Productstructure:Johnson screen isarranged in parallelwith the verticalwiremeshsievesupportstripbarswelded together,cross-sectional shapeof theV-shapedsieve, meshstripabovetheplane.The lower endissharp,thatconfluencespot weldingeachsupport bar.
Features:
1, high strength.V-shapedcross-sectionalheightgreater than the widthof thescreen,meshstripitself hasa certain strength.The screen barsin contact with thesupport barofeach pointis fixed by welding,so that allthe screen barsto formasolidwhole.
2, theopening rate.Openingrate is generallyporous platedoes not exceed30%,sincethe openingholebridgebetweena certainwidth, butJohnsonnetworkisnot so limited,the holeis tobridgeJohnsonsievemeshstrips,Since theprocessing methodand thecross-sectional shapeof thescreento make iteasy to break,can takeallspansa relatively narrowsize,reducingthe width ofthe screen barsor expandedgapbetween thescreen bars,the opening ratiocan be improvedJohnsonnetwork.
