Working principle

 

Tube Coal Mill is driven by a motor via a pin coupling, a spur gear speed reducer, and an open gear reduction drive to drive the rotating part of the mill to rotate in a simplified manner. The grinding machine is equipped with a ball of grinding media. When the cylinder rotates, the steel ball, which is rotated by the centrifugal force and friction force, is lifted to a certain height and then dropped by its own gravity. The coal in the simplified coal forms pulverized coal under the impact and grinding action of the falling steel ball. The pulverized pulverized coal is sent to boiler burning or pulverized coal storage for pneumatic equipment of the pulverizing system.
