The Sizing Selection of Hydrocyclones

Historically, classification has been defined as the particle size of which 1% to 3% reports to the cyclone overflow with coarser particles reporting to the cyclone underflow. Recent investigations have defined classification as the particle size of which 50% reports to the overflow and 50% to the underflow, or the so-called D50 C point.

Jun 08, 2021  After determining the graded particle size, a certain pressure is required to adapt to it. If the pressure is too high, the fine particles mixed in the sand will increase accordingly. If the pressure is too small, the coarse particles mixed in the overflow will increase, which will greatly reduce the classification efficiency of the hydrocyclone.
