The simplest recovery system available is the hopper elevator recovery system. This is available in two versions.
The “below floor” version incorporates a 900mm x 900mm hopper feeding an elevator set in a pit. Used abrasive is swept or tipped into the hopper.
The “above floor” version does not need a pit. Used abrasive is shovelled into the elevator through an opening in the blast chamber wall.
Like all the Protoblast full and partial recovery systems the hopper elevator recovery system incorporates an abrasive separator for efficient cleaning of the used abrasive.
