LUM Ultrafine Vertical Roller Mill

LUM Series Ultrafine Vertical Roller Mill adopts GCM Mechanical abundant experience in producing vertical grinding mill and the latest technology from Taiwan &Germany. It sets grinding, drying, classifying and transportation as a whole and has been become the Mainstream equipment in ultrafine grinding industry.

Features

  • LUM is of little dust and noise, achieving Environmental Protection Request, it is quite environmentally friendly
  • Utilize advanced working principle and reduce the grinding time, as a result, the final products has little iron and the whiteness and purity are raised.
  • LUM has excellent grinding-efficiency for the special design of roller shell and grinding plate curve.
  • Low investment cost: LUM use PLC/DCS automatic control system, well save the cost of operators.

Application

LUM Series Ultrafine Vertical Roller Mills are widely used in grinding non-flammable and non-explosive materials under 9.3(the Moh's hardness), such as grinding quartz, feldspar, calcite, talcum, barite, fluorite, iron ore, copper ore quartz, slag, cement clinker, zircon sand, fly ash and carborundum, coal, etc.
