Definitions

  • the invention relates to a device according to the preamble of claim 1.
  • Such a device is known from DE-OS 34 04 730.
  • the two feed rollers of this known device are driven in the same direction.
  • the direction of rotation is defined in such a way that the material fed from above passes from the top of one feed roller to the top of the other feed roller which is driven in the same direction.
  • the amount of goods taken along is achieved by means of a slide arranged above the first feed roller, which is also referred to as a "feed bar".
  • This slide is stationary, ie it cannot move relatively with the regrind. This allows regrind to accumulate in front of the pusher, reducing throughput and making it uneven.
  • the invention has for its object to provide a device according to the preamble of claim 1, which ensures a uniform and continuous flow of the ground material which is fed to the rolling mill.
  • the regrind should also be dissolved if lumps or the like have formed.
  • the ground material is forcibly drawn into the gap between the feed rollers.
  • the slide in the invention is replaced by a feed roller, the surface of which moves relatively with the flow of the ground material. Both superposed feed rollers move in the direction of the regrind to be dosed and dissolved. Lumps are prevented from collecting in front of the gap as these are broken up. A constant volume flow is generated, which is independent of the specific weight. The flow of the regrind does not pulsate, but is even, so that a correspondingly continuous, even stream of regrind is fed to the subsequent rolling mill.
  • the device shown in the drawing consists of a feed housing 1, in which two feed rollers 2 and 3 are supported by means of shafts 5 and 6. A gap 4 is formed between the feed rollers.
  • Tooth profiles 8 are formed on each feed roller, which have a slight twist in the longitudinal direction, i.e. they form a corresponding screw shape. As can be seen in FIG. 2, the teeth of the two feed rollers are offset from one another in cross section.
  • the tooth profiles 8 can be arranged on interchangeable sleeves on the respective feed roller. It is easy to see that the tooth shape must be adapted to the respective regrind.
  • the offset of the tooth profiles 8, which can be seen in cross section, can also be adjusted to adapt to the ground material.
  • Each feed roller 2, 3 is supported by means of a shaft 7 and 8.
  • the feed housing lies at 9 close to the lower feed roller 3 in order to prevent unaffected passage of the ground material in this area.
  • the regrind that comes into this area due to the force of gravity is carried along by the feed roller 3 and conveyed into the roll gap 4.
  • the shaft 6 of the lower feed roller 3 is mounted in the two side walls of the feed housing 1.
  • the shaft 5 of the upper feed roller 2 is mounted in two swing arms 10, the fulcrum of which is designated by 16 on the side walls of the feed housing 1.
  • the two swing arms are connected to one another by a crossmember 11.
  • An adjusting screw or spindle 13 is attached in the crossmember 11 and can be moved up and down by rotation. Locking nuts are designated 14.
  • a pneumatic cylinder 12 for closing the gap between the feed rollers when the machine is at a standstill.
  • the regrind is fed into the feed housing 1 from above by gravity. There it is gripped by the counter-rotating feed rollers 2 and 3 and drawn into the gap 4. Dosing takes place depending on the size of the gap and the peripheral speed of the feed rollers. At the same time, lumps and the like are dissolved, since both surfaces of the feed rollers 2 and 3 move with the regrind in the direction in which the conveying is to take place.
  • the correspondingly selected and set tooth profiles also ensure that the flow rate is evened out.
  • the mounting of the upper roller with the aid of the swing arms 10 prevents destruction.
  • the upper roller is moved upwards against the action of the springs 15 until the foreign body has left the gap 4. This movement can also be used as an indicator which informs the operator that a foreign body has been moved through the gap 4.
  • the adjusting screw or spindle 13 is used to adjust the gap 4.
  • the corresponding end of the adjusting screw 13 lies against the end of the piston of a pneumatic piston and cylinder unit 12.
  • the ends of the piston and the adjusting screw practically form the fixed or setting point.
  • the pneumatic piston and cylinder unit 12 is actuated to close the gap 4, i.e. the springs 15 are allowed to move the cross member 11 upwards and thus the feed roller 2 downwards.
  • the actual rolling mill which is not shown, connects to the feed housing 1 at 7 (FIG. 2).
