Salt Refining Process Description

Salt Refining Process Description

The Raw Salt will be loaded to the hopper through which it will enter the Special Washing System. The flow rate will be measured here and controlled to set it as per the pre-decided rate based on the purity of raw salt. In the Screw Washery, the major portion of the impurities will be removed. The washed salt will enter the wet Mill Section (Grinding/ Hammer Mill). The brine is added here to give slurry output from the mill. The output is tanked into a slurry tank where further brine is added. The slurry is then pumped to the Elutriation tank for washing. The washed slurry is then transferred to Thickener and decanted brine is transferred to the clarifier by means of Elutriation & wash tank. From here the clear brine is transferred to the brine tank and remaining to the settling pond. Here at settling pond, the settled mud is drained and the upper layer of clear brine is pumped to the Screw Washery. The Salt after removal of water in Thickener is fed to the Centrifuge. In Thickener, the slurry concentration achieved is 50%.

The salt will then be centrifuged to liquid form and it will be conveyed through the blender cum screw conveyor and belt to fluidized bed dryer.

Then dry and cooled salt Will travel to Vibro screen through bucket elevator.

After screening, the undersize will be conveyed to a blender cum screw conveyor. Here the Free Flow Agent will be mixed at a specified and predetermined flow rate.

The blender cum conveyor will mix the content well and convey the same to a silo. The finished goods from the silo bottom will be conveyed and distributed by a screw conveyor to Packing Machines. Then the pouches of 1.0 Kg. will be sealed. Another conveyor will carry the refined salt to the bagging and stitching machine where it will be packed in 50Kg bags.

The four washing is as follows:

First Screw washing

Second screw washing

Stand-up stirring washing

Countercurrent washing

Three-crushing is as follows:

First crushing

Wet crushing

Dry crushing

The combination of wet crushing, dry crushing and different ways of washing has greatly improved the salt quality. The above

operation is subject to adaptation according to the users’ different requirements due to the use of crude salt of different

quality

The following is the technical procedure of our typical ‘four-washing, three-crushing’ technology.

Advantage of our salt machine:

The high quality refined salt product has high purity, shiny appearance, good free liquidity and stable iodine content.

Low loss, the loss of NaCl is under 10%.

Low energy consumption and investment.

Equipment has long service life, easy to operate and maintain.

Parts of Equipment-Belt Conveyer Features

Belt conveyer has the advantages of large transportation throughout, simple structure, easy maintaince and part standardization. It is widely used in salt, chemical, food grain industries for transporting of loose materials and packed products. According to the requirements of transportation technology, single conveyer can be operated or more belt conveyers can work together. It can be composed with other transportation equipments in from of horizontal or inclined transportation systems for the operation requirements from different layouts. Transportation speed can be designed as fixation or continuous variable transmission. Belt conveyers can be used at the temperature range of -20℃ +40℃ and transporte material temperature below 50℃.
