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; an agitator that is disposed within the hopper and is movable in a first rotational direction that moves organic waste downward and in a second rotational direction that moves organic waste upward; a motor configured to selectively move the agitator in the first and second rotational directions under control of the controller; and a side grinding and drainage system disposed toward the bottom end of the hopper and preferably on a tapered portion of the hopper for grinding and liquefying organic waste.

The present invention relates to a system and process carried out after a process of separating fragments of steel from pieces of ore that come out of a semi-autogenous grinder for grinding ores, and which consists of a system formed by one or more instruments for capturing images, each one being sensitive to light of different wavelengths, which point to the surface of an element for receiving the steel fragments or a channel that receives the steel balls and the fragments thereof from the separation process, through which the steel balls and fragments thereof move when they are discharged from this process, with the possibility of directing each image sensor such that it is not parallel to the others.

By digitally processing the images obtained with the one or more sensors, the dimensions and morphology of the balls and ball fragments discharged from the separation process can be determined.

The present invention concerns the field of safe disposal or recycling of devices which include flat panel displays (FPDs) such as televisions, public information screens and signs, advertising panels, computer monitors and lap-tops, tablets and computers with integrated flat panel displays. The invention provides an apparatus for the disassembly of flat panel display units (FPDs) which each comprise a display screen provided on the front face of the FPD and a housing which accommodates the screen and associated electronic circuitry, the apparatus comprising: (i) a cutting station for receiving an end-of-life FPD, the cutting station being configured and arranged to make cuts into the FPD along cutting paths which permit detachment of the entire display screen, or a cut-out sub-unit of the display screen, from the FPD, (ii) an FPD characterisation station provided in advance of, or at, the cutting station, the characterisation station being adapted to measure and/or log one or more characterising parameters or identifiers of the FPD in advance of the cutting step, (iii) a data processing system in data communication with the FPD characterisation station, the data processing system being adapted to receive and one or more of said parameters or identifiers, and derive therefrom an appropriate protocol for cutting the FPD display screen, and provide instructions in accordance with the protocol which are sent back to the cutting station so as to control the cuts. An FPD database may be associated with the data processing system, the FPD database being pre-loaded with cutting path instructions for a range of known FPDs.

A method determines the bulk density of bulk material (2) in a mobile crusher, in which the bulk material volume of bulk material (2) delivered onto a conveyor belt (1) is determined. The method is configured such that the bulk material weight can be determined reliably over a relatively prolonged operating period of a mobile crusher, even with varying bulk material density. Both the bulk material volume and the bulk material weight of a conveyor belt section (3) are sensed in successive time steps, and the bulk density is determined from the quotient of the bulk material weight and the bulk material volume.

A method for detecting wear in crushers, having a wearing part (2) mounted on a drive shaft (1), during idle operation is described in which downtimes that impair crusher productivity can be eliminated and nevertheless reliable wear detection is made possible with low risk of injury to machine operators. The drive shaft (1) is accelerated from a starting angular speed (oil) to an end angular speed (ω2) with a specified acceleration, and the drive energy required for this is ascertained, whereupon the wear of the wearing part (2) is ascertained as the value assigned to the required drive energy in a specified wearing-part characteristic curve (3, 4, 5).

A method for controlling a crusher having a crushing tool and a vibratory conveyor (1) having a drive (5), includes capturing bulk material (2) in a capture region (4) using a sensor (3). So that, in the case of grains with an inhomogeneous grain size distribution, even large grains can be crushed with a constant crushing result without a risk of the crusher being damaged, an effective diameter d.sub.eff, which results from the largest diameter d.sub.max and the direction (9) thereof, transverse to the conveying direction (8) of a grain of the bulk material (2) is determined as the controlled variable in the capture region (4). If the effective diameter d.sub.eff exceeds a predefined power threshold value, the power of the crushing tool is increased and/or, if the effective diameter d.sub.eff exceeds a predefined switch-off limit value, the drive (5) is switched off.

Embodiments disclosed herein provide an organic matter processing apparatus and method for the use thereof to convert organic matter into a ground and desiccated product. This can be accomplished using a bucket assembly that can grind, paddle, and heat organic matter contained therein. An air treatment system is provided to treat the air interacting with the organic matter. The processing apparatus is outfitted with sensors and switches that provide feedback data to a processing unit and a safety monitor. The feedback data is used to monitor the operating conditions and the status of various components, as well as control the operation of the processing apparatus. In addition, the feedback data is used to enforce a safety protocol.
