The new two-deck pre-screen is said to minimise the amount of undersized material that passes through the chamber, reducing zwear costs and increasing the amount of final product by up to a claimed 30%.
“Several of our customers are trying to produce products that have a significant amount of fines in the feed material. The pre-screen allows producers to remove those fines while also minimising the amount of rejected in-spec product,” says Tim Harms, crushing and screening product manager at KPI.
The flagship plant features KPI-JCI (Johnson Crushers International) and Astec Mobile Screens’ patented hybrid power. Hybrid equipment gives operators rugged, high-performance machines with flexible power options in one convenient package.
With the patented hybrid solutions, producers can operate using either line power or genset, or use traditional diesel power when electric power is not available.
The most ecological source, line power, offers producers several operational and environmental benefits. Reduced noise levels, no engine emissions, the ability to run indoors and not having to refuel the equipment create a cleaner atmosphere for communities, while decreased operational and maintenance expenses create opportunities for producers. The patented hybrid option can also increase production in dirty and dusty environments, while lowering the processing cost per tonne.
