The clinker store is the source of supply for the cement grinding stage.
Additives are fed in during the clinker grinding process to achieve the required type and grade of cement.
The finished cement is transferred to storage silos, from which it is loaded into bulk transporters or bags.
The raw meal is preheated and calcined in the cyclone preheater and calciner..
The raw meal is burned in the rotary kiln at a temperature of around 1,500° C to form clinker.
Most of the heat given off during clinker cooling is recoverd for use in the production process.
The raw material is crushed to the size of coarse gravel.
The raw material is stockpiled or homogenised in blending beds.
The proportioning station feeds the raw material to the mill in the right quantity and composition.
The raw material is ground to the required fineness in the raw mill and simultaneously dried.
The raw material is homogenised and stored in silos, from which it is fed at a controlled rate to preheater.
