Abstract: Disclosed herein is a rolling screen assembly. The rolling screen assembly may include a frame, a screen assembly mounted to the frame, a wheel assembly mounted to the frame, and a foot affixed to the frame, where wheels of the wheel assembly are height adjustable relative to the frame to allow the foot to be raised from, and lowered onto, a support surface. Such assembly may facilitate replacement of a rolling screen assembly with minimal downtime.

Abstract: Disclosed herein are embodiments of a vibrating screen (10) for separation of materials such as ores in mining, quarrying, and mineral processing. The vibrating screen (10) herein disclosed may include a chassis (100) with two side walls (102) with a plurality of support members (104) therebetween and a screen mounting system that receives screen panels (120). At least one of the side walls (102) may have a recess (132) that receives a protrusion (160) of a mounting plate (114) of a vibrator (126).
