The present disclosure relates to methods and apparatus for separating excess slack out from a mixture of product and slack. For example, the slack could be a food product coating. According to one aspect, there is provided a hopper for diverting excess slack away from a mixture of product and slack, the hopper comprising a gate moveable between open and closed positions, wherein the gate is configured such that: when the gate is in the open position a first path is provided for contents of the hopper, comprising a mixture of product and slack, to exit the hopper; and when the gate is in the closed position the first path is closed by the gate so that product is retained in the hopper and a second path, different from the first path, is provided for slack to exit the hopper.

A shot peening efficiency system for separating reusable abrasive media from non-reusable media includes a housing having an opening configured to receive an abrasive media inlet valve; and a separator assembly disposed within the housing, the separator assembly comprising at least one mesh screen and at least one vibratory motor. The housing includes a main channel having a first channel for reusable abrasive media and a second channel for non-reusable abrasive media. The separator assembly is configured to separate reusable abrasive media from non-reusable abrasive media by passing the reusable abrasive media via the first channel and by passing the non-reusable abrasive media via the second channel. The first channel terminates at a reusable abrasive media outlet valve connected to at least one first abrasive media hopper; the second channel terminates at an abrasive media discard outlet valve connected to at least one second abrasive media hopper.
