The vertical roller mill is well known in the cement and power plant industries as the preferred mill for grinding of raw materials. It is increasingly used as a solution for efficient grinding. Within the cement industry, vertical roller mills are becoming more important as more cement producers look to increase their use of clinker substitute materials instead of importing clinker to meet ...
For power, torque and cutting force calculations, the specific cutting force, or k c1, is can be explained as the force, F c, in the cutting direction (see picture), needed to cut a chip area of 1 mm² that has a thickness of 1 k c1 value is different for the six material groups, and also varies within each group. The k c1 value is valid for a neutral insert with a rake angle ...

· Specific power consumption for clinker/gypsum grinding in a ball mill should be approximately: 3000 cm2 /g kWh/t 3200 cm2 /g kWh/t 3400 cm2 /g kWh/t 3600 cm2 /g kWh/t 3800 cm2 /g kWh/t 4000 cm2 /g kWh/t Note: The specific power demand of large grinding units is 1015% better than that of small mills. Calculation of .
To remove ambiguity we might call it "average power", or "load", or "demand". "Energy usage" and "energy consumption" are somewhat loose terms that can be used to refer to the rate of energy usage ( 10 kW) or the total amount of energy used over a specified period ( .
The desired throughput of the mill is multiplied by the specific energy to give the mill power requirement, which is used in turn to size a mill for dimensions, internal geometry and loading conditions to match the power draw. The most frequently used powerbased methodologies for calculating energy requirements for comminution circuits using AG/SAG mills are concisely presented in the ...
