Salt Crushers
Specialized mill for potassium/sodium salt crystals with anti-corrosion design.
Product Overview
Our Salt Crusher is a specialized milling machine designed for efficient processing of potassium and sodium salt crystals in harsh industrial environments. Engineered with advanced anti-corrosion technology, it ensures reliable performance in high-salinity, moisture-rich, or chemically aggressive conditions. Ideal for salt mining, chemical processing, and food-grade salt production, this crusher combines precision grinding with durability to meet the demands of modern industrial operations.Key Applications
- Mining & Mineral Processing: Crushing raw potassium/sodium salt crystals into uniform granules.
- Chemical Industry: Preparing salt feedstocks for electrolysis, fertilizer production, or industrial chemical synthesis.
- Food & Pharmaceutical: Grinding food-grade or medical-grade salts to meet strict hygiene and purity standards.
Design & Performance Features
1. Anti-Corrosion Engineering
- Material Construction:
- Main Body: Stainless steel (SS316L/904L) or carbon steel with polymer coatings (PTFE/EPOXY) to resist salt crystallization and chloride-induced corrosion.
- Grinding Components: Tungsten carbide or ceramic-coated blades/rollers for enhanced wear resistance.
- Sealed Design: IP65-rated enclosures protect internal mechanisms from salt dust and moisture ingress.
2. Precision Grinding
- Adjustable Particle Size: Output granularity ranges from 0.1–10 mm, controlled via modular screen configurations.
- Throughput Capacity: 5–50 tons/hour (model-dependent), suitable for batch or continuous processing.
- Low Heat Generation: Water-cooled bearings and optimized rotor design minimize thermal degradation of salt crystals.
3. Energy Efficiency
- Motor System: IE3/IE4 high-efficiency motors with variable frequency drives (VFDs) to reduce energy consumption by 15–25%.
- Dust Suppression: Integrated cyclonic filters or baghouse systems capture 99% of airborne particulates, ensuring compliance with workplace safety standards.
4. Operational Safety
- Overload Protection: Automatic shutdown sensors for torque overloads or foreign object intrusion.
- Easy Maintenance: Quick-release panels and tool-free access to blades/screens for cleaning and part replacement.
