Power taken by the millThe power taken up by the vertical roller mill is givenby the following expressionN =( I. #181; .KT .DR . .n ) / 60 K WWhere,I = rollers#181; = friction factor ( for raw materials, for coal)T = specific roller pressure, kN/m2(400 800 for raw and coal)DR = roller diameter, mW = roller width, mDm = mean diameter of the track, mN = table
The basic parameters used in ball mill design (power calculations), rod mill or any tumbling mill sizing are; material to be ground, characteristics, Bond Work Index, bulk density, specific density, desired mill tonnage capacity DTPH, operating % solids or pulp density, feed size as F80 and maximum chunk size, product size as P80 and maximum and finally the type of circuit open/closed
As vertical roller mills are 30 to 50 percent more efficient than other grinding solutions, they give cement plant owners a great opportunity to maximise productivity and minimise operating costs. The high energy efficiency is especially beneficial in regions with limited power generating capacity or where electricity availability is limited.
rollers and the table of the vertical roller mill, able to sustain such a pressure without the material being squeezed away from the pressure zone. A stable grinding bed is usually easily obtained in raw material grinding in a vertical roller mill with a high efficiency separator. However, in cement grinding it becomes
