1. A portable recirculating crushing plant, comprising:
a portable chassis;
a feeder supported on said chassis, said feeder having a discharge end;
a crusher supported on said chassis, said crusher comprising a horizontal shaft impact crusher, said crusher having an upward-facing feed inlet in an upper portion thereof to receive material deposited vertically therein, said feed inlet being separate and spaced apart from said feeder discharge end, said discharge end of said feeder being positioned to deposit material into said feed inlet of said crusher;
a vibratory classifier supported on said chassis;
a first conveyor disposed to convey material from said crusher to said vibratory classifier;
a cross-conveyor disposed to receive material from said vibratory classifier;
a pivot arm pivotally supported on said chassis for pivoting relative to said chassis about a vertical pivot axis A; and
a second conveyor disposed to receive material from said cross-conveyor, said second conveyor having a head end and a tail end, said second conveyor having a length, said second conveyor having a chute supported thereon, said chute being disposed to receive material deposited from said cross-conveyor, said chute having a chute outlet, said second conveyor having a transport configuration and an operating configuration, said second conveyor being pivotably supported on said pivot arm for pivoting relative to said pivot arm about a pivot axis B, said pivot axis B being generally parallel to said vertical pivot axis A, said pivot axis B being spaced apart from said vertical pivot axis A, whereby said second conveyor is pivotable about vertical pivot axis A and pivot axis B, said second conveyor being pivotable between said transport configuration and said operating configuration, wherein in said operating configuration, said tail end is disposed at least partly beneath and adjacent to said cross-conveyor to receive material from said cross-conveyor, wherein in said operating configuration, said second conveyor is oriented to convey material in an at least partially inboard direction, wherein in said operating configuration, said length of said second conveyor is such that said chute is disposed to guide material directly into said feed inlet without contacting said feeder, wherein in said transport configuration, said tail end is closer to said chassis than in said operating configuration, and wherein in said transport configuration, said head end is disposed outboard of said crusher, wherein said crusher is disposed such that second conveyor is able to pivot into said operating position with said head end above said crusher without interfering with said crusher.
