Definitions

  • the invention relates to a roller mill according to the preamble of claim 1.
  • the invention is particularly suitable for roller mills, which are provided for grinding of raw coal.
  • Roller mills which roll a grinding bowl or a grinding plate with a grinding track and with spring-loaded grinding rollers which roll on the grinding track or on a grinding bed formed thereon feed material, are used for the comminution of various materials ( DE 102 24 009 B4 . DE 31 003 41 A1 and DE 31 34 601 C2 ).
  • the feed material which is comminuted in a grinding gap between the grinding rollers and the grinding path, can be fed to the grinding chamber and the rotating grinding bowl laterally or centrally.
  • the comminuted material to be ground in an ascending gas stream for example an air stream which reaches the grinding space via a blade ring at the circumference of the grinding bowl, is fed to a sifter arranged above the grinding space. Fine material is discharged in the gas stream, while the coarse material particles are rejected in the classifier and returned via a semolina cone with a bottom cone opening to the central region of the grinding bowl and get under the grinding rollers for recalculation due to the flying force effect.
  • a central feed or task of material to be comminuted in vertical roller mills is carried out vertically from above into the center of the grinding bowl through a feeding trap tube, which is guided centrally through the separator ( US Pat. No. 4,606,506 . DE 195 28 338 C1 ).
  • this feed can be largely prevented by caking even with very moist and sticky feed material, such as raw coal, a clogging of the feed tube.
  • a sifter rotor must be used with a hollow shaft for receiving the task fallopian tube.
  • Such a classifier rotor is considerably more expensive compared to a conventional classifier drive design.
  • the task of the feed material takes place via steeply inclined feed chutes, which are arranged laterally on the classifier and do not extend into the center of the roller mill or grinding chamber (EP 1 239 966 B1 . US Pat. No. 4,597,537 ).
  • feed chutes which are arranged laterally on the classifier and do not extend into the center of the roller mill or grinding chamber.
  • the strong inclination of the feed chute prevents at the same time a discharge parabola for the raw coal into the center of the grinding bowl.
  • the sifter and the lateral task chute would have to be positioned considerably higher.
  • the feed material such as raw coal
  • Disadvantageous consequences are an uneven grinding roller load and a reduced running smoothness of the roller mill as well as a lower energy efficiency of the grinding process. Incomplete supply of the raw coal to the grinding rollers and comminution can also lead to deposits of coal dust and a fire hazard.
  • Out EP 0 294 609 A2 is a roller mill with two grinding rollers known, which is intended for a relatively small throughput and, for example, as a laboratory mill.
  • the desired simple and inexpensive construction relates to training and arrangement of the roller carrier and its storage.
  • the roller carrier crosses the mill housing above the Mahltellers diametrically and has a central part with a central through-opening for feed material, which is placed over a centrally arranged in a cover of the roller mill feed nozzle.
  • An alternative roller mill is provided with an air sifter and a semolina cone.
  • horizontally arranged tube screw conveyor ends in a region of the cone wall, so that supplied feed material along the cone wall can reach a cone opening and centered on the grinding table.
  • Out JP 2000 237 614 A is an air flow roller mill with an additional classifying air flow for varying the grain size distribution, which is supplied tangentially above the grinding rollers, but below the viewing space.
  • the variable particle size distribution also serves to discharge coarse material rejected in the classifier by means of a horizontal screw conveyor which runs directly below the semolina cone opening.
  • the feed to be crushed passes through a screw conveyor, which ends in a vertical discharge pipe of the semolina cone or in the area between the grinding rollers and the semolina cone, centrally on the grinding bowl.
  • JP 2000 312 832 A is a vertical mill with a sifter rotor, but shown without a semolina cone.
  • the feed material passes through a feed line and a horizontal screw conveyor, which ends between two grinding rollers, into the grinding chamber.
  • the screw conveyor is mounted on the side of the mill housing and with its opening does not reach into the mill center.
  • the invention has for its object to provide a roller mill, in particular a coal mill, which ensures a continuous, uniform and cost-effective task / supply of the feed material and a trouble-free, efficient grinding process.
  • the invention is based on a roller mill, in particular an air-flow roller mill for grinding raw coal, with a feed system which supplies the raw coal to the center of the roller mill, in particular into the center of the grinding bowl, which is advantageously provided with a defined distribution area , guaranteed.
  • a feed system which supplies the raw coal to the center of the roller mill, in particular into the center of the grinding bowl, which is advantageously provided with a defined distribution area , guaranteed.
  • the feed material in the center of the semolina cone which is located above the grinding chamber and below a classifier, discarded, so that the feed material passes together with the rejected by the sifter coarse material in the center of the grinding bowl and is evenly distributed to all grinding rollers.
  • the worm shaft of the worm feeder is connected at one end to a drive device and mounted at the other end in a storage.
  • the drive device and the bearing of the worm shaft are arranged outside the roller mill.
  • the storage of the worm shaft outside the roller mill or the grinding / sighting space largely prevents contamination by coal dust.
  • roller mill with a screw feeder consist in addition to a continuous, uniform and trouble-free feeding of the feed material into the center of the grinding bowl and a uniform distribution of the feed material together with rejected in the classifier coarse grain on the grinding bowl and under the grinding rollers in an energy saving for the milling process. Energy savings of up to 5% compared to the previously used task arrangements are possible. In addition, a trouble-free and reliable, continuous material task is ensured.
  • the screw feeder as a tube screw conveyor and to guide substantially horizontally through the roller mill and the semolina cone.
  • the drive device and the bearing of the worm shaft can be arranged on a support structure on the mill housing.
  • a seal between the rotating worm shaft and the mill housing can be carried out advantageously in a mechanical manner or by means of sealing gas.
  • the worm shaft is provided outside a conveying trough of the worm feeder with a protective tube which extends from a milling chamber-side end region of the worm feeder to close to the bearing of the worm shaft outside the rolling mill.
  • the drive device for example a motor with a gearbox, can be operated at a constant or controllable speed, for example by means of a frequency converter, be executed.
  • a mill outside end portion of the screw feeder is provided outside the roller mill with the laterally arranged drive means, while a Mahlraumscher end portion is arranged in the semolina cone of the roller mill.
  • the outer wall end region of the screw feeder is provided with a receiving opening, via which the feed material in the screw feeder and with the help of the worm gear in a forced conveyance to the center of the roller mill, which is determined by the longitudinal axis of the roller mill passes ,
  • the milling space-side end region of the screw feeder has an ejection opening, which is designed and dimensioned coaxially with the longitudinal axis of the roller mill for the central feed of the feed material.
  • Such a supply and uniform distribution of the feed material, preferably together with the rejected in the classifier coarse grain, allows an energetically extremely advantageous grinding process.
  • the uniform distribution of the feed material to be crushed also improves the smooth running of the roller mill and allows a better adjustment of the setting parameters for the grinding.
  • the worm gear, the conveyor trough and a cover or the tube screw conveyor from the outer end of the mill outside to the milling room side end range, while the worm shaft from the outside drive means, which is particularly close to the receiving opening, extends to the storage outside the roller mill at the opposite end ,
  • the screw feeder is connected via its receiving opening in the outer wall end region with a feed channel for the feed material.
  • This feed channel can expediently be arranged substantially vertically and have at the upper end a rotary valve which serves as an air seal.
  • the feed channel of the feed system may be formed in a simple construction as a closed pipe.
  • the feed material can then fall from the rotary feeder via the closed feed channel and the receiving opening in the screw conveyor or in the conveyor trough, to then transported by means of the worm gear to the trough-side ejection opening and dropping vertically down the grinding bowl centrally.
  • the roller mill 2 has a grinding bowl 4, which rotates about a longitudinal axis 20.
  • the grinding bowl 4 is provided with a grinding path 26 on which a grinding bed is formed from the feed material to be crushed (not shown).
  • a suspension system (not shown) force-loaded grinding rollers 6 roll off and crush the feed material 5, which is supplied by means of a feed system.
  • grinding roller 6 In the drawing figure, only one grinding roller 6 is shown schematically. In principle, two, three, four or more grinding rollers can be arranged.

  • the classifier 7 is provided with a rotor 30 which rotates about the longitudinal axis 20 and has sight strips 31. Concentrically around the sifter rotor 30, a Leiterielkranz 33 is arranged to form a viewing space 32.
  • the semolina cone 8 has on the bottom side a central cone opening 9, which allows a central supply of the coarse grain to the grinding bowl 4 or to a central distribution region 24 of the grinding bowl 4 and a uniform feed to the grinding rolls 6.
  • the central distribution region 24 is frusto-conical. Uniform distribution of the coarse grain and the feed material 5 supplied by means of the feed system is ensured by uniformly discharging the feed material 5 and the coarse grain via the conical distribution region 24 or displacement body and on the grinding bowl 4 under centrifugal force in the direction of the grinding path 26 and below the grinding rolls 6 reach.
