1.Low operation Cost

(1)、High grinding efficiency: The roller grinds materials on the mill directly, which makes the energy consumption is 30%~40% less than the one of Bill Mill.

(2)、Little Wear: The roller and lining plate are made of premium material to have long service life.

Because the hot wind dries the materials in the mill, a drying machinery is saved. And the temperature of hot wind can be controlled to suit different moisture conditions of different materials.

The materials stayed shortly in the mill for easily detecting and controlling of the fineness and chemical composition of products, which can make the final size stable. There is few Ferric in final powder and the ferric content come from mechanical wear is easy to remove, the whiteness and purity is high, especial for processing white material.

The thin oil lubrication station attached to the mill makes the roller shafts lubricated circularly, providing them with a working environment of low temperature and pure lubrication oil, extending their service lives, and ensuring their stability.

Hydraulic device is adopted to control the acting force, and the acting force can be automatically adjusted according to different grindability of the raw material, which keeps the grinding mill in a perfect condition, not only reducing the consumption of the idle work, but also prolonging the using life of rollers and liners.

The drive system consists of main motor, coupling and speed reducer. New-type Spiral bevel and planetary drive system are adopted by the speed reducer. The Babbitt thrust tile with strong wearability can bear more pressure load, which also increases the service life.

The mill is equipped with an auto-control system which allows PCL, centralized and DCS control, which makes the operation much easier and meets the different needs from the customers.

Two different classifiers are adopted according to different material and different requirements for fineness. Meanwhile the frequency of the classifier is controllable, which ensures well-distributed particle size and higher product fineness.

The mill makes small noises in its running because there is no direct contact between rollers and the grinding table, so it reduces 20-25 dB than that of ball mill. Plus, the vertical mill is totally sealed and the whole system works in negative pressure, making little dust.
