The mining of broken ore bodies in domestic mines generally adopts a cemented filling mining method, so that the stability of ore vein and surrounding rock after mining is ensured, and the goaf is backfilled by preparing filling materials, so that the problem of goaf collapse is effectively avoided. When the filler is prepared, in order to reduce the cost of the filler, aggregate, rice stone, sand and 10% of filter cake with small granularity prepared by using slag stone are difficult to fully break up by traditional stirring equipment due to high mud content and high viscosity of the filter cake, so that small filter cake blocks remain in the filler slurry, and the consolidation strength of the filler is seriously affected. To solve this problem, an elastic high-speed activation mixer is used in the preparation of the filler slurry.
