Can the feed build a stable cake?
Observe pickup, uniformity and the effect of immersion or formation time.

Why testCake formation Dewatering Release
A Mineral Name Is Not a Filtration Result
Two samples with the same commercial ore name can respond differently because grinding, clay, mineralogy, oxidation, reagents and solids concentration change cake structure and permeability.
How does moisture respond?
Measure moisture against vacuum, drying time, cake thickness and media.
Will the cake discharge cleanly?
Check blowback or scraper behavior and whether the medium retains or smears solids.

Build a Repeatable Evidence Package
Record conditions and methods so results can support sizing and later be compared with commissioning data.
Plan sampling
Select normal and difficult feed conditions; document where and when the sample was taken.
Characterize
Record solids, density, PSD, mineralogy, pH, temperature and relevant reagents.
Screen media
Choose candidate cloth or ceramic media based on retention, chemistry and release.
Run cycles
Measure cake formation, drying, moisture, filtrate and discharge across controlled conditions.
Report basis
Summarize flux, recommended media, limitations and the conditions required for scale-up.

Practical answers
Frequently Asked Questions
Use these answers to prepare a useful discussion with BOYUN. Final equipment selection still depends on project data.
Why is representative slurry data required?
Mineral names do not define filterability. Particle-size distribution, mineralogy, clay, reagent chemistry, feed solids and temperature can change cake formation, permeability and release. Use the filterability test process when performance is commercially important.
What information should be sent for a preliminary review?
Provide duty, mineral, dry throughput, feed solids, particle size or P80, target moisture, operating hours, elevation and available utilities through the disc filter quote page.
Does BOYUN guarantee cake moisture from a mineral name?
No. A responsible target must be tied to representative feed data, test conditions and an agreed equipment and operating basis.
Define the Next Engineering Step
Share the slurry, dry throughput, feed solids, particle size and target cake moisture. BOYUN will identify missing data and recommend testing, sizing or a suitable filter configuration.
