Product Specification

Sea Table Salt Powder Making Machine and Salt Refinery Equipment Supplier in China

High quality salt production line

Customized Salt processing line machinery

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.

Detailed Process Description

Salt washing plant, salt crush and wash plant, salt impurity extraction plant etc are defined as a mechanical refining system. The main idea is to break the big salt granules to expose as many as possible the impurities and wash out the impurities from the surface of the granules.

The updated break system is roller pulverizes with roller surface specially processed so that it works mainly cutting the granules to get the less salt powder. And we combine the latest technology of screw washing + stirring washing+ elutriating counter-current washing which can most effectively wash out the impurities and have less loss of NaCl. After the salt is crushed and washed, it goes to drying system to make it dry to required moisture content Iodine and/or free-flow agent is added as per requirement by customers. Sieving system is applied to classify different size of granules as per different application (cooking salt, table salt, industrial salt etc) after sieving the salt is packed either into big bags of 50kgs (or any other size required by clients) and small bags of 250-1000g (or any other size required by customers) the finish salt is dry, white, glossy, free flow.

According to raw salt quality, we have combination of 3crushing+4washing, 3 crushing+3washing, 2crushing+2washing, and dry crushing.

Main equipment- 2 stage pusher centrifuge features

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.
