High pressure micro powder mill structure

The high-fineness pulverizer is composed of coarse crushing, fine crushing, wind conveying and other devices, and achieves the purpose of the pulverizer in the form of high-speed impact. The wind energy is used to make powder in one time, eliminating the traditional screening process. In the main body of the high-pressure micro-powder mill, a high-pressure spring with a pressure of 1000-1500 kg is fastened on the roller hanger. High-strength mill. After the high-strength mill starts working, the roller rotates around the main shaft and rolls close to the grinding ring under the action of the high-pressure spring and centrifugal force. The pressure is 1.2 times higher than that of the Raymond mill under the same power conditions, so the output is greatly improved. When the material to be ground enters the grinding chamber, it is scooped up by the shovel and sent between the grinding roller and the grinding ring for rolling. After rolling, the powder is brought into the analyzer with the circulating air of the blower. The qualified fine powder flows into the cyclone powder collector with the air as the finished product, and the large particles fall back to the re-grinding. The circulating air returns to the blower and repeats the above process, and the remaining air enters the bag dust collector for purification. When the wear of the grinding roller and the grinding ring reaches a certain degree, adjust the length of the high-pressure spring to maintain a constant grinding force between the grinding roller and the ring. Thereby ensuring a stable output
Performance characteristics of high-pressure micro-powder mill
1. Compared with the airflow mill, the high-pressure micro-powder mill has a wider range of applications.
2. Compared with other similar mills, the grinding force of the grinding roller on the material is increased by 800-1200Kg under the action of the high-pressure spring.
3. Energy saving. Under the same output and fineness, the system energy consumption is only one-third of that of the airflow mill.
4. Small investment and high returns. Under the same output and fineness, the price of the high-pressure micro-powder mill is only one-eighth of that of the airflow mill.
5. The feed particle size is large, and the one-time average particle size of the discharge can reach 6.5um ultra-fine powder.
6. Overlapping multi-pole sealed grinding device with good sealing performance.
7. The dust removal effect of the high-pressure micro-powder mill fully meets the national dust emission standards.
