All three discharge conveyors fold hydraulically for transport

Terex Finlay says this self-contained plant can be ready for
transportation in less than 30 minutes.
A 1050 mm wide variable speed belt feeder, with hydraulic
gearbox drive, is standard and the hopper has a capacity of 8 m³
capacity. It can be fitted with either a 14 ft (4.27 m) tipping grid
or 12 ft (3.66 m) vibrating grid.
But there is also still a strong market for fixed crushers and
stand-alone components for crushing and screening plants.

erex Minerals Processing Systems has started to design and manufacture wheeled
mobile crushers at its Hosur, India plant for distribution to Africa, Asia, Eastern
Europe and the Middle East, as well as India.
Jaideep Shekhar, executive director of materials processing India said, “The wheeled
plants have been designed and manufactured at our Hosur facility for nearly two years now
but we are excited at the opportunity that this range has now been expanded and we have
the ability to export globally.”
The range comprises the WJ1175 jaw, WC1000 and WC1300 cone and WV2000 vertical
shaft impact (VSI) crushers with high-stroke vibrating grizzly feeders and inclined screens.
They are all-electric machines that can be used in a range of primary, secondary, territory
and quaternary crushing applications.
The cone and VSI crushers feature a four-deck screen, allowing them to produce four
sizes of product. The jaw crusher meanwhile features hydraulic closed side setting (CSS),
while a standard feature of the cone crusher is Terex’s System 2-PLC programmable
electronic control system.
All four of the models made in India feature removable wheel bogies for transportation.
three new crusher units in the last 12
months. The company says it built them
specifically for the Chinese market, with
a simple yet robust and versatile design.
The high capacity DY single cylinder
hydraulic cone series, for example, offers
more performance and less weight than
the previous PYYX range. It has a wide
range of discharge sizes, and Shanbao says
it is easy to maintain.
The PV jaw crusher series meanwhile
can handle materials with a compressive
strength up to 320 MPa and feed sizes up
to 600 mm. Key features include a new
chamber design to deliver better crushing
performance, a fully-welded frame for
rigidity and reduced weight, simple
mechanical adjustment of the discharge opening and a motor
mounted directly to the frame.
Also new is the VI range of vertical shaft impact crushers, which
are designed for shaping and sand manufacturing applications.
The company says the range offers a large crushing ratio and
production volumes, while at the same time being flexible
enough to be used in different applications.
W.S. Tyler has launched a 4 ft (1.22 m) wide version of its
F-Class vibrating screen. Due to its consistent G-Force, the
F-Class is said to reduce blinding and pegging, even when
screening sticky material, and is now available in widths from
4 ft (1.22 m) to 10 ft (3.05 m).
The F-Class features a shaft with two eccentrics, which the
company says handles material volume spikes without losing
momentum. As the eccentric shaft turns, the screen body follows
the shaft movement. Counterweights on each screen reduce the
amount of vibration transferred to the supporting structure,
meaning multiple screens can be placed side by side with
minimum investment in heavy structures. The design also keeps
noise to a minimum.
The continual circular screening action produces a constant

hour Mobicat MC 110 Z and MC 110 R mobile jaw units.
