Product Overview
Nickel Micro Screens for Sugar Continuous Centrifugals
Nickel micro screens are the primary separation component in sugar continuous centrifugal machines. Positioned inside the centrifugal basket, the screen allows liquid molasses to pass through its precisely formed slots while retaining sugar crystals for discharge. The slot width, open area, surface finish, and structural integrity of the screen directly determine how efficiently your centrifugal separates sugar from molasses — and how much sugar you recover from each tonne of cane processed.
Samruddhi Enterprises manufactures electroformed nickel micro screens for A, B, and C massecuite continuous centrifugals. Our screens are produced using 99.99% pure virgin S-grade nickel; no scrap, formed by a fully automated electroforming process, and finished with 12–18 micron hard chrome plating for extended wear resistance.
We supply two product ranges:
- Standard Nickel Micro Screens — our full range of established screen models, covering all standard slot widths, open areas, and machine dimensions used in the Indian and international sugar industry
- Modified Nickel Micro Screens — our proprietary high-performance screen with higher open area, tighter slot tolerances, and greater thickness than standard screens, available for B and C massecuite grades
Key Features and Benefits
Why Our Screens Perform
- 99.99% pure virgin S-grade nickel; no scrap — higher purity produces a more uniform crystal structure, lower internal stress, and better resistance to the corrosive environment inside a sugar centrifugal
- Electroformed slot geometry — slots are grown by the electroforming process, not cut or punched, producing a smooth conical internal profile that promotes self-cleaning and resists blinding
- 12–18 micron hard chrome plating — above the industry standard of 8–12 microns, providing a harder surface and measurably longer service life before slot enlargement affects performance
- Low internal stress — controlled electroforming parameters eliminate the warping and deformation that can occur with poorly manufactured screens at high centrifugal speeds
- Consistent slot tolerances — fully automated production ensures slot width consistency across the screen surface and from batch to batch
- Extended service life — the combination of high-purity nickel and above-standard chrome plating means our screens last longer than standard-specification alternatives under the same operating conditions
- Custom manufacturing available — any slot width, open area, screen dimension, or non-standard specification can be manufactured from your drawing, sample, or specification

Custom Manufacturing
Custom Screen Manufacturing
We manufacture nickel micro screens to any specification that falls outside our standard range.
- Manufacture to drawing — provide a dimensional drawing and we will produce screens to your exact specification, including non-standard diameters, heights, cone angles, and slot configurations
- Manufacture from sample — if you have an existing screen that needs to be replicated, send it to us and we will measure and reproduce it to the same or improved specification
- Non-standard slot widths — we can produce slot widths other than our standard 0.06mm and 0.09mm range. Tell us your required slot width and open area and we will advise on feasibility
- A massecuite screens — available on request. Contact us with your machine model and specification
- Single screens and bulk orders — both accepted. There is no minimum order quantity
- Short lead time on repeat orders — customers who have ordered previously benefit from faster turnaround as their specification is already in our system
To request a custom screen, send us your drawing, sample, or written specification. We will confirm feasibility and provide a quotation within 48 hours.
