Theoretical aspects of root crop grinder development

Abstract

The article presents results of theoretical studies on development and calculation of a root crop grinder. A mathematical description of the process of movement of cutting elements and feed particles in a cylinder-type root crop grinder with a vertical location of the cylinder is presented. Dependencies between design and operating parameters of the developed root crop grinder were obtained. The research results can be used in development of root crop grinders for preparation of root crops for cattle, pig and poultry feeding.

The study of metal oxidation process when metal is exposed to waste products of farm animals

“…Animal waste products contain corrosive substances in their composition, the content of which is determined by metabolism in the animal body [8]. Thus, for example, the waste products of cattle may contain 500...2800 mg/l of sulfate ions, pigs -190...210 mg/l.…”

Study of the efficiency of the transport support of forage harvesters when harvesting corn for silage in the conditions forest-steppe zone

“…Most often, the increase in the cost of the forage base is due to the inclusion of additional costs of the harvesting process: transportation and storage. Large volumes and short agrotechnical deadlines for performing forage harvesting work on farms require the involvement of a large amount of equipment and labour resources; the share of the harvesting and transport process during this period accounts for more than 75% of labour and funds costs [21][22][23][24][25].…”
