What is Bentonite?
Bentonite is absorbent aluminium phyllosilicate clay. The main uses of bentonite are in drilling mud and as a binder, purifier, absorbent, and carrier for fertilizers or pesticides.
Bentonite slurry is one of the most common excavation fluids used in constructing a diaphragm wall. Bentonite clay (in powder form) and water are combined in a colloidal mixer and clay particles bond to each other and set to form a gel when left to stand for a period of time.
An original equipment manufacturer have been installing Pinch Valves onto their slurry handling equipment for many years.
