1. The trapezium roller and grinding ring improve the grinding efficiency greatly. The roller and grinding ring are designed in inverted trapezium with different diameter, which reduce the slip velocity of materials between roller and grinding ring, extend grinding time, and improve the grinding efficiency.

2. With high efficient balanced adding pressure springs.Adopting the advantages of Raymond Mill and High Pressure Suspension Mill, Super Pressure Trapezium Grinder has longer service life. The roller assembly has been linked by the pulling pole and the levelled springs, with the radial force yeilding, which avoids the bulk material entering into the grinding chamber to wear down the principal axis and the the bearings, thus the service life will be longer.

3. Using flexible connection to connect main frame and powder concentrator, so the damping spring and airproof belt can reduce the vibration and noise, and avoid the resonance as well.

4. There is high desity and high precision impeller.

5. There is high-efficiency and energy-saving centrifugal induced draft fan.

6. With the impeller adjusting device brings more convenience. The clearance between housing and powder concentrator's blade front end also effects the fineness of the final product. The patent technology enables adjust the clearance more convenience.

TGM series Super Pressure Trapezium Grinder is widely used in Electric power, metallurgy, construction, chemical, mining industry, and etc. This machine is suitable for grinding the lump material into powder, such as silica sand, feldspar, calcite, talc, barite, fluorspar, rare earth, marble, ceramic, aluminum vanadium earth, manganese ore, iron ore, copper ore, phosphate ore, iron oxide red, slag, granulated slag, cement clinker, active carbon, dolomite, granite, garnet, iron oxide yellow, bean cake, chemical fertilizer, compound fertilizer, coal ash、soft coal、lignite, chrome oxide green, gold ore, red mud, clay, kaoline, coke, gangue, porcelain clay, kyanite, fluorte, bentonite, muddy greenstone, leaf, shale, purple sand and crushed stone, green muddy crag, basalt, gypsum, graphite, carborundum, heat resistance material and some other materials that Moh's hardness is below 9.3 and humidity content below 6%, non-flammable non-explosive minerals' processing.

The working process of the Mainframe is that the motor brings along the central axis to drive through decelerator. The upper part of the axis connects with the roller hanger, the roller Assembly is on the roller hanger through horizontal axis, and forms a swinging pivot. It does revolve around the central axis, at the same time the rollers revolves around the inner round of the grinding ring on account of the centrifugal force, and it self also revolves on account of the friction force. The slope shovel is loaded on the low flange, which is on the lower part of the shovel seat, in the lower part of the roller hanger. The front head is near the low plate of the grinding room, while the back head is in the cuneiform, which separates the roller and ring. In the process of revolving of the shovel and the roller, the Material will be fed into the space between the Trapezium rings and the rollers to grind. The air current which enters the grinding room through the bottom of roller brings the small powder into the Classifier, thus get the fine powder.
