Blog: Measuring density in grinding circuits 1/3

2020-3-20 · In this blog you can read there are multiple reasons for measuring density in the grinding circuit. In most sites a ball mill is used for grinding and a (hydro) cyclone for classification. The slurry needs to be continuously monitored and controlled. Density meters efficiently help operators to monitor and control the grinding circuit, optimize it and prevent process failures.
