Grinding concentration directly affects the fluidity of the slurry in the cylinder and the ability to transport the ore particles, and also affects the role of grinding media. Therefore, a grinding operator should be good at mastering the grinding concentration. Production practice has proved that the most suitable grinding concentration is between 60 and 83%. When rough grinding, the grinding concentration is slightly larger, generally controlled between 75-83%; when fine grinding, the grinding concentration can be lower, about 65-75%. Ores with different specific gravity may have different grinding concentrations. The ore concentration can be controlled to be higher than that of the ore, and the ore concentration should be smaller. In short, a grinding operator can only master the concentration of the slurry if he is diligent in operating the brain and mastering the changes in the nature of the ore and the adjustment of the water volume in each part.

Density ore concentration is also called grinding concentration. It refers to the ratio of ore to water in the grinding machine barrel. It can be judged by the measurement result of the ore concentration of the grinding machine.
