SURFACE POLISHING DEVICE OF PARTICULATE MATTER

摘要

PURPOSE:To effectively make the surface of particulate matters smooth by positively flowing the particulate matters below a rotary grinding wheel fixed with grinding abrasive grains on its periphery. CONSTITUTION:A rotary grinding wheel fixed with grinding abrasive grains on its surface is positively driven at the lower section of a case 10 and angular particulate matters 9 to be processed are flowed at its lower face. A protective plate 5 is arranged at the bottom of a case, and a breather pipe 13 is arranged upstream the case to apply a flow to the particulate matters 9 and air is blown in toward the downstream side of the particulate matters 9. Dust is collected into a duct through the upper section of the case. 8, 12 are feed port and a discharge port of the particulate matters 9 respectively.
