Abstract. LOESCHE vertical roller mills are widely used for the comminution of raw materials in the cement industry, for the comminution of clinker and blast furnace slag and for the production of pulverized coal for cement kilns, blast furnaces and power plants. Recent research has shown, that the application of these vertical roller mills in ...

In a vertical coal mill, drying, grinding, and separating/classifying of coal can be done simultaneously. Hence, production and energy efficiency is higher than those of a tube mill. The vertical coal mill works as follows: Wet coal is feed from the upper part or side of the mill onto the rotating table.

In the second set of test, the actual operation data of the coal mill was used for testing based on the trained model in the first set of test. During the test, the actual operation data of a coal mill for 5000 s was selected as the data samples, which contained the conditions of multiple coal interruption. The results are shown in Fig. 14.

Mediumspeed mill. Mediumspeed mills are smaller than lowspeed units and are generally of the vertical spindle construction. The speed of the grinding section of these mills is usually 75225 rpm. They operate on the principles of crushing and attrition. Pulverization takes place between two surfaces, one rolling on top of the other.
