Description

Technical Field

[0001] This utility model relates to the field of tailings filling sand bin technology, specifically a slurry making device for an ultrafine tailings filling sand bin. Background Technology

[0002] A tailings backfill bin is a device used for storing and processing tailings, primarily for tailings backfilling operations in the mining industry. Underground mining is mainly based on the backfilling mining method, which often uses bins for backfilling. Before backfilling, tailings are stored in the bin. During the tailings settling process, flocculants need to be added, as tailings are prone to sedimentation and caking, making it difficult to discharge. Therefore, tailings are slurryed before use to give them a certain degree of fluidity.

[0003] Currently, in existing tailings filling sand silos, slurry tends to adhere to the inner walls of the silos during use. If not cleaned promptly, this can lead to incomplete slurry discharge during the final discharge, requiring subsequent manual cleaning of the silo's inner walls. Therefore, a slurry preparation device for ultrafine tailings filling sand silos is needed. Utility Model Content
