The present application provides a convenient and quickly-assembled rotary composting barrel and a quick assembly method thereof. On the one hand, the solution provides a convenient and quickly-assembled composting barrel, which comprises two lateral plates, a bearing plate and several surrounding plates, wherein the lateral plates and the bearing plate are respectively provided with the first clamping grooves and the second clamping grooves, and nuts are pre-installed in the first clamping grooves and the second clamping grooves, and the surrounding plate is provided with through-holes through which bolts penetrate at corresponding positions; on the other hand, the solution provides a quick assembly method of the rotary composting barrel, in which by screwing bolts with pre-installed nuts, the bearing plate is connected with the surrounding plate first, and then the lateral plates are connected with the surrounding plates at both sides quickly. The existing rotary composting barrel is inconvenient and time-consuming to install. The rotary composting barrel involved in this solution is ingenious in structural design. It is very convenient to install, and the assembly time is shortened by more than half. It is skillful and environment-friendly when used in conjunction with an unloading cart.

Purpose of separating solid garbage, oil and water simultaneously is realized.

A method and system for coal ash reclamation from a land fill, the system comprising: a harvester; a screen for screening non-ash material from ash collected by the harvester; a dryer for drying raw ash thereby creating dried coal ash and fine particulate ash; an exhaust pipe to direct the ash to a dust collector; a crusher for crushing the dried ash; a classifier for classifying the crushed dried ash; and a storage container for storage. The method comprising: harvesting raw coal ash from a land fill; screening the raw coal ash to remove oversize materials; drying the screened ash to remove water; crushing the stream of dried ash; classifying the crushed ash into fine particulate ash and large particulate ash, the second stream being directed for further crushing; streams of fine particulate ash being cooled; and storing the fine particulate ash.

A liquification system for an organic waste management system includes a hopper that is oriented vertically such that organic waste added to the hopper is biased by gravity toward a bottom end of the hopper; a fixed grinding plate disposed at the bottom end of the hopper and including grinding elements for grinding and liquefying organic waste; an agitator that is disposed within the hopper and is movable relative to the grinding plate in a first rotational direction that moves organic waste downward toward and against the grinding plate and in a second rotational direction that moves organic waste upward toward a top end of the hopper; a motor configured to selectively move the agitator in the first and second rotational directions under control of the controller; and an outlet through the bottom end of the hopper through which liquified organic waste drains from the hopper.

Embodiments disclosed herein provide various systems and methods for obtaining organic matter data related to the processing of food matter and mixed organics in an organic matter processing apparatus. The organic matter data can include, for example, mass values, water content values, timestamps, account numbers, other quantifiable metrics, and other identifying information. The organic matter data can be used according to many different embodiments. For example, in one embodiment, the organic matter data can be provided to a central system that processes the data for use by a third party such as a matter collector or an end user of output produced by the organic matter processing apparatus. In another embodiment, organic matter data can be presented to a user of the organic matter processing apparatus.

The present invention relates to a device for treatment of a material mixture consisting of substitute fuel and impurities, having a vertically aligned central feeder (1), a separating unit (2) arranged underneath the central feeder (1), a rotor mill (3), wherein the rotor mill (3) is arranged above the separating unit (2) and surrounds the central feeder (1), a flow device (4) for generating an upwardly directed gas flow, wherein the rotor mill (3) has a multistage design, and a respective separating device (6) is arranged between the stages (5.1, 5.2) of the rotor mill (3), wherein material mixture not held back by the separating device (6) is further comminuted in the following stage (5.2).

A vehicle can be equipped with a size reduction device whereby input is directed, such as with a loading system, up and into an inlet of the size reduction device or a storage body to await loading into the size reduction device, such as with a transfer system. The input is reduced in size to be particulate and then either discharged from an outlet or into a storage body for later removal, possibly with a transfer system.

Disclosed herein are systems and methods for processing waste egg shells into (i) a first product including calcified egg shell particles having diameters of 3μ or less, and (ii) a second product including calcified egg shell particles having diameters in a range from about 3μ to about 7μ. The first product may be used as a CaCO.sub.3 substitute for paint compositions and plastics compositions. The second product may be used as a CaCO.sub.3 blasting media substitute for use with abrasive blasting equipment.

Proposed is a food waste disposal apparatus for automatically discharging food waste by compressing (naturally dewatering), cutting, and drying food waste. More specifically, proposed is a food waste disposal apparatus having a corrugated part provided at an input hole so that same can be bent in all directions, and thus construction is facilitated, and having, at a predetermined distance away from a drying drum that generates high heat, an exhaust fan for discharging internal air of a drying and discharging part, so as to minimize breakdown of the exhaust fan caused by high heat, and enable vibration and noise of the exhaust fan to be prevented.
