Why Filter Cloth Wrinkles, Bulges & Misaligns
Symptoms · Root Causes · Proven SolutionsFilter cloth bulges under feed pressure and forms folds that become trapped between sealing surfaces, causing slurry leakage and rapid local abrasion.
What Is Happening?
Filter cloth bulges under feed pressure and forms folds that become trapped between sealing surfaces, causing slurry leakage and rapid local abrasion.
Common Symptoms
- Folds and bulges appear in the center after feeding
- Slurry sprays continuously from plate gaps
- Local abrasion and holes appear at wrinkle positions
- Cloth shifts sideways during plate pulling
4 Root Causes
Pressure Shock
Excessive initial feed pressure impacts the cloth violently.
Wrong Cloth Size
The cut cloth is too large or small for the plate chamber.
Blocked Feed Hole
Uneven chamber filling deforms and shifts the cloth.
3 Recommended Actions
Match Size & Tension
Customize the cloth to the plate chamber and hang it with uniform tension.
Use Step-Up Feeding
Increase feed pressure gradually to avoid sudden impact.
Keep Feed Holes Clear
Clean the central feed hole regularly for uniform chamber filling.
