Cement Mill Has A Wide Range Of Application

It could be used to grind various ore materials and materials that is grindability.

Features cement mill

 cement mill

It should be noted that grinding is the single largest consumer of energy within the raw material and cement clinker process circuit. In the cement manufacturing industry, limestone or dolomite raw materials require grinding twice before the final cement product can be packaged and sold. Initially, the process is a typical crushing and screening application. Rock is blasted from the quarry face, crushed and screened down to a 40mm to 20mm product before being placed through a mill. The milled raw material is then heated in a kiln to produce cement clinker which in turn requires grinding to produce a saleable cement product.

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.

Product advantages

  • Strong adaptability;
  • Continuous produce;
  • Broken rate large;
  • Easy to adjust the product grinding fineness etc;
  • It can not only produce with wet type, but also grind and dry simultaneously.

Repair method

  1. each bearing are using a No. 1 MOS2 grease or ZM - 2 sodium grease lubrication, roller bearing refueling once every two classes, the host bearing refueling once every four classes, blower bearings refueling once every month. Bearing temperature rise to a maximum of 70 degrees Celsius, was found to be breaking the bearing overheated bearings and bearing chamber cleaning accessories such as cleaning once.
  2. if the head of the rivet is worn impeller, the impeller body by pressing and welding with the welding of the hub, so that the wear of the head of the rivet back to the normal state.
  3. the rivet hole prone to fatigue cracks, the entire root available unused new electrode welding repair cracks, but at the center of symmetry axis impeller carried the rest of the crack at the welding electrode to stay in the area, and then a new welding repair cracks symmetrical rivet holes, as long as the rest of the electrodes when welding finished with symmetrical rivet repair the rest of the electrodes, welding up to ensure equal weight
