Firstly, what is coal vertical mill production process ? Second, what coal vertical mill working principle is it? After coal vertical mill feed, with the rotation of the disc from the center to the edge of the movement, at the same time the material is extrusion and grinded by the coal vertical grinding mill roll .
Similar to the ring and ball mill, the vertical spindle roller mill uses large "tires" to crush the coal. These mills are usually found in utility plants. Raw coal is gravity-fed through a central feed pipe to the grinding table where it flows outwardly by centrifugal action and is ground between the rollers and table.
Loesche developed the 4-roller coal grinding mill with four tried and tested modules for throughputs over 150 t/h. The develop-ment was first realised in 1970 for grinding mills in the cement industry. This number of rollers also enables operation with only one pair of rollers to increase control response availability and flexibility.
Ball mills are cylinders partially filled with a spherical grinding medium used to grind material. Coal mills grind coal into powder using heavy rollers. The rollers crush the coal into a powder. Concrete crushers are pulverization equipment used in the crushing or breaking of concrete into concrete aggregate.
Vertical roller mills (VRM) can replace ball mills or tube mills used for preparing coal. Today VRMs with capacities up to 50 tph are the dominant technology for coal grinding. According to MIIT, grinding media wear in a VRM will only be 5 to 10 g/ton of coal powder, as compared to 100 g/ton of coal powder in a ball mill.
