Portable Metso machine combines crushing, screening

Metso introduced two new portable plants Monday during ConExpo-Con/Agg 2014 in the Lokotrack LT220D crusher and the Lokotrack ST2.8 screen.

According to Adrian Wood, Metso’s vice president of sales support for crushing and screening equipment, the LT220D will revolutionize the way aggregate producers operate. Wood says the key to Metso’s new crusher, which blends crushing and screening, is a centrifugal conveyor.

“We take the material along the conveyor and turn it 180 degrees by centrifugal force,” Wood says. “The machine becomes very compact. You have a very small area where we transfer [material]. That’s what makes [the machine] transportable.”

Advantages Wood expects producers to experience with the LT220D are less downtime and less trailer transportation.

“We believe that because you have one machine instead of two you’ll have 100 hours’ less downtime [per year],” Wood says. “We think there will be about 600 miles less trailer transport [per year].”

He adds that Metso’s LT106 jaw crusher is an ideal machine to partner with the LT220D.

The second new Metso machine, the ST2.8 scalping machine, consumes less fuel than its predecessor, according to Wood. Another difference between the ST2.8 and its predecessor is the machine’s stroke.

“If you’re screening sticky, dirty material, you need to throw the material so it breaks open,” Wood says. “This machine actually has a 15-mm adjustable stroke – the biggest in the industry. Because we have that and we’re working with sticky material, it’s more efficient.”

Also new from Metso at ConExpo-Con/Agg is an HP3 cone crusher. The company touted a new program, as well, in Metso Quarry Supplies. Metso’s goal is to be a one-stop shop for quarry products.
