Definitions
- the invention relates to a Kreislaufmahlstrom for grinding coarse material to a fine material, in particular for the production of cement raw meal and / or cement from cement clinker with at least one roller press for crushing the coarse material, at least one classifier for separating the fine material generated during comminution of coarse material and at least a fine material separating device for separating the fine material from the classifier's classifying air.
- the object of the invention is to provide a Kreislaufmahltechnik available, which is scalable and can be maintained during operation.
- the Kreislaufmahlstrom invention is composed of more than one roller press with periphery, which together form an approximately circular sysmmetrisches Kreislaufmahlsystem in the plane perpendicular to Vertika- KHD Humboldt Wedag GmbH 19.1 1.2008
- individual roller press can be shut down during operation, so that the individual roller press can be maintained.
- Mahlgutholzgabe the corresponding roller press is shut down and thus runs the entire Kreislaufmahlstrom with reduced but not switched off capacity.
- the Kreislaufmahlstrom invention is easily scalable.
- the individual roller presses and their spare parts can be stored as standardized individual parts.
- the Kreislaufmahlstrom invention is suitable for replacing vertical roller mills, since their dimensions are comparable and due to a higher pressure in the nip compared to the pressure between the plate roller and the millstone of a vertical roller mill, the capacity is greater than that of a vertical roller mill, as the Umlaufbaum the grind is reduced by the higher nip pressure.
- a Kreislaufmahlstrom invention comprising four roller presses 1 a, 1 b, 1 c and 1 d, which are arranged symmetrically about a central riser 2 for the pneumatic conveyance of the circulating ground material.
- To be ground coarse material is in a central rod basket separator 3, which is located above the roller presses 1 a, 1 b, 1 c and 1 d centered on the riser 2, abandoned.
- the coarse material emerges from the side of the rod basket sifter 3 and, with tasks not shown here, is applied to the roll mills 1 a, 1 b, 1 c and 1 d. There, the coarse material is crushed and falls into the cascade classifier 4a and 4b below the roller presses 1 a, 1 b, 1 c and 1 d not shown here tasks.
- the coarse material is separated from the fines, wherein the coarse material down from the cascade classifiers 4a and 4b emerges and with a not shown lifting the vorg Batterye for another circulation coarse material is transported back to the rod basket sifter 3.
- the fine material is pneumatically transported through the central riser 2 also in the rod basket sifter 3 and from there into the four cyclones 5a, 5b, 5c and 5d.
- the fines are separated from the classifier air and from the cyclones 5a, 5b, 5c and 5d, the classifier air cleaned by the fines leaves the Kreislaufmahlstrom.
- the classifier air is transported away by the collector 6 almost dust-free.
- FIG. 2 shows an enlarged detail of the roller presses 1 a, 1 b, 1 c and 1 d from FIG.
- FIG. 4 shows an enlarged detail of the roller presses 100a, 100b, 100c, 100d, 100e, 100f, 100g and 100h from FIG.
