Grinding of cement clinker and granulated blast furnace slag in roller grinding mills (vertical airswept grinding mills) is a technology introduced by Loesche. The first use of a Loesche mill, with a grinding track diameter of only 1.1 metres, was used as long ago as 1935. However, the breakthrough in grinding this type of material on the vertical

Air-swept coal mill is the main equipment of cement plant, also called coal mill in cement plant, used for grinding and drying various hardness of coal, crushing the coal briquette into pulverized coal.It is the important auxiliary equipment of pulverized coal furnace. The air-swept coal mill runs reliably, can work continuously, also has a large production …

The ball mill cylinder is a hollow barrel, which is rolled and welded by several steel plates. The two ends of the cylinder are connected to the ball mill trunnion with end covers. As the main part of the ball mill, it has to bear the weight of the lining plate, grinding media, compartment plate, and grinding materials.

Vertical ball mills are not commonly used in industries due to their capacity limitation and specific structure. A vertical roller mill comes in the form of an erect cylinder rather than a horizontal type like a detachable drum. ... power range 18.5-800KW. During production, the ball grinding machine may be called a cement mill, limestone ball ...
