Premium: Measuring density in grinding circuits

Are you struggling with your ball mill or cyclone operation? In grinding circuits, operators are managing different pieces of equipment. This whitepaper describes the purposes and benefits of measuring density in different applications in the grinding circuit. First, a short introduction to the grinding process and control purposes are given, followed by five key reasons for measuring density.

The grinding circuit

In general, the grinding circuit is composed of a powdering or pulverizing process and a classification process. In most sites a ball mill is used for grinding, to produce fine particles, and a (hydro) cyclone is used for classification, to separate the fine particles from larger particles. The finer particles are forwarded to the next process stages, while coarse particles are returned to the ball mill for regrinding.
