The selection of pumps for primary mill circuit applications is an extremely important part in the design or renovation of a mill. The pumps and associated equipment are large capital and relatively high-maintenance cost items. By using some basic selection criteria, both the initial capital cost and cost per ton of material being pumped can be reduced.
By careful analysis of the pump application data, the proper size pump can be selected. This can reduce the initial cost Proper sizing will also increase the life of the pump wear parts.

Ball mill is the key equipment for crushing materials after they are crushed. It is widely used in cement, silicate products, new building materials, beneficiation of black and non-ferrous metals, glass ceramics and other production industries, and dry or wet grinding of various ores and other grindable materials. The function of the ball mill circulating pump is to make the large particle minerals that do not meet the process requirements into slurry according to a certain proportion, and then return to the feed inlet of the ball mill through the ball mill circulating pump to complete ball milling again until the process requirements are met.

Type selection characteristics of ball mill recirculation pump:

1. As the medium conveyed by the ball mill recirculation pump has large particles, large wear and strong impact, high wear-resistant and impact resistant materials shall be considered for the overflow parts of the pump during model selection;

2. The ball mill recirculation pump are located below the mill, and the maintenance space is limited. Considering the service life, maintenance cycle and spare parts replacement cycle of ball mill recirculation pump, the pump with lower speed shall be selected during model selection, so as to prolong the service life and maintenance cycle of pump overflow parts and reduce maintenance times.
