Definitions

  • the invention relates to a single roller crusher for crushing solids with a rotatable mounted, rotatably driven roller and with a swing arm assigned to it as crushing tools, wherein at least the surface of the roller facing the rocker is profiled, wherein the profile, which is formed by ribs and grooves arranged between them, at least is inclined in regions to the direction of the relative movement between roller and rocker.
  • the shredded material has an elongated grain shape that is less suitable than in many applications an approximately cubic shape of the grain. i.e. a shape of the grain that is not particularly pronounced Has length extension in one direction.
  • a roller mill is known from EP 0 563 564 A2.
  • the well-known roller mill for shredding von brittle regrind has two counter-rotating, high pressure against each other pressed grinding rollers, each with a surface profile roller shell have wear-resistant chilled cast iron. So that the rollers have a particularly good pulling capacity and have a high wear resistance, are profiles on the surface of the roll shell applied in the form of welding beads made of wear-resistant build-up welding material.
  • the invention has for its object a particularly suitable for fine grinding Single-roll crusher of the type mentioned above. with the under good use of the Energy mostly crushed material is obtained with a grain shape that is approximately cubic or is spherical, that is, it does not have a length extension that is particularly pronounced in one direction.
  • the profiling of the roller and, if necessary, the the rocker arm is formed by a body made of hard material and the roller is made of there are several disks arranged side by side in the axial direction, with each disk on has circumferential ribs and grooves to form the profile.
  • the desired effect is achieved because of the particularly structured Surface of at least the roller, which is one of the two tools causing the comminution is such an interaction that not only a movement of the shredded Solid grains are created perpendicular to the moving roller, but also a movement component occurs perpendicular to the direction of movement of the relative movement.
  • the movement component is in the single-roll crusher according to the invention by structuring (profiling) the surface the roller and preferably also one of the rocker. This movement component transverse to the direction of movement of the roller leads to the rolling movement of the grains in the crushing chamber and thus to round it off. This essentially turns the grain shape into Direction cubicity improved and thus the disadvantage of the above-mentioned known shredding device avoided.
  • the angle of the profiling to the direction of the relative movement between the roller and the Swing arms can be selected depending on the properties of the material to be shredded and under Taking into account the other operating conditions of the single roller crusher. It is preferred in the context of the invention that the profiling of the roller and / or that of Swing into sections opposite to the direction of relative movement is divided between roller and rocker. It can be provided that the profiling in the different sections with the direction of the relative movement between roller and Swing arm encloses equally large, but opposite angles. In certain applications an embodiment in which the profiling in the different sections has proven itself with the direction of the relative movement between roller and swing arm of different sizes and includes opposite angles.
  • the profiling of the roller and possibly that of the rocker can be transverse to Direction of the relative movement between roller and rocker seen zigzag or run serpentine.
  • Fig. 1 One especially intended for the fine grinding of minerals (rock) and as a single roller crusher designed crushing device is in the embodiment shown in Fig. 1 from a rotationally driven and rotatably driven roller 1 about an axis 3 and one Outer periphery of the roller 1 assigned rocker 2, for example, by a hydraulic drive is pivotally mounted in the frame of the shredding device and is firm or flexible (resilient) is loaded onto the roller 1.
  • ribs 5 are distributed over the circumference and between these grooves 6 provided.
  • the ribs 5 and the grooves 6 can be uniform on the roller 1 (over the circumference) be distributed.
  • the roller 1 is composed of several disks 4, Each of which carries a portion of the ribs 5 and the grooves 6 on its outer circumference.
  • the ribs 5 and the grooves 6 can also run so that they have areas in which they refer to the direction of the relative movement (arrow 10) between roller 1 and rocker arm 2 run in parallel.
  • the ribs 5 and the grooves 6 can also be serpentine run.
  • the tool bodies 11 inserted into the rocker arm 2 also bear those facing the roller 1
  • Effective surface structuring which consists of ribs or cutting 13 and in between arranged grooves 14 is composed.
  • the sections 15 and 16 in which the ribs 13 and the grooves 14 arranged between them each run parallel to one another, approximately like this wide, like the disks 4 from which the roller 1 is composed.
  • Ribs 14 can in the direction of the axis of rotation 3 of the roller 1, i.e. transverse to the direction of the relative movement (Arrow 10) between roller 1 and rocker 2 seen the same width as sections 7 and 8 of the ribs 5 on the roller 1.
  • the ribs 5 and the grooves 6 of the roller 1 are wider than that Ribs 13 and the grooves 14 on the rocker arm 2.
  • the ribs 13 and the grooves 14 can also be arranged unevenly distributed. Ribs 13 and the grooves 14 can also extend so that they have areas in which they for Relative movement between roller 1 and rocker 2 run parallel.
  • curved ribs 5 and 13 are also advantageous.
  • Applications can be an uneven distribution of the ribs 5 and grooves 6 on the roller 1 and / or the ribs 13 and the grooves 14 on the rocker 2 bring better results.
  • the ribs 5 and the ribs 13 are formed in that in the disks 4 of the roller 1 and in the rocker 2 or its tool body 11 strips made of hard material are used. There is the possibility of the different structural elements (i.e. the ribs 5 and 13 on the one hand and the Carrier material on the other hand) to form different materials, so that a self resharpening effect results.
  • the size of the angles ⁇ and ⁇ depends on the properties of the shredded material Material selected. For example, the diameter of the roller 1 from 300 to 800 mm and a thickness of the discs 4 of 50 mm angle ⁇ of the order of 10 to 40 °.
  • the angles ⁇ of the ribs 13 on the tool bodies 11 of the rocker arm 2 are, for example, in this case 40 to 80 °.
  • Angles are ⁇ 20 ° and ⁇ 70 °.
  • angle ⁇ of the order of magnitude from 10 to 40 ° are preferred, with the best at 15 to 30 ° in most cases Results are achieved.
  • the angles ⁇ can range from 40 to 80 °, preferably 50 to 70 ° be.
  • the height H1 of the ribs 5 of the roller 1 and the pitch T1, the height H2 of the ribs 13 and the Division T2 / T3 of the ribs 13 depends on the material to be cut and on the desired one Product grain belt selected.
  • flank angles ⁇ 1 and ⁇ 2 are also determined and can be based on these parameters for example, have values from -25 ° to + 25 °.
  • the flank angles ⁇ 1 and ⁇ 2 are however variable.
  • the gap "S" between the roller 1 and the rocker 2 is optionally adjustable because it is for the achievable product grain belt is crucial.
  • the invention can be represented as follows, for example:
  • the profiles formed by ribs 5, 13 are inclined to the direction (arrow 10) of the relative movement between roller 1 and rocker 2, so that in addition to the radial component of motion, the cubicity of the grain shape of the comminution products promoting axial movement component arises.
