Application:

This machine is widely used in quartz, recrystallization, calcite, potassium feldspar, talc, marble, limestone, dolomite, fluorite, lime, activated clay, activated carbon, bentonite, kaolin, cement, phosphate rock, gypsum, graphite, glass. , manganese ore, titanium ore, copper ore, chrome ore, refractory materials, thermal insulation materials, coal char, coal powder, carbon black, clay, bone powder, titanium dioxide, iron oxide, etc. Mohs hardness below 9.3, humidity below 6% Non-flammable and explosive minerals, construction, chemical, fertilizer and other industries, more than 300 kinds of materials for high-fine milling, the finished product size in the range of 30-425 mesh (0.613 mm - 0.033 mm), according to the needs of a small part The highest fineness of the material can reach 1000 mesh (0.013 mm).

Working process:

In the main machine of the high-strength mill, a high-pressure spring with a pressure of 1000-1500 kg is fastened on the roller hanger. After starting work, the grinding roller rotates around the main shaft, and under the action of the high-pressure spring and the centrifugal force, it is pressed against the grinding ring, and the pressure is 1.2 times higher than that of the Raymond mill under the same dynamic condition, so the output is greatly improved. When the material to be ground enters the grinding chamber, it is shoveled by the blade and sent to the grinding roller and the grinding ring for rolling. After rolling, the powder is brought into the analysis machine along with the circulating air of the blower, and the qualified fine powder is mixed with the airflow into the cyclone. The device is the finished product, and the large particle material falls back to the regrind. The circulating air is returned to the blower and the above process is repeated, and the residual air is purified by the bag filter. When the wear of the grinding roller and the grinding ring reaches a certain level, the length of the high pressure spring is adjusted to maintain a constant rolling pressure between the grinding roller and the ring. This ensures a stable output.
