Operating Principle of Impact Pulverizer
The Impact Pulverizer consists of an encased Rotor carrying swing hammers, whizzer classifier for fineness regulation and pressure gradient creator mounted on a solid shaft. Raw material to be pulverized enters the crushing chamber through the hopper or the automatic rotary feeder. The impact of the hammers on the feed material against the liner plates reduces it into fine powder. The ground material is carried towards the whizzer classifier for classification and the oversize particles are rejected by the classifier and returned to the crushing chamber for further grinding. The classified material is then conveyed into the Cyclone for collection and bagging. A dust collector is provided in the system for ensuring dustless operation and for no loss of ground powder.
Typical Application of Impact Pulverizer
The Techno Wings Impact Pulverizers are used for a wide range of application e.g. Agricultural, Chemicals, Carbon & Graphite, Coal, Coke, Coconut Shell & Wood Saw Dust, Clay, Dye Stuff & Pigments, Detergents, Ferro Alloys Fertilizers, Fillers, Food Products, Herbs & Spices, Insecticides and Pesticides, Katha, Marine feeds, Minerals, Plastics, Pharmaceuticals, Resins, etc.
