SYSTEM AND METHOD FOR DRY ABLATION BENEFICATION OF ORE
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.
Jet mill
In an axial jet mill, an internal structure having a cylindrical outer surface is positioned within a housing to establish a raceway for the circulating movement of gas and solid material while maintaining the gas and solid material in close proximity to the outlets of gas nozzles distributed around the perimeter of the raceway. Solid material enters the jet mill though a bottom wall of the housing and passes into the raceway though gaps between the bottom of the internal structure and a bottom wall of the housing. Particles and gas exit the jet mill though a central outlet in the housing located above the internal structure.
METHOD OF GRINDING POLYARYLETHERKETONES
An improved method of grinding polyaryletherketones, providing very good yields and the production of powders of polyaryletherketones with an average diameter below 100 μm having a narrow size distribution with few fine particles (Dv10>15 μm). Method of grinding polyaryletherketones of apparent density below 0.9 carried out in a temperature range between 0° C. and the glass transition temperature of the polymer measured by DSC, in order to obtain powders having a particle size distribution (diameters by volume) of d10>15 μm, 50<d50<70 μm, 120<d90<180 μm.

Eggshell powder compositions and methods of producing eggshell powder compositions
A process for manufacturing eggshell powder for use in the production of bio-based products is provided. The process involves exposing a quantity of eggshell to high air speed at room temperatures to pulverize the eggshell and separate the eggshell component from the inner membrane component. Thus, the process avoids the use of high temperatures and other harsh chemical treatments to remove the inner membrane from the eggshell thereby resulting in an eggshell material that retains the original lipid-protein structure of the native eggshell from which the powder derives. Accordingly, an eggshell powder composition is provided that is substantially free of inner membrane material and possesses a lipid-protein structure substantially similar to that of the eggshell from which the powder is derived. A polymer composite composition comprising an eggshell component and a polymer component is also provided.

Method of using bead milling in erythrocyte fragility testing
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.
