Read OnTwenty field-scale tests were conducted in a 28 MW pulverized coal power plant in Healy, Alaska, to examine mill power consumption in relation to coal grind size. The intent in this field-scale study was to verify if grind size truly impacted power consumption by a detectable amount. The regression model developed from the data indicates that grind size does impact …
Read Onpower consumption) is [14, 15]: The total power of mill electric motor (power at mill load) is obtained from the expres-sion [14, 15]: where D 1 [m] is outer diameter of beater. Beater wheel mill M-12 diameter is [D 1 =4.2 m]. As well, the total power of mill electro motor based on energy consumption was calculated using the expression:

Read OnKey words: Hardgrove grindability index, mill, coal, mineral matter Introduction Coal is dominant energy source in Serbia, as it is used in power plants for electricity generation. Two open pit mines (Kolubara and Kosovo) with total year production of 35 Mt per year are used for 65% of total electricity production.
Read OnIllustration of the "grinding zone" on a MPS mill Horsepower/Ton Consumption Below is a typical HP/ton consumption chart based on our experience. However, keep in mind that power consumption varies with mill types but are also largely influenced by coal feed rate, HGI variations, spring pressures, coal fineness,
Read OnThe production rate is 24 t/h with a power consumption of 16.8 kWh/t at a fineness of 5% R0.090 mm. As second product coal is ground to 8.5% R0.090 mm with a production rate of 34 t/h and 7.3 kWh/t specific energy consumption for the mill main motor. These data show the wide range of applica tion for MPS coal grinding mills.
