  • Patent number: 12616978
    Abstract: A mineral processing plant for crushing mineral material or the like, using a crushing device and an internal combustion engine. In a first mode of operation an internal combustion engine is mechanically coupled to the crushing device to drive the latter. A generator is provided, which is mechanically coupled to an internal combustion engine to drive this generator, and the generator is coupled to one or more auxiliary units to supply to supply electric power thereto.

  • Publication number: 20250269384
    Abstract: A mobile material processing plant has an internal combustion engine and an electric motor. The internal combustion engine can be selectively coupled to or uncoupled from a mechanical drive train by an internal-combustion-engine clutch and the electric motor can be selectively coupled to or uncoupled from the mechanical drive train by an electric-motor clutch. The drive train has at least one output, wherein a crusher unit, is driven by the output. A transfer case has a main shaft. The internal combustion engine may be selectively coupled to and uncoupled from the main shaft by the internal-combustion-engine clutch and the electric motor may be selectively coupled to and uncoupled from the main shaft by the electric-motor clutch. A plurality of outputs may be coupled to the main shaft by means of which outputs at least the crusher unit can be driven.

  • Publication number: 20250269710
    Abstract: A drive for a mobile material processing plant includes an internal combustion engine and an electric motor. The internal combustion engine can be selectively coupled to or uncoupled from a mechanical drive train by an internal-combustion-engine clutch and the electric motor can be selectively coupled to or decoupled from the mechanical drive train by an electric-motor clutch. The drive train has an output end having at least one output. The internal-combustion-engine clutch and the electric-motor clutch are operatively interconnected by a shift device such that, in an internal-combustion-engine mode, the shift device uses the internal-combustion-engine clutch to couple the internal combustion engine to the drive train and decouples the electric motor from the drive train, and in that, in an electric-motor mode, the shift device decouples the internal combustion engine from the drive train and uses the electric-motor clutch to couple the electric motor to the drive train.

  • Publication number: 20250269721
    Abstract: A drive for a mobile material processing plant includes an internal combustion engine and an electric motor. The internal combustion engine can be selectively coupled to or uncoupled from a mechanical drive train at its drive end by an internal-combustion-engine clutch and the electric motor can be selectively coupled to or uncoupled from the mechanical drive train by an electric-motor clutch. The drive train has an output end having at least one output, wherein at least one machine unit, in particular an electric generator, is driven by the output(s). The at least one machine unit may be coupled to or uncoupled from the output by a shiftable machine-unit clutch, and the electric-motor clutch or the internal-combustion-engine clutch may be operatively connected to the machine-unit clutch via a coupling, in particular a mechanical or hydraulic coupling.
