This study is concerned with evaluating the performance of a novel roller mill, in which the crushing platen is a vertical wall over which cylindrical rollers rotate, thereby crushing a raining bed of particles. It has been manufactured by International Innovation Technologies, Gateshead, UK. It has a small footprint, suitable for limited space.
In grinding of a raw material by a vertical roller mill, highly-efficient grinding is performed irrespective of the type of the raw material, and the life of the mill roller is extended. In order to achieve these, in a grinding roller (10) used in a vertical roller mill, an outer circumferential surface (12) of the roller as a grinding surface is divided into a main grinding …

Vertical roller mills (VRM) have become increasingly popular in recent years, as more cement producers look to increase their use of clinker substitute materials instead of importing clinker to meet localized rises in cement demand. The demand for cement has grown rapidly in recent years, creating a need for a more efficient way to grind clinker and other raw materials used in …
of 80mm. The raw materials are mixed in a certain proportion and fed into a vertical roller mill (LOESCHE mill). The vertical roller mill grinds the marital to D 85 of 90µm. The ground product is calcined in a preheater to 850-900℃. After calcination, the materials enter to a rotary kiln and heated to 1450℃ to become clinker.
