Theoretical research of the parameters of the biters that distribute feed to the grinding rotor

Abstract

Justifying the diameter of the distribution biters and the number of rotations of the device that grinds the pressed feed to the level required by zootechnical standards is the primary goal of the study. The press feed distribution biters’ plan and its working principle are presented. It is necessary to scientifically justify the number of shovels of the proposed distribution biters and the width of the slits between them. During crushing the feed collected by the press, it should ensure the transfer of specified amounts without being stuck in the rotor of the device. The output of the pressed feed grinding device should be 500-600 kg/h in the main time, 400 kg/h during its use, and the length of the crushed feed should be for cattle. 30-50 mm, for sheep it should be 30-40 mm. Based on this, we accept the productivity of 600 kg/hour, the cutting length of 30 mm. In this instance, it was found that in order to maintain the device’s stated productivity of 500–600 kg/h, the biter revolutions should be between 250 and 300 r/min.
