Abstract: A portable screening and washing assembly includes a frame, and in addition, a scrubbing mill, a vibratory screen assembly and a fine material washer, all of which are mounted on the frame. Both the scrubbing mill and the fine material washer are adapted to move between a transport configuration and an operational configuration.

Abstract: A tank assembly for classifying and blending sand products. The tank assembly includes a receptacle adapted to retain slurry at or below an upper level. The receptacle includes a feed end having a receptacle inlet, a discharge end having a receptacle overflow outlet, and a pair of side walls extending between the feed end and the discharge end. The discharge end of the receptacle is generally opposed to the feed end. The tank assembly also includes a plurality of upper cross tubes mounted to and extending between the pair of side walls of the receptacle. Each of the plurality of upper cross tubes is disposed above the upper level of the receptacle. The tank assembly further includes a plurality of settling stations mounted in the receptacle. Each of the settling stations includes an adjustable height sensing paddle adapted to control the amount of slurry that accumulates at the station, a discharge valve, and a slurry discharge pipe.

Abstract: An apparatus and method for removing lightweight particulates during processing of a primary material. The apparatus includes a classification tank having an inlet, an outlet and a plurality of settling stations located therebetween. A slurry of fluid and particles is introduced into the inlet and directed towards the outlet. As the slurry traverses along the classification tank, particles come out of suspension at the settling stations according to weight and to a lesser degree, density. The composition as well as the quantity of particles at the settling stations is periodically inspected. If particles deposited at a particular settling station are more or less the same size, and if they have accumulated in sufficient quantity, they are discharged to a flume which directs them to preselected collection areas.
