Abstract

In Russia 2017 was declared the Year of ecology. Enormous amounts of wastes resulted from scouring of agricultural crops (husks of sunflower, buckwheat, panicum etc.) impair environmental situation. Nevertheless, such wastes are widely applied in various industries. In order to use the wastes after processing of agricultural products it is necessary to grind them and to mix with various components in certain ratios. Hammer mill grinders are the most widely applied machines. However, their design and workflow are characterized by certain disadvantages leading to quality impairment of final products and significant energy consumption. Thus, we developed new designs of hammer mill grinder and hammer which allow to reduce grinding energy consumption and to increase yield. This article is devoted to theoretical study of optimum angular speed of rotor shaft with the hammers of the proposed grinder design.
