A portable grinding/shredding/chipping system with a drive track assembly which is manipulatable to facilitate altering the orientation of the portable grinding/shredding/chipping system. This arrangement results in improved loading and processing, of both long and short materials, as well as facilitates connection of a transport dolly and a transport truck/tractor without requiring any additional lifting mechanism. A pivotable housing provides greater access to the rotor and has an over-center arrangement which prevents the pivotable housing from inadvertently moving or pivoting back into engagement with the rotor. The portable grinding/shredding/chipping system is provided with a belt drive assembly which facilitates modification of the rotational speed of the rotor by merely replacing a sheave of the belt drive assembly. Lastly, both head and tail pulleys are driven by a respective motor so that a catinary of the discharge conveyor is radiussed which shortens an axial length of the system.

A method for the destruction of data carriers preventing access to the process of rendering confidential data carriers, which consist of paper or similar material, unreadable and allowing the carriers to be destroyed. In the method, confidential data carriers are collected at the point of origin in secure collection containers, removed by a collection vehicle, and are supplied to a paper recycling plant in a final step. The interior of a mobile pulper, which is connected to the collection vehicle, is filled with the confidential data carriers, the carriers are mixed with a pulping fluid and the mixture is blended by an agitator to form a suspension of defibrated documents and pulping fluid, a hydromechanical pulping process taking place in the pulper before the suspension is supplied to the paper recycling plant.

A wood grinding machine may have a vibration detection system including one or more vibration sensors. The vibration detection system may include a trip point representative of a maximum allowable level of vibration. If a vibration signal from the one or more vibration sensors exceeds the trip point, a trip protocol may be executed to automatically stop the grinding process. Related methods are also disclosed.

The invention relates to a conveyor belt arrangement of a material processing device having a conveyor belt (20) and a receiving and adjustment mechanism for adjusting the conveyor belt between a transport position and a working position. To this end, the conveyor belt is mounted on bearing elements (40, 60), which are rotatably connected to receiving elements (30, 50) of the receiving and adjusting mechanism. According to the invention, the receiving elements are each coupled to a pivot bearing each having a pivot axis (30.1, 50.1) for the pivotable attachment to the material processing device, and at least one bearing element is connected to the conveyor belt in a linearly adjustable manner, and/or between the conveyor belt and the pivot bearing of at least one receiving element, a compensating mechanism is provided, by means of which a spacing change between the bearing elements can be compensated for. The conveyor belt arrangement allows the simple adjustment of the conveyor belt of a material processing device between a working position and a transport position.

A compact modular mobile aggregate processing system configured with no stand-alone inter-plant conveyors for decreasing the footprint of the system and an infinitely adjustable flow diverter(s) for increasing the control of and variation of output characteristics of the system; the system further including specialized folding conveyors.

The invention relates to a method for mining and processing of an ore. The method comprises at least one mobile comminution device (26) comprising at least one mobile crusher unit and at least one mobile grinding unit located proximate to an ore body that is being mined (20), fragmented ore (22) from the ore body is comminuted in the mobile comminution device (26) to a size which can be readily pumped (28) without the use of special carrier fluids, preferably to a particle size p50 in the range between 0.05 to 1 mm and the comminuted ore is combined with water to form a slurry.

A horizontally fed disk grinding system includes a tray coupled to a trailer for receiving bulk material. The system further includes a grind hub coupled to the trailer and a cutter disk coupled to the grind hub. The grind hub is structured to rotate about a grind hub axis and the cutter disk is structured to rotate about a cutter disk axis and about the grind hub axis. A grind ring is coupled to the trailer and is structured to slide to engage the grind hub during use. A plurality of plates are coupled to the tray and structured to oscillate to feed material from the tray to the grind hub and the cutter disk, where the material is reduced to particulate form. The grind hub further includes an outlet and a conveyor rotatably coupled to the trailer to convey the particulate material away from the outlet to a selected location.

A mobile mineral material processing plant is adaptively coupled to a screen module using an elongated coupling base that has first and second adapters to respectively detachably attach together a screen module, one or more exit conveyors and to detachably attach the screen module and the one or more exit conveyors to the plant. The first adapter pivotably couples to the plant on laterally moving the plant to engage with a first connector of the first adapter. The second adapter allows an actuator to lift the screen module with the coupling base so that the screen module pivots from ground about the pivotable coupling to an inclined operating configuration. The coupling base is angled to horizontally align a reject conveyor in the inclined operating configuration.
