vertical roller mill operation

Product Description: High-pressure micro-grinding mainly by the host, blowers, ultra-fine analysis machine, the finished product cyclone powder, a bag filter and connecting duct piping and other components, greater scope compared with the jet mill. Red Star has produced high-pressure micro-grinding small investment, high income advantage.

Product advantages

Advanced structure, good performance

Pressure micro-grinding having overlapping multi-pole sealed grinding device, good sealing performance. Compared with other similar mill, roller grinding pressure of the material under the influence of high pressure increase 800-1200Kg spring.

The scope of large, energy-efficient

High-pressure micro-grinding of feed size large, the average particle size of the material can reach a one-time <6.5um ultra-fine powder. High-pressure micro-grinding and jet mill compared to apply a wider range. High-pressure micro-grinding effect of dust fully meet the national dust discharge standard.

Energy-efficient, high-yield

Small investment, high returns. In the same yield and fineness of cases, the price is only one-eighth of the jet mill. In the same yield and fineness, the system energy consumption is only one-third of the jet mill.

After the material is crushed by the elevator into the storage bin, and then by vibrating feeder evenly into the grinding chamber, after the shovel blade into being crushed between the roller and rubbing grinding ring, fans will be blown into the grinding room, blowing the powder into the analysis machine, be winnowing, reach fineness and regrinding, qualified powder into the air the finished product cyclone powder collector, separated air is discharged from the discharge port finished products. Material containing some water, would produce a certain moisture grinding, and the entire pipeline due to the tight seal is not absolutely certain external causes gas is inhaled, the system circulating air volume increases, in order to ensure the mill work under negative pressure, the excess amount of wind after entering the baghouse purification into the atmosphere.
