Our Process
MANUFACTURING PROCESS
Procured from solar salt field is subjected to wet milling, three stage washing by raw salt saturated brine, centrifuging, blending with potassium lodate and ferricyanide and then to drying. Dried salt is graded. The crystal size between – 850 to + 150 microns are blended with the suitable quantity of a free flowing agent and packed in consumer pack of net weight 1 kgs. The crystal size of-150 microns are directly packed in laminated iidpe bags in 50 kgs. Lot and sold to chemical, food and various processing industries. 85% – 90% of the products are sold in the consumer market as edible salt and the balance to industries as chemical, bulking or souring agent. The brine rejected after washing of salt is sending to settling pond where it is chemically treated for removing the excess load of calcium, magnesium & sulfates and then allowed to settle down for removing the insoluble impurities. The brine thus generated is sent back again to the plant for washing the common salt. The brine over loated with dirt and insoluble shall be disposed off in the salt creeks near to out plant site. The process as above is indigenously developed and well tried. The above is a continuous process and hence suitable holding up capacities at various stages is provided for ensuring a smooth operation.
OUR MAJOR PRODUCTS
WET MILL
Hammer mill is a economical unit designed for general allround
work for time saving operation. Most often, the only
changes necessary are of Screen, hammers and liners.
Feed Material passes through 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 a screen and type of hammers used.
Washing Tank
This is the second stage of washing. This is used to
wash the salt coming from elutriation tank along
with adequate quantity of brine & slurry. The
washing tank will capture the total discharge of the
wet mill.
Tank will be fabricated from S S 304 3mm thick.
BUCKET ELEVATOR

BELT CONVERTER
We have successfully positioned our organization
as one of the distinguished Belt Conveyor
manufacturers and suppliers. Our organization
offers a wide range Belt Conveyor that is heavily
used in diverse applications. These conveyors
ensure efficient and speedy movement of material
from one workstation to another within a short
period of time. The range of belt conveyors
offered by us includes conveyors for light, medium
and heavy loads with various conveying paths like
curve, inclination or any other path.
CYCLONE
Cyclone dust collectors, named after the cyclone weather phenomenon, are large funnel
shaped sheet metal tubes connected to ducts often used in woodshops, machine shops, manufacturing
plants, and powder processing plants. Dust and debris are sucked in at the top. Air containing fine dust
blows out of the other side of the top, while chips and large dust particles fall out of the bottom into a
drum or bin. Dusty exhaust air is either blown outside or filtered again using media filtration.
VIBRO SCREEN
We have specialized the Design/ making of Vibrating Screens for Salt Industries. The detailed study of SaltGranulometry Granulometry has made us understand the behavior of has made us understand the behavior of dry salt when the particle size variation is quite wide. Our experience has helped us in designing the best antiblinding systems to prevent the choking of fine screen by salt-dust. Our screen units are most efficient, hi dust. Our screen units are most efficient, highly sturdy and have minimum maintenance problems. In order to In order to match the requirement, we make our own vibratory motors for our screen units. These motors take full care of Salt loads and offer longer life to the unit. The unit is mirror finished to minimize the corrosion and hence ensure better life of the unit. We offer the screen in single deck, double deck and more decks as per customer needs.
PIN MILL
Pin Mill is specially designed to deal efficiently and
economically with a wide range of materials and can
be easily adjusted to give the fineness required from a
coarse granulation to finely ground powder.
Pin Mill Grinding is gradually done from the
centre to the periphery of the Rotor, allowing heavy
pieces of material to be reduced by stages to the
fineness required. Constructional materials and
operating components are manufactured out of the
15
best applicable raw materials, so as to yield close
particle size for a similar product.
Pin mill yields greater output in relation to the
Electrical Energy consumed, since the material can be
ground is fed automatically in the centre of the Rotor
by the Feed Hooper provided with an automatic
vibrating tray / rotor feeder & gear box for automatic
feed.

SCREW CONVEYOR
A screw conveyor or auger conveyor is a mechanism that uses a rotating helical screw blade, called a
"fighting", usually within a tube, to move liquid or granular materials. They are used in many bulk handling
industries. Screw conveyors in modern industry are often used horizontally or at a slight incline as an
efficient way to move semi-solid materials, including food waste, wood chips, aggregates, cereal grains,
animal feed, boiler ash, meat and bone meal, municipal solid waste, and many others. The first type of
screw conveyor was the archimedian screw, used since ancient times to pump irrigation water.
They usually consist of a trough or tube containing either a spiral blade coiled around a shaft, driven at
one end and held at the other, or a "shaftless spiral", driven at one end and free at the other. The rate of
volume transfer is proportional to the rotation rate of the shaft. In industrial control applications the
device is often used as a variable rate feeder by varying the rotation rate of the shaft to deliver a
measured rate or quantity of material into a process.
Screw conveyors can be operated with the flow of material inclined upward. When space allows,
this is a very economical method of elevating and conveying. As the angle of inclination increases, the
allowable capacity of a given unit rapidly decreases.
VOLUMETRIC FILLER MACHINE
Volumetric Cup Filler, which is used for handling free flowing,
granular and crystalline products. Moreover, these are also used for
handling sugar, granular pesticides, grains, pulses, whole spices and
pharmaceutical powders. The special enclosed drive and Volume
adjustment mechanisms ensure trouble- free operation in corrosive
atmospheres in industries making salt and detergent powder
Dryer
Static Fluidized Bed Dryer is a very critical equipment
Where there is no moving part inside the Drying Chamber.
The Salt is fluidized, each particle meets the hot air,
Discharges moisture, gets dry and at the same time travels
Forward without any mechanical push. It is amazingly
Handled by the balancing of the hot air through drying fan,
Cold air through cooling fan and exhaust air through
Exhaust fan. This balancing act requires very special skill in
Design and Operation. We have proven-technology for
Designing dryers of any capacity. Since we have basic
Design knowledge of such dryers, we can offer the best
Services to our clients in case of difficulties during
Operation. In salt plants we suggest to go for SS 316L as
MOC for such Dryers
