in support of operations. The largest project undertaken so far
has been in Kenya where concrete has been mixed for use in the
construction of a training facility.
Nurock’s technical teamworks closely with the Royal Engineers
to provide assistance and parts when required. The mixers are
expected to be in service for the next 10 years.
Twin technology
Italy-based manufacturer Simem offers a wide range of mixers.
The company is currently promoting its MDC and MSO
models.
The Simem MDC continuous flow mixer adopts twin shaft
technology and is especially designed for zero slump concrete
and RCC.
The MDC is offered in two main variants, MDC200 and the
MDC500. Options include side overflow discharge, extended
tank, stainless steel tank, and inflows for water or any other
materials.
The Simem MSO is also a twin shaft mixer. Available in
models ranging from 1 m
3
to 9 m

, the mixer is suitable for any
type of concrete, from wet to zero slump, with aggregates up to
200 mm in diameter.
All Simem models come with the company’s Mixer Mind
electronic check system, which monitors temperatures and
power consumption.

Liebherr takes control
Quick reaction times and maximum precision with MPS
L
iebherr has upgraded its MPS system for the control of concrete mixing plants. The software-
based Litronic-MPS III solution now provides a real-time capable operating system to manage
plant outputs and concrete quality.
The Litronic-MPS III provides a comprehensive overview of functions for the mixing technician to
provide uniform consistency in concrete production. The two-monitor control system provides data on
customers, material orders and concrete types on the left monitor, while the right monitor displays real
time interactive plant details.
The system comprises a computer, a four-channel precision amplifier, keyboard, two monitors, VPN
router for the Teleservice and a control panel with PC box and software. The PC box is equipped with a
ventilator and fine dust filter.
The Litronic-MPS III can be adapted for each plant. It can be connected to CAD/CAM processing
systems, remote access terminals and controls of bucket transport systems or gantry cranes. It is
also compatible with interfaces for concrete laboratory programmes such as Prolab, or with invoicing
programs.
For smaller plants the Litronic-MPS III LV microprocessor control can be operated with a single
monitor.
The software is available in 20 languages, with more languages under development or available on
request.
