Particle size analyzer |
| abstract |
Method and apparatus are provided for a simple onstream particle size analysis. The device can be a single or multiple channel device. The percent solids is continuously measured both in a sample stream and in an internal reference stream, containing particles below a predetermined size. A semi-permeable hydraulic system is used such that the particle mass concentration in the internal reference stream can vary and remain proportional to the particle mass concentration of particles below the predetermined size in the sample stream. The apparatus provides a compartment having two cells separated by a perforated barrier and means for measuring the pulp density of the slurries in each of the cells. |
