Summary:The present invention relates to a releasable characteristics assessment apparatus in the grinding of a material. The purpose of the present invention is to provide the releasable characteristics assessment apparatus used for objectively and accurately assessing the releasable characteristics of asbestos fibers in a grinding process after spraying a stabilizer for preventing content materials like the asbestos fibers from being scattered with regard to various construction materials of sprayed fire resistive materials, ceiling materials, and roof materials. For achieving the purpose, disclosed is the releasable characteristics assessment apparatus in the grinding of the material which includes a chamber which includes an inner space which is sealed, an object holder which is installed on the upper side of the inner space of the chamber and mounts an object which is a material specimen of a test target, a dropping device which is installed on the upper side of the inner space of the chamber and grinds the object by dropping a falling weight on the object mounted on the object holder, an electric fan for scattering the scattering materials included in the object in the grinding of the object through a ventilation in the inner space of the chamber, and a collecting device which collects the scattering materials which are scattered in the air by sucking the inner air of the chamber. 본 발명은 자재 파쇄시 비산성 평가 장치에 관한 것으로서, 내화뿜칠재, 천장재, 지붕재 등의 각종 건축자재에 대해서 석면섬유 등의 함유 물질이 비산되는 것을 방지하기 위한 안정화제를 도포한 후 파쇄할 때 석면섬유 등의 비산 유무를 정확하고 객관적으로 평가하는데 이용할 수 있는 비산성 평가 장치를 제공하는데 그 목적이 있는 것이다. 상기한 목적을 달성하기 위해, 밀폐 가능한 내부공간을 가지는 챔버; 챔버 내부공간 하부에 설치되어 시험 대상의 자재 시편인 시험체가 장착되는 시험체 거치대; 챔버 내부공간 상부에 설치되어 시험체 거치대에 장착된 시험체에 낙하추를 낙하시켜 시험체를 파쇄하는 낙하 장치; 챔버 내부공간에서 송풍을 통하여 시험체 파쇄시 시험체에 함유된 비산 물질을 비산시키기 위한 전동팬; 및 챔버 내부 공기를 흡입하여 공기 중에 비산되어 있는 비산 물질을 포집하는 포집장치를 포함하는 자재 파쇄시 비산성 평가 장치가 개시된다.
