Abstract
A mobile material screening apparatus includes a sloped screen box, a housing, a fifth wheel coupling, an engine and a pair of wheels fixed to the housing. Two hydraulic rams lift the apparatus and wheels off the ground and four extendable legs support it off the ground. A conveyor located underneath the screen box delivers fully screened material up over the fifth wheel coupling. A second conveyor located at the side of the apparatus removes second grade screened material. A third conveyor removes reject material which comes down a chute.
