Cement drying is to reduce the moisture content of slag and other materials, its purpose is to improve the grinding efficiency and realize energy saving and consumption reduction. Too low temperature will also lead to a decrease in evaporation intensity. If the same output needs to be maintained, the heat exchange area will increase, which means that the equipment specification is large and the cost of purchasing equipment by customers will increase.

The drying process of slag grinding is very important. The drying temperature should not exceed 450 degrees. If the temperature exceeded 450 degrees, the activity of slag would be reduced, which would damage the potential benefits of customers. This is also the reason why in recent years, the VM - Vertical Grinding Mil of kefid has been widely used in the cement industry.

The large VM - Vertical Grinding Mil produced by Kefid is a kind of large-scale grinding equipment which integrates fine grinding, drying, grinding and powder selection. The matching hot blast stove uses hot air to convey materials, and when the moisture content of the materials is high, the product can reach the required moisture content by controlling the inlet air temperature. The effect will be better if the VM - Vertical Grinding Mil is used together with the drying equipment.
