As a trusted manufacturer since 1998, Anping County Boli Hardware Wiremesh Products Factory specializes in precision-engineered filtration components. Our 18° Sector Plate for Vacuum Filter is designed to deliver reliable performance in demanding dewatering applications. With a robust 6mm thickness and precisely machined 1.0mm slots, this sector plate is perfectly sized for 2.5m diameter vacuum disc filters, ensuring optimal filtration efficiency and long service life. Backed by our annual export value of US$5-10 million and a global customer base, we bring decades of expertise to every product.
The sector plate is a critical component in rotary vacuum disc filter systems, commonly used in mineral processing, coal washing, and chemical slurry dewatering. Our plate is manufactured using high-quality materials and advanced stamping/welding techniques to maintain dimensional accuracy and structural integrity under heavy loads. The 18° arc design matches standard filter disc segments, allowing easy replacement and seamless integration with existing equipment.
Key Features & Technical Specifications
- Precision Slots: 1.0mm slot width ensures efficient liquid drainage while retaining fine solids. Slot edges are smooth and burr-free to prevent clogging.
- Durable Construction: 6mm thick plate provides exceptional rigidity, resisting deformation under vacuum pressure and mechanical stress.
- Exact Fit: Designed for 2.5m diameter vacuum disc filters, with 18° sector angle for standard 20-sector configuration (360°/20 = 18°).
- Material Options: Available in carbon steel (with anti-corrosion coating) or stainless steel (304/316L) for enhanced chemical resistance.
- Customizable Surface Treatment: Galvanized, painted, or rubber-lined options available upon request to meet specific corrosion or wear requirements.
- Consistent Quality: Each plate undergoes rigorous inspection including slot width measurement, flatness check, and dimensional verification.

Our sector plates are engineered to optimize the filtration cycle: during operation, the plate rotates through the slurry tank, where vacuum draws liquid through the slots while solids form a cake on the surface. The 1.0mm slot size strikes an ideal balance between high filtration rate and minimal solid loss. The 6mm thickness ensures the plate remains flat even under high vacuum levels, preventing premature wear and maintaining consistent cake discharge.
Compared to thinner or poorly manufactured plates, our product offers longer service life and reduced downtime. The precise slot geometry also minimizes blinding, keeping filtration efficiency high over extended periods. We understand that every operation has unique requirements, so we offer customization in terms of slot width, material grade, and coating to match specific slurry characteristics.

Frequently Asked Questions
-
Q: What materials are available for the sector plate?
A: We offer carbon steel (with optional anti-corrosion coatings) and stainless steel grades 304 and 316L. The choice depends on the slurry's pH, abrasiveness, and temperature. We can recommend the best option based on your process conditions. -
Q: Can you customize the slot width?
A: Yes, slot width can be customized from 0.5mm to 2.0mm to suit different particle sizes. However, the 1.0mm slot is a standard option that works well for many applications. Please provide your specific requirements, and we will adjust the design accordingly. -
Q: How do I know if this plate fits my 2.5m filter?
A: The 18° sector plate is designed for standard 20-sector disc filters. If your filter has a different number of sectors, we can manufacture plates with alternate angles (e.g., 15°, 20°, etc.). Please confirm your filter's sector count and diameter before ordering. -
Q: What is the typical lead time for an order?
A: For standard sizes and materials, lead time is 15-20 working days. Custom orders may require 25-30 working days. We can expedite for urgent projects upon request. -
Q: Do you provide samples for testing?
A: Yes, we can provide sample plates for your evaluation. The sample cost is typically refundable upon placing a bulk order. Please contact our sales team to arrange. -
Q: How do you ensure the slot quality?
A: Each plate is inspected using slot gauges and optical measurement tools. We also perform flatness checks and dimensional verification against CAD drawings. Our quality control system ensures consistent slot width and edge smoothness. -
Q: What surface treatment is recommended for corrosive environments?
A: For highly corrosive slurries (e.g., acidic or saline), we recommend stainless steel 316L or carbon steel with a rubber lining. For mild environments, hot-dip galvanizing provides excellent protection at a lower cost. -
Q: Can I get a technical drawing or 3D model?
A: Certainly. We can provide 2D drawings and 3D models (STEP/IGES format) upon request to help you verify compatibility with your filter assembly.
