Control solids in filtrate
Select a structure that retains the required solids without creating unnecessary resistance.
Media selection for cake and filtrate control
Disc Filter Cloth Bags for Mining Dewatering
Select disc filter cloth bags by slurry size, permeability, cake release and chemical conditions, with fitting support for mineral dewatering applications.

Choose Cloth by Duty, Not Color or Appearance
BOYUN reviews cloth construction together with particle retention, air and liquid permeability, cake release, chemistry, cleaning and the installed sector.
Support stable cycle performance
Balance cake pickup, drying and flow across normal and difficult feed conditions.
Discharge cake without media damage
Evaluate surface behavior, blowback and mechanical contact under the real cycle.
Compatibility comes before price
Provide a used or unused reference cloth when possible, plus its construction record, sector drawing and slurry data. Material names alone do not define weave, finish, permeability or dimensional fit.
Specification basis
Cloth Selection Data
A useful quotation identifies the interface and operating duty instead of relying on a photograph or equipment name.

PermeabilitySpecified test method, pressure basis and acceptable range.
Retention dutyPSD, valuable-fines loss limit and filtrate clarity target.
Chemical conditionpH, reagents, temperature, oxidation and cleaning exposure.

Screen, Fit and Verify the Media
Record the installed condition so a replacement can be checked before dispatch.
Characterize slurry
Capture PSD, chemistry, solids and variation.
Define acceptance
Set filtrate, cake, release and service-life goals.
Screen cloth
Compare candidate constructions with a consistent method.
Verify fit
Check bag geometry, seams and fastening on the sector.
Trend in service

Service-life controlWashing Process Handling
Extend Cloth Life Without Hiding Process Problems
Cleaning and replacement intervals should respond to measured condition and the cause of blinding or damage.
Control wash coverage
Inspect nozzles, pressure, water quality and alignment without exceeding the cloth’s mechanical limits.
Track feed changes
Relate early blinding or poor release to fines, solids, reagents and cycle changes.
Install without damage
Protect seams and surfaces from sharp sector edges, excessive tension and tools.
Safety before inspection or maintenance
Stop the equipment and isolate all hazardous energy that can cause rotation, vacuum, pressure, stored mechanical movement, electrical energization or chemical exposure. Follow the site lockout and permit procedure; inspection and maintenance must be performed only by authorized personnel.

Connect Parts to the Installed Filter
Use the equipment and service pages to confirm model, duty and replacement planning.
Practical answers
Frequently Asked Questions
These answers support project preparation; the final recommendation depends on the actual duty.
Why is representative slurry data required?
Mineral names do not define filterability. Particle-size distribution, mineralogy, clay, reagents, solids and temperature can change cake formation, permeability and release. Use filterability testing when results matter commercially.
What should be sent for a preliminary review?
Provide dry-solids throughput, feed solids, particle-size data, target cake moisture, operating schedule, elevation and available utilities through the quote request.
Can BOYUN promise cake moisture from the mineral name alone?
No. A defensible target must be tied to representative feed data, test conditions, equipment scope and an agreed operating basis.
Define the Next Engineering Step
Share the feed, throughput, operating target and site constraints. BOYUN will identify missing information and recommend testing, sizing or the appropriate equipment scope.
