A vane for insertion into a slot of a wheel of a blasting assembly such that the vane propels media as the wheel is rotated includes a body radially extending between a first vane end and a second vane end, between a first flange and a second flange, and having opposing vane side surfaces. An attachment portion integral with the second flange, the attachment portion configured to be received into the slot, and the attachment portion having a first vane end retaining surface and a second vane end retaining surface that are configured to abut the wheel. The first vane end retaining surface and the second vane end retaining surface are adjacent to each other, the first vane end retaining surface is convex, and the second vane end retaining surface is concave.

A shot blasting wheel for use with a shot blasting machine configured to propel abrasive shot against a workpiece. The shot blasting wheel includes a circular body member defining a plurality of slot openings a front surface defines a plurality of slots. Each slot and slot opening has a dovetail configuration. The shot blasting wheel includes a plurality of blade assemblies, each including a paddle positioned in a respective slot via insertion through a respective slot opening. Each blade assembly also includes a locking lever pivotally coupled to the body member and pivotally movable between a locked configuration preventing removal of the paddle from the respective slot and a released configuration allowing removal. Further, each blade assembly includes a dual spring assembly having a lever spring tensioned and biased for movement between extended and released configurations and having a paddle spring configured to resist a paddle lug.

The subject of the invention is an abrasive blast machine for surfaces of large-scale workpieces comprising a housing (O) constituting a working chamber, a kinematic mechanism for moving the effector, an abrasive recirculation system, an effector feeding system with recirculated abrasive, characterized in that the kinematic mechanism is a multipart kinematic mechanism (MK) with at least four-axis, and in that, the effector is an impact turbine (T), which produces the treatment tool and directs it to the workpiece.

A twist-lock assembly for locking and unlocking a feed spout and control cage in their respective operative positions on a centrifugal blasting wheel. The twist-lock assembly includes a stationary control cage adapter and a rotatable clamping plate. The control cage adapter is mounted on a side wall of the centrifugal blasting wheel housing and located at an access opening in the housing. The clamping plate is rotatable with respect to the control cage adapter for locking and unlocking the control cage and the feed spout in their respective operative positions in response to rotation thereof between a clockwise locking position and a counterclockwise unlocking position. The result is an improved assembly for quickly dis-connecting and re-connecting the feed spout and control cage to provide ease of maintenance.

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.
