How does the Raymond mill work? The working principle of the pulverizer equipment is that the stone material falls directly from the upper part of the machine into the high-speed rotating turntable; under the action of high-speed centrifugal force, another part of the flying stone that is divided by the umbrella type around the turntable generates high-speed collision and ...

Coal Pulverizer Inlets and Outlets. Louvres (nozzle ring) around the outer perimeter of the grinding table allow hot gas to flow into the grinding mill through the mill base. Some of the pulverized coal is transported from the base of the mill up to the classifier by the hot gas stream i.e. the coal is transported pneumatically.

When the ball mill is running, most of the energy is converted into heat. The heat generated by the ball mill combined with the temperature of some raw materials causes the temperature to rise, which promotes the axial thermal deformation of the hollow shaft. Therefore, the expansion during operation must be considered during installation.
