Ball Mill
Ball mill is the key equipment for grinding after materials are crushed at crushing plant.
Ball mill is an efficient crushing machine for grinding various materials into powder.
Ball mills are grinding machine which employ high carbon steel or special steel balls in ball mills. Ball mill crushes generally finer than those produced in Rod mill, and rod mills are well suited to handle finer feed and to control the smaller size of the product.
Tube type(Type T) Ball mill can grind materials to a fineness of minus 200mesh and is used as a secondary grinding mill after the Conical type(Type C) or Grate type(Type G) Ball mill.
Type T Ball mills are to produce a finished product from relatively fine feed in an open or closed circuit. These ball mills are equipped with thinner shell liners and employ smaller size grinding balls than that of Type C Ball mill.
Ball mill is widely applied in cement industry, chemical industry, new building materials, fire-resistant materials, fertilizer, porcelain and glass industry etc.
Ball Mill Working principle
Ball mill runs along the outside gear. Materials spirally and evenly enter the crushing chamber along the input hollow axis by input devices. Steel rods of different specifications are installed in the crushing chamber. When the frame rotates, centrifugal force is produced. At the same time, the steel rods are carried to some height and then fall to grind and strike the material. After grinded in the crushing chamber, the powder is discharges by output material board.
Ball Mill Features and Benefits
Ball mill is made up of feeding part, discharging part, gyre part, transmission part (reducer, small transmission gear, motor, and electrical controller) and so on.
Ball mill adopts a steel cast hollow axis and the linings can be replaced.
Ball mill adopts a forged rotary gear.
Ball mill has crushing chamber with wearable plates.
Ball mill runs steadily and efficiently.
