A method for separating plastic and cellulose from post-consumer absorbent sanitary products, comprising: sterilizing successive batches of post-consumer absorbent sanitary products in at least one rotary autoclave, shredding the sterilized absorbent sanitary products and obtaining sterilized and shredded material containing plastic and cellulose, drying the sterilized and shredded material containing plastic and cellulose, and separating cellulose from plastic from said sterilized, shredded and dried material in at least one centrifugal separator.

A water jet splitting chamber for waste tires has a chamber body, a water jet module, and an actuator. The chamber body has a retaining wall located in the chamber body to divide the chamber body into a splitting space and an actuator space. The water jet module is mounted in the splitting space, and has a slide seat mounted on the chamber body and at least one water jet seat mounted on the slide seat and being capable of linearly moving along a mounting direction of the slide seat. The actuator is mounted in the actuator space, and has a motor and multiple linking rods. The multiple linking rods are driven by the motor and extend into the splitting space, extending directions of the multiple linking rods are along the mounting direction of the slide seat, and the water jet heads face toward the multiple linking rods.

A device and method for counter collision treatment. The device includes: first and second nozzle means oppositely disposed so as to inject jets of a highly pressurized fluid into a body protective ring; the injection directions of the first and second nozzle means are determined so as to intersect with an angle at one point located in front of the nozzle orifices thereof. Further, the jets from the first and second nozzle means are caused to collide with each other to thereby effect homogenization of the fluid by impact-fragmentation. Yet further, one of the first and second nozzle means is provided with a turning mechanism for enabling the nozzle to turn around the fixed injection direction as the axis of the turn while keeping the injection direction unchanged.

A vortex mill and a milling method for comminuting of a raw particulate material is described. The vortex mill comprises an outer preferably cylindrical casing fitted with an inlet port for supplying a compressed working fluid into the easing. The vortex mill further comprises a milling chamber, which is situated in the casing. The milling chamber is configured for comminuting the particulate solids therein. The milling chamber is delimited by a side wall, by a lower disc and by an opposite upper disc.

A central opening is provided in the upper disc and at least one nozzle is arranged in the side wall of the milling chamber such that a compressed working fluid could be supplied from the outer casing trough the at least one nozzle tangentially into the milling chamber.

The vortex mill further comprises a discharge collector, which is in fluid communication with the milling chamber via the central opening in the upper disc wall.

A feeding tube is provided which is situated co-axially with the milling chamber and is in fluid communication therewith so as to supply the raw particulate material into the milling chamber.

The vortex mill further comprises at least one comminuting control component enabling comminuting the raw material such that material with customizable parameters of particle size distribution is produced.

A method to focus forward momentum of a material increase the velocity of a specific material or a number of specific materials, said method comprising the steps of: introducing a slurry of material into a high velocity accelerator, where said high velocity accelerator is adapted to impart an increase in the velocity of the materials introduced therein; expanding the volume of the slurry introduced into the high velocity accelerator without diminishing the velocity of the material; entraining said expanded slurry through injection of a liquid at high velocity towards an outlet port located in the high velocity accelerator; and focusing the entrained slurry onto a pre-determined point located proximate the outlet port of the high velocity accelerator.

A high velocity accelerator comprising: an internal chamber; a material inlet port; a material outlet port; a back wall surrounding the inlet port; an internal wall having a first end connected to the back wall and a second opposite end tapering to the outlet port, the first end being located proximate the inlet port and the second end being located proximate the outlet port; a plurality of injection ports positioned along the periphery of the internal wall proximate the first end; wherein said inlet port having a diameter smaller than the diameter of the internal chamber, and the injection ports are adapted to inject at a high rate of displacement a fluid which, in operation, will create a vortex inside the chamber thereby entraining a material towards the outlet port. Uses and methods using such are also disclosed.

A method of pulverizing solid material for the purpose of extracting metals which may otherwise not be recoverable and/or cost prohibitive using conventional means and processes, said method comprising the steps of: using a gas to create a fluidized flow of previously crushed solid material; transporting the fluidized flow of solid material to an apparatus which induces a high velocity flow stream in a constricted low-pressure stream; causing a rapid acceleration on a rotational angle of the crushed solid material resulting in increased interparticle collisions and collection of solid particles; and ejecting the material at a high rate of speed from the apparatus to a focal point where the material is pulverized.
