The D.P. Impact Pulveriser / Pulverizer is a versatile grinding unit of heavy and rugged construction and built for continuous operation day after day. The unit is especially designed for the medium fine, and fine size reduction.

The industrial pulverizer meet most capacity requirements and lend themselves to a wide degree of adjustments with fineness of the finished product ranging from about 60 mesh to bulk passing through 325 mesh, depending on a considerable extent to the particular material being handled. Unlike an ordinary hammer mill, it has no screens to break, wear out or clog in the crushing chamber. The D. P. Impact Pulverizers combines grinding, classifying and conveying all in one single unit.

Operating Principle of Impact Pulveriser

The D.P. Impact Pulveriser consists of an encased rotor carrying swing hammers, whizzer classifier for fineness regulation, and Blower Fan mounted on a solid shaft. Raw material to be pulverised enters the crushing chamber through the hopper and automatic rotary feeder. The impact of the hammer 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 over size particles are rejected by the classifier and returns 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 dust Free operation and no loss of ground powder.

Application of Impact Pulveriser

The D. P. Impact Pulverizer and Industrial Pulverizer 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.

Operating Principle

Referring to the schematics below, most of the processing air or gas enters through the bottom section of the mill. Up to 30% of the total airflow can be introduced with the feed material. Concurrent with this constant mass flow of gas, feed material is introduced to the mill ideally in a constant mass flow manner.

For most applications, material is introduced to the tip of the rotating hammers through a port opening at the side of the mill. Feed material can be either pneumatically conveyed or screw fed. The rotating hammers attached to the impact rotor disc serve to fracture the process material.

A serrated liner mounted on the periphery of the grinding chamber in the hammer path serves to improve grinding efficiency by preventing particles from accelerating to the speed of the hammers thereby increasing the relative speed difference.
The primary airflow passing through the narrow annular gap formed in between the liner and impact rotor disc in conjunction with the fanning action of the hammers transports the material to the top of the mill. A dispersion ring then directs the material downward toward the classifier. Baffles welded to a shroud ring straighten the flow of material and air so that particle vortexing at the dispersion ring area is avoided.

The shroud assembly effectively separates the grinding zone from the classification zone as well as providing a defined path for the material and air to flow through.
