Abstract

A modular device for abrasive particle blasting, a method of assembling a mobile abrasive particle blasting device, an apparatus for cleaning steel grit, and a method of cleaning steel grit are disclosed. The modular abrasive particle blasting device includes an abrasive particle storage component, an abrasive particle recovery component, and at least one subframe, adapted for carrying one of the components of the device. The subframe has a first vertical side defining a vertical boundary plane of the subframe and means for reversibly attaching the subframe at the vertical boundary plane to a second subframe structure. The reversible attachment between the first and second subframes is accomplished by providing a bolting pad on the vertical side for complimentary alignment with bolting pad on the adjoining subframe. A lifting attachment is also provided. An apparatus for cleaning steel grit includes a housing defining an enclosed space, an inlet into the housing, a vibrating perforated plate within the housing in line with the inlet, a first outlet of the housing, and a second outlet of the housing below the first outlet. Cleaning is accomplished by connecting the first outlet to a source of low pressure, feeding an entrained stream of grit, into the inlet of the apparatus, impacting the entrained stream of grit against the vibrating perforated plate to substantially dislodge any adhering dust from the grit.
