Actor 3 - the postweighing
Samples from the fluidized bed are automatically weighed in the Erlenbach bulk density control system (ESN10). In this unit, too, another exact weighing stone is used, which should be checked and calibrated regularly. The bulk density determined by the ESN10 is transmitted to the control system of the preexpander. This way the bulk density is recorded and can be used for later control, evaluation or quality aspects. On the other hand, the weighed bulk density is used to control the initial weight. If there is a deviation in the bulk density, the system automatically corrects the value of the initial weight. Thus, the use of the ESN10 bulk density control system guarantees an efficient use of raw materials and contributes to a maximum economic use of the pre-expansion system. See more in our animation.
