Size Reduction Equipments

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.
Jas Enterprises a pioneer in pulverising machinery manufacturers in India for the last 20 years, and has credentials for exporting many Pulverising machinery, Micro Pulveriser, Dry & wet pulverizer, Wet Pulveriser, masala mill, Pounding machines, Impact Pulveriser, Multi chamber Pulveriser, Hammer mill, Hammer mill with bottom discharge, Auto suction hammer mill, Mini Pulveriser, Water jacketed mini Pulveriser, Daliya Pulveriser, Black pepper dal machine, burr mill ( disc Pulveriser ) to many countries.

Construction of micro pulveriser

Micro 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 micro pulveriser

The flow of material from the feeding hopper of micro pulveriser 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 2800 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 micro 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.
