Key Features & Technical Specifications
- Material: 316L Stainless Steel – excellent resistance to chlorides, acids, and alkaline environments, ideal for wet coal washing.
- Thickness: 3mm – balances strength and weight, offering long service life without excessive load.
- Hole Patterns: Round, square, slot, or custom shapes – optimized for different particle sizes and dewatering efficiency.
- Hole Diameter: Customizable from 0.5mm to 20mm – tailored to your specific mesh size requirements.
- Plate Dimensions: Custom sizes up to 2000mm x 5000mm (or larger upon request) – fits standard vibrating screens, centrifuges, and other dewatering equipment.
- Open Area: Typically 30%–60% depending on hole pattern – maximizes water drainage while retaining solids.
- Surface Finish: As-rolled, pickled, or polished – optional treatments to reduce friction and improve wear resistance.
- Customization: Full customization available – hole shape, diameter, pattern, plate size, edge treatment, and even special coatings (upon request).

Frequently Asked Questions (FAQ)
-
Q: What is the typical lead time for custom perforated dewatering plates?
A: For standard custom sizes (within 1500x3000mm), lead time is approximately 15–20 working days after order confirmation. Larger or complex orders may require 25–30 days. We always aim to meet your project schedule. -
Q: Can you provide material certificates for 316L stainless steel?
A: Yes, we can provide mill test certificates (MTC) for the raw material upon request. This ensures traceability and compliance with international standards. -
Q: What hole pattern is best for dewatering fine coal (e.g., 0.5-1mm particles)?
A: For fine coal, we recommend slot-shaped holes or small round holes (0.5–1mm diameter) with a staggered pattern to maximize open area while retaining particles. Our engineers can help design the optimal pattern. -
Q: How do you ensure the plates are flat and free from burrs?
A: After punching, we perform a deburring process and then flatten the plates using a roller leveling machine. Each plate is inspected for flatness and edge quality before packaging. -
Q: Can you customize the edge treatment, such as bending or adding mounting holes?
A: Yes, we offer custom edge treatments including bending, flanging, drilling, and welding of mounting brackets. Please provide your detailed drawings for a precise quotation. -
Q: What is the minimum order quantity (MOQ) for custom dewatering plates?
A: Our MOQ is typically 10 pieces for standard sizes, but we can accommodate smaller quantities for prototype or trial orders. Contact us for specific requirements. -
Q: Do you offer samples for testing before mass production?
A: Yes, we can provide samples (custom or from stock) for a nominal fee. The sample cost is often refundable upon placing a bulk order. Please inquire. -
Q: How do you pack the plates to prevent damage during shipping?
A: Plates are packed in wooden crates or steel pallets with protective cushioning between layers. For fragile or large plates, we use additional reinforcement to ensure safe arrival.
