CONTOURED WIRECYLINDERCONTOURED WIRE CYLINDERS HELP IMPROVE THESCREENING EFFICIENCY OF SCREENING SYSTEMS.Johnson Screens provides all modelsof inflow and outflow pressure screencylinders.We offer slot widths down to 0.004 in.(0.10 mm), wire width down to 0.079 in.(2.0 mm) for 12 spi, and multiple contourdepths are offered.And we offer pressure screens to suitmany different types of machines.OutflowInflowJohnson Screens has made extensiveresearch in cylinder designs and wirecontour design shapes. We focus onthe optimum designs and wire shapesto provide cylinders that run with allrotor designs and pulp variations.Because of the many installed wirecylinders, the facts show that it hasbecome the optimum cylinder tobe installed in any pulp and paperpressure-screen system.Surface wear is a common cause offailure of milled and wire cylinders.It is important to protect the surfacefrom wear due to the high levels ofdebris found during the screeningprocess. Johnson Screens uses aspecial chroming process to increasethe thickness of the protective chromelayer and ensure a high hardnessquality. Depending on the amountof debris, typically thicknesses are0.006 in., 0.012 in. and 0.018 in.(0.15 mm, 0.30 mm and 0.45 mm).The results are a well-protected surfaceand less frequent cylinder replacement.04
