Abstract
This shredder-mixer-distributor trailer comprises an elongated box-like container longitudinally accommodating lower and upper rotating scrolls. The lower scrolls are arranged mutually close and convey material toward the front portion of the container, while the upper scrolls are spaced apart from each other and transport the material in the opposite direction. The lower scrolls define spirals with constant height and have two vertical baffles interposed therebetween. The upper scrolls define a variable-height spiral with portions extending along opposite directions. The container longitudinally accommodates wedge-like elements for adjusting the feed to the lower scrolls and avoiding accumulation of material toward the walls of the container, and toothed-blade elements for improving shredding and keeping the scrolls clean. A loading bucket is integrated in the rear portion of the container while front doors allow unloading of the shredded material.
