An improved process and apparatus for separating organics and inorganics from waste material with a specific object of preparing the separated organic fraction for the production of biogas or other methods for diverting organics from landfills. Waste material, such as municipal solid waste or source-separated organic waste (SSO), is subjected to a first separation treatment that separates organic and inorganic waste components. The apparatus includes a hopper to receive contaminated organic waste from different sources, a vertical separator that separates the inorganics from the organics by creating a vortex effect in a stationary filtration drum by which the solid contaminants (paper, plastic, metals) are blown in a spiral pattern upwards and removed from the top, while the organic fraction is removed from the bottom.

Such apparatus is improved through novel methods to reduce or eliminate blockages and their associated downtime, and to increase the efficiency of the separation process.

An apparatus for treating leather waste includes: a main body having an inlet and an outlet; a sorting unit rotatably installed in the main body and comprising a plurality of treatment parts having processing components to sort leather inserted into the main body through the inlet; and a power unit configured to rotate the sorting unit.

A material reducing machine includes a rotor assembly having a plurality of short cutting tools and a plurality of long cutting tools. The short cutting tools are arranged in rows which extend across the length of the rotor assembly, which rows are spaced around the periphery of the rotor assembly. Each of the short cutting tools has a cutting bit with a leading edge that is spaced outwardly from the periphery of the rotor assembly by a short cutter distance. The long cutting tools are also arranged in rows which extend across the length of the rotor assembly, which rows are spaced around the periphery of the rotor assembly. Each of the long cutting tools has a cutting bit with a leading edge that is spaced outwardly from the periphery of the rotor assembly by a long cutter distance that is greater than the short cutter distance of each of the short cutting tools. A breaker assembly includes a plurality of shear blocks, each of which is spaced so as to be aligned with a short cutting tool.

The present invention discloses a centrifugal intelligent construction device for excavating concrete structure: a push-type excavation equipment, excavating rocks and soil, and collecting crushed stones, sand, soil, and water; a centrifugal screening equipment, performing centrifugal screening and classification collection on the collected crushed stones, sand, soil, and water; the intelligent batching equipment, which matches the classified crushed stones, sand, soil, and water according to their quality and fineness, adding cementitious materials, auxiliary materials, additives, and activators, and mixing them to obtain a mixed wet material; a centrifugal printing equipment, pumping and extruding the mixed wet materials, and using a centrifugal rotating outer cylinder to print and compact them into dense shape; an intelligent reinforcement equipment, integrating reinforcements between the layers of printed concrete strips by using the wall mounted laying, positioning and inserting reinforcements inside the printed concrete strips during the centrifugal printing process to form an integrated reinforced concrete structure. The device can achieve the additive and intelligent construction of closed concrete structures in underground, underwater, and extreme construction environments, solving the technical dilemma of insufficient engineering application scope of open additive manufacturing technology.

A mulcher includes a hopper, having an inlet end and an outlet end, the hopper configured to receive vegetative debris via the inlet end; a chipper unit having an outer casing and an inlet passing therethrough, the inlet connected to the hopper outlet end to in use receive the vegetative debris within the casing, the chipper unit further comprising a cutting means located within the casing and configured to chip and/or mulch vegetative debris within the chipper unit; an outlet grid, the chipper unit and outlet grid configured so that the outlet grid forms an outlet for the vegetative debris within the casing, the outlet grid 13 and cutting means mutually configured so that the grid is located substantially directly adjacent to the cutting means in use, the cutting means configured so that in use at least part of the vegetative debris is forced through the outlet grid.

A device to reduce solid state drives (SSD) and the like digital media storage devices into particles less than 2 mm maximum edge length. The device is particularly adapted to disintegrating 1.8 and 2.5 solid state drives at a rate of about 360 HDD/hr or 720 SSD/hr with a throughput of about 10 seconds. A blade assembly is designed to provide multiple cutting angles while rotating at 520 rpm to maintain a low decibel rating.

The present disclosure concerns a device for granulating coarse material. Examples of course material include pulverulent solids such as powder, grain, or mixtures thereof. The device disclosed includes a rotor, a screen, and an automatic distance adjusting unit. The rotor is configured to rotate/oscillate and press the coarse material through the screen in order to produce a granulate with a smaller granulate unit size compared to the coarse material. The automatic distance adjusting unit is configured to adjust a distance between the rotor and the screen.

A material processing machine for material reducing operations. The material processing machine comprises an infeed system, a reducing system, and a discharge system. The reducing system comprises a rotor having processing tools to reduce the material within a reducing chamber. A colorizer system directs colorant from a colorant source towards the material reducing system within an outlet zone. The colorant colorizes the material being reduced within an inlet zone. The reduced material may be discharged through one or more screens within the outlet zone such that negligible colorant is applied directly to the reduced material. The material reducing operations may comprise a two-stage reducing operation in which the colorizer system is inoperable for the first stage and operable for the second stage. The screens may be selectively interchangeable between stages to incrementally reduce the material to provide substantially uniform colorizing and material size.

A foliage shredder that can shred inputted foliage matter into uniform sized particles without pulverizing the inputted foliage matter includes a housing, a shredding axle, a motor, a stand, a digital timer, a power cord, and a lid. The shredding axle is concentrically positioned within a cylindrical compartment of the housing and rotatably coupled to a rotor of the motor. A stator of the motor is externally connected to the housing and electrically connected to the power cord through the digital timer. The lid is terminally attached to the housing thus closing the cylindrical compartment. The cylindrical compartment functions as a container unit for the inputted foliage as the electrically powered shredding axle shreds the inputted foliage into uniform sized particles.

A seed grinder includes a housing that is configured to contain seeds and a buffer solution, a grinding mechanism that is positionable in the housing to grind the seeds in the housing, and a dispensing mechanism attached to the housing and configured to dispense the ground seeds and the buffer solution from the housing into a sample holder.
