Cement Mill Increasing Quality of Final Cement

Cement mill is usually ground using a 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.

The drum is generally divided into two or three chambers, with different size grinding media. As the clinker particles are ground down, smaller media are more efficient at reducing the particle size still further. By determination of the particle size distribution, electric energy reduction potentials can be revealed. The main obstacles are the complex interdependences between the mentioned parameters. The modeling and simulation of ball mills has proven to be effective methods for obtaining further understanding. Besides providing savings in electrical energy this measure can reduce the cost induced by wear.

The shell lining in the second compartment or in one compartment finish-grinding mill has special classifiying plate lining and a charge of smaller balls for fine grinding. It is designed to obtain efficient fine grinding. For fine grinding, the charge consist of small balls, which ensure the best possible grinding efficiency without obstructing the material flow through the ball charge. Special designed diaphagm between the grinding compartments effectively screens the material passing from the coarse to the fine grinding compartment. Our strength lies in our comprehensive technologies including the feasibility study, designing, manufacturing, procurement, construction, test-running, running, operation & maintenance, renovation of cement plants as well as manufacturing machinery for cement plants.

Grinding Aids are organic compounds that are usually added to clinker directly into the cement mill. Recommended for use in the cement industry as performance enhancer to reduce energy consumption, increase the efficiency of grinding, improve separation and cement flow characteristics. The main result of Grinding Aids increase of production rate in cement mill and quality of final cement.
