Vertical Raw Mill Layer Thickness Control

Factors Affecting Material Thickness

  • 1, the amount of water spray. When the amount of water spray is large, the layer is thick.
  • 2, into the grinding temperature. The temperature is high and the material layer is thin.
  • 3. Feeding amount. The feeding amount is large and the material layer is thick.
  • 4. Grinding pressure. The grinding pressure is large and the material layer is thin.
  • 5. System ventilation. When the air volume is large, the material layer is thin.
  • 6, cycle load rate. When the speed of the classifier is changed or the grinding condition of the Vertical Raw Mill changes, or the material wearability changes, the thickness of the material layer changes, and the cyclic load rate becomes larger. The layer becomes thicker.

Optimum Layer Thickness

Due to instrumentation reasons or equipment wear, changes in material properties, etc., we cannot expect an exact value of the layer thickness control target value. The optimum layer thickness is embodied in the following aspects:

  • 1. The output of the Vertical Raw Mill is high.
  • 2. The Vertical Raw Mill has high power and stability, but the fluctuation is not large.
  • 3. The material layer has small fluctuations.
  • 4, grinding vibration is small.

How To Control The Thickness Of The Layer

  • 1, the appropriate amount of water spray. a. The material layer is thin, and the main motor power can increase the amount of water sprayed. b. The material layer is thin, and it is not advisable to increase the amount of water spray when the main motor power is high. c. The thickness of the material layer can reduce the amount of water spray when the power of the main motor is high. d. The thickness of the material layer should be increased when the power of the main motor is low.
  • 2. Higher grinding pressure. The higher grinding pressure enables the Vertical Raw Mill to achieve higher grinding efficiency, which can reduce the cyclic load and contribute to the stability of the material layer.
  • 3, the appropriate amount of feed. According to the amount of returning material, the feeding amount is adjusted in time, so that the feeding amount and the circulating load rate are always stabilized at the level that can make the Vertical Raw Mill achieve the optimal grinding efficiency.
  • 4, suitable into the wind temperature. According to the water content of raw materials, the inlet air temperature is regulated. The basis is that after determining the certain inlet temperature, if the outlet air temperature decreases and the thickness of the material layer becomes larger, the inlet air temperature should be increased, and vice versa.
  • 5. Appropriate ventilation. Under the premise of ensuring the fineness of the fineness, increasing the ventilation amount is beneficial to reduce the cycle load rate and reduce the thickness of the material layer.
