Low running costs

Grinding roller squashes materials on the millstone directly, which can reduce 30 or 40 percent of energy consumption. Grinding roller doesn’t contact with millstone, so the service life will be longer.

High drying efficiency

Hot wind from outside will contact with powdery materials in the grinding mill directly. It can save a dryer because of high drying efficiency. Besides, it can meet requirements of materials with different humidity by adjusting the temperature of hot wind.

Green production process

There is slight shock and low noise. Hermetically-sealed structure makes no powder flow away when the machine works under negative pressure. It meets environmental protection requirements very well.

Stable product quality

Because of the short time materials staying in the grinding mill, it is easy to check and control the output size and stone composition in order to reduce repetitive milling and stabilize product quality.
