Russell Finex Grading & Sizing Separators

Separate your material into defined size ranges

Need defined fractions rather than one screened product stream?

Grading separates feed into specified size ranges. Multi-deck equipment belongs within this category: each mesh makes a cut, so the arrangement is selected around the fractions you want to collect.

Typical application
Separate granules into fines, an on-spec fraction, and oversize.

Also known as: Grading sieves, multi-deck separators, sizing screens, classifiers.

What this equipment can help you do

Control the size specification

Define which sizes belong in each collected fraction.

Separate useful grades

Collect multiple saleable fractions or remove fines and oversize.

Select the arrangement

Match deck count and mesh openings to the required cuts.

How the process works

Define your size cuts

Set the upper and lower limits for each required fraction.

Screen through the decks

Successive mesh openings separate the feed by particle size.

Collect each fraction

Route fines, target grades, and oversize to separate destinations.

Configuration & selection

Equipment to review: Finex Separator™, Finex®22, Finex Ultima™, and Quantum Separator™.
Multi-deck selection: The Finex Separator can produce up to five size fractions with a suitable configuration.
Performance review: Feed size distribution, cut accuracy, capacity, yield, and acceptable misplacement.

Options to discuss

Deck count and mesh cuts
Separate fraction outlets
Deblinding for difficult powders
Screen changes and cleaning access

Share your incoming size distribution, required size cuts, throughput, moisture, and acceptable product yield. Include photos or drawings when available.

Plan your application review

Is multi-deck a different separation job?

Multi-deck describes a screen arrangement used for grading. The buying decision starts with the size fractions you need, then the deck configuration follows.

Can we discuss a product trial?

Ask RTS about testing with your material. Tell us what sample is available and how you will measure success, including capacity, quality, or recovery targets.

What is needed for a final recommendation?

We will review the product conditions, equipment arrangement, utilities, cleaning method, and target result. Performance needs to be assessed against your actual feed and operating conditions.

View the manufacturer reference. Confirm final specifications and options with the quotation.
