A device for comminuting bulk material grains (K) having a first element, designed as a rotor having a cylindrical circumferential surface with a first surface (31) and a first receiving portion (41), and a second element designed as a shear strip (51) having a second surface (61) and a second receiving portion (71), and a supply unit. The first and the second surfaces (31, 61) lie parallel to and face one another. The first and second elements are relatively movable between first and second positions (P1, P2) in a plane of the first and the second surfaces (31, 61). In the first position (P1), the first and second receiving portion (41, 71) communicate with one another, via a passage (9) forming a receptacle, in which the bulk material grain (K) can be positioned, and, upon moving to the second position (P2), a cross section of the passage (9) is narrowed.

A grinding roll wheel includes an annular body having a front surface, a rear surface, a circumferential surface, and a central cavity. Tungsten carbide is layered or otherwise attached onto a circumferential surface. The tungsten carbide can be applied to the circumferential surface with a MIG weld, a weave weld, or a stringer bead. The grinding roll wheel of the present disclosure may be implemented into a roller mill for comminuting feed material. Grain, ore, gravel, plastic, and the like may be used as the feed material. If grain is used, flour may be produced by comminuting the grain.

An apparatus is configured to apply a treatment agent to an agricultural byproduct. The apparatus includes a fragmenting chamber where the agricultural byproduct is fragmented into particles. An initial amount of a treatment agent is applied to the byproduct in the fragmenting chamber. Particles of a desired size flow through a screen from the fragmenting chamber to a recovery zone. A second amount of the treatment agent is applied to the particles in the recovery zone. A regulator regulates the amount of the treatment agent applied to the particles in the fragmenting chamber and the amount of treatment agent applied in the in the recovery zone. The regulation may be based on one or more feedback mechanisms.

A pulverizing assembly for a mixer having a drive pin may include a primary rotation about a central axis following a circular path and a secondary rotation about a drive pin axis. The pulverizing assembly may include a mounting hub configured for operable coupling to the drive pin and an auxiliary coupling operably couple to the mounting hub to follow the circular path about the central axis and rotate relative to the mounting hub thereby being isolated from rotation about the drive pin axis. The pulverizing assembly may also include a framework extending from the auxiliary coupling and including a laterally extending axle, extending generally orthogonal to the central and drive pin axes. A grinding wheel may be operably arranged on the axle and configured to pulverize material against a surface as the axle moves and the grinding wheel rolls.
