Introduction

Coal mill is used to both grind and dry coal resources with different hardness. It is composed of feeding device, main bearing, rotary part, transmission device, feeding and discharging device, high voltage starting device and lubrication system etc. and widely applied in industries like cement building materials, thermal power, metallurgy and chemistry etc. Air-swept coal mill is an ideal machine in coal powder preparation because of its reasonable structure and high grinding efficiency.

Advantages of Coal Mill

1. High grinding efficiency; the medium's impact number is five thousand times more than that of the ordinary ball mill.

2. High energy utilization ratio; the filling rate is as high as 80%-90%.

3. Little impurity and reaction between mediums; no needless impact.

4. The adoption of ceramic lining board and medium reduces abrasion to lining board and avoid iron pollution.

5. The integration of grinding and gradation reduces energy consumption.

6. Working under negative pressure prevents powder flowing out.
