Energy-efficient equipments such as high-pressure grinding rolls vertical roller mills CKP pre-grinders Cemex ® mills and Horomills ® are used at both finish grinding of cement and raw material-grinding stages due to higher energy consumption of conventional multi-compartment ball milling circuits. Multi-compartment ball mills can be

Raw milling. The gas-swept vertical mill quickly became the raw mill of choice. Grinding energy was approximately 50 per cent of the ball mill and the drying capabilities allowed direct processing of materials of up to 20 per cent moisture content.

The big challenge in the Cement Industry Cement making is a power consuming business. Pyro string and downcomer are perfect spots to lower emissions and save energy with our flow meters. Even efficient vertical roller mills (VRM) offer an optimization potential by better and more reliable raw gas flow measurement.
