Abstract:
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/cm2 cumulative illumination energy, and 0.2 W/cm2 irradiance, but no more than 7 W/cm2 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.
Abstract:
The essence of the invention is that it involves the feed of a material to be ground and the acceleration of said material. During acceleration, jets are formed from a mixture of material to be ground and air and said mixture is fed to an annular grinding chamber. Simultaneously, a stream of air is fed into the grinding chamber in a direction contrary to that of the mixture jets. Local cyclic variations in the pressure and rate of the air stream and/or in the pressure and rate of the mixture jets are formed along the perimeter of the grinding chamber. The finished product is removed. The material grinding device comprises a housing with a unit for the feed of the material to be ground and a unit for the removal of the finished product. An annular grinding chamber is accommodated in the housing. Two rotating rotors with the blades fastened thereto are coaxially arranged in the housing. The blades for accelerating the material to be ground and feeding said material into the grinding Chamber and/or the blades for feeding air into the grinding chamber are arranged at varying intervals.
Abstract:
A crushing and mill device includes an outer rotary disk (1) and an inner rotary disk (2) put in said outer rotary disk, wherein, the outer and inner rotary disks communicate the inlet (3) of the feed material, some through holes (20) communicating the outer and inner disk are provided on the sidewall of the inner disk, some carrier plates (4) for carrying the feed material are provided on the places that correspond to the through holes (20) on the disks. The rotations of the outer and inner disks are driven by motors, and the rotations direction of the inner and outer disks are opposite. The sidewall of outer disk has an outlet (10) of the feed material. The feed material enters the inner and outer disks from the inlet, and the feed material is shot off oppositely by the rotations of the outer and inner disk. The feed material passes the through holes of the inner disk and impacts with each other to be broken and milled. The particulates formed by milling are shot off from the outlet on the sidewall of the outer disk. The device can lower energy consumption and raise output.
Abstract:
An apparatus and method for separating joined components, purifying liquid, promoting interaction between two or more components and improving combustion. The apparatus has a housing, a rotor inside of the housing, a plurality of protrusions extending from the rotor, a shaft coupled with the rotor and a prime mover for rotating the shaft. Fluid within the housing cavitates as the rotor rotates and the protrusions move through the fluid. Cavitation causes joined components within the fluid to separate, kills undesirable organisms within the fluid, promotes interaction of components within the fluid and improves combustion of a liquid fuel. The fluid and components may also be subjected to abrasion and centrifugal and impact forces for separating the components, purifying the fluid, promoting interaction of the components and improving combustion.
Abstract:
The invention relates to a method for the disintegration and tribochemical activation of especially inorganic materials having a crystalline structure, wherein the starting materials are comminuted (disintegrated) to a particle size of less than 1 μm by the effect of impacting pressure fronts at a pulse duration of less that 10 μs and a sequence frequency of more than 8 kHz. A conglomerate of activated mixed crystals is then obtained. Said conglomerate has an increased aptitude for the formation of modified crystals when water is added. The duration of the effect of the impacting pressure fronts continues until the crystal lattice structure of the particles (30) is destroyed. A device for the disintegration and tribochemical activation of said materials is based on rotating disks whereon moulded bodies with aerodynamical profiles are arranged, said moulded bodies being continuously displaced in a transonic speed range and impacting pressure fronts being produced on the outflow surfaces thereof.
Abstract:
A method for breaking down used materials or items, particularly wooden or motor-vehicle items, into reusable components with the use of fractionating tools, with which the accelerated parts of used material interact. The breakdown is effected selectively through impacts, deformation tension, bending stress, friction and/or shearing, with the shape and arrangement of the fractionating tools being set and/or matched to the structure and size of the used feed materials and/or the obtained recycled material.

A method and a cleaning device for the mechanical cleaning of a powder, in particular of primary aluminum oxide, direct the powder against a surface in order to strip particulate impurities adhering to the surface of the powder. The aluminum oxide to be cleaned is introduced into a stripping device having a striking mechanism directing the powder with a speed of 20 to 30 m/s several tens of times per second for a time period of 10 .mu.m are separated from the cleaned, powder-form aluminum oxide having a size
Abstract:
A rotary disintegration apparatus comprises a housing with a central material input and a material outlet that is open underneath, an inner rotor fixed to a first shaft and an outer rotor fixed to a second shaft on the same axis that rotates in the opposite direction, and blade rings that follow each other in alternation having blades which are inclined in the direction of rotation, which can be coated with a protective layer, which have front and rear edges of hard wear-resistant material, and which sit on one side on retaining rings and on the other side on assembly rings forming replaceable components of annular assembly ring carriers that are connected to the shafts. The blades are so arranged at a distance from the edges of the assembly and retaining rings of their blade rings that the front edges of the blades of a blade ring and the rear edges of the blades of the following blade ring which rotates in the opposite direction define annular chambers within the disintegration chamber, within which, within the nominal speed range of the rotors, vortex zones of the gas-solids mixture are formed.

A drive and bearing arrangement for two rotor systems of a disintegrator which rotate in opposite directions and are mounted next to each other. Each rotor system has a rotor support member and a drive hub. The rotor support member of each rotor system is rotatably mounted through a rotor bearing directly on a common vibration absorbing and elastically mounted support and supply tube. The other end of each hub is rotatably mounted through a drive bearing on an axially movable shaft stub mounted in a bearing block.
