Ball Mill
A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints. Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles and stainless steel balls. An internal cascading effect reduces the material to a fine powder. Industrial ball mills can operate continuously, fed at one end and discharged at the other end. Large to medium-sized ball mills are mechanically rotated on their axis, but small ball mills normally consist of a cylindrical capped container that sits on two drive shafts (pulleys and belts are used to transmit rotary motion). A rock tumbler functions on the same principle. Ball mills are also used in pyrotechnics and the manufacture of black powder, but cannot be used in the preparation of some pyrotechnic mixtures such as flash powder because of their sensitivity to impact. High-quality ball mills are potentially expensive and can grind mixture particles to as small as 0.0001 mm, enormously increasing surface area and reaction rates.
Ball mills are generally used to grind material many kinds of mine and other materials, and the ball mill are used to select the mine. Ball mill is an efficient tool for grinding many materials into fine powder. Ball mill is widely used in building material, chemical industry, etc. There are two ways of grinding: the dry way and the wet way. Ball mill can be divided into tabular type and flowing type according to different expelling mine. This ball mill can be used for polishing, this ball mill can be used for crushing, this ball mill can be used for grinding, and mixing of various types of products. Iron particles, the ball mill are separated using magnetic separator ,the ball mill contain form of few sand particles due to rusted material. The ball mill has many features :ball mill is easy to be operated. Ball mill is to be used in many field .The longer the ball mill runs, the finer the powder will be..
Working principle of ball mill:
The ball mill is a horizontal rotating device transmitted by the outer gear. The materials are transferred to the grinding chamber through the quill shaft uniformly. There are ladder liner and ripple liner and different specifications of steel balls in the chamber. The centrifugal force caused by rotation of barrel brings the steel balls to a certain height and impact and grind the materials. The ground materials are discharged through the discharging board thus the grinding process is finished.
Ball Mill structural characteristics:
This machine is composed by the feeding department ,the Department of the Ministry of material, Rotary Department, the Department of transmission (reducer, a small gear, electrical, electronic control), and other key components. Hollow shaft uses steel casting, lining can be exchanged. Rotary gear has casting hobbing, The body is inlaid with wear-resistant cylinder liner, which has good wear resistance. The machine is smooth-running and reliable.
