316L Sintered Stainless Steel Mesh Filter Cartridge For Spodumene Acid Leaching & Evaporation Crystallization

Product Details

This 316L sintered stainless steel mesh filter cartridge is specially designed for high-temperature and highly corrosive conditions such as ore acid leaching and evaporation crystallization. It is made of multi-layer 316L stainless steel wire mesh through laminating, pressing and vacuum high-temperature sintering. With rigid structure, it provides excellent heat and corrosion resistance, stable for spodumene acid leaching solution filtration and high-temperature crystallization processes, supporting continuous operation above 200°C.

Key Features

Superior Corrosion Resistance: 316L with molybdenum enhances resistance to chloride ions and sulfuric acid (≤80%), stable in acidic ore leaching solutions.

Extreme High Temperature Resistance: Withstands up to 600°C without gaskets; stable at 200°C+ for long-term operation.

High Strength & Pressure Resistance: Working pressure ≥3.0 MPa forward, ≥1.5 MPa reverse; no deformation under high pressure.

5-Layer Gradient Sintered Structure: Pre-filtration + fine filtration + support for high efficiency and long service life.

Anti-fouling & Easy Regeneration: Supports backwash, ultrasonic cleaning, pickling and passivation; flux recovery ≥90%; service life up to 3–5 years.

Low Pressure Drop: Porosity 35%–50%, runs efficiently at differential pressure ≤0.3 MPa to save energy.

Sanitary Optional: Electropolished surface (Ra≤0.8 μm) for food and pharmaceutical grade applications.
