 ROTARY
DRYER |
 SINGHASINI
Rotary Dryer operated at almost atmospheric pressure consists of a M.S.Cylindrical shell,
ranging in length from four to ten times its diameter, into which the wet charge is fed
continuously at one end and is discharged at the other, the movement of the material being
due usually to the combined effect of inclination of the shell to the horizontal and
the action of internal lifting flights during the rotation of the shell. The latter
is usually provided with machined girth rings supported on suitable designed
bearings. Rotation of the shell is secured by the action of suitable gearing. Hot
air produced from Hot Air Generator (Direct or Indirect ) is injected into the dryer to
achieve the required dryness of the material . The discharge end of the Rotary Dryer
consists of sealing arrangement , Cyclone and Dust Collector.Rotary Dryers are tailor made Dryers and sizes depend on individual requirement, should you require any information please feel free to get in touch with us. |

Rotary Kiln operated at almost atmospheric pressure consists of a M.S.Cylindrical shell,
ranging in length from four to ten times its diameter, into which the charge is fed

is usually provided with machined girth rings supported on suitable designed
bearings. Rotation of the shell is secured by the action of suitable gearing.
Materials like Gypsum , Activated Carbon , Calcium Carbonate etc are calcined in Kilns .
The temperatures may be as high as 800 - 900 Deg C , refractory lining is provided in
order to achieve high thermal efficiency .Rotary Kilns are tailor made equipment's and sizes depend on individual requirement, should you require any information please feel free to get in touch with us. |

SINGHASINI Flash Dryer in
its simplest form of mechanical design, is merely a Hot Air Conveyor into which solids, if
reasonably free flowing, may be dropped. The material then gets dispersed thus
exposing maximum surface to the drying process. This leads to a very rapid drying
rate and the time required is in seconds - not in minutes or hours. Due to the short
exposure time and rapid evaporation of water, even though high temperature is employed,
the material remains at wet bulb temperature (W.B.T.) until all traces of surface moisture
are removed. Thus it is possible to employ high inlet temperature may be up to 700
Deg.C, without affecting the quality of the material which may even be a heat senstive
one.
drying alone without Disintegration or
Pulverisation could be employed. Fig.1 illustrates the system consisting of
Automatic Feeder, Ventury type gas Conveyors System into the thread of which material is
fed, and a Cyclone Separator is installed to separate the fines. It also requires
suitable type of heater.
and the Disintegrator along with a
Cyclone Separator. The disintegration is accomplished in a SINGHASINI
Cage Mill/Hammer Mill. Depending upon a specific requirement a conditioner or dust
collector may or may not be included in the system.
which Hot Air is
introduced. This system could easily be adopted with advantage and economy if the
end product required is in the form of fine powder. This replaces the system of
pre-drying if done in Tunnel, Rotary or Tray Dryers. Similarly as in the case of
Flash Drying cum Disintegration, a Conditioner and Dust Collector may or may not be
required with the Drying cum Pulverisation system.
SINGHASINI Rotary Vacuum Dryer offers a clean, simple and very effective
method of drying wet cake, powder and even the slurry. The drying is under vacuum
and hence it is possible to dry heat sensitive materials at temperatures well below 100°C
without suffering the problem associated with very long drying periods. Valuable
organic solvents can also be conveniently condensed and recovered. Thus production
rate can be greatly increased and production bottle necks created by extended drying time
can be brought down to minimum and with the result factory floor space can be put to the
fullest possible use, minimum labor can be employed in view of the high cost of labor and
maximum thermal efficiency can be achieved and hence over all profitability of an industry
can be increased.
SINGHASINI
Tray Dryer consists of rigid angle iron frame covered with heavily insulated glass wool on
all sides to prevent heat losses from the dryer and mild steel sheet covering , provided
with fresh air inlet & adjustable air outlet. The Dryer is finished internally with
SS316 / SS304 or Aluminium sheet or heat resistant Aluminium paint to minimize heat losses
. Heating is done with electrical heaters / steam heaters or indirect fired hot air
generators to achieve required temperature . Cross flow air circulation is maintained in
the dryer in such a way that hot air passes over the trays and through it on the sides
where it is reheated and recirculated to continue the cycle. A part of air is bled off to
reduce moisture content. SINGHASINI tray Dryers are available in 48 , 96 , 192 trays with Aluminium
trays and M.S. trolleys . Explosion safety door is available for special application dryer
. Dryer is provided with Pre-wired control panel consisting of Digital Temperature
Controllers , Contactors , Over Current Relays , Fuses , Indicating Lamps , Push Buttons
etc etc.
