the power consumption of the cement grinding accounts for about 40% of the total power consumption of the cement production process. therefore, the selection of a reasonable cement grinding system plays a key role in energy saving and consumption reduction of cement plants. nowadays, the cement grinding system has developed from the previous single ball mill system to ball mill roller press system and
reduce steel consumption. when grinding cement, the ball mill has a yield of and the grinding system of the roller press has a yield of 0.t, so it can meet the requirements of white cement. low noise. the ball mill noise is above 110 db, while the roller press is about db.
maintenance work. To allow the grinding of differ-ent materials and finenesses, a variable-speed motor or a speed-change gear unit adapts the grinding speed to the required product characteristics and product fineness. housing the housing is fitted with spe-cial seals to prevent the inleak-age of false air. easy-to-open doors facilitate maintenance of the mill.
the open-circuit grinding system of the ball mill is shown as follows: materials mixed according to a certain proportion will be directly stored in the steel silo as finished cement products after being ground by the ball mill. the open-circuit grinding system has the characteristics of simple production process, less equipment, simple maintenance, small investment,
