Abstract

A dust explosion occurs when particles suspended in the air ignite and
burn rapidly, causing a violent increase in pressure. In the production
procedure of feeds considerable quantities of fine dust particles are
produced which are exceptionally dangerous for the creation of explosive mixture. Physical properties of grain dust derived from three grain types (wheat, corn, soybean) were measured and reported. The grain dust samples were obtained from dust collection systems in feed factory. The physical properties reported were as follows: share of dust fractions under 100 µm of all the dust, bulk density, particle size distribution and surface area measurements.
Implementations of laboratory procedures in analyses of potential
explosive danger (distributions of particles < 100 µm, densities and the surface area of particles) represent the unused system for the development of explosion indicators and a very important element in the development of the system and equipment for the dedusting and the transport of feeds.
