Efficiency drive
together with less energy consumption.”
There was plenty of attention on one of
the company’s latest releases at theBauma
China exhibition held in Shanghai – the
Q1441 mobile tracked crusher featuring
itsC1421Prisec Impactor box.
The company has redesigned the
crushing chamber to allow the base
crusher to easily be switched between
primaryand secondarymode toeffectively
give users twomachines in one.
It retains many of the features of
the previous model, including direct
drive, user friendly programmable logic
controller (PLC) system and remotely-
operated inlet opening adjustment on
a machine that features low wear, easy
maintenance and low cost operation.
Meanwhile Shanbao, the Chinese
crushing and screening equipmentmaker
in which Sandvik owns a majority stake,
also usedBaumaChina to launch a range
of mobile crushing and screening units
for the globalmarket.
This included tracked, wheeled and
modular units, featuring primary,
secondary and tertiary crushing and
screening equipment as part of an entirely
new venture.
Delivering machines that are both
robustly-designed and fit for their respective markets remained
a core priority for many companies including Austrian
manufacturerDSB Innocrush.
Its general manager Dieter Durstmuller, explained that
responding to customer feedback had been an integral part in
establishing itself in a competitivemarketplace.
He said, “One of the biggest changes and challenges we have
faced has been the introduction of a lot of new technology.This
includes dealingwithnew emissions regulations.
“We have found that our customers do not want equipment
that has too many options - especially with excavator drivers
having to operatemany systems by remote control.”
The manager added that its early decision to develop its
Innodrive operating systemhadproved critical in reducing levels
ofmaintenance-intensive components for
crushing equipment.
He added that moving towards Tier
4 emissions technology had also posed
challenges, but said that rules permitting
its phased introduction were proving
effective inmanaging the switchover.
Key uptime
As a number of manufacturers including
Metso have expressed, ensuring as much
operational uptime as possible plays a key
role in crushing operations.
Consequently, the company has developed its Orange Series
Rotor for vertical shaft impact (VSI) crushers. The company
said use of the new system, productive uptime can increase
substantially in terms of the extended life of parts and faster
service.
Maintenance is also simplifiedby reducing the number ofwear
parts by -30% and incorporating -25% less components.This is
achieved by integrating several components and using less fixing
points.
The company explained that remote monitoring of crushing
data from quarries is becoming a crucial element in mobile
crushing and screening applications.
In response, Metso has developed complete fleet management
and automation systems that are designed for all its Lokotrack
rangemobile applications.
Thecompany’sfleetmanagement system
consists of an IC process control system,
a satellite uplink and a DNA Report
portal. This collects and presents a daily
overview of the operating fleet including
effective hours, fuel consumption and
unit locations.
Another of its major releases comes in
the form of a joint venture with Liugong
to produce a 40 tonne mobile crusher,
whichwas on show at BaumaChina.
It has been built around Metso’s
>
Sandvik-owned Shanbao
launched a new crushing and
screening line at Bauma.
Dsb has supplied one of its crushers, an Innocrush
35, to Ammann, working on a project at Sasbach
on the Franco-German border.
Metso orange rotor aims to ensure
maximum operating uptime.
The first fruits of Metso and Liugong’s
joint venture in china is the 40 tonne
