Cement clinker. Typical clinker nodules. Hot clinker. Cement clinker is a solid material produced in the manufacture of portland cement as an intermediary product. Clinker occurs as lumps or nodules, usually 3 millimetres ( in) to 25 millimetres ( in) in diameter. It is produced by sintering (fusing together without melting to the point ...
The answer is the cement industry. Limestone plays two major roles in the cement manufacturing process, one is used as a raw material for cement clinker, and the other is used as a cement admixture. Limestone is one of the key raw materials of cement clinker. Around 8090% of the raw material for the kiln feed is limestone.
The energy consumption of the total grinding plant can be reduced by 2030 % for cement clinker and 3040 % for other raw materials. The overall grinding circuit efficiency and stability are improved. The maintenance cost of the ball mill is reduced as the lifetime of grinding media and partition grates is extended.
