1.Host Improved -- The increasing grinding space and force, achieved by heightening roller & ring and enlarging blade, increase production capacity.
2.Reducer Improved -- Compared with past single rotating speed, the modified reducer’s rotating speed can be adjusted optionally as per requirement, production capacity increased by improving grinding force.
3.High Classification Accuracy -- Classifier adopts built-in large taper blade turbine classifier. The outlet fineness can be adjustable from 80-600 mesh.
4.Cyclone Collector Improved -- More effective collecting efficiency is achieved by adopting super large cyclone collector.
5.Air Blower Improved -- It is equipped with high pressure air blower. The wind pressure is doubled and pneumatic conveying ability is improved greatly.
6. High Capacity & Low Power Consumption -- 30%~50% production capacity is improved compared with old model 5R4119.
