In most coarse crushing plants the instrumentation is used primarily for monitoring the operation and for controlling feed or discharge equipment in such a manner that the crusher will not be damaged. This level is often sensed by the use of gamma switches. These devices consist of a radio-active source and a detector.

Multivariable decoupling internal model control … Grinding circuit (GC) of mineral processing industry is characterized by its multivariable, severe coupling and multiple time delay nature.
The grinding circuit under study operates in a closed-circuit as shown in Fig.1. It consists of a ball mill, a hydrocyclone, a sump and other associated conveying sets. Fresh ore from an ore bin is fed onto the conveyer belt by a vibratory feeder at a certain speed, and then is conveyed into
Water impacts the grinding process, therefore the efficiency of the ball mill can be greatly improved by better water dosage. This alone could improve the efficiency with 5-15% according to 911 mettalurgist. When this is combined with a control strategy, the improvement rate could be even higher.

A typical decoupling capacitor in a digital circuit is of 0.1/μF. The decoupling capacitor has a distributed inductance of 5nH, and its parallel resonance frequency is around 7MHz, which means that it has a good decoupling effect for noise below 10MHz, and has little effect for noise over 40MHz.
Grinding circuits are fed at a controlled rate from the stockpile or bins holding the crusher plant product. There may be a number of grinding circuits in parallel, each circuit taking a definite fraction of the feed. An example is the Highland Valley Cu/Mo plant with five parallel grinding lines (Chapter 12 ).
