Abstract

PURPOSE:To size dust surely and perform sizing of high accuracy by setting the inside diameter of a smapling nozzle slightly larger than the inside diameter of an accelerating nozzle, and the spacing between the end edges where said nozzles oppose to each other slightly smaller than the inside diameter of the nozzle. CONSTITUTION:Air contg., for example. dust, which is a measuring object, is sucked through a sampling port 1 by the operation of each pump, and is sucked into a sizing device 4 past an acceleration nozzle 2. If in this case the ratio of the inside diameter A of the nozzle 2 to the inside diameter B of the nozzle 3 is set at, for example, approximately 1, 3 and the ratio of the nozzles 2, 3 at, for example, approximately 0.89, and further the flow rate ratio of the sampling air flow rate Q of the port 1 and the suction flow rate Q1 of a suction pipe 6 at, for example, approximately 0.1, the desirable results of sizing is obtained, hence the calibration of extremely high accuracy is accomplished.
