D.P. Pulverisers manufacture a large variety of Impact Crushers to virtually any size reduction job. The extremely rugged construction of Impact Crushers ensures a long life with minimum maintenance easy to install and economical to run. The shell of Impact Crusher is lined throughout with MS, Cast Iron or Manganese Steel, according to the size of Impact Crusher and duty required. We can provide a Impact Crusher to reduce almost any material to the size required.   Operating Principle of Impact Crusher   Material is fed in Impact Crusher from the periphery through a hopper into the grinding chamber to minimize air pressure, greatly reducing dust problems. For some material suitable ventilation is recommended by introducing air on the discharge side of the crusher, this will prevent a dusty atmosphere at the inlet of Impact Crusher. The swinging hammers in Impact Crushers crush the materials along the stationery liners before discharging through a perforated screen at the bottom; replaceable bar type screen is available for specific application. Combination of hammer style, liner plates and sieve inserts offer almost unlimited possibilities to cater user needs from an Impact Crusher.   Applications of Impact Crusher   The Impact Crushers are used for crushing or shredding of diverse materials such as: Limestone, Glass, Coal and Lignite, Clay, Sand, Phosphate, Rock, Fertilizer, Aluminium Oxide, Slags, Coke, Silica, Bauxite, Dolomite, Grain, Barytes, etc.   Outstanding Features of Impact Crusher Impact Crusher is specifically designed to withstand the abuse of grinding of abrasive materials. Heavy duty, replaceable, abrasion resistance wears plates in mill top. Heavy duty hard faced or heat treated hammers. Heavy duty rotor assembly. Rugged bar screen or thick perforated metal screens to size materials. Impact Crusher is opted with Dust-tight or water-tight construction.

The D.P. Ribbon Blenders are based on a proven agitator construction that provides a triple mixing action thus ensuring fast efficient blending. The dimensions and configuration of the ribbons in Ribbon Blender are carefully balanced to provide a movement of material within the container that avoids dead spots and gives rapid product discharge. The design of the D. P. Ribbon Blenders can incorporate features required for a customer's product or process such as: wear resistance, corrosive resistance, vacuum filling and discharge arrangements, special shaft seals, heating/cooling jackets. Ribbon Blenders are available in sizes 50-5000 liters in S. S. 304, S.S. 316 & M.S. construction.    Triple Mixing Action of Ribbon Blender As the agitator rotates in Ribbon Blender, the material is tumbled and carried radially around the inside of the blender. The pitch of the outer ribbon moves the material towards the discharge opening. The inner ribbon which has a opposing pitch moves the material away from the discharge opening.

Air Classifying Mill  is used for separating dry materials into different particle size fractions by their size, mass or shape also modify a particle size distribution. We have established a note worthy status among the Air Classifying Mill Manufacturers in India. We bring for the clients Air Classifying Mill of exceptional quality at cost-effective price.    Known For : Resistance to wear and tear Sturdy build Easy installation Compactness Simple design Low maintenance Cost-efficiency Superior quality 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.

Pneumatic Conveying System (Dilute Phase Conveying)   Pneumatic Conveying has decisive advantages in conveying dusty products over mechanical conveying, low space requirements and low maintenance. Also it is flexible in construction, can be easily automated, provides dustless conveying without loss of material and is thus also safe for products hazardous to health. A conveyable product is transported through a pipe by using a certain quality of gas [air or nitrogen]. The product particles are freely moving with the high gas velocity and a low product to air ratio. The different types of Pneumatic Conveyors are   A) Vacuum Conveying System : D. P. Vacuum Conveying System works on negative pressure for conveying the material from one or number of pickup points to one discharge point. This system is best suitable for providing dust free conditions around inlet.   B) Pressure Conveying System : D. P. Pressure Conveying System conveys bulk material by air under pressure. This system offers advantages of conveying material from one place to one or number discharge points.   C) Combined Vacuum-Pressure Conveying Systems : D. P. Combined Vacuum- Pressure Conveying System conveys the material from various pick-up points to various discharge points, it is also used where vacuum pick-up and pressure delivery is required.   D) Closed Loop Conveying System : D. P. Closed Loop Conveying Systems are designed for handling, explosives and hazardous materials. The conveying gas is usually nitrogen for explosive materials, and dry air is used for handling hygroscopic materials.

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 Pulverisers 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 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.   Outstanding Features of Impact Pulveriser   * Easy starting. * Cold & silent running * Dust free operations * Robust Construction                                               * Low Specific Power Consumption * Automatic Feeding * Durable Long Life * Guaranteed Grinding Efficiency
