Hello Sidhant, The factor of 102 is used to convert mmWC into pascals because the formula for the static fan efficiency in SI units is;-. Static Fan Efficiency = Volume (m3/s) * Pressure gain (Pa) / Power input (W) * 100. But, if the pressure is measured in mmWC instead of Pascals and Power is expressed in kW, the formula can be derived as

Finally, the material efficiency of the units and stages as well as the waste recycle rates during these stages is calculated. The results show that approximately 2.48 t, 4.69 t, and 3.41 t of materials are required to produce a ton of the product in raw material preparation, clinker production, and cement grinding stages, and their waste rates

Ball Mills can be supplied with either ceramic or rubber linings for wet or dry grinding, for continuous or batch type operation, in sizes from 15″ x 21″ to 8′ x 12′. High density ceramic linings of uniform hardness male possible thinner linings and greater and more effective grinding volume.
