Gypsum granules to which wasted gypsum boards are crushed are stored in a silo and discharged from the silo smoothly. Wasted gypsum boards are crushed to gypsum granules and are stored in a silo. A plurality of screw conveyors is provided at the bottom of the silo, and the gypsum granules in the silo are discharged toward outside of the silo by the screw conveyors.

Provided is a water absorbent resin that is useful to sanitary materials such as a disposable diaper, a sanitary napkin, and a blood absorbent for medical use each having a higher liquid permeability and a higher water absorbing speed. Further provided is a water absorbent resin powder that is useful to sanitary materials such as a disposable diaper, a sanitary napkin, and a blood absorbent for medical use each having increased in absorbency of a liquid and in heat retaining property. A gel grinding device to be used to produce a water absorbent resin, includes: a screw; a feed opening; an extrusion opening; a porous plate; and a barrel, the barrel including a return preventing member provided on an inner surface thereof, and the return preventing member satisfying at least one of specific parameters.

A hemp flower, bud, and leaf material stripping machine having a housing, a motor and gearbox that drive a pair of rollers inside the housing, an adjustable locking shaft that adjusts and maintains a space and pressure between the rollers, and a series of feed holes of different diameters on a front side of the housing. Each feed hole is constructed to strip flowers, buds, and leaves from a hemp stem as the stem is inserted into a feed hole and is pulled through the feed hole by the rollers. The flowers, buds, and leaves are severed from the stem at an exterior of the front side of the housing, without damage to the flowers, buds, and leaves. The feed hole is constructed with close tolerance so that the stem can pass through the feed hole but the flowers, buds, and leaves cannot. Hemp stems are stripped in seconds. The flowers, buds, and leaves are not crushed, cut, torn, or compressed as they are severed and fall into a container.

An impact reactor for comminuting composite materials having a rotor with impact elements is arranged in a cylindrical casing. An end face of the impact reactor, remote from the rotor, is closed by a cover. A suction opening is assigned to the cover and a classifying device is assigned to the suction opening. Such an impact reactor may be used to process, by way of example, accumulator batteries, mineral wool and raw material.

A method of preparing adipose tissue for transplantation, from lobular fat extracted, for instance, by liposuction, said fat consisting of a fluid component comprising an oily component, a blood component and/or sterile solutions and of a solid component comprising cell fragments, cells and one or more cell macroagglomerates of heterogeneous size, characterized in that it includes at least one step of forming an emulsion of the fluid component in the sterile washing solution by means of active and/or passive stirring means and discharging the emulsion from the outlet through a density gradient.

Precursors, and methods for manufacturing perforated composite parts, an exemplary precursor including structural fibers embedded in a cured matrix material and interposed between two removable plies, where the precursor may also have a sacrificial fiber extending through the removable plies, the matrix material and between the structural fibers.

Detonable devices such as charged air bag inflators are fed to a shred tower at a controlled feed rate via a feed valve. Water spray and/or water baths in the shred tower prevent sparking and begin to solubilize chemicals while the inflators are fed to primary and optional secondary shredders respectively performing course and fine shreds. A sump receives the shredded material which continues solubilize and separate chemicals from metal. A conveyor lifts solids from the sump. Dewatered solids are fed to a receiving box for metal scrap recycling.

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.
