A device for increased micronization efficiency of solid materials. The device comprises a housing with two discs, separately driven by motors through axles, such that the discs rotate in opposite directions. Each of discs bears at least two or more wreaths of blades such that two adjacent wreaths that belongs to different discs do rotate, relatively one to another, in opposite directions, forming an area where micronization of material takes place. The wreaths of blades of different discs are faced one against another. All blades of wreaths are identical, in the shape of a “T”, and include three wings; two wings are dimensionally identical and set under the right angle, whereas the third wing is set dimensionally larger than the other wings. Centerline of all three wings meet each other in the center of the blade, on a circle that goes through half of the wreath.

A device and method for comminuting ore and/or slag comprises an ore feeding unit for feeding ore to a pulverizer, wherein the pulverizer includes at least two comminuting elements that form at least one comminuting space for the ore such that, by a relative movement in the form of a rotation of at least one of the comminuting elements, the ore is pulverized. One or more accelerating elements are provided on at least one of the comminuting elements for accelerating and comminuting the ore by the rotation of one of the comminuting elements. An intermediate space is provided between two comminuting elements and/or in at least one of the comminuting elements, through which the pulverized ore, during the rotation, is transported from the center of rotation, and an outlet unit is provided, which is connected to the intermediate space and through which the pulverized ore is discharged.

A device for comminuting input material, especially for fine and ultrafine grinding of input material, includes a rotor revolving around a shaft inside a housing, the rotor having a cylindrical or conical jacket surface. An annular gap is present between the housing and the jacket surface, the gap forming a comminution zone and the input material being introduced axially to it. To increase the economic efficiency of the device, it is provided that a plurality of first pin-shaped comminuting tools for comminuting the input material are disposed over the circumference of the rotor, wherein the tools are aligned with their longitudinal direction perpendicular to the jacket surface in the direction of the housing.

A method of harvesting crop material includes gathering the crop material and separating chaff material, and subjecting the chaff material to fragmentation in a cage mill to destroy unwanted seed material contained therein. Also provided is a mobile agricultural apparatus which travels with a harvesting machine during a harvesting operation to receive chaff material produced during the harvesting operation. At least one cage mill having rotors for fragmentation of the chaff material is included with the mobile apparatus, to destroy unwanted seed material contained therein. Such a cage mill includes at least a casing defining a milling zone, a rotor for performing milling, an inlet for introducing material for reduction into the milling zone, an outlet for removal of material from the milling zone, and an airflow through the milling zone to assist movement of the material through the milling zone from the inlet to the outlet.

A method and apparatus for biological and/or chemical decomposition of waste containing organic matter. The method includes waste pretreatment in which waste is fragmented and homogenised in a pretreatment apparatus (10a, 10b) operating on the principle of a multi-ring double action impact mill. The apparatus has either two rotors (62, 64) or a rotor and stator disposed inside a housing (26), which rotors and/or stator are equipped with blades having impact surfaces, and which form one or more rings (1,2,3, . . . ) coaxial with the rotor. The waste is fed into the housing through the hub of rings formed by the blades, and travels by the effect of a rotor or rotors, to the outer ring of the ring (7) formed by the outermost blades, and further to the discharge opening (25, 27′) at the outer ring.

It is an object of the present invention to provide a particle crushing and sizing apparatus having a sufficiently wide particle crushing and sizing range, capable of being scaled down in size, and having high processing throughput. To achieve the object, a particle crushing and sizing apparatus has, in a casing 1a, a horizontally provided drive shaft 2, a plurality of circular plates 10 fixedly supported with intervals at the drive shaft 2, and stators 5 arranged so as to be opposed to plate faces 10a at lower peripheral edges of the circular plates 10 and each having inclined faces 5b that cause a gap between the plate faces 10a of the circular plates 10 to become narrower toward peripheral edges of the plate faces 10a. The plate faces 10a of the circular plates 10 and the inclined faces 5b of the stators 5 form gap portions A where particles are held, and particle crushing and sizing portions B are formed by the peripheral edges of the circular plates 10 and narrowest gap portions between the peripheral edges of the circular plates 10 and the inclined faces of the stators 5.

A device for comminuting material comprising first and second mating sections. The mating sections when mated form an enclosed interior chamber with the first and second sections capable of movement relative to each other. The first mating section has a first set of a plurality of pins, which extend from a base of the first mating section and into the interior of the chamber. Similarly, the second mating section has a second set of a plurality of pins extending from a base of the second mating section and into the interior of the chamber. The pins from the first mating section interdigitate with the second set of a plurality of pins when the first and second mating sections are mated, wherein movement of the first and second mating sections relative to one another causes comminution of the material when placed in the chamber. The pins have varying cross-sectional shapes including circular, triangular, and hexagonal.
