Abstract
An apparatus for supplying a constant amount of abrasive which can supply even dry ice particles, ice particles, or the like as abrasive in a constant amount is provided. In order to take out abrasive contained in measuring holesof a rotating disc, an abrasive mixing sectionfor blowing a compressed gas into each of the measuring holeshas a cylinder' which opens toward one surface of the rotating disc at the position where the measuring holes are formed. A piston′ is inserted into the cylinder. A fluid channelopens toward the cylinder′ through the intermediary of the rotating discand whose opening rimis in sliding contact with another surface of the rotating disc. One of the cylinder′ and the fluid channelcommunicates with a compressed-gas supply source through the intermediary of a compressed-gas introduction path. The other one of the cylinder′ and the fluid channelcommunicates with the abrasive transport path. The piston′ has a through-holepassing therethrough in such a manner as to coincide with the position where the measuring holes are formed.
