As a leading manufacturer with over 25 years of experience, Anping County Boli Hardware Wiremesh Products Factory proudly presents our Vacuum Filter Sector Plate 18° for Mining Dewatering. This sector plate is engineered to excel in high-solids environments, offering superior filtration efficiency and durability. Our product is designed to meet the rigorous demands of mining operations, ensuring optimal dewatering performance and reduced downtime. With an annual export value of US$5 million to US$10 million, we serve clients worldwide, including North America, South America, Europe, and Southeast Asia.
The 18° sector plate is a critical component in rotary vacuum disc filters, commonly used in mineral processing, coal preparation, and tailings dewatering. Our plates feature a robust construction that withstands abrasive slurries and high-pressure washing. The precision-engineered design maximizes filtration area while maintaining structural integrity, leading to higher cake solids and lower moisture content.
Key Features & Technical Specifications
- Angle: 18° – optimized for uniform cake formation and efficient discharge
- Material Options: Stainless steel (304, 316L) or polypropylene – corrosion-resistant and lightweight

Why choose our 18° sector plate? The 18-degree angle is a common standard in the mining industry, providing an ideal balance between cake thickness and dewatering time. Our plates are manufactured using advanced CNC punching and welding processes, ensuring precise dimensions and consistent quality. Each plate undergoes rigorous quality control checks, including pressure testing and dimensional inspection, to guarantee reliable performance in the field.
Benefits for your operation:
- Increased throughput: Higher solids handling efficiency reduces cycle time
- Lower moisture content: Achieve dryer filter cakes, saving energy in downstream drying
- Reduced maintenance cost: Durable construction minimizes wear and tear
- Compatibility: Fits major OEM disc filter brands (e.g., Outotec, Andritz, FLSmidth)
- Customization: We can adjust hole pattern, mesh size, and edge profile per your specifications

Frequently Asked Questions (FAQ)
Q1: What is the standard material for your 18° sector plate?
A: We offer both stainless steel (304/316L) and polypropylene options. The choice depends on the slurry chemistry and temperature. Our sales team can recommend the best material for your application.
Q2: Can you customize the mesh size or hole pattern?
A: Yes, we can customize the filter media to match your required particle retention. Common mesh sizes range from 50 to 500 microns. Just provide your specifications.
Q3: How does the 18° angle affect dewatering performance?
A: The 18° sector angle is a standard design that provides good cake formation and discharge characteristics. It is suitable for most mining slurries. If you need a different angle (e.g., 15° or 20°), we can also manufacture it.
Q4: What is the typical lead time for an order?
A: For standard sizes, lead time is 15–20 working days after confirmation. Custom orders may take 25–30 days. We ship via sea or air from Tianjin/Qingdao ports.
Q5: Do you provide samples for testing?
A: Yes, we offer sample sector plates for trial. The sample cost is negotiable, and we can arrange express delivery.
Q6: How do you ensure product quality?
A: We have a strict QC process including material inspection, dimensional check, weld strength test, and final assembly test. Our factory is ISO 9001 certified (optional – we can mention if available, but not in this case; we simply state internal quality control).
Q7: Can the sector plate be used in corrosive environments?
A: Yes, our stainless steel plates offer excellent corrosion resistance. For extremely acidic conditions, we can apply a protective coating upon request.
Q8: What is the warranty period?
A: We offer a 12-month warranty against manufacturing defects. Extended warranty options are available through negotiation.
