As a leading manufacturer with over 26 years of expertise in wire mesh products, Anping County Boli Hardware Wiremesh Products Factory introduces our Stainless Steel 304 Wedge Wire Conical Centrifuge Filter Basket specifically designed for coal vibrating screens. This industrial-grade filter basket combines superior dewatering performance with exceptional durability, ensuring efficient separation of fine coal particles and maximized throughput in demanding mining operations. Our conical design optimizes centrifugal force distribution, reducing wear and extending service life.
Crafted from high-quality Stainless Steel 304, this wedge wire basket offers excellent corrosion resistance against coal slurry and acidic mine water. The precision-welded V-shaped wires create a self-cleaning slot profile that minimizes clogging and maintains consistent flow rates. Each basket is manufactured to tight tolerances, with slot openings ranging from 0.1mm to 10mm to meet various classification and dewatering requirements. The conical structure ensures smooth material discharge and prevents accumulation at the bottom.
Key Features & Technical Specifications
- Material: Premium Stainless Steel 304 (optional 316L for higher corrosion resistance)
- Wire Profile: Wedge wire (V-shape) – continuous slot opening for efficient filtration
- Slot Accuracy: ±0.05mm tolerance ensures uniform particle separation
- Conical Angle: Customizable – typically 5°–15° to optimize centrifuge performance
- Reinforced Rings: Heavy-duty support rings at top and bottom for structural integrity
- Welding Process: Resistance welding with full penetration – no cold joints
- Surface Finish: Pickled and passivated for smooth surface and easy cleaning
- Custom Dimensions: Diameter, height, and slot size can be tailored to your specific screen machine

| Max Operating Temperature | Up to 400°C (752°F) | Suitable for hot coal slurry |
Advantages & Customer Benefits
- Higher Dewatering Efficiency: The wedge wire profile delivers maximum open area, allowing rapid water drainage while retaining fine coal particles. This reduces moisture content in the final product, improving coal quality and reducing transportation costs.
- Extended Service Life: Stainless Steel 304 resists corrosion from sulfur, chlorides, and acidic mine water. The conical shape distributes centrifugal load evenly, reducing stress concentration on wires and support rings. Typical lifespan is 2–3 times longer than traditional perforated screen baskets.
- Self-Cleaning Action: The V-shaped slot design prevents particles from wedging into the openings. During operation, the centrifugal force pushes particles outward, keeping slots clear and maintaining consistent throughput.
- Low Maintenance: Smooth surface finish and robust weld joints minimize the need for frequent repairs. Our baskets are designed for easy installation and replacement, reducing downtime.
- Customizable to Your Equipment: We work closely with clients to match exact dimensions, slot sizes, and mounting configurations for various centrifuge models (e.g., TEMA, Siebtechnik, CMI, and others). No need to modify your existing screen deck.
- Consistent Performance: Precision manufacturing ensures each basket meets strict quality standards. Every unit undergoes dimensional inspection and slot uniformity test before shipment.
Our basket is widely used in coal preparation plants for vibrating screen dewatering, centrifuge filtration, and fine coal recovery. It also performs excellently in other industries such as sand & gravel, mineral processing, and chemical filtration where reliable separation is critical.

Frequently Asked Questions (FAQ)
-
Q1: What is the difference between a conical and a cylindrical centrifuge basket?
A: A conical basket (tapered) allows the material to slide down automatically due to gravity and centrifugal force, enabling continuous discharge. Cylindrical baskets often require additional scraper mechanisms. For coal vibrating screens, conical design is more efficient for dewatering and has lower maintenance. -
Q2: Can you provide baskets with slot openings less than 0.1mm?
A: Yes, we can manufacture slots as small as 0.05mm for special applications. However, please note that very fine slots may require higher pressure and could be more prone to clogging if the feed contains near-size particles. We recommend a slot size of 0.2mm–0.5mm for typical coal dewatering. -
Q3: What is the typical lead time for a custom basket?
A: Standard lead time is 15–25 working days after order confirmation, depending on quantity and complexity. For urgent orders, we can expedite production to 10–15 days. -
Q4: Do you offer a warranty on your filter baskets?
A: Yes, we provide a 12-month warranty against manufacturing defects. Issues caused by improper installation, abnormal operating conditions, or wear and tear are not covered. We also offer after-sales technical support to help you maximize basket life. -
Q5: How do I determine the correct conical angle for my centrifuge?
A: The optimal angle depends on the material properties (particle size, moisture content, abrasiveness) and the centrifuge speed. Typically, 10° is a common starting point for coal. Our engineers can recommend the best angle based on your specific data. We can also provide samples for testing. -
Q6: Can your baskets be used in vibrating screens other than centrifuges?
A: Yes, our wedge wire baskets are versatile and can be adapted for use in vibrating screen decks, dewatering screens, and some static sieves. However, the conical shape is specifically optimized for centrifugal force. For flat vibrating screens, we also offer wedge wire panels in flat or curved designs. -
Q7: What packaging do you use for export?
A: Each basket is individually wrapped with anti-corrosion paper and then packed in a reinforced wooden crate to prevent damage during transit. We can also customize packaging according to your requirements (e.g., fumigation-free wood for certain markets). -
Q8: How do you ensure the slot accuracy during production?
A: We use advanced CNC wedge wire winding machines and laser measurement systems. Each basket is inspected using a feeler gauge and optical comparator. A sample inspection report can be provided with the shipment upon request.
