GRAIN CRUSHER WITH INCREASED SEPARATION SURFACE Russian patent published in 2018 - IPC B02C13/00 

FIELD: desintegrators and crushing devices.

SUBSTANCE: invention relates to devices for grinding loose materials and can be used in agriculture and other industries. Grain crusher includes a housing with loading and unloading windows, an electric motor, a rotor mounted on the motor shaft, hammers hinged on the rotor, and sieves. Hammers are made in the form of plates longitudinally bent at an angle of 80…120° directed with the outer sides of the angle along the rotor's motion. In this case, the end sieves are located perpendicular to the axis of rotation of the rotor on both sides of it, and the peripheral sieve – outside the rotor around its axis of rotation.

EFFECT: increased performance, reduced energy consumption and increased life of hammers is ensured.
