  • Publication number: 20240139753
    Abstract: A material processing unit has a movable tool accommodated in a housing. The housing includes a housing part which can be moved between an open position and a closed position relative to a further housing part. A safety device prevents any opening of the housing when the tool is driven and/or prevents any driving in the open position. The safety device includes at least two actuators and a controller. A first actuator locks the housing part in the closed position. A second actuator causes, supports and/or permits a movement of the housing part. Sensors are assigned to the actuators. A controller is designed to control the drive and the actuators and to receive the actuation states detected by the sensors. A method for opening/closing a housing of a material processing unit is also provided.

  • Publication number: 20240139751
    Abstract: The invention relates to a crusher unit (10), in particular an impact crusher, having an impact rotor (11), having at least one swivel-mounted impact rocker (20), wherein a crushing gap (15) is formed between the impact rotor (11) and the impact rocker (20), wherein the impact rocker (20) can be swiveled along an adjustment path by means of at least one gap-adjusting means (30) to set a gap width of the crushing gap (15), wherein the impact rocker (20) is mounted such that its weight force acts in the direction of a reduction of the crushing gap (15). For a high degree of operational safety, the crushing gap can be readjusted during operation in that at least one retaining device (50) is provided, which uses a retaining force to flexibly counteract a swiveling of the impact rocker (20) in the direction of the impact rotor (11). The invention also relates to a method for setting the crushing gap (15) of a crusher unit (10).

  • Patent number: 11925939
    Abstract: A method of determining wear of a rotary impact crusher includes adjusting the position of an impact rocker relative to an impact rotor with an actuator by a first adjustment value until a crushing section of the impact rocker contacts an impact bar or an impact circle of the impact rotor. The first adjustment value is compared to a first reference value to make a first comparison corresponding to total wear of the impact rocker and the impact bar. The position of the impact rocker is adjusted relative to the impact rotor by a second adjustment value until the impact rocker contacts a reference measurement section. The second adjustment value is compared to a second reference value to make a comparison corresponding to wear of the impact rocker.

  • Publication number: 20220097076
    Abstract: The invention relates to an impact crusher having a crusher unit (20), which has an impact rotor (30), wherein the impact rotor (30) bears at least two impact bars (35), wherein the impact bars (35) having a radially outer end (35.1), wherein the radially outer end (35.1) of at least one of the impact bars (35) forms an impact circle (K), wherein at least one impact rocker (41, 42) is assigned to the impact rotor (30) such that, in an operating position, a crushing gap is formed between the impact circle (K) and a crushing section (41.6) of the impact rocker (41), wherein for setting the crushing gap, first the crushing section (41.6) of the impact rocker (41) is adjusted by means of an actuating unit (50) in a feed direction by a first adjustment value such that it contacts a contact point of the impact bar (35), in particular the radially outer end and/or the impact circle, wherein the first adjustment value is compared to a first reference value in a controller, and wherein the crushing section (41.

  • Patent number: 9222556
    Abstract: A spindle drive has a spindle nut (1) and a threaded spindle (2) mounted in a rotationally fixed and axially displaceable manner on a reference body (3) by way of a linear guide, wherein the axis (9) of the threaded spindle (2) is arranged parallel to the longitudinal direction of the linear guide, and wherein the linear guide has a groove (4) and a guide element (5) engaging in the groove and comprises an elastic region (5b, 5b?, 5b?), the width of which perpendicular to the longitudinal direction of the linear guide is greater than the maximum groove width in the region used for the linear guide.
