Product Description

Technical Characteristics

In the salt washing process, crushing is a crucial step that determines the fineness, uniformity and purity of the final washed salt. Unlike the traditional single-stage crushing, the two-stage crushing system (primary + secondary) is specifically designed for the washed raw salt - ensuring precise particle size control, reducing impurities and perfectly matching the subsequent washing and screening processes. It solves the pain points of uneven particle size, excessive fine powder and poor compatibility with washing equipment, thereby enhancing production efficiency and product quality.

Crushing process flow (fully compatible with the entire salt washing line): The two-stage crushing process can be seamlessly integrated into the entire salt washing process, with the following flow.

Product Description

Significant advantages: The two-stage crushing after washing avoids the problem of crushed salt being re-contaminated by impurities, ensuring the purity of the final product, while precisely controlling the particle size.

Primary Crusher: Coarse Crushing After Washing (0.2 - 0.6 mm)
Core features of the primary crusher
Precise particle size control: Fixed output particle size of 0.2 - 0.6 mm, uniform particle size (85% or more of the particles within the target range), no over-crushing or large particle residue.
Corrosion-resistant and moisture-proof: Made of anti-rust and corrosion-resistant alloy materials (high-chromium alloy rollers), suitable for washed salt with a certain moisture content (≤8% moisture), no clogging or rusting.
Low fine powder loss: Uses a gentle extrusion crushing mode, reducing fine powder (≤0.1 mm) to less than 10%, maximizing product yield and reducing waste.
Secondary Crusher: Fine Crushing (0.1 - 0.5 mm)
Easy to match: Compact structure, easy to connect with subsequent conveying equipment and stirring washing machines, no need to modify the existing production line layout.
Adjustable particle size: Stepless adjustment of output particle size (0.1 - 0.5 mm), customizable according to customer requirements for finished products (table salt, industrial salt, etc.).
High purity guarantee: Closed crushing design, no dust, no external impurity contamination, ensuring clean salt particles after washing.
Energy-saving and low noise: Low-speed operation, 25% more energy-efficient than traditional fine crushers; noise ≤ 70 decibels, meeting environmental protection standards.
Easy to maintain: Modular design, quick replacement of worn parts (rollers, scrapers), simple daily maintenance, reducing downtime.

Frequently Asked Questions

Why is a two-stage crushing system preferred over single-stage crushing?
A two-stage system prevents re-contamination from impurities, ensures tight particle size distribution (85%+ uniformity), and substantially reduces excessive fine powder generation compared to single-stage units.
Can the crushers handle wet or damp salt?
Yes. The rollers are manufactured with high-chromium alloy materials designed to resist corrosion and rust, specifically suited to handle wet salt containing up to 8% moisture without clogging.
How does the equipment control the formation of fine salt dust?
By utilizing gentle extrusion crushing instead of high-impact grinding, the machine reduces fines smaller than 0.1 mm to below 10%, maximizing production yield and purity.
Is the final product size adjustable in the secondary crusher?
Yes, the secondary crusher features stepless particle size adjustment from 0.1 mm to 0.5 mm, allowing flexible application for both table salt and industrial salt production.
How easy is it to perform routine maintenance on the rollers?
The system utilizes a modular design that facilitates swift replacement of wear parts, such as scrapers and roller covers, minimizing production downtime.
