On-line measurement of charge position and filling level in industrial-scale mills

A simplified view of the sensor is shown in Fig. 1. The mill has a number of lifters on the inside of the mill shell. One of these lifters ("1" in Fig. 1) is equipped with a spring plate whose deflection is measured by the strain gauge ("2" in Fig. 1). As the mill rotates and the...

Summary:A simplified view of the sensor is shown in Fig. 1. The mill has a number of lifters on the inside of the mill shell. One of these lifters ("1" in Fig. 1) is equipped with a spring plate whose deflection is measured by the strain gauge ("2" in Fig. 1). As the mill rotates and the lifter with the sensor dips into the charge, the force acting on the lifter increases, which in turn causes a deflection.
