Definitions

  • the present invention relates to a wet milling plant, in particular a plant for milling clays and hard materials, such as, for example, feldspar, to produce ceramic products.
  • discontinuous mills are used that comprise a rotating drum, inside which a milling chamber is defined.
  • the rotating drum is provided with an upper opening through which water, the materials to be milled and the milling bodies generally consisting of alumina spheres are delivered into the milling chamber, where the first load is made with spheres with a diameter varying between 30 mm and 60 mm.
  • the material to be milled varies in size, for example up to 15-20 cm for clays and up to 8 mm for hard materials.
  • the rotating drum is further provided with a lower opening from which the milled material in a water suspension, the so-called slip, is extracted at the end of the milling process.
  • the drum is rotated at a preset speed according to the diameter thereof and kept rotating at a constant speed for a certain number of hours until the desired degree of milling fineness is reached, i.e. the desired granulometry of the materials subjected to milling.
  • the drum stops automatically in the discharge position and through gravity the slip is discharged into proper storage tanks through the lower opening of the drum.
  • the complete milling cycle consists of a first step of kneading the clays and of a second refining step.
  • the step of crushing the hard materials does not begin because the latter, in the initial step, tend to be incorporated into the clays. Only in the second step of the cycle the milling and refining operation gradually start, which continues until the desired granulometry of the materials subjected to milling is obtained.
  • milling bodies consisting of alumina spheres and about 50% of the volume of the drum is loaded with the material to be milled and water.
  • the drum is lined internally with wear-resistant rubber or with allumina.
  • the milling bodies as already said, have variable dimensions, generally milling bodies are used of three different diameters varying from a minimum of 30 mm to a maximum of 60 mm. This is because in the initial kneading step heavy milling bodies of a large diameter are required and in the final refining step milling bodies of small diameter with a great number of contact points between them are required.
  • a single mill of large dimensions that has one or more internal chambers or a plurality of mills of reduced dimensions, each of which consists of a rotating drum inside which a milling chamber is defined.
  • the drum is provided with an axial inlet opening of large diameter, about 30 cm, through which there can be delivered into the milling chamber water, the materials to be milled via the mechanical devices and the supplementary milling bodies, and with an outlet opening of the same dimensions as the inlet opening, which is also axial, through which the material milled in water suspension, the so-called slip, can be discharged.
  • each mill a milling step is conducted, starting with a first coarse milling step, in which the clays are kneaded and pass into a water suspension, and subsequent steps in which the granulometry of the clays and of the other materials subjected to milling is progressively reduced to a desired value.
  • the slip can be transferred from one mill to the next by gravity, as disclosed, for example, in Italian patent application MO2008A000244.
  • the slip can be extracted from a mill and be poured into a storage tank from which, by a pump, it can be delivered to the next mill, as disclosed, for example, in Italian patent 1380382, or can be conveyed from one mill to the next by a conveying device, for example a screw feed device, arranged in a connecting conduit between the two mills, as disclosed, for example, in Italian patent 1361628.
  • a conveying device for example a screw feed device, arranged in a connecting conduit between the two mills, as disclosed, for example, in Italian patent 1361628.
  • milling bodies of the same dimensions can be used in each mill, inasmuch as each mill does not have to run the entire milling cycle of the materials but only one step of said cycle.
  • each mill is different from filling of the discontinuous mills, i.e. the milling chamber is filled to about 35% with the milling bodies.
  • the level of materials to be milled and of the water (slip) is about the same level as that of the milling bodies inasmuch as everything must be at a lower level than the axial inlet opening in order not to obstruct the supply of materials to be milled.
  • the bottoms of the mills are assembled with rubber heads provided with peripheral pockets that collect the slip in the bottom part to then discharge the slip during rotation towards the axial outlet hole.
  • Said pockets have calibrated holes that determine the flowrate of the mill.
  • the present invention proposes providing a milling plant for milling materials to produce ceramic products or to modify existing discontinuous mills by making a small hole in existing hubs and modifying the heads that permits a simple and easy transfer from one mill to the next of the water suspension of materials to be milled and optimises the energy efficiency of the plant.
  • the object of the present invention is achieved with a milling plant according to claim 1. Owing to the invention it is possible to transfer in a simple manner the material to be milled from one mill to the next without the position of one mill being constrained by the position of the other mills, so as to have maximum freedom in the spatial arrangement of the mills. Further, the plant according to the invention enables energy efficiency to be optimised, requiring, for the same productivity, lower energy consumption than that of prior art plants and also enabling the productivity thereof to be increased without increasing the number/volume of mills installed.
