Abstract: A vibrating screen apparatus for sizing materials is shown that has a minimum of moving parts therein. A vibrating motor is mounted below longitudinal vibrating rails. The vibrating rails rest on top of shoes attached to air mounts, which air mounts are between the vibrating rails and cross braces connected to the frame. The shoes are located inside of angled clips and attached on the underside of the vibrating rails. The angled clips hold the vibrating rails in position. The vibrating rails press against the underside of a vibrating screen to form a crown therein when the air mounts are inflated. The vibrating screen is stretched between the sides of the frame by tensioning rails. Multiple size materials can be produced by stacking multiple vibrating screen apparatuses. Access is provided to lower vibrating screens by pivoting upper vibrating screens out of the way.
