Definitions

  • the invention relates to a Kreislaufmahlstrom for crushing regrind, comprising at least one high-pressure roller press, at least one device for prospecting of fines from the circulating millbase, and at least two devices for conveying the circulating ground material.
  • this Kreislaufmahlstrom is located on a ship.
  • High-pressure roller presses for the comminution of regrind were first described by Schönert et al. in the German published patent application DE 2708053 A1 disclosed. High-pressure roller presses grind millbase between two counter-rotating rollers, which show little or no slippage, by pulling the millbase into a narrow nip between the two rolls and treating them exclusively by pressure.
  • the ground material passes through more than one passage of the high-pressure roller press, wherein from the circulating ground material is always the fine-grained to powdery ground material is selected by a suitable device for prospecting the fine material.
  • the still insufficiently crushed grits are recycled.
  • the grits are recirculated until they are shredded to such an extent that they too leave the Kreislaufmahlstrom as a fine-grained to pulverulent regrind.
  • a Kreislaufmahlstrom consists essentially of three main trades.
  • a first item is the mill, here in the form of a high-pressure roller press.
  • a second trade is a device for the prospecting of fines and that third essential trade is a device for conveying the ground material between the mill and the device for conveying the circulating ground material.
  • the at least one high-pressure roller press is spatially removed and disposed approximately at the same height to the at least one device for prospecting of fines from the circulating ground material, wherein the at least two devices for conveying the in-circuit Ground meal cross from the side approximately centrally, the spatial distance is at least five to twenty times the width or length of the high-pressure roller press.
  • the Kreislaufmahlstrom invention moves away from the usual structure by a spatial distance of the mill, here the high-pressure roller press, the separator device.
  • the high pressure roller press and the sifter may be constructed at spaced apart locations so that a necessary foundation for the high pressure roller press alone and for the sizer device alone can be built.
  • a particularly solid foundation is to create only with great effort, for example, because a pile foundation for fixing a foundation for a known Kreislaufmahlstrom is necessary
  • the structure of the invention has the advantage that particularly solid foundations are dispensable.
  • High-pressure roller press is built in a self-supporting machine frame, then it is even acceptable if the high-pressure roller press vibrates slightly on the subsoil or moves slightly through a mitschwingendes soil. It is not to be feared that the dynamic loading of the high-pressure roller press in operation jeopardizes the construction of the entire Kreislaufmahlstrom.
  • the two devices for conveying the circulating ground material have a pitch of 10% to 30%, preferably of about 15% to 25%.
  • the comparatively low pitch can be made of simply constructed conveyor belts, which have no cups, drivers or blades.
  • conveyor belts with blades or with entrainment wet grinding stock can solidify, so that the transport capacity of the conveyor decreases with increasing energy consumption.
  • bucket elevators and conveyor belts with carriers are more maintenance-intensive, which can be a great advantage especially when used in remote areas without good infrastructure.
  • a movable device for Mahlgutholzgabe which optionally gives up fresh material on one of the at least two devices for conveying the circulating ground material.
  • the structure of Kreislaufmahlstrom according to this embodiment of the invention allows a quick change of the freshly abandoned regrind or the properties of the freshly abandoned regrind.
  • moist millbase is first dried in the classifying device by hot air before the first passage of the high-pressure roller press. In this case, the fresh ground material is placed on the conveyor, which leads to the sifter.
  • the freshly abandoned grinding stock should first pass the high-pressure roller press first, if
  • the humidity of the fresh ground material is so high that it even supports the grinding process, for example because vibrations of the high-pressure roller press are avoided.
  • Other regrinds that tend to clump together in the wet state are first fed to the high-pressure roller press, where the moist millbase is mixed with already pre-dried millbase and therefore the lumpiness is reduced.
  • the reasons for abandoning the ground stock either initially on the classifying device or first on the high-pressure roller press are varied and can be decided on a case-by-case basis by the person skilled in the art.
  • the arrangement of the Mahlgutholzgabe at the intersection of the at least two conveyors thus offers the advantage of rapid configuration change the Kreislaufmahlstrom.
  • the at least one device for prospecting of fine material from the circulating grinding material has at least one V-shaped cascade classifier, wherein the V-shaped cascade classifier obliquely or even transversely to the transport direction of the at least two devices for conveying the arranged in the circulation regrind is arranged.
  • the cascade classifier used in the Kreislaufmahlstrom performs various functions.
  • a first function is the comminution of resulting in the high-pressure treatment of the ground material flakes.
  • the scabs fall as if on a staircase several times on jalousieeartig arranged sheets, the scabs break up and split in the updraft of cascade viewers in fines and in recirculated grits.
  • a second function of the V-shaped cascade classifier is to separate the fines from the reclaimed seeds to remove the fines from the milling process.
  • the orientation is advantageous obliquely or transversely to the transport direction of the at least two conveying device, because thereby arranging the crossing conveyors spatially let them not collide at the crossroads.
  • the vertical centers of inlet and outlet of the at least one high-pressure roller press and the at least one device for prospecting of fine material from the circulating millbase are located approximately at the same height.
  • This orientation inlet and outlet which is not necessarily associated with the ideal orientation in terms of the lowest possible lifting work for the recirculating in the circulation, allows the arrangement on a ship.
  • the Kreislaufmahlstrom invention is constructed on a ship or on a floating pontoon. It may be economically advantageous to transport the grinding stock to be comminuted from its mining site, from the mine or quarry to a mooring of the ship or pontoon with Kreislaufmahlstrom to crush there on the ship or pontoon the ground material and the ground good back there transport, where it is further processed.
  • the grinding plant built on a ship allows mobile use of the Kreislaufmahlstrom.
  • the above-described alignment of the at least one high-pressure roller press and the at least one device for prospecting of fine material allows a careful trim of the ship as a foundation for Kreislaufmahlstrom.
  • the height of the center of gravity of the individual units is less important for the operation of Kreislaufmahlstrom as for the transport of Kreislaufmahlstrom at sea.
  • the construction according to the invention also makes it possible for the weight of the Kreislaufmahlstrom is distributed on the ship over the length of the ship.
  • the at least one high-pressure roller press is arranged in the aft third or at the border between eighth third and middle third of the ship's length of the ship, where a ship is built due to the location of the heavy ship engine usually stable and where ships are usually designed to rotate in a pounding or yawing motion in the sea state around a point that lies on the border between the aft third of the ship's length and the middle third of the ship's length.
  • the low linear accelerations are advantageous for the use of the usually very heavy-duty high-pressure roller press on a ship, since the anchorages of the high-pressure roller press in the ship are not too heavily loaded in rough seas.
  • the at least one device for the prospect of fine material from the circulating ground material in the front third of the ship is arranged.
  • This preferred construction allows the storage of ground regrind or fresh material between the at least one high-pressure roller press in the aft third of the ship's length and the at least one device for prospecting of fine material from the circulating ground material in the front third of the ship's length, so that even during operation the Kreislaufmahlstrom the ship or the pontoon is evenly loaded.
  • the focal points of at least one high-pressure roller press and the at least one device for the prospect of fines from the recirculating material in the circulation are in the ship's centerline.
  • the ship's centerline orientation allows the vessel to perform a sway in the swell without the ship or pontoon showing a dangerous inclination that causes the ship to steer straight ahead.
  • the Kreislaufmahlstrom invention In a particular embodiment of the Kreislaufmahlstrom invention is provided that at least two devices for conveying the circulating ground material are enclosed by a housing.
  • the enclosure allows the transport of hot or heated regrind, so that the heat of drying is not lost too quickly to the environment. Furthermore, will the regrind is not unnecessarily wet when transported in the rain.
  • the housing prevents the washing away of the fine, dusty ground material during transport from the high-pressure roller press to the classifier.
  • FIG. 1 is a Kreislaufmahlstrom 1 invention outlined in a view from the side with its three major trades.
  • the essential trades are a high-pressure roller press 2, a device for screening 3 of fine material from the circulating material to be ground 4 and two devices for conveying 5.1 and 5.2 of the circulating ground material 4.
  • the high-pressure roller press 2 is spaced from the device 3 for screening of fines from the circulating regrind 4.
  • the connection between the two trades is over in FIG. 1 sketched two devices for conveying 5.1 and 5.2 given. These transport the material to be ground 4 each uphill from one product to another in each case, so that the cycle of the material to be ground between high-pressure roller press 2 and device for sifting 3 is formed.
  • Fine material to be ground 4 is removed by the device for sifting 3 from the circulation and fresh, coarse material to be ground in the Kreislaufmahlstrom 1 by posting on the high-pressure roller press 3, by posting on the device for sifting 3 and / or by task on the Devices for conveying 5.1 and 5.2 inserted into the circuit.
  • the Kreislaufmahlstrom 1 is shown in a view from above in a first configuration 1.1.
  • this configuration 1.1 the conveying devices 5.1 and 5.2 are arranged in the form of a right-angled triangle.
  • the millbase passes through the high-pressure roller press in the vertical direction. Therefore, the conveying devices 5.1 and 5.2 overlap at this location.
  • the sifting device 3 passes through the material to be ground not only in the vertical but also in the horizontal direction component.
  • the device for conveying 5.1 is tilted.
  • the line of symmetry of the high pressure roller press 2 does not coincide with the distance line 6 between the two high pressure roller press 2 and sizing devices 3.
  • This configuration 1.1 when mounted on aligned foundations, could cause unnecessary difficulties in attachment to the respective one Create foundation.
  • FIG. 3 illustrated configuration 1.2 provided that the Kreislaufmahlstrom 1 seen from above, is arranged symmetrically, so that the two devices for conveying 5.1 and 5.2 form an isosceles triangle.
  • This configuration 1.2 facilitates the construction on usually oriented foundations.
  • FIG. 4 is outlined how the Kreislaufmahlstrom 1 is arranged in a hull 7.
  • the hull 7 is drawn with its silhouette from the side.
  • the location of the heavy duty high-pressure roller press 2 is ideally located approximately at the border between the eighth third and the middle third of the length of the ship. However, the ideal location varies with the actual hull design. Many ships are able to pick up heavy loads at the specified location. Due to the inventive spacing of the high-pressure roller press 2 and the device for sifting 3, an ideal weight distribution of Kreislaufmahlstrom in the hull 7 is possible.
  • the high-pressure roller press 2 and the sizing device 3 can be ground material, fine material, but it is also possible to accommodate additional auxiliary equipment, such as blowers, dust collectors and silos.
  • FIG. 5 the configuration is 1.1 off FIG. 2 portrayed in the hull with a view from above. Due to the asymmetric structure, it is necessary to arrange the heavy duty high-pressure roller press 2 and the sighting device 3 angled so that their center of gravity is located in the ship's centerline. In the oblique arrangement, depending on the type of hull, difficulties may arise in the stable arrangement within the hull 7.
  • FIG. 6 In order to achieve a symmetrical arrangement in the hull for ideal weight distribution, is in FIG. 6 the symmetrical arrangement according to configuration 1.2 FIG. 3 represented in a ship's hull 7.
  • the high-pressure roller press 2 is aligned in the longitudinal direction of the hull 7 with its own longitudinal direction of the high-pressure roller press 2.
  • the sighting device 3 is oriented transversely to the longitudinal direction of the ship's hull 7 in order to avoid a collision of the conveying devices 5.1 and 5.2 in the space.
  • the conveying devices 5.1 and 5.2 are preferably enclosed by an enclosure 9.
  • FIG. 7 is shown a particular embodiment of the Kreislaufmahlstrom invention. Due to the side view, this differs in FIG. 7 sketch not shown in the FIG. 1 sketch shown. However, in this Kreislaufmahlstrom 10 two devices for sifting 3 and 3.1, which are exactly behind each other in this view. The granules conveyed back to the high-pressure roller press 2 in the circuit are correspondingly conveyed via two conveying devices, which are shown in this sketch in FIG FIG. 7 are also shown exactly one behind the other, fed back to the high-pressure roller press 2.
  • FIG. 8 is the configuration of Kreislaufmahlstrom 10 off FIG. 7 shown in a view from above.
  • For Kreislaufmahlanlagen 10 with very high throughput is provided that there are two devices for sifting 3 and 3.1, in which the grits are jointly conveyed from a high-pressure roller press 2 via a device for conveying 5.2.
