A shot-processing device is provided, and by it they are effectively reused and prevented from being taken out of a cabinet and from scattering. A structure (40) for a flow path that connects the inside of the cabinet (12) and a suction port (70A) of a dust collector (70) includes a part of a route for circulation of a circulating machine (32) and a second flow path (40Y) that connects a chamber for blowing air and the suction port (70A). In the structure for the flow path a classifying part (35) is provided. It includes a first cyclone (36) that classifies particulate objects that include shots as shots that have a diameter that makes them reusable and as the other particulate objects and includes a part of the first flow path (40X), and a second cyclone (44) that includes a part of the second flow path.

A shot processing device according to an aspect includes: a guide portion provided in a conveyance direction of a workpiece; a rotation mechanism which includes a first endless belt providing a placement surface having the workpiece placed thereon and a first drive unit driving the first endless belt so that the placement surface moves in a direction opposite to the conveyance direction; a conveyance mechanism which pushes the workpiece toward the conveyance direction so that the workpiece on the placement surface rolls and moves in the conveyance direction along the guide portion; and at least one projector which projects shot media to the workpiece rolling and moving on the placement surface.

A sand blaster is provided that includes an engine carried by an engine mounting plate. A frame is included and an engine support isolator engages the frame and carries the engine mounting plate. The engine support isolator has a stud that extends through a first coil and a stud guide that has a tapered inner surface. The stud extends through the stud guide. In other arrangements an air regulator that is adjustable is provided, and a nozzle that features reduced wear is provided.

A mobile steel grit dryer used to dry steel grit may be configured with a number of different functions and features to assist a contractor in performing steel or other structure maintenance when using steel grit in resurfacing the structure. The steel grit dryer may be configured with a heat process vacuum bypass so that an off-board vacuum, such as a vacuum on a grit recycling system, may be utilized as opposed to having an onboard vacuum. The dryer may include multiple modes so that an operator may use different modes for different environmental conditions. An exoframe may provide for better durability when being transported to different jobsites. A variety of automation and safety features may also be provided to simplify and improve safety for operators.
