Dry nano-sizing equipment with fluid mobility effect dryly processes viewable fine-grained substances into a nano-sized dimension by high-pressure airflow resulted from a pressure-generating unit, as well as high-speed fluid and high mechanical momentum generated in a pressure cylinder by high-speed rotation of a booster impeller.

Non-limiting embodiments of the present disclosure relate to a method comprising: obtaining asphalt shingle waste (ASW) and performing grinding, screening, and separating steps on the ASW. In some embodiments, granules are removed from the ASW. In some embodiments, the method transforms ASW into ASW powder. In some embodiments, the ASW powder is formed into a plurality of briquettes. In some embodiments, at least one of: the ASW powder, the plurality of briquettes, or any combination thereof is fed into a mixing process that results in an ASW powder filled coating.

Method and apparatus for fracturing particulates during an air mill process. In some embodiments, a disc assembly is rotated within a housing about a central axis. The disc assembly includes a horizontally extending annular ring with opposing innermost and outermost edge surfaces. A retention flange extends adjacent the outermost edge surface of the annular ring. Spaced apart impellers project from an upper surface of the annular ring for movement in a direction of rotation of the annular ring to form an inner zone of lower pressure surrounded by an outer zone of higher pressure. During air mill processing, an inlet stream of particulates is introduced to the inner zone to induce collisions among previously introduced particulates into the inner zone. Reduced-sized fractured particulates are removed from the inner zone using a negative pressure supplied via a vacuum line.

The invention relates to a jet mill comprising a milling chamber with a longitudinal axis, an inlet at one end of the axis and an outlet at the opposite end of the axis, the milling chamber comprising a multitude of pins arranged in the free flow cross-section of the milling chamber, wherein the pins are arranged in at least two planes perpendicular to the longitudinal axis, the planes being distant to each other in the longitudinal direction, and the pins of one plane being laterally offset to the pins of the subsequent plane, wherein the milling chamber is divided into alternate pin segments and acceleration segments, the pin segments each having at least two planes of pins, and the acceleration segments having no pins.

A pill pulverizing kit is a system that contains, processes, and subsequently dispenses pills and similar hard medications. The system includes a tubular receptacle, a crushed-pill repository, and a plurality of pill-processing devices. The tubular receptacle is a container utilized as the primary housing for pills both before and after pulverizing, as well as the housing for the components involved in crushing and consumption. The crushed-pill repository is a curved indent that collects and contains crushed pill material until the user is prepared to consume or serve the pill powder. The plurality of pill-processing devices relates to a series of removable additions to the tubular receptacle that provide various functions, including pill pulverization and content dispensing and consumption. The plurality of pill-processing devices includes a lid for consumption, as well as an impact driving mechanism that generates power and force for pulverizing pills.
