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