Support surface
Support the cloth while allowing filtrate to reach internal drainage paths.
Drainage support and media interface
Vacuum Disc Filter Sectors and Sector Plates
Source replacement vacuum disc filter sectors and sector plates for mining dewatering. Review dimensions, materials, cloth attachment and model compatibility.

The Sector Connects Cake Formation to the Vacuum Path
A sector supports the filter medium, collects filtrate and seals into the disc assembly. Geometry or drainage differences can affect both fit and filtration.
Neck and sealing connection
Match the center-shaft or manifold connection, sealing method and assembly spacing.
Cloth attachment
Confirm bag shape, fastening method, edge protection and replacement access.
Compatibility comes before price
Compatibility requires a controlled drawing or verified sample. Record the disc diameter, number of sectors, sector angle, neck interface, mounting details, material and cloth attachment method.
Specification basis
Sector Identification Checklist
A useful quotation identifies the interface and operating duty instead of relying on a photograph or equipment name.
Filter modelSeries, nominal area, disc diameter and serial/project reference.
Disc layoutNumber of discs and sectors per disc; installed position if variants exist.
GeometryLength, angle, thickness, neck and mounting dimensions.
ConnectionPort, seal, fastener and center-shaft interface.
MaterialExisting construction and chemical/abrasive exposure.
Media fitCloth bag dimensions, fastening and edge details.
Replacement workflow1 2 3 4 5
Control Fit Before Site Installation
Record the installed condition so a replacement can be checked before dispatch.
Identify assembly
Record filter, disc and sector arrangement.
Capture dimensions
Use a drawing, scan or verified physical sample.
Review material
Connect corrosion and abrasion to the actual duty.
Approve drawing
Confirm interfaces and revision before production.
Trial fit
Check sealing, runout, clearance and cloth fit safely.
Service-life controlSurface Connection Alignment
Maintain the Sector as Part of the Disc
Repeated cloth damage, leakage or uneven cake may indicate an underlying sector or assembly issue.
Inspect support condition
Look for distortion, sharp edges, blocked drainage and damage that can mark the cloth.
Check seals and fastening
Investigate air ingress, movement and uneven assembly before replacing media again.
Verify disc clearance
Confirm runout, scraper relationship and neighboring sector spacing after work.
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.
