Abstract:
A process for measuring particle size and concentration of a slurry according to on-stream analysis is provided wherein a slurry to be measured is impacted at a given velocity against a plate to measure impact energy thereof, simultaneously with light transmission of the slurry being measured, the results of the individual measurements are supplied as information to a data memory collation device to check the information with data previously stocked in the device, thereby converting the information into the corresponding slurry concentration and average particle size.
