The complete equipment of grinding production line is mainly composed of jaw crusher, bucket elevator, silo, vibration feeder, main machine of grinding machine, fan, powder collector, bag dust collector and so on. When the machine is working, the bulk material is broken by the jaw crusher to the particle size suitable for entering the mill, which is sent to the bin through the bucket elevator. The vibration feeder at the bottom of the bin evenly sends the material into the main machine of the mill for grinding. After grinding, the fine powder that meets the particle size requirements enters the powder collector with the air flow through the analysis machine, and is discharged through the discharge valve at the bottom of the powder collector. The coarse powder that does not meet the size requirements is returned to the grinding chamber for re-grinding.
