Features of Trapezium Mill

1. Innovative roller and grinding ring design. Comparing with Raymond mill, rollers and grinding ring are designed as multiple steps shape, which can reduce falling speed of material falling in rollers and grinding ring, and prolong grinding time of materials, enhance products' fineness and production capacity.

2. High efficient balance pressure spring. Trapezium mill absorbs advantages of Raymond mill and roller mill, which can connect roller integration with the horizontal spring with pull bar. Generated axial force can reduce loss of main draft and bearings caused by bulk materials' falling into the mill cavity and prolong life span of equipments.

3. Main engine and powder concentrator is connected flexibly, vibration and noise will be reduced by vibration spring and seal tape, and avoid resonance at the same time.

4. High-density, high-precision impeller device.

5. High efficient centrifugal fan. Fans play an important role in the whole rotating process, the trapezium impeller energy saving fans are adopted, which is much more efficient that vertical impeller fans.

6. Comparing with Raymond mill, the patent super pressure trapezium mill will enable convenient, prompt adjustment of clearance between head of the separator and the shell, which can greatly improve fineness of the readymade products.

Application of Trapezium Mill

The trapezium mill is mainly used in metallurgy, construction materials, chemicals, ores, highway construction, hydroelectricity, fire resistant materials, and steel industries to process powder. Those materials such as quartz, feldspar, calcite, talc, barite, fluorite, rare earth, the marble, ceramic, bauxite, iron ore, copper, iron oxide red, zircon sand, slag, cement clinker, activated carbon, dolomite, , granite, garnet, iron oxide yellow, fertilizer, compound fertilizer, fly ash, coal, Ling U.S. sand, chromium oxide green, gold, red mud, clay, kaolin, coke, coal gangue, porcelain clay, kyanite , fluorspar, bentonite, stone, shale, basalt, gypsum, graphite, silicon carbide, thermal insulation materials with Mohs hardness below 9.3 and humidity below 6%, and non-flammable and non-explosive ore materials are suitable for processing.
