CEMENT GRINDING SYSTEMS
The final manufacturing stage at a cement plant is the grinding of cement clinker from the kiln, mixed with 4-5% gypsum and possible additives, into the final product, cement . In a modern cement plant the total consumption of electrical energy is about 100 kWh/t . The cement grinding process accounts for approx. 40% if this energy consumption.

Efficient grinding unit selection impacts profitability
Therefore, producing cement with less energy is becoming a key element of profitability: as the grinding process consumes about 60 per cent of the total plant electrical energy demand and about 20 per cent of cement production variable cost. So efficient grinding unit selection impacts profitability of cement manufacturing.

Clinker grinding technology in cement manufacturing
By. admin. Clinker grinding technology is the most energy-intensive process in cement manufacturing. Traditionally, it was treated as "low on technology" and "high on energy" as grinding circuits use more than 60 per cent of total energy consumed and account for most of the manufacturing cost. Since the increasing energy cost started …
