Cement mill cement grinding optimisation fote machinery. cement mill is one of the major cement equipments and is the key equipment for grinding.
Grate discharge ball mill this type of mill usually works withigh circulating load and thus produces very little extreme fines. the specific power consumption is therefore less than for an overflow mill.rate discharge mill will also have 1525 higher capacity per volume unit as compared with an overflow mill.
In cement production process, about 26 of the total electrical power is used in grinding the raw materials. during grinding process, the energy obtained from the rotary burner is consumed. in this study, the first and second law analysis ofaw mill is performed and certain measures are implemented in an existing raw mill inement factory.
In other words, tdp is the saturation temperature of water corresponding to the vapor pressure tdp tsat pv 8.0 cement mill specific power consumptionement mill is usually limited by drive power so that any reduction in kwht translates in to increased production capacity as well aseduced unit power cost.
In the last decade vertical mills have taken an increasing share of the cement milling market, not least because the specific power consumption of vertical mills is about 30 less than that of ball mills and for finely ground cement less still. the vertical mill hasroven track record in grinding blastfurnace slag, where it has the additional advantage of beinguch more effective drier.
In this study, certain measures are implemented in an existing raw mill inement factory and the specific energy consumption of the unit is calculated.
It is generally accepted that practical mill power pm isunction of mill capacity and diameter, i.e.,pill constant mill diameterhere.3 to 0.5. it is evident that mill power isunction of the height at which the media is lifted and the density of the media, i.e., pm ld 2.5 wheresroportionality constant.
Mill used, i.e. ball mill or vertical roller mill. typically, the motor of the ball mill consumes about 14 15 kwh ton of raw mix whereas the vrm motor uses kwh ton. on an overall basis, vrm consumes about 20 lower specific energy than conventional closed circuit ball mills and is.
