Description

Technical Field

[0001] The utility model relates to the technical field of single spiral classifiers, in particular to a high weir type single spiral classifier. Background Art

[0002] High weir single spiral classifier is suitable for separating ore sand in a closed-loop process with a ball mill in a ore dressing plant, or for classifying ore sand and fine mud in a gravity ore dressing plant, for particle size classification of slurry in metal ore dressing process, and for desludging and dehydration in ore washing operations. It is also suitable for wet separation of heavy metals in slag. The classifier has the characteristics of simple structure, reliable operation and convenient operation. The classifier is a grading equipment that uses the principle that the solid particles have different sizes and specific gravities, and thus have different settling speeds in the liquid. Fine ore particles float in the water and overflow, and coarse ore particles sink to the bottom of the trough and are pushed to the upper part by the spiral to be discharged for mechanical classification. It can filter the crushed slag, and then use the spiral to screw the coarse material into the mill feed port, and discharge the filtered fine material from the overflow pipe.

[0003] At present, when the high weir single spiral classifier is actually used, the spiral blades and the rotating shaft are connected and fixed by multiple fixing bolts, which requires tightening and removing more fixing bolts when installing and disassembling the spiral blades. The workload of installation and disassembly is large, which in turn makes the installation and disassembly time of the spiral blades longer and the efficiency of installation and disassembly is low.
