McLanahan Dewatering Screens offer multiple advantages for construction and specialty
mineral and aggregate producers, including a dry “drip-free” product that other types
of equipment cannot provide. Dewatering Screens have several functions: dewatering,
desliming, degritting, rinsing, scrubbing and washing. They feature heavy-duty screen
media for high capacity applications. Side frames and beams are Huck-bolted together,
not welded, so individual components can be replaced. They also have a combination of
standard wear-resistant side wear linings, optional deck dividers and dams. Performance
flexibility is enhanced by variations in screen media and the use of deck dividers.
Reduce Moisture
Surface moisture as low as 8 percent has been experienced with Dewatering Screens;
however, final moisture is dependent on surface area, surface morphology, and contact
angle. Finer materials, such as those processed in fines recovery systems where the
material is 100 percent passing 100 mesh (150μm), will dewater to a drip-free consistency,
which conveys and stacks, but may have a surface moisture content of more than 20
percent.
Dewater More Than One Product
McLanahan’s personnel pioneered the use of deck-dividers to allow two or even three
products to be dewatered at one time. Producing a fine product on one side and a
coarse product on the other with the facility to blend is part of the standard offering from
McLanahan. Process Engineers will assist with the application to ensure all factors are considered.
