  • Arrangement for processing dust
    Patent number: 7987929
    Abstract: The invention relates to a method for processing dust when breaking rock, to a dust separator, and further to a rock-drilling rig. Rock material and air sucked from a borehole or some other operating location is separated from each other in the dust separator. The separated rock material falls into a discharge part of the dust separator, from which it can be dosed in batches into a discharging device. The discharging device comprises a closed compression space in which the rock material batch is compressed into a more compact state. This forms a solid matter cake that is removed from the dust separator.

  • Measuring device, rock breaking device and method of measuring stress wave
    Patent number: 7895900
    Abstract: The invention relates to a method of measuring a stress wave and to a measuring device and a rock breaking device. A percussion device (7) gives impact pulses to a waveguide (21), where a compression stress wave and a reflected tensile stress wave are generated, which propagate in the waveguide. The compression stress wave causes an extension in the waveguide and the tensile stress wave a thinning, in which case properties of the waveguide may be determined by measuring geometric changes in the cross section of the waveguide. The measurement data are utilized in controlling the rock breaking device.

  • Pressure-fluid-operated percussion device
    Patent number: 7878263
    Abstract: A pressure-fluid-operated percussion device includes a frame allowing a tool to be arranged movably in its longitudinal direction. Pressure liquid is fed to the percussion device and returned to a pressure liquid tank. A stress pulse is produced in the tool utilizing pressure of the pressure liquid. A pressure liquid source maintains pressure in the working pressure chamber. Pressure liquid is intermittently fed to the percussion device such that the pressure liquid pushes a transmission piston into a predetermined backward position. Pressure liquid is alternately discharged rapidly from the percussion device so that the pressure of the pressure liquid in the working pressure chamber and the pressure liquid flowing from the pressure liquid source pushes the transmission piston towards the tool, generating a stress pulse in the tool.
