Why Filter Plates Crack & Fracture
Symptoms · Root Causes · Proven SolutionsFilter plates crack at corners, edges and feed holes under long-term high pressure, causing heavy slurry spray and equipment-safety risks.
What Is Happening?
Filter plates crack at corners, edges and feed holes under long-term high pressure, causing heavy slurry spray and equipment-safety risks.
Common Symptoms
- Visible cracks or splits on plate surfaces and corners
- Heavy slurry leakage from cracks during filtration
- Hydraulic clamping pressure cannot remain stable
- Uneven stress damages adjacent plates
4 Root Causes
Foreign Material
Debris or wrinkled cloth is trapped during clamping.
Material Degradation
Heat or chemical attack weakens plate toughness.
Uneven Slurry Filling
One-sided chamber filling creates unbalanced stress.
3 Recommended Actions
Control Feed Pressure
Keep pressure within the plate rating and increase it gradually.
Inspect Before Clamping
Remove foreign objects and lay cloth flat before startup.
Replace Aged Plates
Use corrosion-resistant plate material matched to the slurry.
