grinding time the filling rate of the ball mill is 40 if the slurry level reaches 50 filling rate the slurry will flow out automatically.
