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.

Features

1. Strong adaptability;
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.

Repair method

Regularly check the components and connections for loose, damaged.

control cabinet should be the person responsible for operation and maintenance.

Every six months telemetry insulation resistance, identify problems in time.

Regular checks cabinet outside the cabinet, keep the meter display is clear and bright, the operating handle flexible action, contactors, each main electrical shock no dust.

when replacing the damaged components, replace the corresponding elements, can not arbitrarily increase the capacity.

when the grid voltage is less than 10% should be stopped.
