Application of mini pulveriser

The techno wings mini pulverisers are widely used for grinding of dry/wet spices, green chili, fresh ginger, garlic, fresh fruits, and vegetables. These machines can also be used as a fruit finisher. The techno wings mini pulveriser can also be used for the following dry applications like agricultural chemicals, broken biscuits (hi-fat/low fat), custard powder coffee, charcoal, dals, dyes & pigments, fillers, henna leaves, herbs, leaves and roots instant foods insecticides and pesticides, kaolin molding powders, pharmaceuticals, plastics, poultry feed & marine feed, resins, sugar (biscuit grade/icing grade), separates, tea etc

Construction of mini pulveriser

Mini pulveriser is made from cast iron body. Grinding chamber lined with serrated wear plates, which protects the body from wear and tear. Grinding done by a set of swinging four numbers inters changeable and reversible beater on a balanced rotor which is fitted on suitable electric motor's shaft. A screen classifier forms the lower half of the grinding chamber.

Operating principle of mini pulveriser

The flow of material from the feeding hopper is regulating by means of a vertical adjustable slide to suit the load. Rotor with four beaters runs in anti-clockwise direction. The swinging beaters pass just beneath the ratchet teeth liner fitted inside the top half of the crushing chamber, leaving a gap of 3 to 4 mm between the liner teeth and the tips of the rotating beaters. This cuts the material caught between the liner teeth like a sword with a scissors action at a high speed of 5000 rotations per minute.

After the required size reduction, the material will pass through the screen fitted inside the lower discharge end of the grinding chamber. No sieving is required, as the appropriate size screen fitted will not allow coarser material to pass through. The air generated in the crushing chamber forces the powder to pass through the screen fitted at the bottom discharge end of the crushing chamber, into a cotton bag attached to the delivery trough below. The dust is collect through the attached balloon fitted on the discharge end. The top closed end of the balloon may suspend from the roof or a wall of the building. Every half an hour, the balloon should be tap to knock down the dust clogging the pores of the balloon, thus releasing the pressure built-up. The dust falls in the bag below, and thus a dust free operation without wastage of product achieve. (When crushing wet-pulpy materials, the balloon should not be use).

Servicing guidelines of mini pulveriser

Open the cover of chamber all grinding parts clean with a brush in couple of minute and the pulveriser is ready for next grinding. If required, the grinding chamber can also be wash with water. Remove the cotton balloon and the screen, close the cover tightly and start the grinder. Now pour a bucket or two of water into the hopper. The grinding parts will be flushed with the water and cleaned. Continue running the machine for a few more minutes as the draft of the fresh air sucked into the grinder will dry it. When the beater worm out removing and reserved by removing the cur clip lock holding to the rotor pins. When both the edges are worm outs, they sharpened on an emery stone, to use as new. In addition, when completely warn out, replace the equal weight and refitted.
