The difference between vertical roller mill and ball mill The ball mill is generally composed of a horizontal cylinder, a hollow shaft for feeding and discharging, and a grinding head. The cylinder body is provided with an abrasive body, the cylinder body is made of steel plate, and the steel lining plate is fixed with the cylinder body, and the grinding body is generally a steel ball, and ...


spherical roller bearings, chosen for their ability to manage high radial loads and the presence of misalignment. Spherical roller bearings self-align and thus better compensate for shaft delections and seat misalignment. Cone Crushers Cone or gyratory crushers use a variety of specialized bearings speciically designed for each model.

How to choose China vertical roller mill (the output is more than 300t/d) The vertical roller mill has a grinding fineness of 200-400 mesh, so the general processing material yield is large, and the grinding is not as fine as the Raymond mill, resulting in a decrease in yield. The grinding materials generally used for the concrete and cement mixture are ground by vertical roller mill.
