Abstract: A portable particulate grader includes a grader body assembly and a grader tray assembly. The grader body assembly includes an upper housing including side portions, a plurality of springs, a lower chute, a dust control gate, and wheels. The springs are disposed on an inner portion of the upper housing, and hold a grader tray assembly in an angle and provide vibrations to the grader tray assembly. The grader tray assembly includes a grader tray frame, a detachable mesh disposed on the grader tray frame, an upper chute, and a residual control gate. A method for grading particulates includes introducing the input material to the detachable mesh, providing vibrations non-electrically to the grader to separate the input material into a filtered material and a residual material, opening the dust control gate to retrieve the filtered material, and opening the residual control gate to transfer the residual material.

Abstract: A base supports an inclined screen having a uniform mesh selected to remove larger aggregate from a first cement mixture to form a second cement mixture that passes through the screen. A powered vibrator vibrates the screen to separate the concrete mixtures and larger aggregate. Springs and/or dampers in support legs isolate the vibrating screen from the base. A guide frame on the top surface of the screen guides the first concrete mixture along the screen and guide the separated aggregate out a bottom opening into an aggregate container. A support frame on the bottom surface of the screen stiffens the screen to help support the weight of the concrete. A concrete container, preferably wheeled, is below the screen to collect the second concrete mixture and move it to its use location.

Abstract: The apparatus and method provide for the removal of well fluids from well cuttings and a method of disposal thereof. A vibratory separator mechanically shakes the well fluids from the cuttings into a first compartment and the well cuttings fall into a second compartment. Once the well cuttings are dried, cement kiln dust (CKD) is added to neutralize any remaining well fluids on the well cuttings. The neutralized well cuttings are applied to the roadbed of a gravel or dirt road.
