The action of the Kani Karan Asia Wilfley Laboratory shaking table duplicates that of the commercial units and laboratory results can be accurately reproduced in large scale commercial operation. This laboratory table is also used extensively as a pilot table to indicate the efficiency of a flotation circuit. Table consists of a linoleum or rubber-covered deck mounted on a steel channel under structure, with enclosed self-oiling head motion, improved draw bar, and a positive tilting device. Improved design of feed box allows maximum classification of product on concentrating table. For use in batch operations, a set of special product pans has been designed for catching the middling, concentrates, and tailings. These contain small supplementary pans which can be shifted for cutting samples.
