| We have three types of pulverizers to offer you for the grinding of spices as under :- |
| 1. D. P. Mini pulverizer is a very simple type of pulverizer. The grinding chamber consists of a serrated ratchet liner on top, and screen at the bottom for classification. Feed material is passed into grinding chamber through a hopper manually. The ground power is collected in a through fitted below the screen, depending on the desired fineness, the number of operations could be 2 or 3 in different types of sieves. |
During the grinding process, a small quantity of air is generated, to remove this air a Polyester dust bag is fixed below the through and the other end of the bag is hung at a height, also acting like a dust collector. Our D.P. Mini Pulverizers are exclusively ideal for the grinding of small quantity of spices, especially for high value condiments like, cinnamon, cloves, cardamom, nutmeg, pulses, sugar with a capacity from 5 Kgs. To 60 Kgs. Per hour, more ever this machine is also highly capable of grinding wet and pulpy material, like green/red chilly sauce, fresh ginger garlic paste, and other wet and allied food products. The attached illustrated & informative catalog of D.P. Mini Pulverizer attached over separate following e-mails will give you a thorough idea of the type of equipment manufactured by us. We give here below production figures for the same :- |
| 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. |
| TheD.P. Impact Pulveriser / Pulverizeris 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 ensuringdust 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. |

| The D.P. Micro Pulverisers is a high-speed hammer and screen mill, which accomplishes size reduction by mechanically impacting process material. This method of size reduction is characterized by relative high energy and short residence time, minimizing heat build up during the milling process. |
| Operating Principle |
| The D.P. Micro Pulverizers consists of a rotor assembly fitted with hammers and operates generally at high speeds. A cover fitted with a liner, a retaining screen at the point of mill discharge and a feed screw mechanism whereby the unground material is uniformly fed to the grinding chamber. |
| The grinding action in the D.P. Micro Pulverisers is the impact between rapid moving hammers and particles themselves. The energy of the moving hammers dissipates itself into the particles by virtue of their inertia thus causing size reduction. |
| Applications |
| The D. P. Micro Pulverizers, can be used for a wide range of application e.g. Activated Carbon, Animal Feeds, Carbon Black, Chalk, Cocoa, Starch Dyes, Fine Chemicals, Gram Flour, Kaolin, Pigments, Sugar, etc. |
| Outstanding Features Efficiency and Compactness. Quick and Easy Cleaning. Labour Saving. Long Service Life. Guaranteed Performance. Lowest Cost. |

The D. P. Impact Pulveriser is modified for metal dross separation. The metalic dross to be separated is crushed in the crushing chamber, care is taken during crushing, that the pure metal is not crushed into very fine particles size, as this metal is very difficult to recover. In the crushing chamber, a suitable door is provided for the separated metal to get discharged. The quality of this metal (i. e. percentage of pure metal) is in form of granules and oxides, depend on the percentage of pure metal in the dross. If the dross is of high metal content, then the discharge through the door is of high purity. If the dross is of low metallic content then, with the metal granules there is a small percentage of oxides. This mixed metal with oxides needs to be sieved.
The whizzer classifier obstructs the pure metal granules to pass into the blower, however some particles escape from the whizzer and enter into the blower. This material from the blower is taken to a pre cyclone, to remove all the pure metal granules entering into the cyclone, so the material collected in the cyclone is only oxides. The outlet of the cyclone is connected to a dust collector, so all fine oxides are collected in the dust collector

| 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. |
