INSTALLATION OF FRACTIONAL CRUSHING AND PRODUCTION OF MIXTURES OF CONCENTRATED FEEDS Russian patent published in 2019 - IPC A23N17/00 

FIELD: agriculture.

SUBSTANCE: invention relates to agriculture, in particular to devices for grinding and simultaneously mixing the ingredients of feed grains with mineral, vitamin and medicinal premixes, and can be used in the preparation of compound feed. Installation includes dosing, grinding and mixing units, transportation and separation, a crusher-mixer with a vertically mounted rotor and a cylindrical perforated sieve, as well as a container for collecting foreign objects. Crusher-mixer equipped with a discharge manifold. Spouts of the discharge manifold are mounted on the cylindrical part of the housing of the crusher-mixer and are embedded in the sluice gates. Gateways are located diametrically opposite on the housing of the crusher-mixer and communicated with the barred space of the crusher and the feed line. Cross-sectional area of the feed pipe is equal to the sum of the areas of the sluice gates. Container for collecting foreign objects is located below the pallet and is communicated with a barred space around the entire circumference of the perimeter.

EFFECT: use of the invention will allow to obtain a feed mixture of grinding a given fraction, to reduce the size of the installation, as well as to reduce the energy intensity and intensity of the installation.
