Definitions

  • the invention relates to a device for coarse comminution of ceramic masses, medium-hard rocks or the like, with two knife rollers rotatably mounted in a machine stand, each of which can be driven by its own, reversible drive and the roller gap of which can be adjusted by shifting a roller parallel to itself.
  • the device stops. Then the piece of material must be removed from the device. Because of the poor accessibility of the working area of the device, such removal is only possible via the loading area and, depending on the size of the piece of material that inhibits the size reduction process, is very time-consuming. The machine cannot be used for shredding during downtime. In addition, it is extremely dangerous for an operator to manually intervene in the work area of the device, as is required in some machines to remove oversized pieces of material.
  • the invention has for its object to design a device of the type mentioned in such a way that pieces of material that cannot be comminuted can be automatically ejected, thereby stopping the device and avoiding a safety risk.
  • Claim 1 serves to achieve this object.
  • the device according to the invention by changing the height, in particular lowering the movable roller parallel to itself, at the same time and automatically the opening of a side opening in the machine stand and reversing at least one roller and ejecting a piece of material which cannot be comminuted through the opening is effected, without stopping the device and without manual intervention by an operator.
  • a flap is arranged on the machine stand for releasing and blocking the opening, the opening and closing movement of which is coupled with the lowering and lifting movement of lifting elements for displacing the movable roller, preferably mechanically via a lever mechanism which, when the movable roller opens the flap and closes again when it is raised to the normal operating position.
  • the actuating means for opening and closing the flap can also be provided independently of the lifting elements for displacing the roller, for example in the form of separate electromechanical, hydraulic or pneumatic lifting elements.
  • the cutter disks are axially offset on the two rollers so that the knives of one roller follow the roller grooves face the other roller so that the knives can engage in the roller grooves of the other roller.
  • two knife rollers 3, 4 are mounted axially parallel in parallel legs 11, 12 of a U-shaped machine stand 1 and are provided with knives 5, which are radially and axially spirally aligned on ring-shaped knife disks 31, 41 and have knife edges pointing in opposite directions in the circumferential direction.
  • the knife disks 31, 41 are separated by spacer rings which form roller grooves 51.
  • Each roller 3, 4 is driven hydraulically, electromechanically or pneumatically by a separate motor 2.
  • the roller 4, which is displaceable in sliding blocks 42 in parallel radial, vertical or oblique slots 13 in the legs 11, 12, can be lifted relative to the other fixed roller 3 by means of two lifting elements 7, such as hydraulic cylinders, spindle lifting elements, pneumatic cylinders or similar elements and lower. This leaves the roll gap s is infinitely variable.
  • a flap 8 is pivotally mounted between the legs 11, 12 about a hinge 81, which are connected to the movable roller 4 via a lever mechanism 6 or opened or, as required, by separate hydraulic, pneumatic, mechanical or electromechanical lifting elements can be closed.
  • the direction of rotation of the rollers 3, 4 is reversed several times in order to loosen the piece of material, rotate it into a different position and break it.
  • this piece of material M must be discarded.
  • the movable roller 4 is then automatically lowered by the lifting elements 7 according to FIGS. 3 and 4 until the axes A-A, B-B of the two rollers lie in an inclined plane E-E which is inclined downwards at an angle ⁇ .
  • the flap 8 is automatically pivoted upward via the lever mechanism 6 in order to open a lateral opening 15 in the machine stand.
  • Both rollers 3 and 4 now rotate in the same direction in the direction of the opening 15 and thus throw the piece of material that cannot be comminuted out of the machine into a container or onto a conveyor belt.
  • the roller 4 is raised by the lifting elements 7 until the desired small roller gap s is reached again.
  • the side flap 8 simultaneously closes the opening 15; the machine is ready for operation again.
  • the knife roller gap s can be so small that the knife disks 31, 41 almost touch, the knives 5 of one knife roller mutually engaging in the roller grooves 51 of the other knife roller.
  • Such a minimal setting of the roller gap s leads to a cleaning of the roller grooves 51 and thus to an improvement in the size reduction effect.
  • the device described enables a fully automatic rejection of material pieces M that cannot be comminuted, avoiding long downtimes and manual activities, and setting the roller gap s to a minimum value, which effects an effective cleaning of the roller grooves 51 by the knives 5 and optimizes the comminution effect.
