Since 1998, Anping County Boli Hardware Wiremesh Products Factory has been a trusted manufacturer of industrial filtration media. Our Polypropylene Multifilament Filter Cloth is specifically engineered for sand washing dewatering applications, offering reliable performance at operating temperatures up to 80°C. This 1.8m x 20m roll provides an efficient, durable solution for separating fine solids from slurry, helping you achieve higher throughput and reduced downtime. Whether you operate a sand washing plant or a mining facility, this filter cloth delivers consistent dewatering results with exceptional chemical resistance.
Our multifilament polypropylene yarns are woven into a stable fabric that resists abrasion, stretching, and clogging. The 80°C temperature tolerance ensures stable filtration even in hot process streams, while the 1.8m width and 20m length offer ample coverage for belt filters, vacuum filters, or pressure filters. Below are the key technical specifications:
| Parameter | Value / Option |
|---|---|
| Material | 100% Polypropylene Multifilament |
| Weave Pattern | Plain or Twill (customizable) |
| Max Operating Temperature | 80°C |
| Roll Dimensions | 1.8 m width × 20 m length |

Key Features & Benefits:
- High Temperature Resistance: Withstands continuous operation at 80°C, ideal for hot sand washing processes.
- Excellent Dewatering Efficiency: Multifilament structure allows rapid water passage while retaining fine sand particles, reducing moisture content in the final product.
- Chemical & Abrasion Resistance: Polypropylene resists acids, alkalis, and organic solvents, extending service life in harsh environments.
- Customizable Specifications: Available in different weave patterns, weights, thicknesses, and pore sizes to match your specific filtration needs.
- Easy Installation & Maintenance: The flexible yet durable fabric can be cut, seamed, or welded for various filter equipment. Easy to clean and reuse.
- Consistent Performance: Uniform yarn tension and precise weaving ensure stable filtration pressure and minimal blinding.
Technical Advantages for Sand Washing: Our filter cloth is designed to handle the demanding conditions of sand washing dewatering. The open weave structure allows water to drain quickly while the tight multifilament yarns prevent sand from passing through. This results in drier sand cake, faster cycle times, and lower energy consumption for your dewatering equipment. The 1.8m width is compatible with common belt filter widths, reducing the need for additional seaming. The 20m roll length provides long continuous runs, minimizing downtime for replacement.
Application Areas: Not limited to sand washing, this filter cloth is also suitable for coal washing, mineral processing, chemical filtration, wastewater treatment, and food processing. Its versatility makes it a cost-effective choice for many industries.
