A regeneration treatment method of waste shell-mold and a system thereof are provided. The regeneration treatment method has a raw smashing step, a smashed-particle sieving step smashed-particle, a first magnetic separation step, a grinding step, a second magnetic separation step, a dry pneumatic flotation step, and a vibration sieving step in sequence to obtain a regenerated shell-mold sand. The refined shell-mold sand is obtained from the smashed-particle sieving step. Silica binders of the refined shell-mold sand is effectively removed by the grinding step. Furthermore, particle sizes of the regenerated shell-mold sand fall in a suitable range in the grinding step. Magnetic metals mixed in the waste shell-mold are effectively removed by the first and second magnetic separation steps. Non-magnetic impurity are further removed by the dry pneumatic flotation step. Therefore, the regenerated shell-mold sand are suitable to substitute original shell-mold sand.

The present invention discloses a same-cavity integrated vertical high-speed multistage superfine pulverizing device and method for walnut shells. The same-cavity integrated vertical high-speed multistage superfine pulverizing device for walnut shells includes a double-channel sliding type feeding device and a same-cavity integrated vertical pulverizing device. The same-cavity integrated vertical pulverizing device includes a material lifting disc and a same-cavity integrated vertical pulverizing barrel. A first-stage coarse crushing region, a second-stage fine crushing region, a third-stage pneumatic impact micro pulverizing region and a fourth-stage airflow mill superfine pulverizing region are disposed in the same-cavity integrated vertical pulverizing barrel. Walnut shells falling through the double-channel sliding type feeding device are uniformly lifted by the material lifting disc to a wedge-shaped gap of the first-stage coarse crushing region to be coarsely crushed, and coarsely crushed materials are finely crushed by the second-stage fine crushing region through a two-stage wedge-shaped direct-through gradually reducing gap. The third-stage pneumatic impact micro pulverizing region performs high-speed collision on finely crushed walnut shell particles, and walnut shell fine particles are carried by a high-speed airflow and are collided and violently rubbed to be pulverized. The microparticle grading is realized by the fourth-stage airflow mill superfine pulverizing region by using arc-shaped blades, and microparticles conforming to a particle size condition are attracted out through negative pressure attraction.

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.

The present invention relates to a method of cleaning solids to be free of, or separating solids from, viscous materials and in some cases other solids such as, but not limited to resins and other coatings, foreign debris, clays, silts, contaminated water or chemicals and in other cases separating some liquids form some other liquids. Also disclosed are systems to accomplish such.

The present invention relates to a method for preparing a non-acid-treated eco friendly cellulose nanocrystal and the cellulose nanocrystals prepared by the same. The methods for preparing the non-acid-treated cellulose nanocrystal and extracting the cellulose nanocrystal from cellulosic materials of the present invention are eco-friendly methods, compared with the conventional preparation method for cellulose nanocrystal based on acid-hydrolysis; are efficient due to the total energy saving process; are easy to utilize side products; and are characterized by high yield to produce the target cellulose nanocrystal. The nanocrystal prepared according to the present invention exhibits equivalent or higher aspect ratio, yield and crystallinity than the cellulose nanocrystal prepared through acid hydrolysis, and has remarkably excellent thermal stability, so that it can be effectively used for the production of membranes, electrical and electronic parts, substrates, heat insulating materials, and reinforcing materials required for durability against heat.
