Addition of grinding balls watch raw mill sec daily and add grinding balls in right timing →10 energy saving expected ball diameter shrinks as time passes due to erosive effect. this leads to gradual increase of raw mill sec. filling level of grinding balls is also important in grinding efficiency. optimum level of filling should be maintained.
As less grinding energy is used in producing a cement of a required fineness in an ok mill and the retention time in the mill is shorter the product will not be heated up as much as in a ball mill. this means that a lower degree of dehydration of the gypsum must be anticipated. this may not be a problem if the gypsum is sufficient.
