The UltraDRY dewatering screen can be added to a new or existing system

McLanahan’s new UltraDRY dewatering screen can be added to a new or existing system to create a drier, ready-to-sell product. Customers can achieve moisture content as low 7% by adding a McLanahan dewatering screen to the end of their screw washer, says the manufacturer, adding that this creates a drier product that is easier to sell. It also allows better site stockpile management with a shorter inventory cycle, making the customer’s site more efficient.

The Ultra line focuses on a set of standardised units that can be containerised for shipping and supplied quickly.

McLanahan says that its dewatering screens that are part of the UltraDRY system have a high G-force, creating a deeper bed depth, a drier product and with more product processed.

Drive motors on the UltraDRY are oriented to ensure that screens do not need a brake or a VFD (variable frequency drive) to stop the side motion of the screen. Additionally, it can come equipped with a divided deck design so that two separate products can be made on the same screen.

A slurry pump can be added when pairing the UltraDRY with a screw washer to divert the screen’s underflow water back to the screw’s feedwell. McLanahan says this location is ideal for water placement as it limits the system’s water usage and allows material at the top of the screw to stay cleaner and drier. Also available is an optional spray bar, designed to allow operators to scrub away any remaining debris and put the final touches to their product.
