    Abstract: Visual detection of food waste is used to control flow of flushing water to a food waste disposer. When the disposer is turned on, flushing water is also turned on at a low flow rate. The flushing water is directed into the food waste disposer. A visual detection sensor, which is coupled to a controller, is oriented to detect food waste entering the food waste disposer. Upon detection of the presence of food waste, the controller changes the rate of flow of the flushing water from the low flow rate to a high flow rate. The controller maintains the flow rate of the flushing water at the high flow rate for as long as food waste is detected as entering the food waste disposer and for a period after food waste is no longer detected to allow the food waste to be comminuted and flushed from the food waste disposer.

    Abstract: An integrated medical waste management and treatment system may include sensors, interlocks, communications links and/or other features for determining if the waste itself, the decontaminating disinfectant used in the process, or the status of the system are consistent with recommended or authorized system operation. System operation may be terminated if a condition inconsistent with recommended or authorized system operation is detected. Such compliance apparatus may include an electronic scale for determining the weight of the waste loaded into the receiver compartment, a metal detector, or a sensor for determining if the decontaminating disinfectant is a recommended or authorized disinfectant. A communications link may be provided one or more systems to transmit information to a central station to deliver updates or commands associated with the recommended or authorized operation of each system.

  • Publication number: 20130153694
    Abstract: A method is disclosed for controlling a mill system having at least one mill, e.g., an ore mill or cement mill, wherein electrical power is drawn from a power network to rotate at least one mill body for comminuting a material fed to the at least one mill body. One or more control variables of the mill system are regulated such that the power drawn from the power network corresponds to a predetermined setpoint power draw-off for the mill system. The method may provide control power in the power network for compensating for fluctuations in energy generation due to increased use of regenerative energies. The method may be used, e.g., to regulate high energy mill systems, e.g., tube mills, SAG mills, or ball mills, such that even relatively large quantities can be made available as control power in the power network.

  • Publication number: 20130146693
    Abstract: A shredder is disclosed. The shredder includes a housing having a throat for receiving at least one article to be shredded, and a shredder mechanism received in the housing and including an electrically powered motor and cutter elements. The shredder mechanism enables the at least one article to be shredded to be fed into the cutter elements. The motor is operable to drive the cutter elements so that the cutter elements shred the articles fed therein. The shredder also includes a detector that is configured to detect a thickness of the at least one article being received by the throat, and a controller that is operable to perform a predetermined operation responsive to the detector detecting that the thickness of the at least one article is at least equal to a predetermined maximum thickness.

  • Publication number: 20130134243
    Abstract: The present invention discloses a machine for shredding plastic container. The machine comprises a pressing device, a fixed plate having slits arranged in matrix pattern, where said plate is positioned at one end within the housing and said slits face the interior space of the housing, a movable plate having plurality of blades connected to at least one arm, wherein said plate is arranged to move along a central axis within the housing and said blades edges facing the sharp edges of said fixed plate where the blades configuration correspond to slits matrix pattern. When operating the machine the containers are placed in-between said movable plate and said fixed plate, such that when the movable plates moves along the central axis of the housing toward the fixed plate, the blades crash and cut/shear the container into flakes of predefined size suitable for recycling.

  • Publication number: 20130008985
    Abstract: The rotational speed of the drum of an ore mill may be controlled variably over time. By rotating the drum during a first time interval at high speed, especially hard or dense particles are broken up by tumbling. At the same time, the discharge characteristics of the mill are adversely affected. In a subsequent second time interval, the drum is rotated at a slower speed, and the material is discharged more effectively, whereas the tumbling movement inside the mill is not achieved. The combination of said different modes of operation within short time periods in continuous operation may improve both the comminution as a result of a tumbling motion of the material and also the discharge of the ground material. By regulating the rotational speed with different target values within short time windows, different requirements for the movement behavior of the material to be ground and for the discharge characteristics of the ground material can be simultaneously optimised.
