Heavy Duty Rubber Filter Belts - Industrial Filtration Solution
Heavy-duty rubber filter belts are designed for high-pressure, abrasive, and corrosive filtration applications, offering exceptional durability and performance in demanding environments. These belts are commonly used in industries such as mining, wastewater treatment, chemical processing, and food production, where robust filtration is required.
Key Features of Heavy-Duty Rubber Filter Belts
1. Durable Rubber Construction
• Made from high-grade natural rubber, synthetic rubber (EPDM, Nitrile, Neoprene), or polyurethane for superior wear resistance.
• Reinforced with fabric or steel cord layers for added strength and tear resistance.
2. Excellent Abrasion & Impact Resistance
• Withstands heavy loads, sharp particles, and high-pressure washing without degrading.
• Ideal for sludge dewatering, mining slurries, and aggregate processing.
3. Chemical & Temperature Resistance
• Resistant to oils, acids, alkalis, and solvents (depending on rubber type).
• Operates in a wide temperature range (typically -30°C to +120°C, with special compounds for higher temps).
4. Customizable Designs
• Available in different thicknesses (5mm to 30mm+) for varying load capacities.
• Surface textures can be smooth, grooved, or cleated for better filtration and drainage.
• Can include fabric or metal reinforcement for extra stability.
5. Long Service Life
• Resistant to cracking, delamination, and microbial growth.
• Suitable for continuous operation in harsh industrial environments.
