Shri Krishna 3 Roller Mills
Introduction
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.
