Grinding operators frequently measure two types of pulp concentration: discharge concentration and overflow concentration. Consistent concentration measurement allows for real-time monitoring of changes in pulp concentration, which is crucial for ensuring the required fineness is achieved. Regular concentration measurements, over time, enable operators to determine the relationship between concentration and fineness based on mill discharge and classification overflow patterns, sometimes even without measurement.

The most important aspect of concentration measurement is ensuring operators have a clear understanding of the situation, allowing for timely adjustments based on concentration changes, stable operation, and maintaining the required concentration for beneficiation operations, which is especially important for flotation.
