Coal mill is one of the four auxiliary engines of a thermal power station. It is the main equipment of the pulverized coal preparation system and mainly used for grinding coal of multiple hardness. It is also suitable for coal and ore raw materials in cement, metallurgy and chemical industries. The special steel ball coal mill for power plants is a new type of equipment, which is widely used in thermal power plant equipment.
The raw coal enters the feeding device of the mill from the feeder equipment, and the hot air having a temperature of about 300 °C also enters the feeding device through the air inlet pipe. A special lifting plate is arranged in the drying chamber to raise the raw coal so that the raw coal is subjected to intense heat exchange here to be dried. The dried coal block enters the grinding chamber through a double-layer compartment plate with a lifting plate, and the grinding chamber is provided with steel balls. The coal block is pulverized and ground into pulverized coal in the chamber. At the same time that the coal block is pulverized, the pulverized coal powder and gas are taken out of the mill together by a special draft fan through the discharge device of the mill. The coarser particles are returned to the powder through the return screw of the discharge device and ground again in the grinding chamber.
The coal mill has been improved on the basis of traditional equipment, the output has been greatly improved, the discharge powder is finer, and the operation is more stable.
01The feeding device of the coal mill adopts the louver type structure with oblique inlet and oblique feeding, which makes the feeding smoother; the discharging device adopts the curved tube structure, and the discharging is not blocked, which improves the production capacity.
02Compared with the traditional mill, the coal mill can work continuously in the harsh environment, which is 4-6 hours longer than the original mill, and brings considerable benefits to the customers.
