sections and the clinker conveyor gallery. The clinker dust is sufficiently abrasive dark gray powder, the fineness of grinding determined by screening using sieve No. 008 showed a residue of 23%. Aspiration dust is light beige powder, much more dispersed than clinker dust, and the fineness of grinding showed a residue of 18%.

Clinker grindability is determined by quantity of electricity consumed for grinding (kW / ton) under other equal conditions. In cement production entire crushing and grinding process consumes about 85% of the electricity. At the same time 75% of electricity consumed for milling and only 2-20% of them consumed for grinding.
