Anping County Boli Hardware Wiremesh Products Factory, established in 1998 with an annual export value of US$5–10 million, proudly presents our 316L Stainless Steel Perforated Filter Plate featuring a precision 3mm hole size, specifically engineered for efficient coal dewatering. As a trusted manufacturer serving global markets including North America, Europe, Southeast Asia, and Africa, we combine decades of wire mesh expertise with advanced perforation technology to deliver a product that withstands harsh environments and delivers consistent filtration performance. Our filter plates are the backbone of dewatering systems in coal preparation plants, ensuring reduced moisture content and enhanced material handling efficiency.
Product Features & Technical Specifications
- Superior Corrosion Resistance: Made from 316L stainless steel, this perforated plate offers excellent resistance to chlorides, acids, and alkaline slurries common in coal dewatering processes, extending service life significantly compared to 304 or mild steel.
- Optimized 3mm Hole Size: The 3mm round holes are precision-punched to provide an ideal balance between water drainage and solid retention, preventing clogging while maximizing dewatering capacity.
- High Mechanical Strength: The perforated plate retains structural integrity under heavy loads and vibration, thanks to the robust 316L material and optional thickness customization (e.g., 2mm, 3mm, 4mm).
- Consistent Open Area: Our advanced CNC punching machines ensure uniform hole spacing and edge smoothness, achieving a high open area ratio (typically 30–60% depending on pitch) for superior flow rates.
- Customizable Dimensions: Available in any sheet size up to 1500x3000mm, with custom shapes, cutouts, and edge finishes to fit your existing dewatering equipment (e.g., vibrating screens, sieve bends, filter presses).
- Low Maintenance: Non-porous surface and smooth hole edges minimize material buildup, making cleaning easy and reducing downtime.

Key Benefits for Coal Dewatering Applications
- Reduced Moisture Content: The precise 3mm holes allow rapid water drainage while retaining fine coal particles, helping you achieve lower product moisture and higher thermal efficiency.
- Extended Service Life: 316L stainless steel provides exceptional resistance to corrosion and abrasion from coal slurry, reducing replacement frequency and total cost of ownership.
- Improved Equipment Compatibility: Our plates can be manufactured with curved shapes, slotted holes, or custom bolt patterns to exactly match your vibrating screen or sieve bend.
- Enhanced Operational Efficiency: High open area and smooth hole edges minimize blinding and pegging, ensuring consistent dewatering performance over long production runs.

Frequently Asked Questions (FAQ)
-
Q: What is the difference between 316L and 304 stainless steel for coal dewatering?
A: 316L offers superior corrosion resistance to chlorides and acidic conditions often present in coal slurries, making it more durable and longer-lasting than 304. It is recommended for high-moisture or chemically aggressive environments. -
Q: Can the hole size be customized for other applications?
A: Yes, we offer customizable hole diameters from 0.5mm to 25mm. For coal dewatering, 3mm is a standard size, but we can adjust based on your specific particle size and flow requirements. -
Q: What is the typical lead time for a custom order?
A: Lead time depends on quantity and complexity. Generally, standard sizes ship within 10–15 working days. Custom shapes or large orders may require 20–30 working days. We can expedite for urgent orders upon request. -
Q: Do you provide samples for testing?
A: Yes, we offer free samples (around 200x200mm) for most standard specifications. You only need to cover the shipping cost. Contact us for more details. -
Q: How do I choose the right plate thickness and pitch?
A: Thickness should be selected based on mechanical load and vibration intensity. For most vibrating screens, 3mm or 4mm thickness is sufficient. Pitch determines open area — a smaller pitch (e.g., 4.5mm) gives higher open area but may reduce strength. Our technical team can advise based on your equipment parameters. -
Q: Can you produce curved or bent perforated plates?
A: Yes, we can produce curved plates (e.g., sieve bends, cylindrical screens) with the same perforation pattern. Please provide a drawing or dimensions of the required curvature. -
Q: What packaging do you use for export?
A: Plates are packed in wooden crates or steel pallets with protective layers to prevent scratches and deformation during sea freight. Each bundle is clearly labeled with specifications. -
Q: Do you accept small minimum order quantities (MOQ)?
A: Our MOQ is typically 10 pieces for standard sizes, but we can negotiate for sample orders or trial batches. Contact us for your specific needs.
