Anping County Boli Hardware Wiremesh Products Factory, established in 1998, is a professional manufacturer specializing in woven wire mesh and filter cloth products. Our Dewatering Filter Cloth Bags for Disc Vacuum Filters are engineered to deliver superior performance in mineral processing applications. With over two decades of manufacturing experience and annual export value exceeding US$5 million, we provide reliable filtration solutions that enhance dewatering efficiency, reduce downtime, and optimize operational costs. These bags are tailored to fit various disc vacuum filter models, offering excellent filtration precision and long service life.
Our dewatering filter cloth bags are crafted from high-quality synthetic materials such as polypropylene, polyester, and nylon, ensuring excellent chemical resistance and mechanical strength. The unique weaving structure allows for effective cake formation and rapid moisture removal, which is critical in mineral processing operations like coal washing, iron ore dewatering, and copper concentrate filtration. The bags are designed to withstand high-pressure environments and repeated use, making them a cost-effective choice for continuous mining and mineral processing plants.
Key Features & Benefits
- High Filtration Efficiency: Precision-woven fabric ensures consistent particle retention, achieving clear filtrate and lower moisture content in the cake.
- Excellent Durability: Resistant to abrasion, chemicals, and high temperatures, extending service life and reducing replacement frequency.
- Customizable Dimensions: Available in various sizes, shapes, and stitching styles to match specific disc filter models (e.g., 12-disc, 24-disc configurations).
- Optimized Cake Release: Smooth surface finish minimizes cake adhesion, improving filter cycle times and reducing cleaning efforts.
- Low Maintenance: Easy to install and replace, with minimal downtime required for changeovers.
- Wide Application Range: Suitable for dewatering of coal, iron ore, copper, gold, and other minerals, as well as industrial sludge and waste water treatment.

Our dewatering filter cloth bags are manufactured using advanced weaving and finishing technologies, including heat setting and calendering, to ensure dimensional stability and uniform pore distribution. The bags are available with different edge treatments (folded, welded, or stitched) to match your filter sector design. We also offer custom options such as reinforced seams, grommets, and anti-static treatments.
Frequently Asked Questions
1. What materials are available for these filter bags?
We offer polypropylene, polyester, and nylon. Polypropylene is suitable for acidic conditions, polyester for high-temperature applications, and nylon for abrasive environments. Please consult us for material selection based on your slurry chemistry.
2. How do I determine the correct size for my disc vacuum filter?
We need the dimensions of your filter sector (length, width, and thickness) as well as the number of sectors per disc. Our team can provide a template or recommend standard sizes. Custom sizes are always available.
3. What is the typical lifespan of these bags?
Lifespan depends on operating conditions such as slurry temperature, pH, abrasiveness, and cleaning frequency. Under normal mineral processing conditions, our bags can last 3-6 months or longer. We can provide samples for on-site testing.
4. Do you offer samples before bulk order?
Yes, we offer free samples for evaluation (shipping cost may apply). Samples are typically available in 200mm x 200mm pieces or small bags. Please contact us with your requirements.
5. How do I clean and maintain these filter cloth bags?
We recommend periodic washing with high-pressure water or diluted acid/alkali solutions depending on the clogging material. Avoid using sharp tools to prevent damage. Proper maintenance can extend bag life significantly.
6. What is the minimum order quantity (MOQ)?
Our MOQ is 50 pieces per size, but we can be flexible for trial orders. For large projects, we can negotiate competitive pricing.
7. Can these bags be used in other industries besides mineral processing?
Yes, they are also suitable for chemical, food, pharmaceutical, and wastewater treatment industries where solid-liquid separation is required. Please confirm the compatibility with your process.
8. What is the lead time for production?
Standard lead time is 15-20 working days after order confirmation and sample approval. Urgent orders can be arranged with a surcharge.
