Neither Technology Wins Every Project
A fair comparison uses the same representative feed, dry-solids throughput, cake requirement, filtrate criteria, operating schedule and system boundary. Brochure headline values from different conditions are not comparable.
| Decision factor | Vacuum disc filter | Filter press |
|---|---|---|
| Operating cycle | Continuous rotation through formation, drying and discharge zones. | Batch filling, pressure filtration, opening and cake discharge. |
| Typical strength | High continuous throughput with substantial area in a compact rotating arrangement. | Higher-pressure dewatering can suit lower-permeability feeds and lower moisture targets. |
| Feed sensitivity | Requires a cake that forms and releases reliably under vacuum. | Can handle some finer or less permeable feeds, subject to cycle time and cloth behavior. |
| Cake handling | Steady discharge can simplify continuous conveying. | Intermittent cake discharge requires batch surge and handling design. |
| Consumables | Filter cloth, seals and wear parts; ceramic is a separate disc-filter option. | Filter cloths, plates, hydraulics and associated wear components. |
| Selection evidence | Vacuum filterability test and cycle basis. | Pressure-filtration test and realistic batch-cycle basis. |

Compare Equal Production, Not Isolated Machines
Include upstream and downstream equipment so energy, labor and availability boundaries are consistent.
Fix the outcome
Use the same dry throughput, moisture, filtrate and washing requirements.
Test both routes
Measure each technology under a defensible cycle and media condition.
Build system scope
Include feed, pumps, air, filtrate, discharge, washing and cake handling.
Compare lifecycle
Review CAPEX, energy, consumables, labor, maintenance, availability and risk.

When Each Route Deserves Closer Study
Use screening to decide what to test—not to skip testwork.
Continuous, filterable duty
Strong candidate when the slurry forms a permeable cake and steady discharge supports plant flow.
Pressure and batch flexibility
Strong candidate when pressure is needed for the moisture target or feed permeability is too low for vacuum.
Test the limiting case
The difficult ore campaign or process upset may control the installed technology and area.

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.
