Double-Spiral Stage Classification Liners
Achievement:
Listed as promotion project of National Ninth Five-year plan for its scientific and technological achievement in building material industry.
Characteristics:
They are applicable to mill fine grinding chambers. Due to the spiral arrangement of polygonous cross sections and loose and close arrangement of inclined edges, the double spirals are formed. This makes cylpebs a good positive classifying effect, increasing grinding efficiency. It is especially good for upgrading the specific area of cement.
