An impact mill (10) has an inlet (12) for material to enter the mill, an impact mechanism (16, 50) arranged to rotate about a rotation axis and being operable to pulverise the material after entering through the inlet, and an outlet (154) for discharge of pulverised material. Blockage sensors (Bj), vibration sensors V, torque sensors Tn, temperature sensors and proximity sensors may be selectively incorporated into the mill.

A impact crusher with dual rotors, an upper rotor (30) and a hammer for the impact crusher are disclosed herein. The upper rotor (30) of the impact crusher comprises two discs on top of each other. The upper rotor (30) comprises a plurality of hammers (40) pointing down, to the outer perimeter of the lower rotor (20) discharging the material to be crushed at high speed. Each hammer (40) has a support shaft (41) that extends vertically between the first disc (31) and the second disc (32). The distance between the first disc (31) and the second disc (32) provides torsional structure to the connection between the hammer and the upper rotor (30).

A hybrid twin process uses an independent mechanical destructive process and an illumination process to change of state of weed seeds to having reduced germination viability by illuminating a seed with at least one of 2 J/cm.sup.2 cumulative illumination energy, and 0.2 W/cm.sup.2 irradiance, but no more than 7 W/cm.sup.2 average irradiance, of at least one of an Indigo Region Illumination Distribution (IRID), and infrared radiation that is substantially Medium Wavelength Infrared (MWIR) radiation, preferably 2-8 microns. The process can be incorporated into a harvester combine to convert a tailings flow prior to discharge on an agricultural field. For the mechanical destructive process, high required applied energy, noise, wear, and difficulty treating impact-resistant seeds are avoided by modifying a driven load flow via increased capability of exposure to illumination and underdriving the mechanical destructive process. This can include randomization, rarefaction and enhanced circulation.

Disclosed is a nano pulverizing device for processing reconstituted rice flour which includes a bottom plate, support legs are fixedly connected to corners of a lower surface of the bottom plate, a housing is arranged on an upper surface of the bottom plate, and a rotating motor is arranged on the lower surface of the bottom plate. The rotating motor penetrates through the lower surface of the bottom plate and extends to the upper surface of the bottom plate, and a crushing device is rotationally connected to one end, extending to the upper surface of the bottom plate, of the rotating motor. A support frame is fixedly connected to an inner wall of the housing, a support plate is fixedly connected to a lower surface of the support frame, and a flexible plate is fixedly connected to a lower surface of the support plate.
