Air-Swept Coal Mill

Overview: The wind swept coal mill is used for drying and grinding coal powder. It mainly consists of a feeding device, main bearings, rotating parts, transmission device, rolling device, high-pressure starting device, and lubrication system. The raw materials are loaded into the mill through the feeding equipment, and hot air enters the mill through the inlet duct. As the mill cylinder rotates, coal and hot air exchange heat in the mill, and coal is crushed and ground in the mill. At the same time as coal is ground, fine powder is carried out of the mil...

Product Introduction Characteristics Technical Parameter

Characteristics

1. Reliable operation, continuous operation, and high production capacity
2. Less transmission components and lower maintenance costs
This is a design that highlights the advantages and disadvantages of the open flow grinding system, and makes significant improvements to the traditional ball mill. In addition to all the advantages of open flow grinding, compared with ball mills of the same specifications, the output of the mill has been greatly improved, and the powder is fine and the specific surface area has increased, achieving high yield and high fineness, providing a new type of grinding equipment for the production of high-grade cement.
