LUM Vertical Roller Mill

Vertical mill has two classic models, namely LM series vertical grinding mill and LUM series ultrafine vertical roller mill. Vertical mill is also known as roller mill, ring roller mill, middle-speed mill and so on. Different vertical mill has different number of rolls. The number of rolls impact the fine extent of the final product.

  • [Feed size]:<10 mm
  • [Capacity]:5-18 T/h
  • [Application]:Widely used in ultra-fine milling chemical, metallurgy, non-metallic mineral industries (for more applications, please click on the "free consultation")
  • [Materials]:Mohs hardness below 5, the density of 3.2 or less, compressive strength 150Mpa following, non-flammable mineral, non-corrosive materials brittle granular and powdered materials, such as limestone, calcite, talc, barite, dolomite and other non-metallic minerals.

Material falls on the center of disc through the screw feeder. Through the motor of host drives gear driving disc rotating to make centrifugal force, so that the material uniformly moves around lap. When the material moves through the area of rollers on the disc, the material is rolled by rolls. Bulk material is directly crushed, but smaller particles forms the bed of materialto do inter-particle crushing after squeezed. After being crushed material continue to move the edge of the disc. Then material is taken away by the air entering from the inlet to the selected powder machine grading. Under the role of separator blade, the powder that does not meet the requirements particle need to fall into the disc to be grinded again. But the powder meeting the standards will enter the pulse dust with the air through separator to be collected. The powder collected is final product. Iron and other impurities mixed in material, because of the difficulty of grinding and big gravity, when move through edge of the disc, can not be taken away by the air flow, fall into the inferior vena of mill, was sent to Scum outlet by scraper plate and discharged outside the host.

  • 1. Abrasive materials under variable pressure;
  • 2. Small amount of maintenance, wear parts, easy maintenance;
  • 3. High yield in every machine and every hour, power consumption, and low energy consumption;
  • 4. Static and dynamic classifier regulate product quality, with higher grinding efficiency;
  • 5. Simple process, preheating, grinding, upgrade in one, short process, small footprint;
  • 6. Strong self-protection, with a gear lubrication oil station, hydraulic station, roller lubrication, sprinklers and other auxiliary facilities.
