Definitions

  • the invention relates to a roller mill with the features according to the preamble of claim 1.
  • a roller mill In the heavy clay industry, roll mills are used for processing clays.
  • a roller mill comprises two rollers which are rotatably mounted. The two rollers are arranged at a distance from one another, so that a gap is formed between them.
  • the two rollers are driven in opposite directions to rotational movements.
  • the coarse raw material In the gap between the rolls, the coarse raw material is ground to a grain size of up to 0.5 mm. Due to the resulting wear of the surfaces of the rollers they must be smoothly pulled regularly. This reduces the diameter of a roller continuously.
  • the width of the gap between the two rolls is of crucial importance.
  • the rocker has two opposite in the direction perpendicular to the pivot axis of the rocker arms. At the end remote from the pivot axis of the first arm a stop element of the first arm is arranged. At the end remote from the pivot axis of the second boom attacks the overload protection.
  • the overload protection comprises a biased by a stop spring element.
  • the spring element acts on the nut element in the longitudinal direction. Due to the interplay of the spring element of the overload protection and the nut element of the adjusting element, the first roller of the roller mill can easily avoid overloading and increase the gap between the first roller and the second roller.
  • a safety shoulder 34 of the operating element 30 has a fifth distance a5 measured in the longitudinal direction 100 relative to the overload shoulder 61.
  • the safety shoulder 34 faces away from the connecting element 34.
  • the safety shoulder 34 has a distance to the axis 101, which is at least as large as the distance of the pressure element 8 to the axis 101.
  • the fifth distance a5 is smaller than the third distance a3.
  • the fifth distance a5 is smaller than the fourth distance a4.
