The crushed silica goes to a grinding machine for grinding to separate it from impurities as much as possible and achieve optional particle size. The specific process is as follows: after the crushing process, the material enters a belt conveyor to the powder bin for storage, and a vibrating feeder transports the material to a ball mill for ...
In silica sand processing plant, the grinding equipment is mainly rod mill, which has better grinding effect, controllable discharge particle size and certain scrubbing function. The particle size of silica sand mill is usually between 40 mesh and 120 mesh.
