Vertical Roller MillIntroduce

 Vertical grinding machine is a kind of crushing, grinding, powder selection, drying, material conveying five functions in one integrated large grinding equipment, with a concentrated process, small footprint, less investment, high efficiency, energy saving, environmental protection and other characteristics.


Vertical Roller MillAdvantage

  1. Integrated design, one machine multi-purpose

  Set crushing, drying, grinding, grading and conveying in one, compact layout, small footprint; The main attack non-metallic ore, coal and slag three major

  In the field, the process is mature, which can be applied to the grinding of raw materials and clinker, and can also be used as pre-grinding equipment to greatly increase production and save energy for subsequent mills.

  2. Take more measures to save operating costs

  The mill roller directly crushers the ground material on the mill disc to reduce energy consumption; The hot air directly contacts the material in the mill, and the drying ability is strong, saving one drying machine

  Computer; The roller sleeve is used to avoid direct contact between the roller and the grinding disc and reduce wear; The roller sleeve can be used on the reverse side, and the service life is doubled.

  3. Double high efficiency and precision

  The grinding force can be increased by means of hydraulic pressurization, ,so as to increase the output and improve the grinding efficiency. Depending on the granularity of the finished product

  The separator adopts the cage separator and the cone rotor separator respectively, and the powder selection accuracy is high.

  4. Low dust and noise pollution

  The whole machine works under seal and negative pressure, no dust overflow; With a limit device to avoid damaging impact and vibration noise; Transmission system adoption

  Planetary gear reducer, low noise.

Vertical Roller MillWorking Principle

  When the vertical mill is working normally, the motor drives the mill disk to rotate through the reducer, and the material falls in the center of the mill through the air lock feeder from the feed port, while the hot air enters the mill from the air inlet. With the rotation of the mill disk, the material moves to the edge of the mill disk under the action of centrifugal force, and is crushed by the grinding roller when it passes through the ring groove on the mill disk. The crushed material is carried by the high-speed air flow of the wind ring on the edge of the mill disk, and the large particles fall directly onto the mill disk for re-grinding. When the material in the air flow passes through the upper separator, under the action of the rotating rotor, the material is crushed. The coarse powder falls from the cone to the mill plate for re-grinding, and the qualified fine powder comes out of the mill with the air flow and is collected by the dust collection device, which is the product. The material containing moisture is dried in the contact process with the hot air flow. By adjusting the hot air temperature, the material with different humidity can meet the requirements and achieve the required product moisture. By adjusting the separator, the required thickness of different products can be achieved.
