Definitions

  • the invention relates to a device for controlling an inlet in a crusher with a rotatable in a crushing chamber about a vertical axis, preferably with internal channels to accelerate the material to be broken before it is thrown against a wall made of broken material or a baffle Rotor, and a funnel-shaped storage container.
  • centrifugal mill for grinding or grinding grain, core fruits or similar material has become known, which is fed to the mill from a loading device mounted on its top, which opens at the periphery of a grinding chamber delimited on the outside by a circular cylindrical sieve , which contains a vertical axis as well as a knife with several knife arms, which revolves around the vertical grinding chamber axis and is located in the vicinity of the grinding chamber floor.
  • a centrifugal mills are particularly unsuitable for grinding hard goods such as stones, since such goods produce a large amount of dust.
  • the object of the invention is to provide measures which prevent unnecessary air from being drawn in by the crusher and leading to the development of dust.
  • the regulation can take place according to the invention in that at least one slide which is adjustable transversely to the inflow direction is provided as a shut-off device.
  • two slides overlapping in the central region are provided, at least one of which is controllable.
  • the adjustable slide can be controlled manually.
  • the slide can be controlled by a probe which controls the size of the opening of the slide depending on the amount of material in the storage container.
  • the vertical crusher shown in the drawing has a feed container 1, which is essentially funnel-shaped and is preferably fed by a conveyor belt, not shown, or an, if necessary, adjustable trough.
  • the reservoir 1 is connected to a central inlet opening 2 or a cylindrical inlet port 2 'of an essentially cylindrical crushing chamber 3, in which one of the inlet port 2 centrally loaded crusher rotor 4 rotating about the central axis XX, which is driven by a motor located underneath it, rotates.
  • the rotor 4 has a central inlet, from which the material in the direction of arrows B reaches internal channels, in which the material to be broken is accelerated, whereupon it is broken on a baffle and subsequently on the material accumulating on the baffle .
  • This cementing layer on the baffle reaches a thickness until the material refracting on this layer falls through an opening 7 into a chamber 6 underneath. Dust from the material to be crushed also collects on the walls of the channels 14 and forms a hard protective layer.
  • the accumulated on the outer walls of the crushing chamber 3 formed as baffle plates can occasionally be used for maintenance work on the system or for other purposes, e.g. B. blown out or removed by hand.
  • the inlet opening of the crusher rotor is always closed by the incoming material.
  • the rotor can be equipped with internal channels 14 for accelerating the material to be broken before it is thrown against a wall made of broken material or an impact wall.
  • a feed container 1 is provided for introducing the material into the vertical crusher, in which the size of the inlet opening 2 can be regulated by at least one controllable shut-off device.
  • the motor 5 for the crusher rotor 4 is located in the chamber 6. From the chamber 6, the material passes through an annular funnel 8 to a collection point.
  • the size of the inlet opening 2 between the reservoir 1 and the inlet port 2 is controlled by at least one slide 10, in the present case there are two slides 10 ', 10''which overlap in the middle. Instead of such slides, any other type of shut-off device can occur. These slides 10 ', 10''can be controlled manually or automatically, at most only one of the two slides being controlled.
  • At least one of the slides 10 ', 10' ' is controlled by at least one probe 11 which detects the cross-section of the inlet opening 2, which releases the slides 10', 10 '', for the material to be shredded in the Form regulates that the material in the storage container 1 always closes the inlet opening.
  • Fig. 1 three material quantities characteristic of the control in the storage container 1 are indicated. I and II are minimum fill levels of the material quantity and III is a maximum fill level.
  • the slide 10 is closed.
  • the vertical crusher 4 is switched on.
  • the belt or the trough for loading the storage container 1 is switched on.
  • the slide opens intermittently until the motor of the vertical breaker has reached approx. 95% of the nominal current.
  • the task is reduced cyclically when the probe has determined the maximum fill level III and the nominal motor current has risen above 95%.
  • the loading system is e.g. the conveyor belt or the trough is put out of operation, whereupon the probe 11 closes the slide 10 when the material reaches level II. The entire system is then stopped.
  • the system according to FIG. 1 is mainly used when there is the possibility of regulating the feed quantity, i. H. Material e.g. to withdraw from a bunker.
  • the vertical crusher can always be kept in the full-load range and thus the size reduction always remains approximately the same.
  • a further area of application of FIG. 1 is when the amount of feed varies or cannot be kept constant.
  • the slide 10 is set manually in the case of continuous loading and not necessary regulation of the inlet opening 2, so that it is ensured that the level of the material in the storage container 1 always remains approximately constant and thus the inlet opening 2 always with Material remains closed in order to avoid unnecessary air intake and thus dust generation.
  • the system according to FIG. 2 is mainly used when the feed quantity is relatively constant or a regulation to max. Throughput is not required.
