Ball milling system for calcium carbonate production

The invention relates to the field of calcium carbonate production. The invention discloses a ball milling system for calcium carbonate production, and aims to solve the problems that in the production process of calcium carbonate, when a ball mill is adopted to carry out ball milling treatment on the calcium carbonate, a proper amount of water needs to be matched to carry out ball milling motion, and operators need to repeatedly add the calcium carbonate in the operation. And the calcium carbonate on the steel balls needs to be washed by water after ball milling, so that the calcium carbonate ball milling efficiency is relatively low. According to the device, after calcium carbonate ball milling is finished and the sleeve is vertically arranged downwards through the ball milling loading, calcium carbonate and water can flow out of the filter holes from the two sets of half fan blade plates, discharging is achieved, the calcium carbonate is subjected to ball milling machining through the arrangement, the prob
