A system for harvesting insects from a habitat. The system configured to separate waste, live insects, and dead insects in a manner that the live insects may undergo a first processing procedure and the dead insects may undergo a second processing procedures. For example, the first processing procedure may include processing the insects for human consumption and the second processing procedure may include processing the dead insects for minerals or materials.

A hopper assembly for accepting placer deposit and water for use with a highbanker includes a hopper and a cover. The hopper includes an intake surface for accepting the placer deposit, a hopper periphery portion extending along a periphery of the hopper, a water intake, and a window configured to allow the placer deposit and water to exit from the hopper. The water intake accepts water and is located within the hopper periphery portion. The cover includes a cover surface and a plurality of cover openings. The cover surface fits over the hopper periphery portion. The cover openings are formed on the cover surface. The cover surface and the hopper periphery portion define, at least in part, a hollow within which water from the water intake flows. The cover openings allow for water to exit the hollow and contact the placer deposit on the intake surface.

A screening apparatus comprising a body, a drive system for imparting vibrations to the body, and screen media that is coupled to the body by a resilient coupling mechanism that allows oscillatory movement of the screen media with respect to the body. In response to vibration of the body, the resilient coupling mechanism causes the screen media to oscillate in a manner that is amplified with respect to the vibration of the body. The amplification may depend on the frequency of the vibrations of the body and/or on the mass of any material gathered on the screen media.

A system for post-print processing of 3D printed parts includes an automated breakout system for separating 3D printed parts from printing media in a tray and a vibratory media cleaning system for removing printing media from the 3D printed parts. The automated breakout system includes a tray input mechanism, a bed including a first end disposed adjacent the tray input mechanism, the bed including one or more passageways configured to pass printing media through the bed, a vibration generator coupled to the bed and configured to vibrate the bed, and a part terminator disposed adjacent a second end of the bed. The vibratory media cleaning system include a vibratory bin, a vibration generator coupled to the vibratory bin and configured to vibrate the vibratory bin, an automated parts loader configured to introduce 3D printed parts to be cleaned into the bin, and an automated parts removal mechanism.

An assembly and method for gravitationally separating gold from particles, and specifically for separating small components of gold, less than 1 millimeter from small particles. A series of sieves having graduated mesh sizes, and arranged in a sequential, stacked configuration sieves the aggregate of large particles and larger components of gold. The remaining small particles and smaller components of gold fall into a container. A pressurized column of fluid is forced into the container. The fluid has sufficient flow velocity to suspend the lighter small particles, but insufficient flow velocity to support the denser, high specific gravity gold. Gold has a large specific gravity relative to the fluid and particles. Gravity causes the gold to falls into a transparent collection conduit. Manipulation of valves enables gold to redirect to a collection bin. Fluid flow is shut, enabling small particles to be flushed out through gravitational forces and excess fluid momentum.

An apparatus for the comminution of a botanical feedstock includes a vessel, a screen positioned in the vessel above a first feedstock outlet and spaced from the top of the vessel, and a blade rotatably mounted above and generally parallel to the screen. The blade has a leading side, a trailing side, and a radial blade length. At least a portion of the leading side has a cutting edge and at least a portion of the trailing side has a downwardly extending trailing portion. The downwardly extending trailing portion has a lower edge having a plurality of discontinuities along a radial length of the trailing portion. The cutting edge is spaced from the upper surface of the screen by a first distance and a lowermost portion of the lower edge is spaced from the upper surface of the screen by a second distance.

A slag crusher includes a screen provided so as to intersect a falling direction of a slag and having openings; at least two spreaders disposed opposite from one another on the screen; and a spreader moving unit configured to support the spreaders and move the spreaders in a direction vertical to the opposing faces of the spreaders. Each spreader includes projections and a lower projection so as to face the other spreader. In a state in which the lower projection is closest to the other spreader, the lower projection does not come into surface contact with the opposed lower projection, and a distance between the opposing lower projections is smaller than an opening dimension of the openings of the screen across a width direction of the spreaders.
