Abstract:
A screening system for screening particulate material comprising:a screening assembly including a housing defining an interior screening chamber, the screening assembly having a longitudinally-extending axis and a laterally-extending axis;support members located within the confines of the interior screen chamber and joined to the housing for supporting said screen assembly;a frame member for supporting a plurality of screening modules attached thereto;a plurality of screening modules mounted for direct attachment to and removal from the screening assembly, each screening module comprising means defining an array of sieve apertures of a predetermined size for allowing particulate material up to the predetermined size to pass through the screening module, the screening module being positioned on the frame so that particulate material passing through the screening module passes through the frame; anda self-interlocking protective covering system for shielding said at least one of said support members and said frame member resulting from impact and frictional engagement caused by the flow of aggregate material during the screening process thereby avoiding substantial wear problems to said at least one of said support members and said frame member, the protective covering system being readily removable from said support members and/or said frame member to minimize production downtime and to facilitate effective and efficient attachment and removability from either one of said support members and said frame member.
