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 linerthat is U-shaped with the longer side facing downward is detachably attached to the inner side of the cover. The upper part of the side liner is divisible into two parts. The side liner protects the side wall of the coverfrom the abrasives that are shot from the impeller. The side liner has a U-shaped cross section. The impelleris fixed to the hubby screwing a bolton the hubfrom the inner sides of the side plates. The diameter of the impelleris limited to be 200 mm at maximum.

Machine for centrifugally shooting abrasives

A centrifugally projecting apparatus is provided to allow a liner to be easily exchanged, to prevent projecting members from projecting through the connected parts of the liner components, and to prevent an impeller cover from being abraded. The apparatus comprises bolts and a fixing member (hook members ) to press first and second-side liner components A, front and rear-side liner components A, and a frame-liner component against a ceiling-side liner component so that they are fixed to each other.
