Automatic Iodized Salt Making Machine Salt Production Line

Advanced automatic iodized salt refining processing plant machine

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.
 
Production process flow
Sea Lake Salt Production Line is a set of equipment that our factory has meticulously developed for crude raw sea salt and lake salt.
Various capacity is available for buyer's different requirement (3-30t/h or customized).
 
Three washing is as follows:
First Screw washing
Stand-up stirring washing
Countercurrent washing
 
Three crushing is as follows:
First crushing
Wet crushing
Dry crushing
The combination of first crushing, wet crushing and dry crushing has greatly improved the salt quality. The above operation is adjustable according to the crude salt and user's requirements on finished salt quality.
 
Advantages:
Finished has high purity, shiny appearance, free liquidity and stable iodine content.
Low loss, the loss of NaCl is under 8%.
Low energy consumption and investment.
Equipment is easy to operate and maintain.

Main equipment-2 stage 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.
