Raymond mill work principle:
In the work, the material to be crushed is added into the machine from the hopper on the side of the machine shell, and is revolved around the vertical axis by means of the roller device suspended on the main frame of the plum blossom rack. Meanwhile, due to the centrifugal force during rotation, Roller swing outwards, squeezing the ring, the blade shovel the material sent to the roller and the ring between the grinding roller rolling rolling to achieve the purpose of crushing the material.
Raymond mill model parameters are as follows:
