High Chromium Cast Iron Body Liner on how to increase production and save energy and reduce consumption of cement mills

1. Change the liner waveform
According to the characteristics of the material, the particle size of the in-grinding and the fineness of the out-grinding, the inner diameter and rotation speed of the mill, and the ratio of the grinding balls, the wave shape and peak size of the liner are selected. Compared with the corrugated (wave) lining plate, the trapezoidal (stepped) lining plate throws more grinding balls to increase the height of the wave crest, which can increase the height of the dribbling ball. The tailor-made lining plate can increase the output by 20%. about.

2. Change the grinding ball ratio (gradation)
The ratio of grinding balls is determined according to the characteristics of the material, the particle size of the in-grinding and the fineness of the out-grinding, the inner diameter and speed of the mill, the waveform of the liner, and the material of the grinding ball, which can increase the production by about 10%; The wear resistance of the material is poor, and the small ball is less equipped. According to the size of the ball diameter, the function of the grinding ball is divided into four categories: coarse crushing, fine crushing, coarse grinding and fine grinding.
3. Use grinding balls with low out-of-roundness and high wear resistance
Grinding balls with polygonal out-of-roundness and low crushing rate have high crushing and grinding efficiency; high wear resistance, small diameter grinding balls are not easy to fail, and more small balls can be used to improve grinding efficiency.
