Coal Ball Mill

Brief Introduction of Coal Ball Mill

Coal ball mills are widely used in thermal power plant equipment, and also suitable for processing limestone, cement clinker, clay, bauxite, active lime, aluminum hydroxide, etc.

Working Principle of Coal Ball Mill

The raw coal enters into the feeding device of the coal ball mill by the feeder, and the hot air with a temperature of about 300 ℃ enters the feeding device through the air inlet pipe. A special lifting plate is set in the drying bin to lift up the raw coal materials so that the raw coal can be dried through strong heat exchange here. The dried coal enters the grinding bin through the double-layer partition board with the lifting plate. The grinding body (steel ball) is installed in the grinding bin, and the coal block is crushed and ground into pulverized coal in this bin. When the coal block is crushed, the pulverized coal and gas will be taken out of the mill by the special induced draft fan through the discharge device of the coal mill and the coarse particles will be returned to the grinding bin through the return screw of the discharge device for regrinding.

Product Advantagesof Coal Ball Mill

1. High efficiency and energy saving

The coal ball mill has been improved on the basis of the traditional, the output has been greatly improved, the discharge powder is fine, and the operation is stable and reliable. It provides a new type of energy-saving grinding equipment for production enterprises.

2.High production

Because the feeding device of coal ball mill adopts the louver structure with oblique air and oblique feeding, which makes the feeding more smooth. While the discharging device adopts a curved pipe structure without blocked discharge, which greatly increases production capacity.

3.Continuous operation

Compared with the traditional ball mill, the coal ball mill not only realizes the advantages of high output and high fineness but also can work continuously in a harsh environment. It is about 4-6 hours longer on the basis of the original mill, which brings considerable benefits to customers.

4.Advanced equipment

Compared with the traditional mill, the coal ball mill has been greatly improved by adopting advanced technology and special structure design, with large output and fine powder.
