The Latest Technology for On-Line Particle Size Distribution Measurement

Abstract

It was introduced a test example in which a jet mill line was automatically controlled using an online particle size analyzer, and also introduced sampling example from multiple process lines. In a jet mill line, an online particle size analyzer was installed at the mill outlet, and the raw material feed rate was feedback-controlled based on the measured particle size. The particle size of the mill product could be controlled with a delay of about 2 minutes. An example of sampling from two lines revealed that it is possible to perform sampling that responds instantaneously to line switching without contamination.
