MQ Series Ball Mill

Ball mill is the most widely used kind of grinding equipment. Zenith Ball mills are widely used in various types of ores’ benefication, electricity, cement and chemical industries. With high comminution ratio,it can carry out dry or wet pulverizing and can meet demand for sustainable large-scale production. The most widely used in the production of a variety of ores are wet overflow ball mill and wet grate ball mill.

Features

1.Traditional sliding bearings are replaced by double row roller bearings in small and medium size ball mills to reduce energy consuming

2.Large ball mills adopt pitot pressure or hydrostatic bearings.

3.Air clutch system for starting the motor safely

4.Alternative synchronous or asynchronous motor

5.Low speed driving unit with Lifting device, convenient for maintenance.

6.New Endurable wearing parts to increase service life of vulnerable parts.

7.Alternative PLC automatic control system Optional Accessories ( drum sieve, Hydraulic wrench mobile feeding settings)

Coal mill

Coal mill is an important auxiliary equipment for coal-powder furnace, it has three methods to crush the coal lump and grind them into powder,it is crushing, impacting and grinding.

Air swept coal mill is the main equipment in cement plant for both drying and grinding of the powders. Compared with the ordinary ball mill, it has advantages of higher capacity, more convenient operation, safer usage, and more reliable performance.

Coal mill is used to grind, pulverize and dry coal before the coal is transmitted the boiler. The coal is feed into the coal mill via a inlet pipe so that the roller coal mill such as ball mill or vertical mill can pulverize the coal into particles.

Raw Mill

Raw mill is mainly used in grinding raw materials and end products in cement plant. It is also suitable for various ores and other materials metallurgy, mine, chemical and construction. Besides, it has two forms of milling, one is an open form, and the other is a recycle close form equipped with powder concentrator. It is widely applied in many industries and has convenient operation.

Cement Mill

A cement mill is the equipment that used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement. Most cement is currently ground in ball mills.

Cement clinker is usually ground using a cement 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.

Grinding systems are either ‘open circuit’ or ‘closed circuit’. In an open circuit system, the feed rate of incoming clinker is adjusted to achieve the desired fineness of the product. In a closed circuit system, coarse particles are separated from the finer product and returned for further grinding.

This cement ball mill is mainly used in grinding cement finished products and raw materials and also suited to metallurgical, chemical, electricity etc. and other industrial mining enterprises. It could also be used to grind various ore materials and materials that is grindability.

2. Continuous produce;

3. Broken rate large;

4. Easy to adjust the product grinding fineness etc;

5. It can not only produce with wet type, but also grind and dry simultaneously.

Rod Mill

Rod mills are very similar to ball mills, except they use long rods for grinding media. The rods grind the ore by tumbling within the the mill. To prevent the conditions leading to rod charge tangling, the length to diameter ratio is maintained at 1.4 to 1.6. Rod mills accept feed up to about 50 mm (2 in.) and produce a product in the size range of 3000 to 270 mm (4 to 35 mesh).

Rod-mill

Rod mill is widely applied in metal and nonmetal mine, water conservancy, glass and construction materials industries, mainly suitable for grinding various ores and rocks and artificial sand-making.

Features

1. Easy and safe operation.

2. Stable performance.

3. Even product size.

4. Low energy consumption.

5. Low invest,high return.
