Abstract:
The present invention discloses low cost, on-site, efficient, and compact (stationary or mobile) system for continuous (non-batch operation) conversion of waste to usable products such as sources of energy, fertilizer, etc.
Abstract:
An auger system adapted to shred large materials. An exemplary embodiment is comprised of dual opposing augers that are adapted to grab, compress, and shred the material, reducing the material size such that it may be discharged through a side outlet opening and/or an extrusion tube into, for example, a standard roll-off compaction container. An exemplary embodiment allows large material to be processed in a low speed device with reduced equipment dimensions, providing operator safety with low profile loading, lower noise level, reduced chances of material being expelled from the processing chamber, and ability to use conventional material transport (e.g., semi-trucks).
Abstract:
A machinery (1) for collecting and treating waste, in particular solid urban waste, comprises an outer containing casing (2), which houses a processing chamber (3), in which the disposed waste is treated to produce two fractions and separate them from each other; and a holding chamber (4), connected to the processing chamber (3) and which receives and separately accumulates the two produced fractions; the processing chamber (3) comprises at least one waste separation part (9) provided with separation means (17), configured so as to separate the waste into an organic wet fraction and into a residual dry fraction directly in the machinery (1) and to accumulate the two fractions in respective compartments (21, 22) of the holding chamber (4).
Abstract:
The process for handling waste material comprises the steps of: supplying a waste material (M) having a first fraction (I) with high toughness and a second fraction (II) with low toughness, both of substantially rough particle size; grinding the waste material (M) by means of a grinding phase in a mill with loose grinding bodies (6) substantially ineffective on the first fraction (I) and substantially effective on the second fraction (II), the particle size of the second fraction (II) at the end of grinding being substantially fine; extracting the first fraction (I) and the second fraction (II) from the mill (4) by means of a gaseous flow that crosses the mill (4) and is suitable for extracting the first fraction (I) and the second fraction (II) when their bulk density is substantially equal to or lower than a pre-set bulk density; separating the first fraction (I) substantially rough from the second fraction (II) substantially fine.
Abstract:
A method of treating municipal solid waste comprising the steps of : shredding the waste to a first particle size,- storing the shredded waste in an aerated storage bay (14) for a first period time; shredding at least some of the waste to a second particle size,- and agitating the shredded waste in a rotating drum (19) for a second period of time and then outputting the treated waste; wherein biological decomposition under aerobic conditions takes place in the aerated storage bay and the rotating drum.
Abstract:
A high crushing efficiency medical waste treatment machine includes a crushing cylinder, a crushing knife set provided at the bottom of the crushing cylinder, an intermittent material discharge mechanism set on one side of the crushing knife set, a pressurizing mechanism slidingly set along the axis of the crushing cylinder on the other side of the crushing knife set. The pressurizing mechanism includes a mounting frame slidingly connected to the inner wall of the crushing cylinder, the mounting frame rotatably connected to a material tumbling plate made of magnetic material; when the intermittent material discharging mechanism discharges material, the pressurizing mechanism moving in a direction close to the crushing knife set; when the intermittent material discharges mechanism stops discharging material, the material tumbling plate rotates.
Abstract:
A plant for the processing of waste includes an outer housing and a grinding cell, in which a grinding chamber is defined having at least one inlet opening for introducing the waste to be processed, and at least one outlet opening for discharging the material resulting from waste processing. The openings are associated with a corresponding closure element, adapted to isolate the grinding chamber from the outer environment. The outer housing defines therein a space receiving the grinding cell and integrally surrounds the grinding cell, and in which the space is accessible through at least one door.
