The temperature of the chamber housing a shot wheel of a shot blaster is controlled by positioning a fan exterior to the chamber that creates air flow across a mounting plate defining the chamber. The air flow created by the fan may also pass around the bearing surrounding the drive shaft that turns the shot wheel.

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.

First guide pipes are disposed on both sides of blasting areas, and second guide pipes are disposed on both sides of the blasting area. A wire rod W is inserted through the first guide pipes and the second guide pipes, penetrating in a conveying direction of the wire rod W. The diameter of each of first insertion holes of the first guide pipes and second insertion holes of the second guide pipes is gradually reduced toward the downstream side in the conveying direction. The second guide pipe is installed in a state in which the downstream-side end portion in the conveying direction is inserted into the first insertion hole from the inlet side of the first guide pipe.

The temperature of the chamber housing a shot wheel of a shot blaster is controlled by positioning a fan exterior to the chamber that creates air flow across a mounting plate defining the chamber. The air flow created by the fan may also pass around the bearing surrounding the drive shaft that turns the shot wheel.

A shot blasting cabinet with adjustable impellers includes a cabinet, a plurality of impeller apparatuses, and a plurality of adjusting devices. A shot-blasting working line is defined between an inlet and an outlet of the cabinet. The impeller apparatuses are symmetrically disposed on upper and lower sides of the cabinet. Each impeller apparatus has a protective housing, a driving device, a pair of rotary plates, and a plurality of impeller blades. The driving device connects one of the rotary plates. The protective housing covers the pair of rotary plates and the impeller blades, and defines a shot-blasting exit surface. The shot-blasting exit surface communicates with an interior of the cabinet. The adjusting devices are used to adjust an angle and a distance of the shot-blasting exit surface relative to the shot-blasting working line.
