Why the need for real time gap control and optimisation of crusher circuits?
We often think of plant feed as being homogeneous, uniform and well suited for steady state operation however in reality the normal day to day operations of a mineral processing circuit finds plant feed to be variable in size, shape and physical properties.
These variances are caused by numerous factors including mining in different pit areas, operating at different depths, upstream crusher performance, circuit screen efficiency and even current site weather conditions. Each variance can result in the crusher’s feed material changing substantially.
Crusher performance itself is also subject to change depending on liner condition and wear rates. It is evident that crusher performance (specifically crusher throughput and crusher product size distribution or PSD) can change rapidly and true steady state operation is seldom achieved for continuous periods.
