Envites - Slurry thickeners

Slurry particles drop through the settling room to the bottom of the thickener and the released supernatant rises counterflow to the overflow trough and is drained for further treatment. The overflow trough with an adjustable overflow level is created on the central cylinder or on the peripheral jacket.

Beginners guide to thickeners - Metso Outotec

2017-6-16  Many thickener installations operate with water recovery below design limits largely through conservative control and low prioritization of thickener optimization. The operation of the thickener must accommodate fluctuations – control for disturbances – in the process feed stream to deliver a clear overflow and thickened underflow.

These deliver slurry into a flocculation chamber before dispersing through an exit gap into the thickener tank. The trough most innovatively ensures flash mixing, and highly uniform solids dispersion inside the aggregate growth chamber. Initial examination adopted a multiphase Eulerian mathematical model to explore geometric configurations ...

What Is the Difference Between a Roux and a Slurry

2019-7-8  Slurry. Slurry, on the other hand, achieves success through cooling, not cooking. The thickener uses a cold water (or milk) and cornstarch mixture made in advance and then added to the liquid in need of thickening. Yes, that’s right. It uses cornstarch (no gluten) so we already know that it will be a top competitor for California.

Pumping Mining Slurries with a Peristaltic Pump: Verderflex

Pumping Mining Slurries with a Peristaltic Pump. Hose pumps can circulate slurry SGs of 1.6 to 1.8 or up to 80% solid content. The traditional centrifugal pump loses efficiency when the slurry SG reaches 1.3 or 30% solids. With this limitation, slurry pumps have significant process water demands : on a plant processing 75 tonnes of ore per hour ...
