High pressure micro powder mill is manufactured on the basis of in Raymond grinding through long-term practice examination research, hereinafter referred to as high pressure micro powder mill, high pressure, high pressure grinding mill. High pressure micro powder mill is a kind of ultrafine mill, which can be grinding barite, limestone, ceramics, slag, etc mok's hardness is
 not more than 9.3 level, humidity under 6% of inflammable and explosive of the mining, metallurgical, chemical industry, building materials, and other industries more than 280 kinds of materials of high fine powder processing，the finished product size adjusted
in the range of 80-425 mesh range adjustment (the most fine 1000 mesh).
High pressure micro powder grinding performance characteristics:
1.the high pressure micro powder is more widely used than jet mill；
2.the high-pressure micro powder mill compared with other similar mill，the grinding pressure of the roller material under the action of
high-pressure spring to improve 800-1200kg；
3.energy saving.The same output and fineness, energy consumption is only one-third of the jet mill.
4. small in investment and high in profit. Only one eighth of price compared with pneumatic mill.
5.. big feeding size and small discharging size (average one-off size is 6.5um).
6. high airproof ability with multi-grade sealing device.
7. the de-dusting effect is fully comply with national standard
