Vertical Roller Mill

LM series vertical milling machine called roller mill, vertical roller mill, with LM-1500, LM-1700, LM-1900, LM-2200 and so on dozens of models, is SBM to solve the low ore milling yield, higher energy consumption technical problems, the absorption of the European advanced technology combined with years of SBM design and manufacture of advanced mill concept and market demand, after years of painstaking design of improved large-scale grinding equipment.

Vertical roller mill processing materials are mainly limestone, calcite, bentonite, gypsum, coal, cement, etc., the use of reasonable and reliable structural design, with advanced technological process, set drying, grinding, separator, upgrade in one, especially in a large flour grinding process, fully meet customer demand, the main technical, economic indicators have reached the international advanced level.

Vertical roller mill used in metallurgy, electric power, cement, power plant desulfurization, slag utilization industry, cement production of vertical raw mill, vertical mill non-metallic minerals.

LM Vertical Roller Mill Features

  • 1. More separator structure, adapt to a wide range. LM vertical roller mill according to different materials, different fineness requirements, the choice of the form of the above two structures separator. At the same time separator (separator) are used frequency control, and therefore a uniform particle size distribution, product fineness is easy to adjust.
  • 2. Advanced and reliable transmission system. Vertical roller mill gear from the main motor, coupling, reducer machine. Reducer with new spiral bevel gear plus planetary gear transmission structure, strong to wear babbitt thrust watts can carry a greater load pressure, improve operating life.
  • 3. Equipped with automatic electronic control system. Vertical roller mill equipped with advanced electronic control system, enabling PLC control, centralized control and DCS control system, oil pressure, oil temperature automatic protection system, so that a full set of equipment safe and reliable, to meet different customer needs.
  • 4. Hydraulics mature and reliable and easy maintenance. Hydraulic control system and control the force applied, with the grindability of the material change automatically adjust the pressure so that the mill always maintain the best condition, both to reduce the consumption of wasted effort, and extended the roller sleeve, lining life.

LM Vertical Roller Mill Working Principle

Rotating disc driven by the main motor reducer, while hot air from the air inlet into the body of the mill stand, the material falls through the inlet central disc, the centrifugal force, the material from the disc center to move to the edge evenly through the powder on the disc when the roller track area by rolling mill rolls, large pieces of crushed material directly after the formation of fine-grained material is squeezed between the bed were crushed grains, refined into the collector at high efficiency dynamic separator effect.
