Ball mill is a type of ore milling machine used to grind materials into an extremely fine powder, mainly used in the mineral ore processing industry.Ball mill could grind various ores and other materials either wet or dry, depending on requirements.It consists of a large cylinder which slowly rotates around a horizontal axis.Get Price
The supervisory expert control for ball mill grinding circuits is a scada system, which consists three levels, the first level instrumentations and actuators, including particle size analyzer, flow meters, valves, etc, level 2 regulating system composed by programmable logic controllers plcs, and level 3 supervisory system.
Ball milling ball milling is a grinding technique that uses media to effectively break down pigment agglomerates and aggregates to their primary particles.Using a rotor or disc impeller to create collisions of the grinding media, the impact and force created by.

Multi feeder device for ball mill equipment the ball mill is an excellent material grinding equipment, widely used in mining, stone factory, chemical laboratory, etc., can be divided into energy-saving ball mill, intermittent ball mill, cone ball mill, ball mill, rod mill and other types of explosion-proof.There are many kinds of feeder for ball mill, such as pipe feed, drum feeder, screw.
2 shows a flow sheet where the rod mill is in open circuit and the ball mill is in closed circuit with a classifier.This is a normal set-up as the primary function of a rod mill is to provide a uniform sized feed to the ball mill.3 shows that the rod mill product is classified and a more uniform feed.
Feed chute it is normally a fabricated steel pipe of adequate diameter and provided with inside liner.Feed sleeve it is generally fabricated with mild steel.Sometimes cast steel feed sleeves are also used.Inside of the sleeve has forwarding spirals.Efficient sealing arrangements are provided at the junction of the feed chute and feed sleeve to prevent leakage of slurry in wet grinding.
When the main bearing of the ball mill works, heat is continuously transferred to the bearing from the hot material and hot gas drying and grinding inside the mill, and the contact surface between the bearing journal and the bushing generates heat due to friction.If not eliminated, the accumulated heat will make the bearing temperature rise to destroy the lubrication of the ball mill.
Fresh feed and separator grits were combined and fed to the mill.The ball mill has an inside diameter inside liners of 0.Its length can be varied by combining different tube shells with a length of 25 or 50 cm in the range of 1.3 shows the mill.The material, which is discharged pneumatically by the mill ventilation.
