Low speed tube mill is mainly used in thermal power station for pulverizing coal of different hardness,and also in metallurgical,building material,chemical and textile industriex for producing coal powder,it has haih adaptability,reliable operation,easy maintenance and advanced technoloay.the mill is divided into six series,seveen specifications.
The mill consists of feeding device,driving assembly,rotating assembly,bearing unit,discharge chute and foundation unit,Raw coal and heat air go into the rotating assembly through the feeding device.As the shell rotates,grinding medium is raised to a height.then fal down,impact the coal and make it into powder because of the the gravity.The pulverized coal is carried to the silo through the screen,the oversize material is sent back to the shell and ground again.
