Product introduction

High Pressure Medium Speed Grinder is called high pressure grinding mill, and it’s new type grinding mill designed and developed by Vipeak designing institute based on many years’ fine powder making machinery manufacturing experience, it is an international leading machine for high efficiency and low energy consumption. High Pressure Medium Speed Grinder could process barite, limestone, ceramic, slag and other 280 kinds of non flammable material whose Moh’s hardness is less than 9.3, moisture is less than 6%, it is applied powder milling in mining, metallurgy, chemical engineering and construction material industry fine powder process, final product size could be adjusted between 80-425 mesh (finest size could be 1000 mesh), 30-80 mesh coarse powder could be produced by adding a special device.

Product superiority

Classifier

Precision output size could be adjusted (0.613-0.033mm).

Grinding device

Eclipsed form multistage seal is adopted, excellent seal performance.

Spacer protective measures

Mainframe is under protection, easy to be replaced, maintenance cost is reduced.

Spring strengthens grinding force

Under the effect of spring, grinding force that roller impacting on material is increased by 800-1200kg.

Working principle

High pressure medium speed grinder mill hosts 1000-1500 kg high-pressure spring fastening on roller suspender. After working, grinding roller rotates around spindle and rolling close to the grinding ring under the high pressure spring and centrifugal force. Its rolling pressure is 1.2 times of Raymond powder machine under the same conditions, so the output is much improved. When the material is put into grinding chamber, it was grinded between grinding roller and grinding ring, the powder was brought into analytical machine by recirculation air from air blower, qualified powder was flowed into the cyclone powder collector, the large particles was going to regrind. Circulating air return to blower to repeat the above process and the left air entered the Wind bag filter for purification. When the grinding roller and grinding ring reached a certain wear and tear, which could ensure a stable yield and fineness under the steady pressure by adjusting the length of high-pressure spring.
