Mobile Tracked Screening Plant
The 893 Mobile tracked screening
plant is a highly versatile and aggressive machine engineered and built for
working in large scale quarrying, mining, construction and demolition debris,
topsoil, recycling, sand, gravel, coal, ore and aggregate applications. The
plant has the capacity to process at a rate of up to 800 tonnes per hour and
can be fed either by a tracked mobile Crusher, shovel or an excavator.Depending
on the application the working angle of the aggressive screenbox can be
hydraulically adjusted to between 14 – 18°.
· A key feature of the machine is the capability to change
the working angle of the hopper/feeder. The working positioned can be lowered
so that it can work with ease with a mobile crusher. The hopper/feeder working
position can be raised to provide a reduced feeder angle when operated in
direct mode from an excavator or shovel. The screen box top deck can be fitted
with a variety of screening media including; Mesh, Punch plate, Bofor bars
& Tines. The bottom deck can be fitted with mesh, punch plate & cascade
fingers. This fully self-contained plant can be hydraulically folded and ready
for transport in less than 30 minutes making it the ideal machine for large
scale contract screening projects where a highly productive and dependable
screen is paramount.
· Versatile aggressive screen box can be easily adapted to
suit many applications.
· Modular configuration screen box with 6.1m x 1.8m (20` x
6`) top deck and 5.5m x 1.8m (18` x 6`) bottom deck screen.
· Screen box angle can be hydraulically adjusted to an
angle between 14 – 18°.
· Screen box discharge end can be hydraulically raised
600mm (24") to facilitate efficient and easy media access and changing.
· All stockpiling conveyors are hydraulic angle adjustable
with hydraulic extending head sections for maximum discharge & stockpile
height.
· Apron feeder angle adjustable, lower position to
accommodate crusher feed, high position provides reduced feeder incline angle
when operated in direct feed mode from excavator/loader.
