Filter Cloth Applications by Slurry
Cloth is selected by the material you are separating, not by a catalogue number. Each slurry that we can actually quote gets its own engineering page.

Two duties are published with full engineering detail. Both run on rubber-belt horizontal vacuum belt filters, and they are not interchangeable.
Phosphogypsum Filtration
By-product gypsum from wet-process phosphoric acid (WPPA) plants, dewatered on rubber-belt horizontal vacuum belt filters.
FGD Gypsum Dewatering
Scrubber gypsum from wet limestone flue-gas desulphurisation, including the wash duty that wallboard-grade buyers care about.
One slurry, one page — and no generic “gypsum cloth”
A belt that works on one slurry is not automatically the right belt for a chemically different one, even when both are calcium sulphate. Phosphogypsum comes out of an acid plant; FGD gypsum comes out of a scrubber. The origin drives the chemistry the fabric sits in, and it drives how the wash stage has to be run.
So we keep them on separate pages, with separate selection logic and separate confirmation lists. Where a duty is genuinely a variant of another — the wallboard-grade FGD buyer, for instance — it lives as its own section inside the parent page rather than as a page of its own.
Different origin (acid plant vs scrubber) and different chemistry (fluoride vs chloride). At least one established weaver publishes separate belt classes for the two duties instead of a single gypsum belt.

Application pages are published in batches as the engineering detail for each duty is confirmed. We would rather publish nothing than publish a page we cannot stand behind.
If you dewater something that is not listed — a phosphate rock concentrate, a lithium tailing, a metal concentrate on a tower press — send it through the engineering RFQ anyway. You will get an honest answer about whether it is a duty we can quote, including when the answer is no.
