Rules of thumb Raw material: 1016 kWh/t (mill motor) target fineness: passing 200µm>99%, passing 90µm>88% depending upon burnability of raw mix) Cement: For a pure cement (95% clinker) at 3500 cm2/g, the mill motor consumption should be <40 kWh/t. (Clinker grindability: approx 32 kWh/t at 3000 cm2/g (mill motor).

The kiln has an operation capacity of 90 t/h and upper bound of 110 t/h. A total of 57 t/h of the clinker is produced inside the kiln. For the heating of the raw mill, kiln raw meal, and a coal mill, hot flue gases from the kiln are deployed. Gases exit from a preheating tower with a temperature at about 370°C.

Cement emissions intensity has remained relatively stable since 2018, at just under t CO 2 per tonne of cement produced, following several years of modest increase largely due to an increasing clinkertocement ratio in China. To get on track with the NZE Scenario, emissions must fall by an average of 3% annually through to 2030.

Cement manufacturing brief description of a cement mill. Cement clinker is usually ground using a ball mill. This is essentially a large rotating drum containing grinding media normally steel balls. As the drum rotates, the motion of the balls crushes the clinker. The drum rotates approximately once every couple of seconds.
