The transmitter in the rod mill is the steel rod‚which falls down vertically and contact with the ore.It has selective crushing function‚that is to crush the ore as order from big to small‚so the product ‘s grain size is even‚it suits for the rough mill or for the mine factory that requires the ore to go through the Fine Crusher. The adoption of the drum type feeder can solve the previous problem. Meanwhile the innovation should be made to sand return system of the grader
