Introduction:
A ball mill is a type of grinder used to grind materials into extremely fine powder for use in mineral dressing processes, paints, pyrotechnics, ceramics and selective laser sintering.
Ball mill machine widely used in Building materials industry, processing industry, power industry, chemical industry and metallurgy industries etc.
Principle:
A ball mill consists of a hollow cylindrical shell rotating about its axis. The axis of the shell may be either horizontal or at a small angle to the horizontal. it is partially filled with balls. The grinding media is the balls, which may be made of steel (chrome steel), stainless steel or rubber. The inner surface of the cylindrical shell is usually lined with an abrasion-resistant material such as manganese steel or rubber. Less wear takes place in rubber lined mills, such as the Sepro tyre drive Grinding Mill. The length of the mill is approximately equal to its diameter.
Operation:
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 ones 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 5 nm, enormously increasing surface area and reaction rates. The grinding works on the principle of critical speed. The critical speed can be understood as that speed after which the steel balls (which are responsible for the grinding of particles) start rotating along the direction of the cylindrical device; thus causing no further grinding.
Delivery Time:
Because ball mill belongs to large industrial equipment, Different ball mill have different production cycle, The shipment will inform the customer in the process of business negotiation.
Our two production base of mining machinery has about 700 sets of various production equipments. Annual production capacity is 40,000 tons of mechanical products. All these make us have the ability to produce larger and special larger equipments. Our main products including: ball mill, rotary kiln, jaw crusher, cone crusher, etc. and all kinds of spare parts.
Our manufacturing base of filter equipment mainly produce full automatic or semi-automatic membrane filter press, recessed filter press, belt filter press, centrifuge, etc. All these products are widely used in mining, metallurgy, petroleum, chemical, medicine, textile, printing and dyeing, paper making, food, alcohol, inorganic salt, coal washing, and waste water processing industry.
