LUM Series Ultrafine Vertical Roller Mill

LUM Series Ultrafine Vertical Roller Mill

Vertical mill or vertical roller mill is a kind of roller mill, according to the requirements can be furnished with 2, 3 or 4 roller. Each roller, it is composed of a fixed arm, installation of the rocker arm bracket, and the composition of the hydraulic system the power unit of grinding. This power unit is a one-piece or a standard component.

Advantages

Vertical roller mill can be decorated around the millstone two component, part three or four components. Low compared to other mill noise. The unit energy consumption is low. From control to stop, vibration is very small. Adaptable. Cover an area of an area small, easy adjustment. Excellent dry grinding ability. Easy maintenance (do not have to dismantle grinding machine can replace the wear parts). But for grinding various materials. When the equipment is the smallest model to ensure production to produce 35 tons per hour, the largest model ensure output can reach 557 tons per hour, according to the different production needs of customers and set.

Features

  • 1. On the principle of grinding material layer, the material stay in the grinding time is short, reduce duplication of grinding. Iron content is few, less in finished products used for grinding white or transparent materials, high whiteness and clarity of the product.
  • 2. Specially specially designed for the realization of the superfine grinding principle of roller shell and plate grinding curve, used for super fine powder grinding, easier than ordinary vertical mill to form material layer, makes the mill to a grinding the desired fineness (0.045 0.02 mm).
  • 3. The principle of using multiple classifier, and each rotor can be frequency control of motor speed, the grinding fineness of product within the scope of the selected all can achieve, don't need a second grade of air separation, without the presence of low grade material.
  • 4. In the final product fineness of up to 70% less than 2 microns, the final product of the fineness of 325 low residual material, but can be by secondary classification get more fine products.
  • 5. Main engine revolution speed adopts frequency control of motor speed, which has been widely applied materials.
  • 6. As a result of superfine grinding and several rounds of choosing powder principle, in the production of products of the same fineness grade, than ordinary mill save energy consumption by 30% to 50%, excellent economic benefit.
  • 7. PLC/DCS automatic control roller pressure control method, precise controlling the grinding pressure, without manual operation.
  • 8. Roller lubrication using separate lubrication station, and a single roller loop adopts double pump, pump suction work mode at the same time, even given sufficient lubrication and cooling roller bearing, roller bearing and can guarantee indoor won't because too much oil and cause leakage.
  • 9. Because of the work roller is not direct contact with mill, and the roller and plate made of high-quality sheet metal so prolong the service life, less wear.
  • 10. Full automatic control, simple operation, equipped with remote control function.
  • 11. Equipped with prevent roller set and mill lining board of direct contact with the mechanical limit device and electronic limit device, avoid the destructive impact and violent vibration.
  • 12. The roller can turn out to casing outside for maintenance, convenient and quick replacement of roller cover, liner, reduce outage losses.
  • 13. Little vibration, low noise, whole sealing equipment, system work under the negative pressure, no dust spillover, clean environment, and can meet the national environmental protection requirements.
