Salt Machinery ,Salt Processing, Washing and Refining and Whole Salt Production System from China Supplier
Process of the plant
Raw salt is sent to a feed hopper at appropriate capacity and then transferred to a conveyor band.
A magnet is used to remove trash metals from this conveyor.
Raw salt is washed in a special washing system.
Crude salt is ground in a wet grinding system with a saturated brine.
Salt slurry is sent to a tank and pumped to a washing tank with one of centrifugal, high-pressure pump, centrifugal pump, axial flow pumps or gear pump.
Slurry is removed from slurry in washing tank.
Saltwater overflowing from washing tank is recycled.
Salt slurry is sent to hydrocyclone to thicken it.
Salt is removed from water in large scale by centrifugation. Iodine dosing is made.
In the fluidized bed dryer, salt is completely dried.
Drying milling is done to thin clumping salts.
Salts are passed through a screening machine to be classified.
Then the tablet salt will be carried out, fine grade salt is packed in different packages.
We has designed a unique washing system that is based in salt and brine countercurrent system in a custom designed screw. The washing process allows to identify soluble and insoluble impurities in raw salt using an advanced countercurrent brine system.
The washing and purification system is based in a mechanical principle of pure brine washing to increase purity of the salt crystals.
After the Washing process the salt goes into a centrifuge system with the latest centrifuge technology in order to further wash and purify the crystals while reducing humidity of the product in the process.
Salt centrifuges allow for precise liquid-solid separation process. A continuous separation process engineered to combine high availability with minimum maintenance.
we have developed our own Fluid Bed dryer technology, designed to provide continuous drying solutions for all types of salts (sea salt, rock salt, vacuum and/or lake salts). Manufactured in the best materials for resistance and avoiding corrosion.
Our drying system allows to dry and cool Salt using a combination of airspeed and mechanical motions to treat each particle efficiently and with minimum dust formation. By shacking the product up and down we achieve a uniform drying result with shorter time and lower temperature.
We has also engineered a crushing process to control the size of the Salt grain. With our horizontal roller crushers, the product goes in a vertical flow and the machine allows to control de crystal size. Our crushing and grinding machines are produced with high quality stainless steel and allow the operator to adjust the size of the crystal that will go out of the process.
we do offer a machinery range to add additives in Salt. It can be either Iodine, Fluor or anti-caking. The solution is a linear system that pulverizes the additive in the production a uniform way in order to obtain the Iodized Salt without any problem. Our process guarantees a perfect distribution of additives in the Salt crystals and meets the highest food and grocery standards required for food-grade distribution.
We also support through our equipment supply the global and national iodine programs, working with key public, private, scientific and civic stakeholders. We focus on universal salt iodization as the most cost-effective and sustainable solution for prevention of iodine deficiency disorders.
Main equipment- Pusher centrifuge Introduction
HP Series automatic salt production plant is a kind of perforated basket centrifuge, both continuous and effective. The mixture to be separated is fed through the feeding pipe and the distributor continuously and evenly into the first stage basket. Most of the mother-liquor in the feed, acted on by centrifugal force, departs through the sieves into the liquor-collecting casing where it will be discharged out of the machine. The first stage basket rotates and reciprocate, pushing the formed product cake into the second stage basket .The cake can have sufficient retardation in the centrifuge with being acted on by more centrifugal force, and therefore, the desired humidity of the cake can be guaranteed. Afterwards, the cake is continuously discharged out of the basket. In case of high purity for the solid product, the effective washing can be carried out in the centrifuge. If necessary, the washing agent and the mother-liquor can be discharged separately.
