SY spin mortar roller mill , which the original CRIMM the first batch of grinding experts of the State Council special allowance winner Professor Wang Guifu scceeded in developping for some vertical mills whose roller bearing life is short , high energy consumption , low operating efficiency and a series of serious defects is new vertical roller mill patented product (Patent No ZL 2005 2005 917.9)
Construction and Working Principle
SY Series rotating roller mill mortar for the vertical structure is made up of transmission system grinding system and the body . Generally, drive system used low-speed motor drive pulley directly to decelerate, that is stable and reliable. Grinding system is by a rotating cone-shaped millstone and several passable adjust clearance, rocker shaft is installed on the body outside,that is simple structure and very low failure rate(safe). When it works , material from the upper feeding mouth to the bottom of millstone, and it moves up the inwall of millstone in under the action of centrifugal force, while grinding roller turns on iteself in the resistance of the material.In addition, the material which is repeatedly laminated in the upstream process is rubbed. In the end , the material expel from the bottom under gravity.
