Start with the Feed, Product and Water Balance
Lead and zinc circuits may produce separate concentrates with different filtration behavior. Do not transfer one stream’s test result or cloth selection to the other without evidence. The engineering review connects feed preparation, filtration, filtrate handling and cake discharge to one measurable duty.
Reagent effects on cake formation
Define the measurable outcome and the downstream reason it matters.
Separate or combined concentrate duties
Confirm how the circuit will be started, controlled, cleaned and maintained.
Selection boundary
Lead and zinc circuits may produce separate concentrates with different filtration behavior. Do not transfer one stream’s test result or cloth selection to the other without evidence.

Build the Dewatering Duty Before Selecting the Machine
A defensible selection follows the material through the circuit and keeps every assumption visible.
Collect feed data
Sample normal and difficult campaigns; record solids, PSD, mineralogy, pH, temperature and reagents.
Define acceptance
Set moisture, solids-retention and filtrate criteria before testing.
Run testwork
Measure cake formation, drying response, release and filtrate quality with candidate media.
Calculate area
Use tested dry-solids flux, operating hours, availability and design margin.
Confirm system
Review vacuum, filtrate, blowback, feed, discharge, access, controls and utilities.

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.
