Estimation of pulp viscosity and grinding mill performance

It is well known that the density and viscosity of a mill pulp have optimum levels for grinding efficiency and sophisticated control loops are employed to control pulp density in industry. However these control loops rely on a number of plant measurements and often the input data will not permit effective determination and control of the mill pulp density. The use of a single remote pulp
