EQUIPMENT
The MC1300 cone has been
added to Terex Mineral
Processing’s range of crushing
and screening modules
Tests validate
Cobra Pro
breaker
Atlas Copco recently carried out
comparative testing on the comfort and
safety of handheld breakers supervised by
TUV Nord. Three tests were conducted:
a 3-axis vibration measurement on
a Dynaload absorber according to
ISO28927-10:2011, a real work 3-axis
vibration test on concrete performed
by three operators according to ISO
5349-2:2001 and a real impact energy
measurement on a Dynaload according to
ISO2787.
The results showed that the hand-arm
vibration of the Atlas Copco Cobra Pro
is 3.8 on the Dynaload and 5.8 in real
work on concrete, with the tool displaying
an impact energy of 61 J and 1,470 W
output in the chisel. These are better
performance levels than claimed by Atlas
Copco for the tool. When combined with
its low emissions and noise level, this
means that the Cobra Pro is an ideal tool
for breaking, cutting, digging, damping
and driving.
New cone
from Terex
T
erex Mineral Processing has launched
a new cone crusher module, the CE
certified MC1300, that is intended
to increase the application and production
capabilities of its existing modular range. This
consists of a number of pre-designed static
and semi-static crushing and screening ‘plug
and play’ modules that bolt together on site
and require minimal on-site wiring.
According to modular product line
manager Mark Crooks: “With the addition
of the MC1300 to our modular product
line, we are now able to offer customers
increased production and greater application
capabilities. The MC1300 Cone Module can
be matched with other units in the modular
product line to create a system capable of
processing up to 270 tonnes/hour.”
The new cone module consists of Terex’s
TC1300 cone crusher powered by a 225
kW (302 hp) electric motor and features
an unrestricted feed opening and a full
range of configurations for short and long
throw to give a high degree of versatility,
and the all-roller bearing design improves
crushing efficiency. The TC1300 also features
hydraulically adjustable closed-side setting,
easy manganese changes and a weather
protected control panel with a user-
friendly interface. Other key features
include an extra-heavy I-beam
frame and a galvanised steel
structure including walkways,
steps and guard rails.

Magnum force
IRock Crushers has introduced a new three
model line-up of primary impact crushers in
the shape of the Magnum 15, 20 and 30, which
it says perform well when processing material
arisings from quarrying, demolition waste or
recycling.
All three feature Cat Tier 3/Stage IIIA
engines delivering 261 kW (350 hp), 328 kW
(440 hp) and 410 kW (550 hp) and offer a
maximum throughput of 350, 500 and 650
tonnes/hour respectively. Each includes three
auxiliary outlets for transfer or stacking
conveyors and is fitted with a PT Tech clutch
that decreases power loss and increases fuel
efficiency, said IRock. The three units can be
fitted with the company’s patented Hydraset
Hopper that operates from an internal power
pack to allow it to be easily detached and
placed on a trailer in minutes without the
need for a lifting device. This is essential on
the Magnum 30, since it cannot be legally
transported without removal of the hopper as
a result of weight limitations.
A vibrating feeder with heavy duty two-
stage tapered grizzly removes fines to allow
only large material into the hopper. Feed
openings on the three machines range in size
from 1 x 0.8 m (40 x 32 inch) to 1.4 x 1 m
(56 x 43 inch). Hydraulically adjustable
aprons with three stage crushing allow
better control over sizing and the four-bar
impactor design offers maximum material
reduction that minimises wear and enhances
performance and production, says the
company.
