Control Strategies for thickeners
ResultWhen the density in a tailing thickener is lower than the target, it can cause water loss into the underflow. This can shorten the life of tailing dams. On the other hand, when the density is higher than the target, it can lead to pump blockage during material transfer to the subsequent process stage.
