Definitions

  • the invention relates to a discharge wall for discharging the ground material from a tube mill, the at the end of the regrind the discharge wall built in is double-walled with a slot permeable to the ground material provided front wall, with a spaced from the front wall closed back wall, with one both walls of the discharge wall connecting central mill gas flue and with over it Scope of distributed grist outlet openings.
  • a built in a tube mill between two grinding chambers double-walled transfer wall composed of segments, which can be regulated is from a brochure from Magotteaux S.A., Vaux-S-Chchangingmont / Belgium.
  • the invention is therefore based on the object to discharge the To create regrind from a tube mill, a discharge wall can be regulated in such a way that there is no great effort involved in assembly targeted with changing grinding properties of the respective regrind Influence on the regrind loading in the grinding chambers and on the necessary regrind residence time can be taken.
  • the circumference of the regrind outlet openings is adjustable Metering slide for steplessly changing the opening cross-sections on.
  • the metering slide can always be used translatory shift direction be formed.
  • the feature of the invention are those around the radially inner circumference grist discharge openings distributed around the discharge wall crescent-shaped, and the metering slide are then as Rotary slide valve, also with a crescent-shaped configuration, so that depending on the rotary position of the rotary valve a more or less large part of the regrind outlet opening can be covered is. In this way, depending on the rotational position of the Rotary valve, which causes a certain back pressure effect on the regrind specifically influences the dwell time of the material to be ground in the grinding chamber can be taken.
  • the adjustable metering slide according to the invention in particular the rotatable rotary valve allow one Control intervention not only on the amount of regrind, but also on the Process gas volume in the tube mill, and the rotary vane can so that the path for the mill gas or process gas remains open.
  • the grist outlet openings with their rotary valves can be in the closed rear wall of the double-walled discharge wall distributed around the circumference of the central mill gas exhaust duct his.
  • the grist outlet openings with their rotary valves can also in the central mill gas duct itself, d. H. be arranged around the radially inner circumference of the discharge wall, which can be cylindrical or conical.
  • the regrind outlet openings each over at least two adjacent segments the discharge wall composed of radial segments, so that the radially inner circumference of the discharge wall takes the form of a polygon.
  • the rotary valves are outside the discharge wall segments arranged at the grist outlet openings and on this Way wear protected.
  • Fig. 1 shows a section of the regrind end of a tube mill with the tube mill jacket 10 and with a grinding chamber, the with grinding media 11, such as. B. steel balls, and with the in between lying regrind is filled.
  • the end of the regrind is a double-walled in the tube mill jacket 10 radial and usually cast iron segment chambers composite discharge wall installed with a for the ground material permeable, provided with slot openings 12 Front wall 13 and with a spaced apart from the front wall closed rear wall 14. Both walls of the discharge wall are standing through a central, slightly tapered discharge duct 15 with each other, through which the bulk of the Mill gas 16, such as. B. air, through a central sieve 17 is subtracted.
  • the Grist outlet openings 19 are approximately crescent-shaped and they are each rotatable about a central pin 20
  • Rotary slide valve 21 also with an approximately crescent-shaped configuration depending on the rotary position more or less extensively coverable.
  • the regrind outlet openings in the discharge wall variant of FIG. 1 19 with their rotary valves 21 in the rear wall 14 of the Discharge wall around the circumference of the central mill gas exhaust duct 15 are distributed, are in the discharge wall variant 2, the regrind outlet openings 19 with their rotary valves 21 itself arranged in the central mill gas exhaust duct 15, and although in the illustrative embodiment in a cylindrical Section of the same.
  • the regrind emerges from the regrind outlet openings 19 radially inwards and is then immediately from Mill gas stream 16 discharged from the tube mill.
  • the discharge wall are the rotary valve 21 after removal the central sieve 17 also easily accessible for the purpose of regulation. to Limitation of the number of rotary valves 21 and grist outlet openings 19, these each extend over at least two neighboring ones Segments of the composed of the radial segments Discharge wall.
