摘要： An apparatus for removing ground dust from the surface of a grinding wheel (1,38,45,55) including a blasting apparatus (9,31,47,57) for application in a dry grinding process of ceramic work piece (7,39,52,60). The blasting apparatus (9,31,47,57) blasts abrasive grains against the surface of the grinding wheel (1,38,45,55). A circulating passage (13,33a,33b), both ends of which are connected with the blasting apparatus (9,31,47,57), receives the abrasive grains in the vicinity of the apparatus and returns them to the blasting apparatus (9,31,47,57). By such process, the grinding of the work piece (7,39,52,60) and ground dust removal from the surface of the grinding wheel (1,38,45,55) can be accomplished simultaneously, efficiently and speedily. Further, the blasted abrasive grains are recovered and recycled, enabling a reduction in grinding process costs.
