Determination of the Regression Coefficient when Grinding Grain Feeds with Small-Sized Grinders

Abstract

Grinding of fodder grain is the most commonly used and obligatory method of preparing grain feeds. At the same time, the solid grain shell is broken, the nutrients become more accessible to digestive juices, the digestibility is accelerated, and the energy of the feed is more fully digested. In conditions of farms, it is reasonable to prepare grain feeds at the farm using their own food resources. Small-sized hammer feed grinders are widely used for this purpose. These machines have a low metal-energy intensity, simple structure, and are mobile and very cheap. Using the regression equation, the dependence of the power on the productivity, number of revolutions, and radius of the grinder are determined. The presented calculation method allows selecting the efficient parameters of the grinder providing the process quality with the minimum energy consumption.
