Ball mill uses steel ball as grinding medium.Because the steel ball is in point contact with the ore, the grinding products are of high fineness, and the particle size of the products is relatively fine, which is prone to over grinding, so ball mill is not suitable for the re-selection production line in ore dressing.
Cement clinker is usually ground using a ball mill.This is essentially a large rotating drum containing grinding media - normally steel balls.As the drum rotates, the motion of the balls crushes the clinker.The drum rotates approximately once every couple of seconds.The drum is generally divided into two or three chambers, with different size grinding media.As the clinker particles are ground down, smaller media are more efficient at reducing the particle size still further.
Metering and airlock device to feed clinker and other materials into the ball mill or vertical roller mill.
To coarse grinding of materials in the first position after the board by the single compartment into the second warehouse, the warehouse lined with flat lining, steel ball inside, the material to further grinding.Powder discharged through the discharge grate plate to complete the grinding operation.Structural characteristics of ball mill from the feeding part, discharging department, rotary department, transmission division (reducer, small transmission gear, motors, electrical control) and other major components.Hollow shaft with steel casting, lining replaceable, slewing gear hobbing by casting process, the body inlaid cylinder liner wear, has good wear resistance.
Ball mill is the key equipment for grinding crushed materials, which can be used for grinding limestone, dolomite, calcite and other ores.
