1. Application of Grinding Mill:
Grinding mill is used for grinding the material below scale 6 of mohs hardness and 250-odd sorts of non-inflammable and non-explosive stuff in the trades of mining, metallurgical industrial, chemical engineering and building material for high fine powder generation and processing, such as talcum, barite, marble, limestone, charcoal blacks.
2. Features of Grinding Mill:
<1. Wide application scope,can use to crush materials less than 6 moth of hardness.
<2. Under the effect of high pressure spring, the fineness of final product is increased greatly.
<3. Compared with Jet Milling, the energy consumption is lower.
<4. Less investment, high efficiency, recycling fast
<5. Independent system, less Production links, materials less than 25mm can be put into processing directly.
<6. No pollution, dedusting effect is completely meet national standards.
<7. The sealing effect of grinding roller device is good.
3. Working Principle of Grinding Mill:
High pressure grinding mill hosts 1000-1500kg 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 1.2times of Raymond powder machine under the same conditions,so the output is much improved.When the material is put into the 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 be 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 suitable yield and fineness under the steady pressure by adjusting the length of high-pressure spring.
