Strainer Basket

Q1: How does a rotary drum screen cylinder&wedge wire basket strainer work?

A rotary drum screen cylinder separates solids from liquids by rotating a cylindrical wedge wire screen. The rotation allows continuous filtration, where solid particles are captured on the screen surface while liquids flow through.

Q2: What are the main advantages of wedge wire basket strainers?

High mechanical strength

Precise filtration with slot sizes as small as 20 microns

Easy cleaning and backwashing

Corrosion resistance (stainless steel or special alloys)

Long service life compared to perforated or mesh strainers

Q3: How is a wedge wire basket strainer different from a perforated basket strainer?

Unlike perforated strainers that rely on drilled holes, wedge wire basket strainers use V-shaped wire profiles. This design reduces clogging, improves flow efficiency, and provides more accurate filtration.

Q4: What materials are used to manufacture rotary drum screen cylinders?

Most rotary drum screens are made from stainless steel grades such as SS304 or SS316L, which provide excellent corrosion resistance and durability in harsh environments.

Q5: Can wedge wire basket strainers be customized?

Yes. They can be manufactured in different diameters, lengths, slot sizes, and end connections to meet specific flow rates, pressures, and industry requirements.

Q6: What slot size should I choose for my application?

Slot size depends on the type of liquid and the particle size you want to filter. For fine filtration, smaller slot openings (20–200 microns) are recommended. For coarse separation, larger slot sizes (0.5–2 mm) may be suitable.

Q7: How do you maintain a rotary drum screen cylinder?

Regular maintenance includes periodic backwashing, surface cleaning, and inspection for wear. Because wedge wire is durable, maintenance is minimal compared to conventional screens.

Q8: What is the typical lifespan of a wedge wire basket strainer screen?

With proper use and maintenance, stainless steel wedge wire basket strainers can last 5–10 years or longer, depending on operating conditions.

Q9: Are wedge wire basket strainers suitable for high-pressure systems?

Yes, wedge wire baskets are designed with high mechanical strength and can handle both high flow and high pressure, making them ideal for demanding industrial applications.

Q10: Can rotary drum screens handle abrasive materials?

Yes, wedge wire construction provides excellent resistance to abrasion, making rotary drum screen cylinders suitable for applications involving sand, slurry, or mining operations.

Q11: What are common applications of rotary drum screen cylinders?

They are used for wastewater pretreatment, sludge dewatering, fruit and vegetable washing, fish processing, pulp recovery in paper mills, and cooling water intake screening.

Q12: How do wedge wire screens prevent clogging?

The V-shaped wire profile allows solids to sit on the surface while liquids flow freely, reducing the risk of clogging and ensuring consistent performance.

Q13: Where can I purchase wedge wire basket strainer screens and rotary drum screen cylinders?

YUBO offers a range of wedge wire basket strainers, including both standard and custom-designed models.
