Table Iodized Industrial Salt Processing Plant with ISO9001
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. On its way to dryer, it will be iodized.
The washed salt with Iodine Solution will get fluidized in Dryer and Iodine mixing will uniform. 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.
Feature of the plant
For less salt loss, washing process is carried out in conjunction with countercurrent washing technology.
Iodine or other additives are added according to customer needs.
After drying, screening process is applied to classify granules in different
Advantage of our equipment line
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.
Vibrating Fluidized Bed Dryer Features
HP series vibration fluidized bed dryer is driven by the vibration force caused by vibration motor. The material in a given direction under the action of the force of leaping forward, at the same time a bed type cloth uniform wind hot air in a fluidized state of material, material particles in contact with the hot air fully, intense heat and mass transfer process, high thermal efficiency, cavity in the state of the negative pressure, moist air is being exhausted from induced draft fan, dry material is being exhausted from port layout, so as to achieve the ideal effect. This machine is widely used in salt industry of powdery and granular materials such as operation of drying, cooling and humidifying.
