Method and apparatus for removing excess material from sand cores |
摘要 |
A method and apparatus for removing flash and other excess material from sand cores in which the cores are showered with impact particles of relatively soft material and contained in moving air streams issuing from a plurality of nozzles directed against opposite sides of cores being cleaned. Low pressure air from a blower is used at the nozzles to obtain a high density of particles in the moving air stream and provide for engagement of the particles in a gentle manner with the sand cores so as to minimize surface erosion of the cores.
