Straight Hole
Countersunk Hole
Taper Hole
Profiled Hole
Straight Hole
Standard cylindrical perforation with uniform diameter throughout the basket thickness. Ideal for general-purpose screening where consistent hole geometry is required.
Countersunk Hole
Tapered entry profile on the accept side that increases open area and reduces fiber clogging. Enhances throughput capacity while maintaining screening efficiency.
Taper Hole
Gradually expanding hole profile from feed to accept side that promotes smooth fiber passage and reduces plugging in high-consistency applications.
Profiled Hole
Engineered hole geometry with optimized entry and exit profiles for maximum contaminant removal and minimal good fiber rejection.
Open Area Calculation
Precise open area formulas for each hole pattern configuration
60° Pattern
Open Area (%) = d² × 90.7 / t²
90° Staggered
Open Area (%) = d² × 78.5 / t × t1
90° Inline
Open Area (%) = d² × 78.5 / t × t1
60° Alternate
Open Area (%) = d² × 90.7 / t²
Applications

Stock Preparation
Primary and secondary screening stages in stock prep lines
Broke System
Efficient screening of broke pulp for reuse in paper production
Approach Flow
