Shri Krishna 3 Roller Mills


Shri Krishna Roller mills with integral separator provider an automatic dust free complete system for medium & fine grinding and classification of wide variety of mineral and chemicals as well as simultaneously removing surface moisture from many products while they are being grind.

Principles of Operation

The grinding operation in Shri Krishna Roller Mills is performed on the principal of Attrition and compression, which results due to the centrifugal force generated from the suspended rollers running inside a stationary Bull Ring.

The material to be grind enters the grinding chamber through an automatic feeder and falls on the mills floor. There it is scooped up by steel into the nip space between the rollers and Bull Ring where grinding takes place.

A constant quantity of air is circulated through the mills and system. The air from blower enters the mills through a series of tangential ports round the bases of grinding chamber and sweeps the fine and medium fine material to the classifier above the grinding chamber leaving no grinded material in the chamber and allowing the rollers to work & efficiently crushing coarse material.

The classifier separates grinded materials, and coarse particles return to grinding chamber for further size reduction. Fine materials are carried by air to the cyclone air separators where air and grinded material are separated and collected. The clean air is returned to the blower for close circuit operation.

Dustless Operation:

For providing dustless operation, the mills is operated under negative pressure and is equipped with a Dust Collector system where any surplus air in the circuit is vented and fine dust is collected in dust collector bags.
