grinding mill

LM series vertical grinding milling machine is a continuous presentation of the material during the grinding process, a large block of material by jaw crusher to the required size, the material sent by the hoist storage hopper, and then by the electromagnetic vibration feeder the unit will even host the quantitative material continuously fed indoors grinding mill. LM series vertical grinding milling machine equipped classifier can improve the accuracy and products of high-density separator impeller at the same speed, the user can change the density of the blade to form the finished material impact on the fineness.

LM Vertical Grinding Mill Working Principle

LM Vertical Grinding Mill working principle is to apply a pressure roller on the material relatively uniformly distributed on the rotary disc is milled. Because of the grinding material layer, you can use the power part of the material broken when splashing, and has low energy consumption characteristics of vertical mill grinding tertiary crushing the binder layer. When the vertical mill work, relatively homogeneous material from the feed device sprinkled on the rotation of the disc, and the disc's acceptance of the roller mill, the material after grinding and grinding material breach section under the effect of centrifugal force gradually overrun disc and by the powerful role of the disc around the circumferential direction of the wind so that the overflow of material along the helical direction of the tube wall and into the working chamber of the upper lift grading machine, large particles fall in the central region of the working chamber of the disc by rolling again. Complex flow field flow throughout the working chamber, pressure, temperature, density different logistics, is a typical composition of the gas-solid flow

LM Vertical Grinding Mill Hot Reason

  • 1. Air inlet, the inlet and the powder outlet location to meet the system requirements
  • 2. Set the necessary seals to ensure that equipment does not enter each bearing dust
  • 3. Lubrication, hydraulic, pneumatic systems, sealed and no leakage
  • 4. Vertical mill bearings at each joint after assembly flexible operation
  • 5. Load operation noise level value does not exceed 90dB (A)
  • 6. Model specifications with vertical grinding mill consumables interchangeable

Cement Production Line Should Now Be Using The Vertical Grinding Mill Or Milling It?

Because without the use of vertical roller mill , grinding rolls for non-contact grinding, greatly improving production efficiency, reduce power consumption, which greatly reduces the cost of production and maintenance costs, is the new cement production line, ultra-fine mineral powder production line ideal choice. Zenith grinding mill principle using material bed grinding material, to overcome the many shortcomings of the ball mill grinding mill mechanism, high grinding efficiency, low power consumption (energy-saving ball mill than 20% to 30%), large drying capacity, allowing large size material into the mill, grinding process is simple, small footprint, low construction costs, low noise, low wear, long life, easy operation. Meanwhile, Zenith LM series vertical grinding mill can also be applied to limestone, kaolin, marble and other production lines, for a market price as the industry grinding device of choice.
