Abstract:
1. In a separator system wherein particulate material is introduced into a separating zone in a housing and separated therein into relatively fine and relatively coarse particles, and wherein gas is introduced from a source thereof to said separating zone independently of said particulate material for movement through said separating zone in a stream at such velocity as to entrain in said stream at least a portion of said relatively fine particles and conduct said portion of said relatively fine particles to a fine particles collector downstream of said separating zone via conduit means extending between and in communication with said separating zone and with said collector, the improvement comprising: a) a generally horizontal gas passageway means formed by a duct external of the housing and upstream of said separating zone in communication with said source and with said conduit means and bypassing said separating zone; and b) adjustable diverter means for diverting a selected portion of said gas stream from said source into said generally horizontal passageway means upstream of said separating zone and from said generally horizontal passageway means into said conduit means downstream of said separating zone and upstream of said collector.
