Introduction:
The three ring medium speed superfine grinding machine is mainly used for processing non flammable and explosive brittle materials with medium and low hardness and Mohs hardness ≤ 6, such as calcite, chalk, limestone, dolomite, carbon black, kaolin, bentonite, talc, mica, magnesite, illite, pyrophyllite, vermiculite, sepiolite, attapulgite, rectorite, diatomite, barite, gypsum More than 100 kinds of materials, such as alunite, graphite, fluorite, phosphate rock, potassium ore, pumice and so on, the fine powder particle size can be adjusted between 325-3000 mesh, and the output can reach 0.6-6.5 tons per hour.
Advantage:
1. High efficiency and energy saving. When the fineness of the finished product and the power of the motor are the same, the output of the air flow mill, stirring mill and ball mill is more than double.
2. Long service life of wearing parts. The grinding roller and ring are forged with special materials, so the utilization degree is greatly improved. When the fineness of materials and finished products are the same, the service life of wear parts of impact crusher and Turbine Crusher is 2-5 times longer than that of impact crusher and Turbine Crusher, and the service life can reach 2-5 years when processing calcium carbonate and calcite.
3. High safety and reliability. Because there is no rolling bearing and no screw in the grinding chamber, there is no problem that the bearing and its sealing parts are vulnerable, and there is no problem that the screw is easy to loose and destroy the machine.
4. High fineness. The fineness of HGM three ring medium speed superfine grinding can reach D97 ≤ 5 μ m at one time.
5. Environmental protection and cleaning. Using pulse dust collector to capture dust and muffler to reduce noise, it has the characteristics of environmental protection and cleaning.
Working principle:
When working, the main motor drives the spindle and turntable to rotate through the reducer, and the roller pin at the edge of the turntable drives dozens of grinding rolls to roll in the grinding ring raceway.After being crushed into small particles by hammer crusher, the large materials are sent to the storage bin by the elevator, and then the materials are evenly sent to the bulk tray on the upper part of the rotary table through the vibrating feeder and inclined feeding pipe.Under the action of centrifugal force, materials disperse to the periphery of the circle and fall into the raceway of the grinding ring, which is impacted, rolled and ground by the ring roller. After being processed into powder by the three-layer ring, the high-pressure fan sucks the external air into the machine by suction, and brings the crushed materials into the separator.The rotating impeller in the separator makes the coarse material fall back to regrind. The fine powder meeting the requirements enters the cyclone dust collector with the air flow and is discharged by the discharge valve at the lower part. The airflow with a small amount of fine dust is purified by the pulse dust collector and discharged through the fan and muffler.
