Investigation of the dispersed composition of dust of inert materials exposed to overload in the manufacture of building materials

Abstract

Abstract At enterprises for the manufacture of building materials, when pouring bulk components, there is an intense emission of dust into the air of the working area of the room. The article presents the results of the dispersed analysis of dust when pouring cement, crushed stone, silicate bricks and chalk, and the integral functions of the distribution of dust particles by diameter are constructed. According to the criteria of Lyashchenko and Reynolds, the results of the sedimentation rate of dust particles were theoretically obtained. Measures are given to reduce the dust content of the air in the working area of the shop.
