Definitions

  • the invention relates to a partition for a tube mill according to the preamble of claim 1 and a grinding method according to the preamble of claim 14.
  • a generic partition is from the German utility model 203 12 219.4 known.
  • a separate material from a central air flow material transport from a first grinding chamber into a next grinding chamber is defined in the region of a central air passage opening trained annular channel arranged.
  • the grinding material lifted by radially arranged, in particular bent or curved lifting blades passes through inlet openings, which are arranged coaxially to the air passage opening, in particular in an outer ring of the annular channel, into the annular channel and becomes essentially over those rear-side discharge openings, which are in a nearly horizontal position , discharged.
  • the known partition has four discharge openings, which are formed at a distance of about 90 ° in a rear wall of the circumferential annular channel.
  • deflecting elements are arranged in the annular channel, which are conical and cause a material discharge through those discharge openings, which are located approximately in a 9 and 3 o'clock position.
  • the rear wall of the annular channel is composed of circular ring segments which have different sized discharge openings and can be exchanged according to the respective requirements.
  • the known partition allows Mahlgutaustrag or -übertrag in a second grinding chamber largely without being affected by the central air flow.
  • the known partition does not meet the requirements in any case and is relatively expensive in terms of the regulation of Mahlgutaustrages or -übertrages.
  • the invention has for its object to provide a partition and a grinding process for tube mills, which ensure a strict separation of Mahlguthnes during transfer to a next grinding chamber with a relatively simple construction and cost-effective production of the partition, reduce wear at the beginning of this grinding chamber and increase the grinding performance, while ensuring efficient grinding and regulation of Mahlgutaustrages.
  • the object is achieved by a partition with an annular channel in the region of a central air passage opening, in which guide blades for transport are arranged spirally arranged in the annular channel grinding material.
  • the entering through the respective inlet openings in the annular channel material or ground material is deflected by the guide blades and transported and reaches the discharge openings.
  • deflection which are arranged in the region of the outlet openings, the material to be ground is deflected and discharged through the rear discharge openings in the adjacent Mahlkammmer.
  • a basic idea of the partition wall according to the invention and of the grinding method according to the invention can be seen to selectively guide the entering material to be ground into the next grinding chamber by means of defined guide vanes within the annular channel in an adjustable material flow below the central air passage opening.
  • the ground material passes immediately behind the partition into the next grinding chamber, so that their entire grinding length can be used for an efficient milling process and at the same time less wear of the grinding balls and backwall plating takes place.
  • the guide vanes are arranged and formed in the annular channel that Mahlgut, which is lifted by lifting blades and inlet openings, which are approximately in a horizontal to vertical position, in particular between about 3 to 12 o'clock position, fed to the annular channel is passed on assigned guide blades and transported to the outlet openings, which are arranged offset by about 90 ° downstream of the inlet openings.
  • the discharge openings are formed annularly in a rear wall of the annular channel, which is preferably aligned with the downstream rear side of the partition wall.
  • the guide vanes are inclined and bent in the material conveying direction analogous to the lifting blades. It may be advantageous if the guide vanes have a same or lower bending radius compared to the lifting blades.
  • Each inlet opening is advantageously associated with a guide blade.
  • the guide vanes lie in front of the inlet opening on an outer ring of the annular channel, so that the e.g. Material which has been lifted by way of a long and short lifting blade is first deflected from the back of this guide blade and then transported on the following guide blade and preferably flow controlled up to the outlet opening cooperating with this guide blade.
  • each long and upstream short lifting blade are each an inlet opening, a guide blade with a deflecting element and an outlet opening, and preferably associated with a regulating device for the Mahlgut knockl.
  • the dividing wall has eight long and short lifting blades as well as eight inlet openings and the same number of guide blades, deflecting elements and outlet openings as well as regulating devices.
  • the regulation of the grinding material flow can in principle be effected by adjustable inlet openings, correspondingly dimensioned lifting and / or guide blades and / or discharge openings with an adjustable opening cross section.
  • a particularly advantageous regulation of the ground material flow provides slides which cooperate with the guide vanes and which are in particular radially aligned, extend through an inner ring of the annular channel and can be actuated from the central air passage opening.
  • the regulation of the ground material transported on a guide blade can take place in a first embodiment with the aid of a passage opening which is formed in the slide.
  • the passage opening may be formed as a gap between a lower edge of the slider and the guide surface of the guide blade.
  • the slide are adjustable and / or releasably secured in the annular channel, for example, held in slide holders.
  • An adjustable distance to the associated guide blade can be achieved with an adjusting device, for example a slot with a fastening element be, which can be operated advantageously from the central air passage opening.
  • a slider holder is disposed on the radially inner end of a guide blade.
  • a baffle and the rear discharge opening can each be positioned in front of the slide holder.
  • the slider holder advantageously extends in the radial direction as far as a first guide blade, while the slider itself extends as far as the following guide blade and is arranged at or at a distance from the guide surface of this second guide blade.
  • the slides are arranged diametrically to the flow direction of the ground material and have the width of the guide vanes or the annular channel.
  • a particularly simple adjustment of the slide can provide a backdrop-like support of the slider in the slide holder.
  • the baffles in the region of the discharge openings and the radially inner end region of the guide blades are advantageously wedge-shaped and are to form a wedge surface with the wedge tip on a front wall of the annular channel and with a contact surface on the respective slide holder.
  • the wedge surface then causes the deflection of the ground material in the direction of discharge and the discharge into the adjacent grinding chamber.
  • the discharge openings are designed in such a way that, in the case of the discharge openings positioned in the region between the 3 o and 6 o'clock positions, a tip is directed downwards so that the ground material can flow out at an early stage.
  • the discharge openings can be formed almost as a triangle.
  • a partition wall 2 which can be used as overflow or discharge wall. For a better overview those are attached to a front side 3 Trench wall panels and arranged on a back 4 rear wall panels not shown.
  • the partition wall 2 has an outer jacket 9 and an air passage opening 5 for a central air flow.
  • the air passage opening 5 is surrounded by a circumferential annular channel 10, wherein this is arranged in a rear region of the air passage opening 5 and an aligned with the back 4 rear wall 17, a parallel thereto arranged front wall 18 (see Fig. 4 ), an inner ring 21 (see also Fig. 2 to 5 ) and an outer ring 20.
  • the partition wall 2 rotates counterclockwise with the tube mill according to arrow A, and sufficiently comminuted material passes from a first grinding chamber (not shown) via the slot wall plates of the front 3 in the partition 2, is lifted by lifting blades 7, 8 and via inlet openings 11 in the outer ring 20 of the annular channel 10 axially fed to the annular channel 10.
