Drying in cement company means reducing the water in slag and other materials to improve the grinding efficiency, so as to achieve the purpose of energy saving. If the temperature is too low, the evaporation intensity will be reduced. If you need to maintain the same output, the heat exchange area will increase, the larger the equipment is, more cost will be.
.
Drying process is very important in slag grinding. The drying temperature can not exceed 450 degrees. If it is more than 450 degrees, the activity of slag will be reduced. This is the reason in recent years, Kefid large vertical mill can be widely used in the cement industry.
The vertical mill produce by Kefid is a large scale grinding mill which set crushing, drying, grinding, powder selecting in one, the supporting hot air furnace adopts hot air to transport materials.The materials with the large water content can be controlled by the inlet air temperature to meet the required water content.If you use large vertical mill and supporting drying equipment, the effect will be better.
