De-icing salt are indispensable in winter road maintenance. An advanced deicing agent production line not only serves as the foundation for large-scale manufacturing but also plays a crucial role in enhancing product performance and reducing environmental impact.
Recently, Lane launched a de-icing salt granule production line centered on twin-roll extrusion granulation technology. This upgrade to core processes improves adaptability to diverse raw materials, enabling the production of high-quality de-icing salt granules.
A complete de-icing salt granule production line constitutes a highly automated system engineering solution designed to transform powdered raw materials into high-strength, dust-free, uniform granules. Its standard process flow includes: raw material pretreatment → precise mixing → double roller extrusion granulation → grading and screening → finished product packaging.
The entire system seamlessly integrates six major modules—automatic batching, mixing, granulation, screening, packaging, and electrical control—enabling continuous operation from feedstock input to finished product. This ensures stable production efficiency and consistent product quality.
The double roller granulator is the ‘heart’ of the de-icing salt granule production line. It employs a unique dry extrusion molding principle, eliminating the need for water or binders and requiring no subsequent drying.
Working Principle: Uniformly mixed dry powder feedstock is forcibly fed by a screw conveyor between two counter-rotating rollers. Under immense hydraulic pressure, the material undergoes plastic deformation and is extruded through die holes on the roller surfaces, forming dense flakes or flattened pellets. These flakes are then crushed, rounded, and screened to produce uniformly sized final granules.
Process Advantages:
LANE’s de-icing salt granule production lines offer flexible adaptation to diverse raw materials. By adjusting ingredient ratios, they produce products tailored to varying market demands.
Economical & Efficient Option – Chloride Salts
Environmentally Friendly Premium Type – Organic Salts
Market Trend – Composite Formulations
The current market mainstream is composite de-icing agents. By scientifically blending the aforementioned chloride salts and adding functional additives like corrosion inhibitors and anti-caking agents, the following are achieved:
De-icing Salt Granule Production Line and Raw Material Synergy: The double roller extrusion process imposes strict requirements on raw material moisture content (typically <5%) and particle size. Consequently, production lines are often equipped with drying, crushing, and high-efficiency mixing equipment at the front end to ensure stable and efficient formulation processing.
The granular de-icing salt produced by this De-icing Salt Granule Production Line offers significant advantages over traditional powdered products:
Modern de-icing salt granule production lines, especially those centered on twin-roll extrusion granulation technology, are no longer mere processing equipment. They represent integrated solutions that blend mechanical engineering, materials science, and environmental sustainability.
By transforming inexpensive, dust-prone powdered raw materials into efficient, eco-friendly, high-value granular products, it not only generates significant economic returns for investors but also provides robust technical support for advancing winter road safety maintenance toward greater efficiency, environmental sustainability, and intelligent operation.
