How Does It Work?
The dewatering bin separates the solids and liquids from a dilute slurry stream. The size of the separated solid particles can range from fine sand to coarse gravel.
The size fraction that reports to the overflow can be specified by the client and final adjustment made during commissioning.
What Value Does It Add?
Many mineral and mining processes transport dilute slurry initially, but then have to deal with the burden of the superfluous liquid by over sizing downstream process equipment unnecessarily.
“The dewatering bin provides a compact solution to remove excess process liquid without the loss of valuable product.”
The decoupling of two stages of a mineral process is often achieved by a buffer storage facility. The dewatering bin design offers a wet bin storage facility where the solids can be stored in a saturated form over the short or the long term without agitation and extracted when required at a controlled rate and concentration.
Where is it used?
It is the nature of dredging to produce a dilute product stream that requires dewatering before introducing it to the process plant.
Batch operations require storage facilities from which material can be extracted on demand. The dewatering bin allows storage at the saturated concentration (which is higher than the transport concentration) without loosing solids during the dewatering.
Some processes are impacted negatively by the build up of fines. The dewatering bin discards the fines with the overflow, leaving the coarser product behind.
