Isodry Decanter Centrifuge
|
Offering continuous duty without an operator, Isodry™ decanter centrifuges can separate tailings down to its finest components, including silt and clay, with high availability.
Isodry™ decanter centrifuges use centrifugal force to reliably separate solids in the most demanding conditions. A screw conveyor rotates inside the machine at a different speed to the bowl, forcing the solids to one side of the machine while the liquid overflows out the other side.
Equipped with heavy-duty gearboxes the solid bowl or decanter centrifuge can separate up to 65-90% dryness, depending on particle size and the solids’ specific gravity.
This flexibility makes Isodry™ decanter centrifuges ideal for a variety of tailings dewatering solutions, including continuous dewatering, removing silt and clay or even working with ultrafine particles below 10µm.
Fully automatic and remote controlled, Isodry™ decanters are designed for remote operation without operators to deliver long wear life with minimal maintenance, with anti-abrasion wear protection and tailings-optimised scroll geometry.
Key features
Fully automatic, remotely controlled machine
Solid and robust design for demanding operating conditions and minimum maintenance
Heavy duty gearbox with the highest torque currently available on the market
Conveyor and optimised scroll geometry designed for tailings
Optimised wear protection for abrasive media with wear elements designed to be replaced after one year
Wetted material produced in carbon steel for non-corrosive tailings. Also available with stainless steel
Scrapper system on solid outlet to ensure the transport of the stickiest solids
Machine is designed to have a rotor exchange less than a shift to minimise the turn downtime
On-site service available worldwide
The Isodry™ decanter centrifuge system comes with the following features:
Installation in a concrete base
Feed box with slurry valve and water valve for flushing feed line and machine
Warman® feed pump and a Linatex® hose for connections
High capacity machine with up to 1,100mm diameter bowl at a low angle and deep pond
Centrate hopper
Cake hopper connected to conveyor or pump
Sump pump for centrate and wash rejected back into feed thickener
VSD (variable speed drive) for controlling the machine motors and feed pump
Automatic control system which monitors the machine’s health, controls cake dryness in real time. In case of alarm or shut down, the machine is automatically flushed and washed with water from the thickener overflow.
