Trapezium Mill

　　OBM series high pressure European grinding machine is widely used in metallurgy, building materials, chemical and other industries product grinding processing, is our company experts absorb the latest European grinding technology combined with years of domestic experience research and development of advanced industrial grinding equipment, is the preferred alternative to the traditional grinding machine. Suitable for limestone, calcite, marble, talc, barite, gypsum, lime, heavy calcium, attapulgite, dolomite, coal, feldspar, quartz, graphite, coal gangue, fluorite and other MoHs hardness below 8, humidity at 8% of all kinds of non-flammable and explosive mining materials processing.

      1. Compared with other grinding machines, the output is increased by 25%-35% under the same power, and the contact area of the grinding roller and the grinding ring on the magnetic pressure of the material is large, and the grinding chamber space is also large, thus the output is greatly improved.

　　2.OBM mill finished products have a wide range of particle size, the maximum diameter can reach 0.631 mm (30 mesh), the particle size can generally reach 0.033 mm (425 mesh), a small number of materials can reach 0.013 mm (1000
mesh)

　　3. The dust removal effect of OBM mill fully meets the national dust emission standards.

　　4.OBM mill analysis machine is easy to adjust.

　　5.OBM mill grinding device adopts overlapping multi-stage sealing, good sealing performance.

　　The roller device of the traditional R-type pendulum mill, the pendulum shaft is placed horizontally, the roller device is tilted when swinging, and there is several degrees of Angle between the roller and the grinding ring face, which affects the grinding efficiency. OBM is a pendant device thrown out laterally, when the central shaft of the main machine rotates to drive the centrifugal roller device

　　Compared with the two methods, the centrifugal force of the pendulum device increases by nearly 35%, which intensifies the crushing energy of the powder, so that the output is also increased by 35%. In addition, the pendulum device makes parallel contact between the grinding roller and the grinding ring, which is more conducive to the uniform wear of the powder crushing and grinding area, thus extending the life of the wear-resistant parts.
