Anping County Boli Hardware Wiremesh Products Factory (established in 1998) presents our high-performance Sintered Wire Mesh Perforated Filter Plate – a precision-engineered solution specifically designed for coal washing and solid-liquid separation processes. With a thickness of 1.5 mm, this filter plate combines the durability of sintered wire mesh with the precise opening geometry of perforated plates, ensuring reliable filtration, easy cleaning, and long service life in demanding industrial environments.
Our sintered mesh filter plates are manufactured using advanced sintering technology that bonds multiple layers of wire mesh together under high temperature and pressure, creating a rigid, porous structure with uniform pore distribution. The perforated design further enhances flow capacity while maintaining mechanical strength. This product is widely used in coal washing plants, mineral processing, chemical filtration, and water treatment applications where consistent filtration performance and resistance to abrasion are critical.
Key Features & Technical Specifications
- Material: Made from high-quality stainless steel (304, 316L, or custom alloys) – excellent corrosion resistance and high-temperature stability.
- Thickness: 1.5 mm (±0.05 mm tolerance) – optimized balance between strength and filtration efficiency.
- Filtration Precision: Customizable from 5 microns to 500 microns, depending on your specific separation requirements.
- Perforated Pattern: Round holes, square holes, or slotted holes – available in various open area ratios (up to 60%).
- Size: Custom dimensions to fit your filter press, centrifuge, or other equipment – typical sizes range from 200×200 mm to 2000×1000 mm.
- Structure: Sintered multi-layer wire mesh bonded to a perforated metal plate – no delamination, no media migration.
- Surface Finish: Smooth, burr-free edges – optional pickling and passivation for enhanced anti-rust properties.

Advantages for Coal Washing Plants
- Enhanced Dewatering Efficiency: The sintered mesh structure provides uniform capillary action, improving water removal from coal slurry.
- Long Service Life: Resistant to abrasion from coal particles and repeated backwashing cycles – reduces replacement frequency.
- Easy Cleaning: Smooth surface and rigid construction allow simple mechanical or chemical cleaning without damaging the filter media.
- Customizable to Equipment: Can be cut, drilled, and shaped to fit any filter press, vacuum belt filter, or centrifuge.
- Low Maintenance: The sintered bond prevents mesh shifting or tearing, even under high pressure differentials.
For coal washing plants, the 1.5 mm thickness offers an ideal compromise: thick enough to withstand the mechanical stress of pneumatic or hydraulic systems, yet thin enough to allow efficient filtration and minimize dead zones. Our plates are produced with precise CNC punching and laser cutting, ensuring consistent hole diameter and placement. Each plate undergoes strict quality control to guarantee flatness and dimensional accuracy.

Frequently Asked Questions
-
Q: What materials are available for the sintered wire mesh filter plate?
A: We commonly use stainless steel 304 and 316L. Other alloys like Hastelloy or Monel are available upon request for special chemical resistance. -
Q: Can you provide custom sizes for my filter press?
A: Yes, we can produce any size within 2000×1000 mm. Please provide your exact dimensions, hole pattern, and thickness requirements. -
Q: What is the maximum temperature the plate can withstand?
A: For standard 304 stainless steel, the continuous operating temperature is up to 450°C. For higher temperatures, we recommend 310S or Inconel materials. -
Q: How is the filter plate cleaned?
A: Backwashing with water or air is typical. For stubborn deposits, chemical cleaning with mild acids or alkaline solutions is possible. Avoid using abrasive tools that may damage the sintered surface. -
Q: Is the plate suitable for both coal washing and other industrial filtration?
A: Absolutely. It works well in mineral processing, chemical, pharmaceutical, food and beverage, and wastewater treatment applications. -
Q: What is the lead time for a custom order?
A: Typically 15–25 working days after confirmation of drawings and payment. Urgent orders can be expedited. -
Q: Do you offer samples for testing?
A: Yes, we provide small samples (e.g., 200×200 mm) for evaluation. The sample cost is reasonable and can be deducted from future bulk orders. -
Q: How do you ensure the filtration precision is consistent?
A: Every batch is tested with a pore size analyzer and bubble point test. Our QC records are available upon request.
