Select a filter press from the slurry and the result your plant needs
A useful filter press proposal starts with the operating problem, not a catalogue model number. Compare the application routes below, then use test data and site constraints to confirm the press structure.
See the sizing data checklist
01
Mining tailings and mineral concentrates
Abrasive slurry, high solids loading, repeat cycles and cake handling are reviewed together.
02
Coal washing and mineral slurry
Variable feed, cloth blinding, cake release and continuous operating demand guide the selection.
03
Wastewater and industrial sludge
Throughput, conditioning, filtrate quality, floor space and operator access are checked early.
04
Chemical, ceramic and food process filtration
Material compatibility, cleanability, sanitary duty and explosion-proof requirements determine the build.

Machine details that should be checked before confirming a filter press
A filter press proposal should not rely only on model names. The feed end, hydraulic closing system, plate shifting structure, drip tray, plate pack and operation space all affect long-term maintenance.
Technical parameters
Typical specification range for chamber and membrane filter presses
The following values are used as a practical starting point. Final data should be confirmed according to slurry test, cake thickness, filtration area, working pressure, local power and the required automation level.
Press typeRecessed chamber filter press, membrane filter press, automatic hydraulic filter press
Plate size630, 800, 1000, 1250, 1500, 2000 mm; larger sizes reviewed by project
Filtration areaApproximately 20-1000 m² depending on plate size, chamber depth and plate quantity
Filter plate materialReinforced PP chamber plate, PP membrane plate or rubber membrane plate by application
Feed pressureCommonly 0.6-1.0 MPa; higher pressure configuration checked by slurry and press structure
Membrane squeezeAir or water squeezing system selected when lower cake moisture is required
Plate shiftingManual, semi-automatic or automatic plate pulling according to press size and cycle frequency
Control systemLocal control cabinet, PLC control, hydraulic closing, pressure holding and optional remote signals
Optional equipmentFeed pump, drip tray, cloth washing, cake conveyor, platform, guard rail, slurry tank and pipeline valves
ApplicationsMining tailings, coal washing, wastewater sludge, chemical slurry, ceramic slurry and industrial process filtration
Selection logic
When to choose chamber type, and when to choose membrane type
A chamber press is often enough when the material forms cake easily and the moisture target is moderate. A membrane press is more suitable when the buyer needs extra squeezing after feeding, lower residual moisture, better cake discharge or a shorter operating cycle.
Choose chamber press when
The slurry is stable, cake moisture target is not extreme, project budget is sensitive and maintenance should stay simple.
Choose membrane press when
Cake dryness, washing effect, cycle time or difficult cake release has a direct effect on operating cost.
Ask for test data when
The slurry is new, particle size changes, solids content is unstable or chemical compatibility is uncertain.
Confirm layout before order
Discharge height, pump position, maintenance aisle, platform, foundation and local power supply should be reviewed early.

Information needed before sizing a filter press
A reliable proposal needs more than a capacity number. Send slurry information, target result and site limits so the press, filter plate, cloth, pump and control level can be matched together.
Material name, solids content, particle size, pH and temperature
Feed volume per hour or per day and expected operating hours
Target cake moisture, filtrate clarity and whether cake washing is needed
Available floor space, discharge height, power supply and automation preference
Existing press model, plate size or site photos if this is a replacement project
Filter press selection FAQ
Direct answers before requesting a technical proposal
These questions cover the information that most often changes equipment size, operating cycle and the final dewatering result.
What information is needed to size an industrial filter press?
Useful sizing data includes slurry name, solids concentration, particle size, pH, temperature, feed volume, operating hours, target cake moisture, filtrate requirement, site space, power supply and the preferred automation level.
When should a membrane filter press be selected instead of a chamber filter press?
A membrane press is normally considered when additional squeezing can reduce cake moisture, shorten the cycle, improve cake release or support cake washing. A chamber press is often sufficient for stable slurry that forms cake easily and has a moderate moisture target.
What determines the final cake moisture?
Cake moisture depends on slurry solids, particle-size distribution, compressibility, feed pressure, filtration time, cake thickness, filter cloth, membrane squeeze conditions and washing requirements. It should not be guaranteed from the press model alone.
Can the system include pumps, conveyors, washing and controls?
Yes. The press can be reviewed together with the plate pack, filter cloth, feed pump, hydraulic station, PLC controls, drip tray, cloth washing, cake conveyor, platform, tanks, valves and piping.
