There are two types of slurry that the miners often insist on determining: the concentration of the ore and the concentration of the overflow.
Persistence in measuring concentration has the following meaning: It is extremely important to know whether the concentration of the slurry is changed at any time, and it is extremely important to ensure the completion of the fineness requirement; the concentration is often determined, and the concentration and the concentration can be judged according to the mill discharge condition and the graded overflow condition through a certain period of time. The relationship of fineness changes, even without measurement, can be based on discharge and overflow. Determine the concentration and fineness. The determination of the concentration, the most important thing is to make the operator know what is in mind, adjust according to the concentration change, stabilize the operation, and ensure the concentration stability required for the sorting operation, especially the flotation operation is especially important.The ore concentration is also known as the 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. 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% and 83%; in fine grinding, the grinding concentration can be lower, about 65% to 75%. The ore concentration of ore with different specific gravity should also be different. The concentration of grinding may be controlled to be higher than that of ore, and the concentration of grinding should be smaller when the proportion is small.
