Abstract
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.

A process for measuring particle size and concentration of a slurry according to on-stream analysis, characterized in that a slurry is impacted at a predetermined 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 therein suggesting the interrelation between concentrations and particle sizes of slurries, impact energy at a predetermined velocity and light transmission, thereby converting the information into the corresponding slurry concentration and average particle size.
