As a leading manufacturer with over 25 years of experience in the wire mesh and filtration industry, Anping County Boli Hardware Wiremesh Products Factory proudly presents the 18° Rubber Screen Filter Sector for disc vacuum filters. Engineered with a precise 70 Shore A hardness and exceptional wear resistance, this sector is designed to maximize filtration efficiency while minimizing downtime. Our advanced manufacturing process ensures consistent quality and long service life, making it a reliable choice for demanding solid-liquid separation applications.
Each sector is crafted from premium rubber compounds that offer outstanding resistance to abrasion, chemicals, and temperature variations. The 18° angle is optimized for smooth cake discharge and uniform filter cloth support, ensuring optimal vacuum performance. Whether you are processing minerals, chemicals, or industrial slurries, our rubber screen filter sector delivers superior dewatering results and reduced maintenance costs.
Key Features & Technical Specifications
- Material: High-quality rubber blend (NR/SBR) – excellent wear and tear resistance
- Hardness: 70 Shore A – balanced flexibility and rigidity for efficient cake release
- Angle: 18° – precise geometry for standard disc vacuum filter sectors
- Wear Resistance: Enhanced surface treatment prolongs service life by up to 30% compared to standard rubber sectors
- Temperature Range: -20°C to +80°C (other ranges available upon request)
- Compatibility: Fits most disc vacuum filter models (e.g., 2.5m, 3.0m, 3.6m disc diameters)
- Customization: Available in different thicknesses, colors, and hardness levels (60–80 Shore A)
| Parameter | Value |
|---|---|
| Sector Angle | 18° |
| Hardness (Shore A) | 70 |
| Tensile Strength (MPa) | ≥ 12 |
| Elongation at Break (%) | ≥ 350 |
| Abrasion Loss (mm³) | ≤ 150 (DIN 53516) |
| Operating Temperature | -20°C to +80°C |
Our rubber screen filter sectors are manufactured using compression molding technology, ensuring uniform density and precise dimensions. The 70 Shore A hardness provides an optimal balance – soft enough to seal effectively against the filter disc, yet firm enough to resist deformation under vacuum pressure. The wear-resistant surface reduces the frequency of replacements, directly lowering your operational costs.
Advantages for Your Application
- Improved Dewatering Efficiency: The 18° angle promotes uniform cake formation and easy discharge, increasing throughput by up to 15%.
- Extended Service Life: High wear resistance means fewer replacements – typical lifespan exceeds 12 months under normal conditions.
- Reduced Maintenance: Seamless rubber surface minimizes clogging and cleaning time.
- Cost-Effective: Competitive pricing without compromising quality – save up to 20% compared to OEM alternatives.
- Flexible Customization: We can adjust hardness, thickness, and even color to match your specific process requirements.
Our rubber sectors are widely used in mining (copper, iron, gold, coal), chemical processing, food & beverage, and wastewater treatment industries. They are compatible with major disc filter brands such as Eimco, Dorr-Oliver, and Andritz, as well as many custom designs.
