REQUIRED POWER DETERMINATION FOR THE DRIVE VERTICAL FEEDSHREDDER-MIXER

Abstract

The criteria for assessing the work quality of machines and equipment for preparing feed are operational and technological indicators - the quality of the technological process, work productivity and energy indicators. Grinding is one of the most important technological processes in feed preparation. Preparing feed using modern equipment is accompanied by significant energy consumption. At present, the issues of feed grinding mechanization have not yet been sufficiently resolved.

For grinding roughage of any moisture content, as well as grinding other feed components and mixing them, machines with a multiplane grinding apparatus are used. In a chopper with a multiplane grinding apparatus, feed moves towards the unloading chamber, making circular movements along the inner surface of the working chamber. During movement, they enter the working zone of the cutting elements blade, the design and kinematic parameters of which influence the force applied to grind the feed components entering the working chamber and, as a result, are an influencing factor that changes the power indicators of the installation.

The article presents the results of theoretical studies to determine the required power for the multifunctional shredder-mixer drive of feed, taking into account its design features, physical and mechanical properties of feed and possible fluctuations in feed supply to the working chamber.
