The purpose of the present invention is to provide a shot processing device and a projector such that the projection amount of a projection material can be minimized. The present invention provides a shot processing device equipped with a centrifugal projector for projecting a projection material onto a workpiece and a support mechanism for supporting the workpiece at a processing position where surface processing by the projector can be carried out, wherein the projector is equipped with: a cylindrical control cage which the projection material is supplied into and which has an opening formed on a side wall as a projection material discharge port; and an impeller that has a plurality of blades, which are arranged outside of the control cage and extend outward in the radial direction of the control cage, and rotates about the central axis of the control cage, wherein each blade has, disposed on a front-side surface in the rotation direction, a rearward inclined section inclining toward the rear-side in the rotation direction.

The separation apparatus for separation of material from a liquid includes a tank (10) through which the liquid can be passed and a conveying device (20). The tank has a bottom (10c) on which material collects during operation. The conveying device has a conveying element (21) that can be moved along the bottom (10c) by a drive (25). The conveying element is set up for picking up material that has collected on the bottom and for conveying it out of the tank (10).

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.

Systems and methods treat sucker rods in a machine through a multi-step process. Initially, sucker rods are cleaned before being conditioned. The conditioning process involves using a defined type and a defined size of media, applied at a first intensity to the rods using first media accelerators (first wheels with a specific diameter and rotational speed, and/or imparting a certain amount of media). The conditioned surfaces are then shot peened at a higher intensity using second media accelerators, which can have larger diameters, faster rotational speeds, and/or can impart a greater amount of media. Both the conditioning and shot peening processes involve reclaiming the media for reuse.

An apparatus for treating a surface of an object is disclosed, including a carrier configured to transport the object through a treatment zone and an array of nozzle devices, each nozzle device positioned to deliver a cavitating jet into the treatment zone. The apparatus further includes a fluid source, a pump connected to the fluid source, and a hose configured to carry fluid under high pressure generated by the pump from the fluid source to the array of nozzle devices.

An apparatus to remove at least a portion of a coating from a coated surface of a substrate may include a nozzle assembly and one or more nozzle-heads. Each nozzle-head may include at least one nozzle tip and a cavity configured to receive a portion of the coated surface of the substrate. The nozzle tip may be configured to direct an angled stream of an etchant on the substrate as the nozzle assembly moves along the length of the substrate. One or more sensors may measure a warpage of the substrate along the length of the substrate, and a controller may move the nozzle-head orthogonal to the direction of nozzle-head movement based on the measured warpage.

A blasting container for blasting workpieces with blasting medium has a wall that is provided with outlet openings for blasting medium. Covers are located at the outer side of the wall above the openings.
