SCM Ultrafine Mill

SCM Ultrafine Grinding Mill is a new superfine powder (325-2500 mesh) production equipment developed through accumulating years of experience in grinding mill production, absorbing Swedish advanced machine manufacturing technology, and undergoing many years of tests and improvements. The SCM Ultrafine Grinding Mill is the result of combination of advanced Chinese and Swedish technologies. Meanwhile, it symbolizes the new development and new science in the grinding world.

Product Features: Ultrafine powder, wide applications, excellent environmental effect
Input Size: 0-20mm
Capacity: 0.5-25TPH
Material: Limestone, calcite, dolomite, petroleum coal, gypsum, barite, marble, talc, coal powder, etc.
  • No Rolling Bearing & Screw In Grinding Chamber

    There is no rolling bearing and screw inside the chamber of SCM Ultrafine Grinding Mill, so users are free from worries about damages on bearing or its sealing parts, and there is no machine damage problem caused by loose screws. The lubricating device is installed outside of the main shaft, so that lubrication without shutdown can be realized externally, and the production can be continued for 24h.

  • Adjustable Fineness Between 325-2500meshes

    SCM Ultrafine Grinding Mill’s cage-type powder selector adopts German technologies, which effectively increases the precision of powder separation. In addition, multi-head cage-type powder selector can be configured according to the users’ requirements on yield, fineness and sieving rate. The product fineness can be adjusted between 325-2500 meshes, and the screening rate can achieve d97≤5μm once.

  • Higher Yielding, Lower Energy Consumption

    Newly designed grinding curves of grinding roller and grinding ring further enhance the grinding efficiency of SCM Ultrafine Grinding Mill. With the same fineness and power, the production capacity is 40% higher than that of jet grinding mill and stirred grinding mill, and the yield is twice as large as that of ball grinding mill. However, the system energy consumption is only 30% of the jet grinding mill.

Working Principle

The material enters into the host, and falls down the central of bulk material disk. Due to the high speed rotary of turntable, the materials move to the round, and fall into the loop between grinding roller and grinding ring. The materials are grinded. After the first layer of grinding, the materials will fall into the lower layer for grinding again. Afterwards, the materials are taken into the powder selecting machine by fan airflow. The material that does not meet the size requirement, falls into the host to grinding again. The material that meets the size requirement, enters into the cyclone powder collector. The materials do separation and collection. The finished product powder is discharged from the discharging device.
