Study of physical and mechanical properties of feed additives for cattle

Abstract

Abstract The article presents a study of the physical and mechanical properties of feed additives for cattle used in the farms of the Leningrad region. The choice of the investigated factors is due to their influence on the mixing process and design parameters of the mixer. When determining the particle size distribution, it was revealed that most of the materials under study have a particle size of d = 0.5-2 mm. The bulk density for most of the additives was 500-800 kg / m3. The moisture content of the main part of the investigated materials did not exceed 10%. The research results will make it possible to establish the influence of individual components on the property of the mixture and substantiate the optimal design and operating parameters of the mixer for feed additives.
