Precision screens for batch centrifugal filtration and continuous centrifugals
A working centrifugal screen lines the sugar centrifugal basket and does the primary separation. It holds crystals while draining molasses, which improves purity, shortens cycle time, and reduces sugar loss. Fine Perforators supplies fit-ready screens in stainless steel, copper, and brass made to your requirements. Screens are suitable for sugar mills and are also used in chemical, pharmaceutical, and food processing where clean discharge and repeatability are important. Competitive pricing for bulk orders is available.
At a glance:
A working centrifugal screen is the operational liner inside the sugar centrifugal basket. It is the surface that meets the massecuite, holds the sugar crystals, and lets the molasses drain. In batch centrifugal filtration and continuous machines, the right aperture gives cleaner separation, shorter cycle time, and lower sugar loss.
This screen is different from the backing or supporting screen. The backing screen adds stiffness and support behind the working surface, while the working screen does the actual screening. Both are used together for a stable basket set.
For best results, choose slot width by crystal size, massecuite viscosity, and your target cycle time. Typical working ranges start near 0.04 mm and go up as the duty demands. If you are replacing an existing part, we can match the aperture map from a CAD file or a used sample so the new screen fits and performs like the old one.
We supply fit-ready working centrifugal screens for leading sugar centrifugal OEMs. Share your model or basket size and the required aperture, and we will quote the exact fit.

Slot and hole sizes, center pitch, open area, and layout guide for sugar centrifugal screens
Over the years, we have developed our infrastructure and manufacturing units to meet the diversity in the global demand for working screens. The working screens, we manufacture and export, are available in a range of materials including stainless steel, copper, and brass. We supply ready to fix screens with or without fine-finished lock-lap joints. The readily available for supply working screens with standard specifications are as listed below but we have much more to offer in the line of your specific requirements.

Working screens are supplied in stainless steel, copper, and brass to suit sugar processing and related wet applications. Surfaces are finished for smooth sugar contact, easy cleaning, and reliable discharge. Edges are trimmed and burr-free so panels fit correctly and run without scraping.
Brass Centrifugal Liners
In sugar processing, the working centrifugal screen lines the basket in batch and continuous machines. It holds crystals and drains molasses to deliver cleaner separation, shorter cycle time, and lower sugar loss. Mills tune slot width in the 0.04 mm to 0.12 mm range and set the pitch to hit purity and moisture targets. A fit-ready screen with consistent open area helps keep massecuite handling stable, improves throughput across the campaign, and reduces changeovers and rework in the centrifugal screen basket.
These screens are also used in chemical, pharmaceutical, and food processing for reliable solid - liquid separation with clean discharge. Oil and gas and petrochemical plants specify them for guard screening and steady drainage in centrifugals, while algae and biotech applications use them for biomass harvesting and slurry dewatering. Across these sectors, buyers look for the same results from a working centrifugal screen: accurate apertures, smooth surfaces that clean quickly, and repeatable performance from batch to batch.
Fine Perforators manufactures and exports high quality working centrifugal screens, along with backing and supporting screens. As an ISO 9001:2015 certified manufacturer with decades of experience, we produce batch centrifugal working screens to your requirements and ship on schedule. Buyers in India and many other countries choose us for consistent quality, fit ready supply, and complete export documentation.
Reliable export supply with clear paperwork and safe packing
Fine Perforators exports working centrifugal screens to Brazil, Mexico, Dubai, the Philippines, Thailand, Vietnam, Pakistan, Bangladesh, Iran, Jordan, Malaysia, Sri Lanka, and Indonesia. Orders ship on planned schedules with competitive pricing for bulk orders, fit-ready supply, and responsive updates from confirmation to dispatch.

Centrifugal filtration uses high rotational force to separate solids from liquids. In a sugar centrifugal, massecuite feeds into a rotating basket. The working screen holds the crystals while molasses drains through the apertures. In batch machines the cycle is fill, spin, wash, dry, discharge. In continuous machines the feed is steady. Aperture size, open area, and layout control drainage rate, retention, purity, and cycle time.
Yes. We manufacture and supply brass liners matched to your basket ID, width, and thickness. Liners can ship as a set with new working screens for a consistent fit. Brass is preferred in many mills for smooth running, stable wear, and easy maintenance. Share a drawing or sample and we will quote the exact size.
Start with crystal size and massecuite viscosity, then set a target cycle time. Typical working ranges are 0.04 mm to 0.12 mm, with wider slots available when faster drainage is needed. Share your current settings and we will suggest a tested range.
Yes. We supply working centrifugal screens for both batch centrifugal filtration and continuous centrifugals. Provide the model or basket size for an exact fit.
