Frequently Asked Questions
Q1: What is the standard thickness of the dewatering plate?
A: While we offer thicknesses from 2mm to 10mm, the most common choices for coal washing are 3mm, 5mm, and 8mm. The optimal thickness depends on the load and operating conditions.
Q2: Can the hole size be customized to other diameters?
A: Yes, we can produce holes from 0.5mm to 20mm in diameter. The 2mm is a popular size for fine coal dewatering, but we can adjust according to your product specifications.
Q3: How does the plate resist clogging from sticky coal fines?
A: Our holes are punched with a clean, burr-free edge. Combined with the staggered pattern, this minimizes particle adhesion. Additionally, the 304 stainless steel surface is smooth and non-stick, further reducing clogging.
Q4: Do you offer plates with reinforced edges or mounting holes?
A: Absolutely. We can add welding strips, flanged edges, countersunk holes, or any other customization to match your screen frame or filter press.
Q5: What is the typical lead time for an order?
A: For standard sizes and quantities, lead time is 7–15 working days. Custom orders may require additional time depending on complexity. We can expedite urgent orders upon request.
Q6: Are samples available for testing?
A: Yes, we provide free samples (customer pays shipping). We recommend testing the plate in your actual dewatering process to verify performance.
Q7: How do you ensure the flatness of large plates?
A: We use precision leveling machines after punching and strict QC inspection with a flatness tolerance of ≤2mm per meter, ensuring the plate fits perfectly in your equipment.
Q8: What is the minimum order quantity (MOQ)?
A: Our MOQ is typically 10 pieces for standard sizes, but we can discuss smaller quantities for trial orders. Contact our sales team for details.
