Description

Ball mill of acid-resistant ball milling system Technical Field The utility model relates to the technical field of ball milling, in particular to a ball mill of an acid-resistant ball milling system. Background Ball milling systems are widely used for pulverizing and grinding materials in the industries of mineral processing, building materials, chemical industry and the like. However, the conventional ball milling system has the problems of high energy consumption, rapid abrasion of a lining plate, poor acid resistance and the like in the operation process, and particularly the problems are more remarkable when the ore containing the acid medium is treated. However, along with the process optimization discovery, the extraction liquid can be added into the ball mill to enable the acid to play a role in the ball milling stage, so that the ore is fully contacted with the acid while being ground, and the pre-leaching is realized, thereby reducing the consumption of sulfuric acid in the subsequent stirring leaching process, and effectively reducing the consumption of new water entering a production system, so as to relieve the expansion problem of a tailing pond. Based on such process considerations, there is a need for ball milling systems that meet the acid corrosion and wear resistance requirements.
