5R4128&5R4125 Modified Pendulum Pulverizer

5R4128&5R4125 Modified Pendulum Pulverizer

5R4128&5R4125 modified pendulum pulverizer is mainly used in chemical industry, such as, grinding glass, rubber, pesticides, enamel, paint, phosphate fertilizer, paper. Hardness below seven Moh’s hardness following humidity below 6% non-flammable and explosive materials. For instance: talc, barite, calcite, limestone, manganese ore, iron ore soil, chrome ore, quartz, gypsum, bentonite, etc. The grinded size of 5R4128 is less than 200mesh, and the grinded size of 5R4125 is less than 325mesh.

Product Detail

Product Tags


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.
