Pressure Screen for Stock Screening

Name: Pressure Screen
Brand: Allwin Machinery

A pressure screen removes oversize contaminants from stock while the line stays under pressure, so it can sit inline without a break tank. Rotor type and cylinder slot size together decide both removal efficiency and how much good fibre you lose to rejects.

Technical questions

Pressure Screen — common questions

Should I use a slot cylinder or a hole cylinder?

Slots (typically 0.15-0.35 mm) for fine contaminant removal on recycled furnish. Holes (1.2-3.0 mm) where capacity matters more than fine screening. Most recycled lines run a coarse hole screen first, then a fine slot screen.

How do I keep good fibre loss down?

Match the rotor to the furnish and hold reject rate at roughly 3-8% of feed. Pushing reject rate lower than that usually trades fibre loss for debris in the accepts.
