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 :-

Size of Machine	H.P. Required	Production Per Hour Approximately
D.P.M. - 6 Mini Pulverizer	2 H.P.	8 - 12 Kgs.
D.P.M. - 7 Mini Pulverizer	3 H.P.	15 - 20 Kgs.
D.P.M. - 8 Mini Pulverizer	5 H.P.	20 - 25 Kgs.
D.P.M. - 12 Mini Pulverizer	10 H.P.	55 - 60 Kgs.

2- Our D.P. Hammer Mill (Screen type Machine) is more efficient than compared to the Mini Pulverizer, with better grinding efficiency. The grinding chamber consists of a serrated liner on top and screen at the bottom, a blower is fitted to suck the ground powder, below the screen driven on the same shaft. At times due to higher oil content in spices, there are chances of the screen getting clogged with spices, thus chocking the grinding chamber. The material passes through the blower and gets discharged through the cyclone through a one way valve. The air generated in the grinding chamber passes out through the cyclone outlet on top. A Polyester dust bag can be fitted above the cyclone working like a dust collector, or we can offer you a totally enclosed dust collector (manually shaken type) or a pulse air type dust collector, the choice we however leave it to your kind decision. The attached illustrated catalog will also brief you about the type of machine manufactured by us.

Our D.P. Hammer Mills are exclusively meant for the grinding of Chillies, Coriander, Dry ginger, Black Pepper, Turmeric and Curry powders, on a large scale basis. These spices are ground in a two / three stage operation, depending on the fineness desired, i.e. The breaking of the spice in a large hole screen for the first operation, and the subsequent fine grinding done in a fine hole screen for the second and third operation. We give here below production figures for the same.

Size of Machine	H.P. Required	Blower H.P.	Production Per 8 Hours Approximately
DPHM -10 Hammer Mill	10 H.P.	-	350 - 400 Kgs.
DPHM -20 Hammer Mill	20 H.P.	-	700 - 800 Kgs.
DPHM -40 Hammer Mill	40 H.P.	-	1400 - 1600 Kgs.
DPHM -50 Hammer Mill	50 H.P.	50 H.P. 7.5	2500 - 2750 Kgs.
DPHM -80 Hammer Mill	80 H.P.	10	3600 - 4000 Kgs.

3- Our D.P. Impact Pulverizer (screen less type) is for the exclusive grinding of Turmeric in one operation. We give here below the production figures for the same

Size of Machine	H.P. Required	Production Per 8 Hours Approximately
D.P. - 20 Impact Pulverizer	20 H. P.	700 - 800 Kgs.
D.P. - 25 Impact Pulverizer	40 H.P.	1800 - 2000 Kgs.
D.P. - 32 Impact Pulverizer	50 H.P.	2800 - 3000 Kgs.
D.P. - 42 Impact Pulverizer	100 H.P.	7000 - 7200 Kgs.

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

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.

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.

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.

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.

D.P. 25 Impact Pulveriser with Totally Enclosed Dust Collector For Metalic Dross Separation

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
