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.

The D.P. Micro Pulveriser 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 Pulverizer 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 Pulveriser 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.

D. P. MINI PULVERISER The D. P. Mini Pulveriser Comprises of a heavy duty Mild Steel/Stainless Steel body, which comprises of a feeding hopper, with a feed regulator slide. The pulveriser body is inlaid with a delivery trough attached at the bottom, with a delivery trough attached at the discharged end. The rotor & beater are mounted on shaft, running in a ball bearing housing at a speed of 4500-6000 R.P.M. The whole unit is mounted on a strong steel channel stand.

The D. P. Hammer Mill comprises of a heavy duty Mild Steel fabricated body (alternatively stainless steel construction can be provided in hammer mill wherever necessary). The grinding chamber of hammer mill is lined with serrated wear plates, which protects the body from wear and tear. A balanced rotor in hammer mill with a set of Swing Hammers accelerates the grinding process. The screen classifier forms the lower half of the grinding chamber of hammer mill. The blower in hammer mill is driven on a separate shaft with the help of a 'v' belt adjustable driven from the rotor shaft.

D. P. Universal Mill The D.P. Universal Mills find applications in fine and ultra fine size reduction of soft to medium hard products, with an upper hardness limit between 3 and 4 on the Mohs hardness scale for minerals. The D.P. Universal Mill casing and doors that can be closed by screwing down a hand wheel. At the rear side of the case there is a bearing body with the drive shaft that runs on rolling bearing and carries the interchangeable crushing elements.

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.

The D.P. Vibro Sifter is a circular highly efficient gyratory screen with adjustable multiplane three component mechanical vibration. The heart of Vibro Sifter is the robust specially made vibrator motor which is designed for long trouble free continuous operation. The vibrator motor has double extended shaft fitted at each end with variable eccentric weight. Motor is rigidly mounted on circular vibrating table on rugged springs. Number of interchangeable spacing frames having discharge outlets along with tensions rings fitted with screens cloth can be mounted one on top of the other, on the Vibrating table with the help of clamp rings. D.P. Vibro Sifter is the most efficient screening machine for any dry and wet sieving application.

Applications of Dust Collectors :
Cartridge type dust Collectors are Cartridge filters with automatic cartridge cleaning by compressed air pulses. Dust Collectors serves for the dry separation of dust from exhaust air in areas like:
*  Plastic Processing Industries
*  Pharmaceutical Industries
*  Food processing Industries
*  Cement and Mineral Industries
*  Powder Coating Industries
*  Pneumatic transport of solids
*  Air conditioning Plants

The D. P. Rotary Air Valves have been designed for absolute universal use. They are ideally suited to control delivery or discharge of powders or palletized products to and from hoppers,

bag filters and centrifugal separators. Rotary Air Valve's strong and compact construction makes it a simple matter to access the internal working parts.

Size150-175-200-250-300 & 350 mm
Standard Design features of Rotary Air Valve
*  Rotor with beveled tips for powder.
*  Connection with plug for bearing purging.
*  Sealing of shaft by means of radial lip seals

DP Pulveriser industries manufactures 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.

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 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.

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.
