TSHP = + = Assuming a drive efficiency of 85% resulting in a total drive horsepower of, a standard 2 horsepower motor would be selected for the drive input. The horsepower required for the above conveyor may also be determined graphically by the use of the two horsepower nomographs.
The model then yields the operating parameters ( capacity and energy consumption of the mill, torque of the rolls, bulk density of the flake), which will result from the operation of the mill.
Calculate the driving power of a Drag Roller Chain Conveyor, commonly used in Sugar Plants considering the following sketch below: Where: Q Chain conveyor capacity = 90 tph; δ Sugar cane bulk density = 900 kg/m³ (56 lb/ft³); v Conveyor speed = 5 m/min ( m/s) ( fpm);
Once we know the effective belt tension, Te, we can calculate the power required to drive the belt. Required power equals the required belt pull times the belt speed. Required power = Te x V. Since Te is expressed in pounds and V, belt speed, is expressed in fpm, the product equals a certain number of footpounds per minute.

Average kWh/ton of material ground = 2608/150 = 174 kWh. Power consumption per ton of clinker with a conversion ratio for consumption : 1 = x = 27 kWh/ton. Using 4% gypsum 1 ton clinker = tons of cement. Therefore power consumption per ton of cement = ~ kWh.
In this study, the first and second law analysis of a raw mill is performed and certain measures are implemented in an existing raw mill in a cement factory in order to reduce the amount of energy consumption in grinding process. The first and second law efficiencies of the raw mill are determined to be % and %, respectively.
The acceleration factor of the ball or rod mass is a function of the peripheral speed of the mill. Thus. n = c9np/√D, the above equation becomes P = f1 (D²)·f5 (πD c9 np/√D) = cs np As a first approximation, the capacity, T, of a mill may be considered as a function of the force acting inside the mill.
