A bead mill and an associated bead-mill-based machine for testing mechanical fragility of red blood cells, employing a cartridge configured to contain a sample while cells get stressed via bead oscillation and, in the case of the fragility testing machine, also while lysis levels get detected, for presentation of fragility information.

The present invention provides an apparatus for the production of Graphene and similar atomic scale laminar materials by the delamination of a bulk laminar material, such as graphite. This apparatus provides prolonged head life and avoids catastrophic head wear in an isolated region. Overall product quality over time is better maintained. Also, the benefit of a self-unblocking delamination apparatus can be achieved whilst maintaining high product quality and consistency. Relatively small variation in gap size being sufficient to avoid blockage, such as occurs by the aggregation of large particles or groups of particles in the high shear gap used for delamination.

A device and method for counter collision treatment. The device includes: first and second nozzles 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 nozzles 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 nozzles 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 nozzles 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 method is disclosed for separating plastic and cellulose from post-consumer absorbent sanitary products. The method includes sterilizing successive batches of post-consumer absorbent sanitary products in at least one rotary autoclave. The method further includes shredding the sterilized absorbent sanitary products and obtaining sterilized and shredded material containing plastic and cellulose. The method further includes 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 powder pulverization device is provided. The device includes a hermetically sealed pulverization container, a powder introduction mechanism having an introduction inlet opened inwardly to the pulverization container, and introducing powder to be pulverized to the introduction inlet, a powder pulverization mechanism disposed at a portion below the introduction inlet in the pulverization container, and a classification device disposed at a portion above the introduction inlet in the pulverization container for screening pulverized powder and leading the screened powder out from the pulverization container. An inner wall of the pulverization container is covered with a porous lining material and each hole of the lining material communicates with an air supply via a gap between the inner wall and the lining material.

A method of preparation of titanium and titanium alloy powder for 3D printing is based on a fluidized bed jet milling technique. Hydride-dehydrate titanium powder and titanium alloy powder are used as main raw material powder, jet milling and shaping are carried out in shielding atmosphere of nitrogen or argon, and finally high-performance titanium and titanium alloy powder meeting the requirements of 3D printing process is obtained. The titanium and titanium alloy powder prepared using this method has a narrow particle size distribution, approximately spherical shape, and controllable oxygen content.

A system and method for dry ablation beneficiation of ore. The system comprises a nozzle to emit an air stream, and a feeder to provide ore particles for entraining in the air stream and colliding. The ore comprises gangue grains bound together with a cementing material. The cementing material comprises a desired material. The collisions are controlled to help preferentially break the cementing material over breaking the bonds holding a gangue grain together. The system also comprises a classifier to separate broken cementing material from the remaining material (which includes gangue grains) based on size. The method comprises entraining the ore particles in an air stream and colliding to preferentially break the cementing material. The ore particles may be collided with each other or a surface. The broken cementing materials are then separated from the remaining materials (which includes gangue grains). The enriched ore is the separated cementing material.
