YGM High Pressure and Medium Speed Mill

The high-pressure medium-speed mill is fastened with a high-pressure spring with a pressure of 1000-1500 kg on the roller hanger. Under the action of the high-pressure spring and centrifugal force, the roller rotates around the main shaft and rolls close to the grinding ring. Its rolling pressure is 1.2 times higher than that of the Raymond mill, so the output is greatly improved.

When the material to be ground enters the grinding chamber, it is scooped up by the scraper and sent to the grinding roller and grinding ring to roll. The rolling powder is brought into the analyzer with the circulating wind of the fan. Qualified fine powder flows into the cyclone powder collector with the air to become the finished product. The large particles fall back to be re-grinded, and the circulating wind returns to the fan. Repeat the above process, and the remaining air enters the pulse dust collector for purification.

When the grinding roller and the grinding ring reach a certain wear, adjust the length of the high-pressure spring to maintain a constant rolling pressure between the grinding roller and the grinding ring, thereby ensuring stable output and fineness.
