HAMMER MILL
Feed Material passesthrough a wide feed
hopper into the grinding
chamber. The swinging hammers, in
the rotating hammer rotor,crush materials at the
stationery liners before
driving them trough ascreen.
The method of operationis impact grinding.

IMPACT PULVERIZER
The equipment is suitablefor medium hard
minerals, chemicals, bulk
drugs, coal, paints, dyes
and pigments, herbs, seed
Application In:
Guar flour, tamarind
kernel powder and their
derivatives. Cellulose and
starch derivatives, to grindpulses and cereals,chemicals, feed and
minerals.Monday, August 08, 2011 12PULVERIZERS

ROLLER MILL Some process need only crushing
of the material
Two hardened rolls rotate towardseach other.
They are kept nearer to each otherby means of either mechanicaldevices or with hydraulic system.
This system helps to create thepressure on the rolls and makesthe crushing possible.
The larger particle of mass, cereals,
pulses is pushed between the rollsuniformly spread and withcontinuous rate through a separatedevice.

PIN MILL
Pin Mill is designed for finer mesh grinding of
different materials, which are heated during
grinding.
The RPM of machine is varying from 2000 to
5000 depending on material to be pulverized.
The output mesh size is also variable from
material to material.
This is an ideal solution for size reduction for
foodstuff.
Uniform output & easy to operate and
maintain are the distinctive features of Pin
Mill.
