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 our 18° Filter Sector for Vacuum Disc Filter, specifically engineered for mining dewatering applications. Our sectors are designed to maximize filtration efficiency, reduce downtime, and deliver consistent performance in the most demanding environments. With an annual export value of US$5–10 million, we serve global markets including North America, South America, Europe, Africa, and Oceania, ensuring reliable supply and competitive pricing.
The 18° filter sector is a critical component in vacuum disc filters, commonly used in mineral processing plants for dewatering of concentrates and tailings. Our sectors are manufactured with precision using high-quality polypropylene (PP) or optionally stainless steel, and feature a robust design that resists wear, corrosion, and deformation. The 18° angle is optimized for efficient cake discharge and washing, improving overall filtration cycle performance.
Below you will find a detailed overview of the product's specifications, technical benefits, and why our factory is the preferred partner for mining operations worldwide.
Key Features & Technical Specifications
- Precision 18° Angle: Ensures optimal cake discharge, reduces filter cloth blinding, and improves washing efficiency.
- High-Performance Material Options: Standard PP (polypropylene) for cost-effectiveness and chemical resistance; optional stainless steel for high-temperature or abrasive applications.
- Reinforced Structure: Available with fiberglass or steel insert for extra rigidity, preventing warping under heavy vacuum pressure.
- Customizable Filtration Fineness: From 10 to 200 microns, tailored to your specific slurry characteristics.
- Compatible with Major OEM Brands: Designed to fit standard vacuum disc filter frames (e.g., Outotec, FLSmidth, Metso, etc.).
- Easy Installation: Pre-drilled mounting holes and simple clamp system for quick replacement without special tools.
- Low Maintenance: Smooth surface and anti-clog design reduce cleaning frequency and extend service life.

Advantages for Mining Dewatering
In the mining industry, efficient dewatering is crucial for reducing moisture content in final products, minimizing transportation costs, and improving subsequent processing. Our 18° filter sector delivers several key benefits:
- Increased Throughput: The optimized 18° angle allows faster cake formation and better washing, leading to shorter cycle times and higher processing capacity.
- Reduced Moisture Content: Superior vacuum distribution and drainage channels result in lower residual moisture in the filter cake, often achieving
- Extended Service Life: High-quality materials and reinforced construction resist cracking, warping, and chemical attack, even in acidic or alkaline slurries common in mining.
- Enhanced Cake Release: The tapered design and smooth surface facilitate easy discharge, reducing downtime for cleaning and minimizing cloth wear.
- Cost-Effective Solution: Our direct manufacturing approach eliminates middlemen, offering competitive pricing without compromising quality. Bulk orders receive additional discounts.

Frequently Asked Questions (FAQ)
-
What is the angle of this filter sector, and why is it important?
The angle is 18°, which is a standard for many vacuum disc filters. This angle optimizes cake discharge and washing efficiency, reducing moisture and improving filtration cycle time. -
Can I get a custom size or material?
Yes, we offer customization in dimensions, material (PP or stainless steel), reinforcement, and filter cloth types. Please provide your drawings or specifications. -
How long does the sector last under normal mining conditions?
Lifespan depends on slurry abrasiveness, temperature, and frequency of cleaning. Typically, our PP sectors last 1–3 years, while stainless steel versions can last 3–5 years or more. Proper maintenance extends life. -
Is this sector compatible with my existing vacuum disc filter?
Our sectors are designed to fit most major brands (Outotec, FLSmidth, Metso, etc.). We can adapt mounting holes and dimensions to match your equipment. Provide your model or measurements for confirmation. -
Do you offer samples for testing?
Yes, we provide free samples (shipping cost borne by the buyer). We recommend testing a few sectors in your filter to verify performance before bulk order. -
What is the minimum order quantity (MOQ)?
For standard sizes, MOQ is 10 pieces. For custom sizes, MOQ may be 50 pieces. Contact us for details. -
How do you pack the sectors for export?
We pack them in sturdy plywood cases or pallets with foam protection to prevent damage during transit. Custom packaging (e.g., with your logo) is available upon request. -
Can you provide technical support after purchase?
Absolutely. Our team offers installation guidance, troubleshooting, and advice on optimizing filtration parameters. We are committed to your long-term success.
