Description of powder grinder machine
powder grinder machine is a new R&D mill. It is designed by engineers based on many years' industrial mill research and the needs of mill industry. The adoption of world leading powder processing technology makes zenith grinding stone machine starts a new era of mill industry with high efficiency and low consumption. It is the ideal substitute of the traditional Raymond mill. powder grinder machine is widely used in construction, mining, building, chemical, metallurgy industry, coal industry, electric power industrial and steel industry, etc. The output size is between 80-425 mesh, while it can be adjusted to 30-80 mesh by installing special devices.
powder grinder machine working principle:
Inside the host of high pressure grinding mill, a high pressure spring with 1000-1000 kg pressure is tightened on roller hanger.
In the working process, grinder roll rotates around principal axis, and appresses the ring rolling under the effects of high pressure spring and centrifugal force so that its pressure is 1.2 times higher than that of Raymond mill under the condition of same power.
When the materials to be ground enter into grinding chamber, they are scooped up by shovel knife and sent between grinding roller and grinding ring for grinding, then powders are taken in analytical engine along with the recirculating air; qualified fine powders flow into whirlwind powder collector along with the gas and become finished product, meanwhile, large particle materials fall back for re-grinding.
Features of powder grinder machine
1.The unique design improves the handling capacity;
2.It can process the materials under Mohs hardness 9.3;
3.The adoption of multi-class seals keeps the grinding equipment tightly closed;
4.Long life of grinding rollers and rings;
5.powder grinder machine meets the requirement of national dust-dump standard;
