Jaw update increases energy
Significant changes to KPI-JCI and Astec Mobile Screens' new genera-
tion of Vanguard Jaw Crushers are said to reduce maintenance and
increase energy and performance. Operator investment is protected
through replaceable wear parts such as the jaw die seats and barrel pro-
tector plate. Maintenance is simplified with a new jaw die wedge design
that holds the jaw die in place. The manual shim adjustment method
was eliminated as the closed-side setting is now adjusted through the use
of hydraulic cylinders. New design components — including increased
stroke, toggle angle, and flywheel inertia — enable operators to increase
performance. The largest crushers in the line crush with a 1 1/2-inch
stroke that opens wider and compresses material more to get material
through the jaw quickly.

Streamlined filter press
McLanahan Corp. introduces its own line of filter presses.
Designed to help operators better use wash water and land
resources, the filter presses are said to eliminate the need
for settling ponds. The dry, easy-to-handle byproducts pro-
duced through the filter presses can be safely handled and
disposed of. The filter press line is said to use few moving
parts and was engineered with a single hydraulic cylinder.

High output tracked jaw crusher
Irock expands its product line to include the TJ-3046 Tracked Jaw Crusher.
The primary jaw plant is designed for medium-scale operators in quarrying,
demolition, recycling, and mining applications. It features a 13-cubic-yard
feeder and a grizzly pre-screening grid. An optional sensor can be fitted to the
jaw and controls the feed rate to the crusher to maximize production. The
jaw crusher has an inlet opening of 46 inches by 30 inches and is equipped
with a hydraulic wedge adjustment to give operators control of product size
down to 2 inches. The high-swing jaw is said to generate an aggressive crush-
ing action and accelerate movement of material into the crushing chamber.
A 48-inch crusher discharge conveyor can stockpile up to 11 feet, 6 inches.
The 110,250-pound unit can be equipped with a wireless remote control and
is powered by a 350-horsepower Cat C-9 Acert Tier 3 engine. It can produce
up to 445 tons per hour.

Secondary belt cleaner
Flexco's Y-Type Secondary Belt Cleaner improves belt-
cleaning efficiency while easing maintenance, the manu-
facturer says. The cleaner comes with 3-inch urethane
blade segments that conform to worn or damaged belts,
while the spring tensioner keeps consistent blade-to-belt
contact and constant pressure on the belt. Available in
sizes to fit belt widths from 18 to 48 inches, the second-
ary cleaner is available with a standard abrasion-resistant
purple blade. Blades can be removed or replaced indi-
vidually or at one time.
