Definitions

  • the invention relates to a pan mill for the preparation of ceramic materials, in particular brick clay, according to the preamble of claim 1.
  • a pan mill is known from DE 36 40 081 A1.
  • the regrind is subjected to positive guidance in such a way that it has to pass through a spiral path on the grinding track surface from the inside out and is thereby subjected to a number of rollover processes.
  • This ensures a comparatively long dwell time of the ground material with several roll-over processes by the inner and outer rotor, even with large throughput quantities per unit of time.
  • It has turned out to be disadvantageous, however, that the grinding track surface wears out comparatively quickly and therefore has to be replaced frequently.
  • This wear is uneven, ie the overlap area of the grinding tracks of the inner and outer runner wears out particularly quickly, with the result that the grinding track surface becomes uneven; an uneven grinding track surface not only leads to an uneven grinding process but also furthermore, if the runners roll directly on the grinding track surface, which can happen before or after or when the supply of grinding material is interrupted, there is a risk of damage to the rotor surfaces, their suspension and / or their drive. Furthermore, the rotor surfaces on an uneven grinding track surface also wear unevenly, which further deteriorates the grinding process. If only the worn grinding track surface is changed, the unevenly worn runners do not roll over the entire surface but only with edge areas on the grinding track surface, which leads to increased wear.
  • the object of the present invention is therefore to improve the known pan mill of the type described so that the wear of the grinding track surface is as small as possible and, above all, as uniform as possible. This object is achieved by the characterizing features of patent claim 1.
  • the pan mill rests on a construction consisting of a foundation 11 carrying a central column 10 and a supporting base 13 lying at a distance above it and held by columns 12, on which rests an annular grating 14 which in its center is supported by the supporting base 13 or the center column 10 and on its outer circumference is supported by the columns 12.
  • Center column 10 and grate 14 are penetrated by a vertical vertical shaft 15 which is driven at its lower end by a gear 16 by a motor 16 and whose upper end is located above grate 14, namely within a protruding vertically upward from the outer circumference of grate 14 Side wall 17.
  • two runners run around, namely an inner runner 18 and an outer runner 19, which are mounted vertically displaceably via transverse arms on the vertical shaft 15 and are driven by the latter .
  • two crushing surface arrangements are fastened to the vertical shaft 15, namely a crushing surface 20 trailing the inner rotor 18 in its circumferential direction and a crushing surface 21 trailing the outer rotor 19.
  • a channel-shaped material feed 23 On the free upper end of the vertical shaft 15 there is a channel-shaped material feed 23, the upper one of which End is fed via a conveyor, not shown, such as a belt conveyor, with the material to be shredded, while the lower end 23a is located at such a location above the material web surface is that the material is released directly - in the direction of rotation of the rotor - in front of the inner rotor 18 onto the grinding track surface.
  • the material feed 23 is rigidly connected to the vertical shaft 15 so that it rotates with it. It is important that the grate 14 is divided into an inner grinding track surface 14a without openings and an outer grinding track surface 14b with openings 24, the inner grinding track surface 14a being overrun by the inner rotor 18 and the outer grinding track surface 14b by the outer rotor 19.
  • the two runners 18, 19 are arranged diagonally to one another, as can be seen in FIG. 1; the representation of Fig. 2 with both runners on the same radius does not correspond to the actual design and has only been chosen for better understanding.
  • the two grinding tracks of the rotors 18 and 19 do not overlap, but rather adjoin one another with no or with a minimal gap.
  • the distance a of the vertical outer surface of the inner runner 18 from the central runner axis is equal to or slightly less than the distance b of the inner vertical surface of the outer runner 19 from the central runner axis.
  • a ⁇ b The inner grinding track surface 14a is thus exclusively overrun by the inner rotor 18, the outer grinding track surface 14b exclusively by the outer rotor 19.
  • the wear of the inner grinding surface 14a and that of the outer grinding surface 14b and the rotor surfaces 18 and 19 is therefore extremely uniform.
  • the wear of the two grinding track surfaces 14a, 14b over the rotor surfaces 18, 19 with one another is not uniform, that is to say the outer grinding track surface 14b will wear out faster, specifically because the outer grinding track surface 14b is provided with openings 24.
  • the rotor surfaces 18 and 19 are used also different because they have different roll areas and different roll behavior.
  • the fact that the two grinding track surfaces 14a, 14b and rotor surfaces 18 and 19 are separate components results in no difficulties from the uneven wear; the outer grinding track surface 14b is replaced more frequently than the inner grinding track surface 14a, and also the runners 18 and 19.
  • the center column 10 has a considerable diameter, such that it grinds the grating track grate 14 or the supporting base 13 e.g. supported approximately in the center of the inner rotor 18.
  • the radius of the center column 10 is equal to or greater than the radius of the center point of the inner rotor 18, in each case with respect to the center axis of the pan mill.
  • the support base 13 is dimensioned so that the outer grinding surface 14a is supported with its inner edge on the outer edge of the support base 13; this ensures that the grating track grate 14 manages with a comparatively simple and light support, namely the light and comparatively small supporting floor 13 and the outer columns 12.
