  • Patent number: 8926406
    Abstract: A rotor assembly is provided for blast processing. The rotor assembly includes multiple lofting elements to create a vortex to loft particulate material to be used to process a target, and multiple elements to project the particulate material toward the target. The rotor assembly is enclosed within an operating chamber that has a target area into which the particulate material is projected to strike the target. There may further be angled deflectors at the opening to direct particulate material back toward the rotor assembly to use the material for further processing. Certain components are easily adjustable for different sizes and shapes of target. The action of the rotor assembly enables the use of up to 100% pure grit for entire cleaning processes, and provides single pass hook profile on any common material surface.

  • Patent number: 8920217
    Abstract: A method and apparatus for connecting a blade to a single sided wheel plate or a pair of interconnected wheel plates. The assembly provides a repeatable, positive and even positioning location for each blade. It utilizes an ellipse that tapers outwardly from the center of the wheel along the blade connecting member that corresponds with the connecting channel on the wheel. The ellipse provides for equal and uniform contact on the entire blade connection to firmly hold the blade in place without parallel surfaces. The ellipse design provides a measured and increasing improved release in that all surfaces of the ellipse are tapered with non-parallel surfaces such that blade retention and blade removal is dramatically simplified.

  • Patent number: 8702476
    Abstract: A machine for centrifugally shooting abrasives that shoots the abrasives by rotation of an impeller is provided. In the machine, the impeller comprises a pair of disc-shaped side plates that face each other at a predetermined distance and a plurality of blades disposed between the side plates in the radial direction of the side plates. The impeller is mounted on a hub that is fitted into an output shaft of an electric motor. The impeller is covered by a cover. The side liner and blades of the machine can be easily replaced. A side liner 3 that is U-shaped with the longer side facing downward is detachably attached to the inner side of the cover 2. The upper part of the side liner is divisible into two parts. The side liner protects the side wall of the cover 2 from the abrasives that are shot from the impeller. The side liner has a U-shaped cross section. The impeller 1 is fixed to the hub 4 by screwing a bolt 15 on the hub 4 from the inner sides of the side plates 11.

  • Patent number: 5888125
    Abstract: In accordance with the teachings of the present invention, an abrasive blast wheel is assembled for cleaning work pieces with abrasive materials. The blast wheel assembly is simplified by securing the blades about the impeller by inserting them into slots in a blade supporting wheel and retaining them therein with a retaining ring that extends over the outer edge of the wheel. Removal and subsequent replacement of the blades is thus simplified because all of the blades may be removed simultaneously by merely removing the retaining ring.

  • Patent number: 5833521
    Abstract: A blast head has an air cushion device that directs a flow of relatively high velocity air inwardly and toward the surface being blasted from around the periphery of the blast head. This air flow creates a barrier preventing the escape of particles and debris from the blast head and also creates a so-called ground effect; i.e. the air flow between the head and the surface creates a force that lifts the head off the surface being blasted so that the head floats on cushion of air.

  • Patent number: 5779524
    Abstract: An adjustable cage assembly for selectively varying the path of abrasive in an abrasive blast swath produced by a mobile surface abrading apparatus. The adjustable cage assembly operates in cooperation with a rotable wheel having multiple, radially-extending blades positioned in a wheel housing. A cage having a cage window extends into the center of the wheel and an impeller having multiple impeller slots is positioned in the cage for rotation with the wheel, and receives a supply of abrasive particles such as steel shot, from the apparatus. As the impeller and wheel are rotated and the abrasive is continually fed into the impeller, the abrasive is discharged through the rotatably aligned impeller slots and the selectively-positioned cage window, and is propelled by the rotating wheel blades through the abrasive discharge opening to abrade, clean or etch the pavement.

    Abstract: A blast wheel assembly has a bladed rotor and an impeller which rotate together. A cage has an axial and angular wall including an aperture through which in use particulate material passes. The cross section of the aperture is irregular to control the uniformity of blast effect on a surface being treated. The assembly can be in a mobile or static machine. Various forms of aperture are described, the preferred form of which is of non-uniform shape as it extends angularly with respect to the cage axis, the aperture being of less cross-section in a region intermediate the angular end regions of the aperture.

    Abstract: This invention relates to a method of releasably connecting a blade to a single wheel plate of a centrifugal blasting wheel without using a separate stop-member to prevent outward radial movement of the blade. An alternative method of releasably connecting a blade to a wheel plate, and an alternative blade, wheel plate and blasting wheel are provided. The invention is useful in releasably aligning blades without the use of stop members. The blade can be accurately aligned in the channel of the wheel plate as a result of positive abutment of the sides of a wedge on the blade against the sides of the channel.

  • Patent number: 5472369
    Abstract: A cryoblasting process having a centrifugal accelerator for accelerating frozen pellets of argon or carbon dioxide toward a target area utilizes an accelerator throw wheel designed to induce, during operation, the creation of a low-friction gas bearing within internal passages of the wheel which would otherwise retard acceleration of the pellets as they move through the passages. An associated system and method for removing paint from a surface with cryoblasting techniques involves the treating, such as a preheating, of the painted surface to soften the paint prior to the impacting of frozen pellets thereagainst to increase the rate of paint removal. A system and method for producing large quantities of frozen pellets from a liquid material, such as liquid argon or carbon dioxide, for use in a cryoblasting process utilizes a chamber into which the liquid material is introduced in the form of a jet which disintegrates into droplets.
