Dust generation measuring device and dust generation measurement method using the same

摘要

PROBLEM TO BE SOLVED: To provide a dust emission measuring device that realizes sure application of a tumbling method even when a specimen is lightweight.SOLUTION: A dust emission measuring device 100 according to the invention comprises: a hollow cylindrical rotary drum 130 that is provided with an air inlet 130AI and an air outlet 130AO, can store a specimen S inside and realizes dust emission from the specimen S through rotation operation with setting a horizontal direction as a rotation axis; a clean air supplying part 110 that supplies clean air to the air inlet 130AI of the rotary drum; and a dust measuring part 150 that is arranged on a downstream of a flow channel of the clean air from the air outlet 130AO and measures the dust. An open bottom surface 130B2 of the rotary drum 130 is provided with the air outlet 130AO, at least part of a cylindrical surface 130S of the rotary drum is provided with the air inlet 130AI and the air inlet is mesh-like.SELECTED DRAWING: Figure 2
