  • Patent number: 9884323
    Abstract: An auto-feed paper shredder operates by using counter-rotating belts to grasp sheets of paper from the bottom of a stack of paper and push the sheet into a shredding mechanism. Successive sheets are pulled from the stack and shredded so that an entire stack of several hundred sheets can be shredded without operator intervention. The belts that accomplish the auto-feeding are housed in roller belt assemblies that can be easily removed from and reinserted into the paper shredder. In this way when the belts become worn and no longer effectively grasp the paper, the user simply removes the assembly and inserts a new one. The worn assemblies can be returned to the manufacturer to be refurbished.

    Abstract: A system for regulating a dump rate of a truck is disclosed. The truck is configured to carry material and dump the material in a container. The system includes a first detection module and a controller in communication with the first detection module. The first detection module generates a signal indicative of a draw down rate of the container. The draw down rate corresponds to a rate at which the material is discharged from the container. The controller determines the draw down rate of the contained based on the signal received from the first detection module. The controller further determines a level of the material within the container based on the draw down rate. The controller then regulates the dump rate of the truck based on a relationship between the level of the material within the container and a threshold level.

  • Patent number: 8706287
    Abstract: The invention related to a control system for a mill, particularly a roller grinding mill, comprising a mill control device (11), which is designed to control at least one mill characteristic on the basis of an associated target variable, and a fuzzy-control device (13), which is connected to the mill control device (11) and designed to adjust the target variable of the at least one mill characteristic to be controlled when at least one operating parameter of the mill deviates from a predefined normal range as a function of fuzzy rules that are based on said at least one operating parameter of the mill until the at least one operating parameter of the mill has reached the predefined normal range again. A solution is to be provided, which enables automated optimized mill operation even with changing operating conditions, particularly a mill operation that prevents the “mill rumbling”.

  • Patent number: 8695904
    Abstract: A mobile crushing station for receiving and comminuting excavated material from earth moving vehicles provides at least one moveable skip connected to a chassis or frame for receiving material from vehicles, such as rear unloading vehicles like dump trucks. The skips are configured to move to dump material fed into the skips into a feed hopper. The feed hopper is positioned to guide material onto a feed conveyor, such as an inclined apron conveyor. The feed conveyor is configured to transport material to a feed orifice of a crushing device, such as a sizer, a crusher, or a crushing circuit. The crushing device is configured to crush material fed into the crushing device. The crushing device also has a discharge orifice that is positioned above a portion of a discharge conveyor. The mobile crushing station is moveable so it may be repositioned closer to an excavation site as excavation activities progress.

  • Publication number: 20140042254
    Abstract: A paper shredder with an allowable thickness warning function is provided. The paper shredder includes a casing and an upper cover. An input tray is disposed on the casing for placing plural papers thereon. A pressing member and a thickness detecting device are installed on the upper cover. When the pressing member is contacted with the plural papers on the input tray and pushed by the plural papers, the pressing member is moved. The thickness detecting device is located near the pressing member. Moreover, in response to the movement of the pressing member, the thickness detecting device may be triggered. If an overall thickness of the plural papers exceeds an allowable thickness, the pressing member is pushed by the plural papers. Consequently, the thickness detecting device is triggered by the pressing member to generate a warning signal.

    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.
