Is the finer the ball mill grinding fineness the better

As an important mineral processing equipment for ore crushing and then grinding, grinding is its main task. So, when choosing ball mill equipment, is the finer the grinding fineness the better? The following is our understanding of the situation, to explain your doubts.

In actual production, some mineral processing plants in order to improve the magnetic separation efficiency of the magnetic separator, think that the finer the mill fineness is more convenient for magnetic separation, I do not know, this operation makes the mineral processing production line to take a lot of detours, not only reduces the magnetic separation recovery rate, but also increases the operating costs of the company.

In view of the many detours taken by many users, the relevant magnetic separation equipment experts suggest that the selection of ball mill for mineral processing plant should be based on the demand of mineral processing plant, according to the different characteristics of each nature of ore to formulate the grinding fineness requirements, and then according to the specific needs to choose the appropriate ball mill model.

Despite such a detailed statement, many users still cannot choose the right equipment, which is because the mineral processing plant does not have a clear ore grinding fineness demand. Because many grinding finenesses are concluded in countless mineral processing tests, for this situation, experts suggest that in the purchase of ball mill equipment can make the mineral processing plant materials and target finished products to tell the ball mill manufacturer, ask them to help reference more securely.

Experts point out that in the process of ball mill grinding, if the grinding products are too coarse, it will form the selected concentrate grade and recovery rate are low, too fine will output many difficult to select another microfine particles, present "over crushing" appearance. So no matter too coarse and too fine are not, only suitable grinding fineness is to achieve the necessary conditions for the separation of useful minerals and vein minerals. However, after heavy testing and practical operation we found that even if the ore is ground to the finest, the recovery index is not high. Experts concluded that the finer the grinding fineness is, the better the traditional concept is wrong.

In the production process, there are many traditional "self-righteous" ideas that lead to mistakes in the production process, and these "theories" without scientific verification may lead to safety accidents.
