An object-sorting apparatus includes a housing that extends from a top end to a bottom end, at least one vibration element, and a plurality of stages arranged in a vertical sequence in the housing between the top end and the bottom end. At least one of the stages includes a sorting base that at least partially defines a floor of the at least one stage. The sorting base is coupled to the at least one vibration element, and is configured to receive thereon a mixture of objects having different sizes, including a target size associated with the at least one stage. The stage also includes apertures defined in and extending through the sorting base and into flow communication with a next lower stage. The apertures are sized to receive therethrough, from the mixture, objects having a size smaller than the target size associated with the at least one stage.

A flip-flow screener machine includes a carrier frame with primary, drive-induced vibration, to which a vibrating frame is coupled in a freely oscillating manner by means of elastic transmission elements and is excited and set to vibrate secondarily by the carrier frame via said transmission elements, transverse carriers being arranged on the carrier frame and on the vibrating frame, a transverse carrier on the vibrating frame lying downstream of a transverse carrier on said carrier frame, with a flexible screen bottom being arranged between two transverse carriers and detachably secured to said transverse carriers, each of the screen bottoms including at least one undercut portion by means of which they can engage behind an undercut on the transverse carrier, and two adjacent screen bottoms abutting one another directly at their front ends.

A minerals processing unit, such as a vibrating screen (10), is described. The vibrating screen (10) comprises a sensing mechanism operable to detect: (i) motion of the vibrating screen (10) in multiple directions, and (ii) detect planar deviations of a mesh surface (22). The sensing mechanism may comprise a plurality of discrete sensors (60-66), including a gyroscopic sensor (60) operable to detect linear movement in three mutually orthogonal directions, and one or more of roll, pitch, and yaw. The sensing mechanism may further comprise a temperature sensor (64a, 64b) for measuring the temperature of a drive mechanism (42) and an ambient temperature sensor (66a, 66b) for measuring a control value to compare with the drive mechanism temperature.
