This is bob from haixing wedge wire company in china. Haixing All Welded V-Wire Flat Screens are used for wide range of applications such as sizing, classification and de-watering.These are used for coal & iron ore beneficiations when fitted on the vibratory machine.There are three basic reasons why our stainless steel screen panels are so widely used in mineral processing vibrators .Effective sizing or classifying requires uniform slots in the screen..The screen panels in flat deck applications are made with rectangular support bars which enables the panel to span longer distances without intermediate support bars.Welding each surface wire at every junction with support rods creates a rigid structure that transmits vibratory forces more effectively with less energy loss.Haixing screen panels are manufactured with an edge finish and variety of framing methods to suit your various needs.Please tell us your demand and then we design ,manufacture for you.Yours faithfully bob.
