Abstract: A hydraulic separation system and method enables efficient recycling of log yard waste from an elevated frame. The system separates fine granules, small rocks, small bark, large bark, and large rocks with a variety of sequentially positioned, hydraulically powered separating components. The separation is mechanical and the size and weight of the individual material determines where in the system it is separated. Conveyors carry the log yard waste through the system. Shaking screens shake in a fast, up and down motion to flip and move the material through the system. Adjustable sloped plates work to accelerate and decelerate the material through the system. Dampening fingers control the disposition of elongated pieces of large bark and help to decelerate down the material. Blowers separate the bark from heavier rock and granular material. The elevated frame to enable cleaning and access to materials discharged beneath the elevated frame.
