Salt Purification Process: Enhancing Quality & Removing Impurities

This page explains the salt washing process in plain language. No hype—just what it is, why it matters, and how the core steps work from storage to final handling.

Salt washing is a key step in salt processing. The goal is straightforward: remove common impurities—such as dirt and other unwanted particles—so the finished salt meets the quality needs for food or industrial use. The process relies on clean water contact and controlled handling to keep the salt uniform and safe.

• Storing: Salt is kept in dedicated silos or bays. Stable storage before and after washing helps prevent moisture pickup and cross-contamination.
• Conveying: Conveyors or screw feeders move the salt steadily into the washer, keeping flow consistent and minimizing losses.
• Washing: Inside the washer, salt meets clean water. Agitation and controlled flow help lift away impurities so they can be separated from the product.
• Dewatering & After-Treatment: Washed salt is separated from water, then conditioned—typically dried and screened—before safe storage or packing.

Washer: A dedicated washer brings salt and water into contact. The motion inside the machine helps separate unwanted material from the salt grains.

Conveyors & Feeders: These keep material moving at a steady rate, which supports consistent cleaning and gentle handling.

Dewatering & Handling: After washing, equipment removes excess water and prepares the salt for drying, screening, and storage.
