Abstract

Provided is a shot processing apparatus capable of suppressing scattering of projection materials to the outside without causing any deterioration in projection efficiency. The shot processing apparatus comprises: a cabinet; a drum housed in the cabinet and having an opening allowing loading of a workpiece therethrough, wherein the drum is configured to be selectively disposed in one of a workpiece-loading position, a workpiece-processing position and a workpiece-unloading position; a projector for projecting the projection materials into the drum; and a door for selectively opening and closing the opening of the drum, the door being formed with a projection port for the projection materials, the projector being attached to the door so as to project the projection materials from the projection port; wherein the door is configured such that the projection port is disposed just above the opening of the drum when opening the opening of the drum.
