PULVERISER (Fineness upto
43 Micron) 
SINGHASINI
Pulveriser’s are impact type, high speed, air swept, swing
hammer type, multipurpose grinding mills capable of grinding
soft to medium hard minerals & chemicals upto the
hardness of 2.5 - 3.0 Mohs. The main mill is supplied
with Automatic Feeder, High Efficiency Cyclone Air Separator
& Dust Collector. The material of construction of
internal parts of Pulveriser main mill, cyclone air separator
& dust collector varies as per individual requirement.
The Pulveriser is supplied with Digital (Automatic) Feed
Controller for maximum feeding.
The Pulveriser is supplied with Reverse jet
Pulse air type dust collector or Totally enclosed Manual
shaking type dust collector or with open type static tubular
dust collector. Heat sensitive materials like Urea,
B.H.C., Lindane which have low melting point or
materials like Dyes, Pigments, Kattha etc etc.. which
have a tendancy to change color during grinding may also
be grinded easily with our open circuit grinding system.
Given below is the table indicating the pulverising capacity
on average basis however the capacity figures will vary
from case to case depending upon several factors. These
figures are meant for guidance only.

PNEUMATIC
CONVEYORS
SINGHASINI
Vacuum Conveying System works on negative pressure for
conveying the material from one or number of pickup
points to one discharge point. This system is best suitable
for providing dust free conditions around inlet. The system
is composed of pick-up nozzle, divertor valve, discharge
lock, exhauster & piping.
CENTRIFUGAL
BLOWER
Centrifugal Blowers are tailor made and sizes depend on
individual requirement, should you require any information
please feel free to get in touch with us.

Steel
Fabricated welded construction braced with steel flats
and angles. Split casing can be provided for large
sizes. Inspection door and drain plug can be provided. |
| IMPELLER |
Impeller
can be made in Light , Medium and Heavy construction
Class I , II and III. Steel or Cast Iron Hub will
be Welded, Bolted or Riveted. Impeller will be Statically
and Dynamically Balanced . |
| SHAFT |
Shaft
are of EN - 8 / SS316 / SS304 properly sized to keep
away from critical speed. |
| BEARING
LIFE |
Bearings
are designed for long life . This life can be attained
when properly lubricated, kept clean, tensioning belts
correctly and keeping Impeller clean and balanced.
Smaller ‘V’ Pulleys and improper belt tensions reduces
the life considerably. Proper care and Lubrication
increases the life beyond this. |
| VIBRATIONS |
Vibration
isolators and flexible connections at inlet and outlet
can minimize transmission of vibration and noise to
building structure and ducts . |
PULSE
AIR DUST COLLECTOR
SINGHASINI
Bag Filters use the well proven air pulse jet cleaning
system . The Filter 
casing has tubular filter sleeves, supported on wire
cage . Dirty gas is cleaned by dust particles clinging
/ stopping on the filter media surface . Clean gas flows
on through the filter sleeve and out from the top of filter
mounting tube sheet . These Bag filters when used can
arrest particles down to 1 micron in size with fairly
good collection efficiency .
The Tubular Filter Sleeves are neatly grouped
in row of multiple elements . While the filters remain
on service , through an auto time sequencing system they
are back washed by a strong pulse of compressed air which
shakes loose the accumulated dirt particles . The dust
falls to the collection hopper and is out through Air
Lock Valve .
We
also supply special Bag Filters to handle potentially
explosive materials by incorporating Explosion relief
valves and using special Anti-Static Filter Media and
mounting accessories . For continuous duty only compressed
Air / Gas is required besides few Watts control power
.
Reverse
Jet Pulse Air Dust Bag Filters are tailor made and sizes
depend on individual requirement , should you require
any information please feel free to get in touch with
us .
