The present invention provides for biochar coated particles and a method for coating the particles with biochar.

A reactor for forming fully coated particles having a solid core, the reactor comprises a reactor vessel which is configured to receive particles, and a gas phase coating mechanism that is configured to selectively introduce pulses of gas phase materials that form a coating on the particles. The reactor also includes a sieve (16) that is located within the reactor vessel, and a forcing means that is configured to force the particles through the sieve (16) in use. The sieve is configured to deagglomerate any particle aggregates formed in the reactor vessel upon forcing of the particles by the forcing means through the sieve.

A production line of a CA abrasive, including: a belt mold, the belt mold being provided with a cavity; a transmission device, configured to drive the belt mold to run; a slurry coating mechanism, configured to coat a slurry on a surface and into the cavity of the belt mold; a slurry scraping mechanism, configured to scrap the slurry coated on the surface of the belt mold into the cavity; a drying mechanism, configured to dry the belt mold so that the slurry is dried and precipitated into abrasive grains; a separation mechanism, arranged below the drying mechanism and configured to shake down the abrasive grains in the cavity of the belt mold by vibrating; a sweeping mechanism, configured to sweep slurry fragments of the belt mold after separation; and a release agent coating mechanism, configured to spray a release agent to the swept belt mold.

Disclosed herein are methods, systems, and compositions for the liquid-phase deposition of film coatings onto the surface of battery material powders. The battery material powders are introduced into a reaction vessel within which the coating is to be performed. A solvent is added to the reaction vessel to fluidize the battery material powders, thereby yielding a slurry composed of the solvent and powders. A first reagent is then added into the reaction vessel to react with the slurry to produce battery material powders comprising an adsorbed partial layer of the first reagent. A second reagent is added into reaction vessel to react with the battery material powders comprising an adsorbed monolayer of first reagent, thereby yielding coated battery material powders comprising at least one monolayer film.

The present application is directed towards systems and methods for adding components to materials being fluidized in a vibratory mixer by use of atomizers or sprayers. A mechanical system can fluidizes, mix, coat, dry, combine, or segregate materials. The system may comprise a vibratory mixer, mixing vessel containing a first material and a sprayer to introduce a second material. The vibratory mixer may generate a fluidized bed of a first material and the sprayer, coupled to the mixing vessel, may introduce a second material onto the fluidized bed to mix the materials in a uniform and even fashion.

An apparatus for coating or encapsulating articles, having a drum with a perforated wall rotatably assembled in a wrap-around chamber and suitable for containing and stirring a batch of articles to be coated; a dispenser group with one or more nozzles for spraying a coating product; a gas inlet to direct clean drying gas against the perforated wall and a gas outlet to extract from the chamber dirty drying gas. An adjustable closure system is interposed between the drum and the gas outlet of the chamber, defining a passage for the dirty drying gas smaller than the passage by the gas outlet and further displaced or concentrated coinciding with the area of the wall of the drum that is effectively covered by the batch of articles. An automated adjustment of the locking system is envisaged, taking into account the position of the nozzles within the drum.

A method of operating a gas-solid fluidized bed (130) is provided. The method comprises: flowing a pulsating gas flow upwards through a bed of solid particles from a distributor (104) to cause a dynamically structured bubble flow (130; and processing particles using the fluidized bed.

Technologies are described for a method of making an encapsulated reactant having a desired shape or size. The method comprises providing solid reactant particles and an encapsulating material. The encapsulating material is heated above its solidification temperature to form a molten, semi-solid, or liquid encapsulating material. The solid reactant particles are added to the molten, semi-solid, or liquid encapsulating material and mixed to disperse the solid reactant particles in the encapsulating material and form a mixture. The mixture may be extruded or formed into the desired shape or size of the encapsulated reactant, or the mixture may be solidified and extruded, granulated, shredded, ground, or pressed into the desired shape or size.
