Vertical Roller Mill For Cement Grinding:

the working principle of the vertical roller mill is similar to that of the trapezoidal mill. the material is also crushed in the gap between the grinding ring and the grinding roller. however, the grinding ring of the moving crusher is very large, and the grinding roller is composed of several layers together to form the grinding cavity.the grinding process in ball mills and vertical roller mills differ fundamentally. In a ball mill the comminution takes place by impact and attrition. the comminution in the vertical roller mill takes place by exposing a bed of material to a pressure sufficiently high to cause fracture of the individual particles in the bed, although the vsi mill throws rock or ore particles against a wear plate by slinging them from a spinning center that rotates on a vertical shaft. this type of mill uses the same principle as a vsi crusher.. tower mill. tower mills, often called vertical mills, stirred mills or regrind mills, are a more efficient means of grinding material at smaller particle sizes, and can be used after ball mills in a
