A new small multislope screen has been developed locally by IMS
Engineering to meet the needs of the local and African diamond
industry.
The new 1,5 m 5 4,8 m OmniScreen will be used for alluvial diamond
screening. It is a relatively small screen with the advantages of a
multislope deck configuration offering improved feed stratification
on to the screen thereby increasing the overall screening
efficiency and, because it is a relatively light but robust unit
for its high G-force, is well suited for mobile plant
installations. Although the screen has been designed and
manufactured in South Africa, it developed from cooperation between
extraction of li metal from spodumene ore
IMS Engineering and the IMS group company Omni, in Brazil.
The screen is fitted to the mobile crushing plant supplied to
Namdeb in a cooperation between IMS Engineering and Haahjem, from
Norway. Together with the well-known, high-efficiency Kawasaki 1000
Cybas cone-crusher and the world-renowned Haahjem undercarrgold left in the trailingsiage and
conveyor system, the new screen is believed to be a well-matched
combination.
The latest screen from IMS Engineering is a modular linear movement
vibrating screen suitable for horizontal, inclined or multisloped
installation in a single, double or triple-deck configuration.
Substantially lower weight and less power consumption with high
aportable brick equipment supplier in uscceleration in the preferred linear movement results in greater
capacity and improved efficiency for all applications in the most
cost-effective method, which has made it well accepted, both
locally and internationally, where its cost-efficient performance
is valued in a variety of applications.
It is expected to appeal to the lokaolin crushing equipment for salecal as well as the export markets
seeking increased efficiencies from a reliable and proved linear
screen. Other news from the Gauteng-based company is that it has
supplied a Hazemag hard-rock impactor to Scirocco Enterprises, in
Lusaka, Zambia, to crush limestone and marble for aggregate.
The Hazemag AP-K 1010 will be used as a secondary crucirculating load for ball millsher together
with another Hazemag hard-rock impactor already operated by the
quarry.
Scirocco had previously bought machines from Europe. However, IMS
Engineering’s ability to deliver a top-quality product promptly and
at a competitive price influenced it to choose the Hazemag from the
South African company, which has been the manufacturing licensee
for the product for Southern Africa since 1962.
The hard-rock impactor combines the advantages of the Hazemag range
of primary and secondary impactors with the ability to crush very
hard and abrasive materials, such as gravel, granite, gneiss, glass
and fireclay. A particularly impressive feature of the crusher is
its high crushing reduction ratio and its ability to generate
cubical, fissure and stress-free product, a critical requirement of
the aggregates industry. The product size distribution from the
impactor can be adjusted to meet customer requirements due to the
adjustable features built-in to the impactor’s operation and
design. The design of crushing implements and housing liners with
the use of highly wear-resistant chromiummolybdenum materials, and
the fact that many of the housing liners and all of the impact
plates are interchangeable within the impactor, provides for
economical operation. In the case of the Scirocco machine, IMS has
fitted a Vogel centralised manual grease lubrication system
supplied by sister company IMS Industrial Products.
