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

vertical roller mills Vs ball mills has long been a raging debate in the cement industry. In spite of the fact that vertical roller mills have been around for over ten years now and have gradually become the standard as far as cement manufacturing goes, several cement manufacturers still prefer ball mills for cement production when they want to design new grinding plants or a new integrated the advantages of the vertical roller mill include a high level of grinding efficiency combined with reduced energy consumption. for raw materials and cement clinker, the vertical roller mill is an excellent grinding solution because of the relatively lower cost of installation, ease of operation and maintenance, energy efficiency and product tumbling mills. these contain a charge of loose crushing bodies-the grinding medium-which is free to move inside the mill, thus comminuting the ore particles. the grinding medium may be steel rods, or balls, hard rock, or, in some cases, the ore itself. In the grinding process, particles between and 250 nun are reduced in size to
