A device for granulating powders by cryogenic atomisation, characterised in that it comprises: a device for mixing powders by cryogenic fluid, comprising at least one chamber for mixing powders, comprising a cryogenic fluid; and a device for atomising a suspension of powders mixed by the device for mixing powders in order to allow a granulation of the powders, comprising a way of fractionating the suspension of powders making it possible to adjust the size of the droplets of powders to be atomised, and a method for adjusting the moisture of the mixed powders and/or the moisture of the atomisation atmosphere.

A waste management system for plastic or other material floating on the surface and in the subsurface of a body of water. A shredding device will reduce the size of the particles of waste. Ocean water is removed by a drying device. The dried waste material is frozen to a temperature at or below minus fifty degrees Fahrenheit, using liquid nitrogen or other suitable means. The frozen waste material is then pulverized and ground into a powder. The powder may then be sprayed into a gas-filled chamber and heated. Temperature, pressure and humidity are maintained within the chamber for more than one minute. Microwave or other radiation and catalysts may be used to enhance the process of extraction. The processed material is then removed from the chamber. Carbon may be recycled or used as fuel by the ship. Water may be used by the ship or returned to the ocean.

A system for eliminating unexploded ordnance from a mixture. The system includes a separation plant, including a crusher, a magnetic separation station, and a screen plant. The crusher reduces the size of pieces in the mixture, the magnetic separator separates pieces containing a significant amount of ferrous metal, and the screen separates small pieces from larger pieces. The fine output of the screen is composed of pieces that are sufficiently small to pose little hazard; they may be further subjected to heat treatment. Large pieces containing ferrous metal, or large pieces containing nonferrous metal, may be explosive and are transported, using an unmanned machine, to an inspection plant where they are sorted and where any unexploded ordnance is identified and disposed of. The separation plant is sufficiently distant from the inspection plant that an explosion at the separation plant does not pose a hazard to personnel at the inspection plant.

A plant (1) and method for recovering plastic materials of post-consumption materials, such as vehicle bumpers and tanks, in the plant, downstream of the volumetric reduction grinder (2), there is provided an intermediate grinder (6) and the washing vat (9) and the centrifuge (12) additionally being arranged upstream of the windmill/granulator (14), while in the method, an intermediate grinding step is arranged upstream of the grinding/granulation step and a subsequent washing step and separation in the vat of the parts of foreign materials through the difference of specific weight, including ferrous, non-ferrous materials and alloys thereof, of the material made of intermediate size, before the grinding/granulation step through windmill/granulator, wherein the washing and centrifugation water is subjected to a continuous purification cycle. In order to increase the productivity of the plant and reducing the maintenance times, the conveying elements for transporting the material are provided mobile, mounted on swivel wheels.

A portable feed mill machine having a plurality of spaced-apart feed mills positioned on a wheeled frame such as a trailer. Any one of the feed mills may be taken out of operation for repair without the other feed mills being taken out of operation. The machine may have a plurality of mechanized devices rather than the feed mills.
