Raymond Mill Mineral Stone Raymond Grinding Mill Machine Ore Grinding Mill
1. Raymond mill main structure
The machine structure is mainly composed of main machine, analyzer, fan, finished cyclone separator, micro powder cyclone separator and air duct. Among them, the host machine consists of a frame, air inlet volute, shovel, grinding roller, grinding ring, cover shell.
2. Working principle of Raymond mill:
Work, will need to crush materials from hood shell side into the hopper add machine, relying on roller device of hanging on the host plum flower shelf, around the vertical axis of revolution, itself rotates at the same time, due to the effect of rotating centrifugal force when the roller swing outward, press in ring, the shovel knife scooping up material to between grinding roller and grinding ring, The purpose of crushing materials is achieved by rolling and pressing the grinding roller.
Air selection process: after the material is ground, the fan will blow the wind into the main machine housing, blowing the powder, sorting by the analyzer placed above the grinding room, the fine and coarse materials fall into the grinding room for regrinding, fineness in accordance with the specifications of the wind into the cyclone collector, collected after discharging through the powder outlet, that is, the finished product. The air flow is returned to the fan by the return duct at the upper end of the big cyclone collector. The wind path is circulating and flows under negative pressure. The increased air volume of the circulating air path is discharged through the exhaust pipe between the fan and the host machine, and enters the small cyclone collector for purification treatment.
