raymond grinder mill brief introduction
raymond grinder mill is on the basis of plentiful market research, combining lots of statistical analysis about suggestions from domestic and foreign users and the innovative design from the traditional roller mill.
Material is forced off the table by centrifugal force, where it is then swept up into an airstream to a classifier immediately above.
raymond grinder mill main structure
Vertical roller mill is including the classifier ,roller ,plate,pressure ,reducer,motor,shell equipement and so on.The seperator is a kind of high-efficient and energy-saving equipement .And the roller is a kind of spare parts used to grind and crush the materials .The plate is installed on the output axis of the reducer ,which is the place the materials is crushed by the roller.And the pressure equipment is a kind of spare parts providing the pressure to the grinding roller ,thus crushing the materials.
raymond grinder mill application
Vertical roller mill is mainly suitable to crush the medium hard materials with the crushing pressure of less than 170MPa,and surface moisture of less than 8%.And vertical roller mill is very suitable to crush some brittle materials such as cement clinker, limestone, gypsum, coal gangue, slag, iron ore in the cement field.
raymond grinder mill working principle
raymond grinding mill drives the central shaft by the transmission device. On the top of the shaft, there is a plum-blossom frame, it is equipped with grinding roller, which forms the swinging pivot, grinding roller revolve around the grinding ring, at the same time, the roller itself revolves on its axis. At the bottom of the plum-blossom frame, there is shovel knife system, the shovel knife can put the materials into the place of the roller and the ring to form materials layer, this material layer can produce the centrifugal force (namely the impact extrusion) to crush material. Through all the process, it can reach the purpose of making powder.
