Definitions

  • the present invention relates to a method for improving the productivity of grinding plants, the optimum wear geometry of grinding plants being preserved by applying a protective layer, and thus the susceptibility to repair of the plants being reduced and their productivity being improved.
  • the comminution effect of grinding tools is particularly influenced by signs of wear.
  • the specific energy requirement during the grinding process changes depending on wear. The energy requirement runs through a so-called “bathtub curve", with the energy requirement initially decreasing, then transitioning into a constant phase and finally rising steeply as the wear of the grinding aggregates progresses.
  • grinding tools made of cast steel can be made more wear-resistant by build-up welding.
  • build-up welding a high-alloy material is applied to highly stressed components as surface protection.
  • the welding materials contain chromium and carbon, with other carbide-forming substances such as niobium, vanadium or others being used depending on the desired wear resistance.
  • the third group of materials includes the grinding parts made of compound casting. Two or more materials are constructively combined to form a composite material.
  • the grinding tools are preferably made of a metal matrix composite material, with ceramic shaped pieces being embedded in a ductile cast iron. In this way, particularly hard and wear-resistant grinding tools are obtained.
  • WO2016101952 discloses a method for forming a wear surface on a roller body and correspondingly a grinding roller comprising a grinding surface coated with a thin anti-wear layer.
  • the object of the present invention is to offer a method that makes it possible to increase the service life of grinding aggregates or grinding bodies beyond the level known from the prior art.
  • the task is solved by a method for improving the productivity of grinding plants, which initially includes the step of setting the optimal wear geometry of the grinding aggregates by conventional operation of the grinding plant.
  • the wear geometry is optimal when the specific energy requirement of the grinding plant reaches a minimum for a given throughput.
  • the achievement of the optimal wear geometry is controlled and determined by continuous measurement and recording of the energy requirement.
  • the optimal wear geometry is then preserved by applying a thin wear protection layer to the surface of the grinding aggregates or grinding bodies, in particular grinding rollers and grinding plates.
  • the thin anti-wear layer is preferably applied by build-up welding or laser cladding.
  • Hard metals or carbidic hard materials such as WC, CrC, TiC, VC, TaC and NbC, can be used as the material for the wear protection layer, with hard metals being applied in a preferred embodiment of the present invention, which are doped with appropriate carbide-forming substances depending on the desired wear resistance become.
  • the method according to the invention is particularly suitable for vertical roller grinding plants, the grinding aggregates or grinding media to be coated being grinding rollers and grinding plates.
  • the layer thickness of the applied anti-wear layer is preferably 1 to 5 mm.
  • the invention also relates to grinding bodies which have grinding surfaces coated on the surface with a thin anti-wear layer.
  • the grinding bodies have an optimal wear geometry, which is determined by continuous measurement and recording of the energy requirement during the grinding process and is defined as the geometry at which a minimum of the energy requirement is achieved for a given throughput.
  • the wear protection layer is a build-up welded layer.
  • a further advantageous embodiment of the present invention provides that the grinding bodies are parts of a vertical roller grinding system and the coated surfaces are the grinding surfaces of grinding rollers and grinding plates.
  • the layer thickness of the thin anti-wear layer is advantageously 1 to 5 mm.
  • the present invention is based on the finding and the idea that the grinding media or grinding aggregates in most known grinding processes eventually form an optimal wear geometry that is only made possible by the wear of the grinding media and that adjusts itself automatically after a certain period of operation of the grinding plant.
  • the energy requirement runs through what is known as a "bathtub curve", with the energy requirement initially decreasing, then transitioning into a constant phase and finally rising steeply as the grinding aggregates wear out.
  • the achievement of the optimal wear geometry can be read from the energy consumption.
  • the optimal wear geometry is reached when the energy consumption is at a minimum with a constant throughput. This condition, in which the product quality also remains at a constant level, corresponds to the optimum for the grinding process.
  • the present invention is based on the idea of preserving the ideal state, in which the grinding media have their optimum wear geometry, and thus improving the productivity (yield, costs and quality) of the product to be ground. Since this state is reflected in the achievement of a minimum of the energy requirement, the optimal point in time for conservation of the corresponding geometry can be determined in a simple manner by continuous measurement and recording of the energy requirement.
  • a thin anti-wear layer is applied at this time to the part of the surface of the grinding aggregates or grinding media that is susceptible to wear, so that the geometry of the grinding media is not changed, while the wear resistance of the surface is increased and the geometry is thereby preserved. With continued operation of the plant, the geometry will now change less quickly in comparison to a geometry that has not been conserved, so that the ideal state is retained for longer and the grinding plant can be operated over a longer period of time without additional downtime.
  • the invention is to be explained in more detail below using a numerical example for a grinding plant for cement. According to conservative estimates, the measures described above should improve the availability of the grinding plant by more than 5%, which corresponds to a productivity increase of 5%. With a production of 200 t/h, this corresponds to an additional production of 86,400 t/a, which would correspond to an additional income of 1,036,800 € with a realistic profit of 12 €/t. At the same time, with a typical energy requirement of 28 kWh/t, continuous operation with optimal wear geometry would save an estimated at least 3% in energy costs, which corresponds to energy costs of approx. 0.15 €/kWh for an annual production of 1.5 million tons (90% utilization was calculated ) would correspond to €189,000.
  • the figure 1 is a sectional view of a section of a vertical roller grinding plant, such as that used in the cement industry.
  • a stationary, rotatable cylindrical grinding roller 1 is resiliently pressed against a rotary driven grinding table or grinding track 4, the grinding track 4 being reinforced with grinding plates 2 in the area against which the grinding rollers 1 are pressed.
  • the grinding aggregates or grinding media are in their original state and have a smooth, intact profile 5, 6.
  • the figure 2 shows the same arrangement as figure 1 after prolonged grinding operation, with the grinding rollers 1 and also the grinding plates 2 now showing their typical wear profiles 7, 8.
  • FIG 3 a section of a grinding roller 1 can be seen in a sectional view, with the grinding roller 1 having reached its optimal wear profile 7 .
  • the original profile 5 is drawn in dashed lines in this representation.
  • FIG 4 finally shows in the same representation as figure 3 the grinding roller 1, whose optimal wear profile 7 is now preserved with a thin wear protection layer 9, which is shown in dashed lines in the present case.
  • the grinding plates 2 also have an optimal wear profile, which is preserved in the same way with a thin wear protection layer.
  • the drawings described above are intended to be illustrative only and not limiting. That's how it can be The principle of the idea according to the invention can be applied to any other grinding plant in which an optimal wear geometry is also established during operation on its wearing parts. Also, the formation of the wear protection layer is not limited to build-up welding, but can be realized by any other known technique, it only having to be ensured that the right point in time for the preservation of the optimal wear geometry is selected in order to exploit the optimum of the advantages of the present invention .
  • the present invention can advantageously also be combined with other known methods for increasing the wear resistance of grinding aggregates or for safeguarding production. If, for example, as in the DE 203 21 584 U1 described, grinding rollers can be swiveled out during operation of the plant virtually without stopping production, the optimal wear profiles on the surfaces of the grinding rollers can be preserved without resulting in a loss of production, whereby the repair interval for the plant is then extended at the same time.
