Track-mounted primary jaw

Telsmith, Inc., introduced its new track-mounted
primary jaw crushing plant, the Quarry-Trax Model TJ3258, at ConExpo-Con/Agg.
Engineered to deliver high yields with superior reliability, the plant’s
Telsmith 3258 jaw crusher features a larger gape and a 58-inch-wide
crushing chamber, boosting crushing capacity by up to 15 percent over
similar sized units. The crusher uses PLC controls for ease of
operation. In the automatic mode, the crusher feed is maximized by
monitoring engine load, crusher load, and feed in level in order to
maintain a consistent choke feed. The crusher setting is displayed on an
on-board LCD monitor and adjustments are enabled through push button
controls.

All-weather, automated drill rig

Atlas Copco showcased its ROC D7C, a silenced
SmartRig surface crawler. SmartRig is a concept that facilitates a
variety of automation in drill rigs. The hardware is designed to operate
in every possible weather condition, and the software can be upgraded on
site. The units have built-in logging and monitoring functions as well
as support for diagnostics and fault finding. Through PC software, the
SmartRig control system electrical signals are generated to control the
hydraulic valves. This concept of a “dry cab” has no hydraulic pipes or
gauges and reduces noise for the operator.

Newly designed hydrocyclone

Linatex used computational fluid dynamics modeling
and specialist design principles to develop a new range of Linatex
Genesis Hydrocyclones to provide improved classification efficiency and
product recovery. An interchangeable inlet wedge allows operators to
quickly change the size of the inlet and to fine tune performance
without removing it from the process line. Feed slurry is introduced
into the body of the cyclone in a tall rectangular ribbon, which moves
the solid particles closer to the wall of the cyclone and minimizes the
distances traveled during the separation process.

Track-mounted crushers

Terex Pegson’s ConExpo-Con/Agg lineup included
three new track-mounted crushers: the large XA750 jaw, the XV350
vertical shaft impactor, and the SH250 horizontal impactor. The XA750 is
an entirely new jaw plant for larger quarry and recycling applications.
Featuring a modular design for maximum capacity, it boasts a
hopper/feeder section with live pre-screen that is removable for
transport if required. A one-piece hydraulically raised/lowered product
conveyor, extended dirt and fines conveyor, and Jaques 55- by 35-inch
jaw round out the plant. The XH250 HSI targets smaller recycling and
quarry operations while the XV350 VSI boasts an updated 1300 Maxtrak
chassis.

loader, designed for quarry, sand and gravel, and industrial
applications. It employs advances that allow operators to work
comfortably and productively in a variety of conditions. The wheel
loader boasts a net 332 horsepower and an operating weight between
71,585 and 74,010 pounds. Komatsu engineered all the major components,
including the engine, lock-up torque converter, transmission, hydraulic
units, and electric parts. It is equipped with the latest Komtrax
technology, which sends the machine operating information to a secure
Web site using wireless technology.

Pulleys eliminate high-stress areas

Continental Conveyor & Equipment Co. rolled out its
Continental JLV pulleys, which are designed around the application of
keyless locking elements between end-discs and shafts. Widely used in
high-tension pulley applications, the company expanded the use of the
technology below the level of high-tension pulleys. Key advantages
include the following: end discs are made from solid plates rather than
weld-in hubs; the bending moment at the hub is reduced without
sacrificing strength and durability; lighter pulley construction
provides similar durability to heavier pulleys; and the units feature a
stress-balanced design that matches stresses and deflections of all
pulley components and thereby eliminates high-stress areas in the
pulley.
