Disk-type rotor is provided with rows of fingers arranged in concentric circles between pins. Blades are mounted on disk-type rotor. Disk-type rotor is equipped with drive made in the form of end electric engine positioned inside vertical chamber and equipped with circular immovable stator. Electric engine rotor is formed by part of disk-type rotor faced to stator and made in the form of flat ring, which is manufactured from magnetic material and provided with current-conductive material. Ratios for selecting optimum sizes of disk-type rotor, stator and rotor of electric engine are recited in Specification. Feed grinder is used for grinding plant feeds at animal farms. EFFECT: convenient operation of grinder in restricted space, simplified construction, reduced weight and sizes, improved quality of ground feed and reduced power consumption. 2 dwg
