FLSmidth equipment for Mufulira smelter

Mining and minerals processing equipment

manufacturer FLSmidth is in the process of

delivering an EIMCO®-Clarifier-And-Thickener

(E-CAT®) and a Shriver® filter press to Mopani

Copper Mines in Zambia for its Mufulira

smelter. The equipment removes and dewa-

ters dust particles from the water system.

Ricus van Reenen, Sales Manager:

Products at FLSmidth, explains that

FLSmidth’s E-CAT® technology, which

boasts no moving parts at all, combines

optimised flocculation, high rate clarifica-

tion and high density in a single compact

unit. It streamlines liquid-solid separation

flow sheets by optimising chemical set-

tling aids and providing a dedicated escape

route for displaced free liquid.

The fact that there are no moving parts

translates into a lower cost and lower energy

consumption, meaning reduced mainte-

nance in the long run. The E-CAT® also has

a smaller surface area than conventional

thickeners and therefore a smaller footprint

that optimises space on constrained sites,

particularly in remote locations in Africa.

In addition, the self-diluting feed makes

for optimal flocculant utilisation, while

no external dilution pumps are necessary

either. Good overflow clarity means that

effluent can be re-used while the dense

underflow cuts down on the energy needed

for drying. The smaller ponding area neces-

sary alsomeans a reduced handling volume.

Shaw Controls, a company within the Zest

WEG Group, has extended its product

range to encompass low voltage (LV) and

medium voltage (MV) applications. It man-

ufactures switchboard panels and control

systems from 24 V up to 36 000 V (36 kV)

for the industrial, mining and infrastruc-

ture sectors.

“Shaw Controls offers a complete

product line fromMV switchgear to LVwith-

drawable Motor Control Centres (MCCs),”

Valter Luiz Knihs, Group Automation

Shaw Controls extends its product offering

& Systems Director, says. These locally

manufactured products are indepen-

dently certified in accordance with the IEC

62271-200 and IEC 61439-1/2 standards.

According to IEC specifications, LV cov-

ers applications up to 690 V, while the MV

range is from 1 kV up to 52 kV. In addition,

Shaw Controls has recently received ISO

9001 accreditation from Bureau Veritas.

LV switchboard panels range from SC

100, SC 200 to SC 300 models, which can

be configured for various applications at

different fault levels and current ratings.

This gives Shaw Controls the flexibility to

be able to offer fit-for-purpose solutions. A

recent addition to the Shaw Controls prod-

uct range is the CCM 03 ZA withdrawable

MCC which is an already well-established

product of WEG Brazil. This highly success-

ful MCC solution will now bemanufactured

in South Africa.

All products include both a mechanical

and electrical interlock system to ensure

maximum safety, while the construction

itself is robust. Switchgear panels are

manufactured in bent steel profiles and

enclosed on all sides by steel plating. Over-

pressure relief devices in the top provide

for pressure relief in the event of internal

arc. Shield-type MV switchgear has metal

divisions separating the compartments.

The general busbar configuration

comprises one or more rectangular bars,

manufactured from electrolytic copper

with tin-plated fittings. The LV compart-

ment is located in the upper front part,

which houses the measuring instruments,

protection relay, terminals, thermostats

and contacts. This is completely isolated

from the MV via a steel plate, with its own

closable door.

The Zest WEG Group recently also

announced a significant expansion of Shaw

Controls’ manufacturing capabilities. This

is to cater for the significantly extended

product range as well as the increased

demand for Shaw Controls’ E-Housing

solutions. This expansion will include the

design and establishment of a 2 000 m

standalone E-House and container con-

version facility. Shaw Controls’ E-Houses

represent a cost-effective alternative to

traditional containerised solutions manu-

factured in standalone marine containers.

The expansion of Shaw Controls is in

line with the Zest WEG Group’s strategy

of extending its manufacturing capability

to boost its presence in the local market

and in Africa, which is perceived as a major

growth area. “Our aim is to position the

Zest WEG Group as a regional hub of WEG

and in so doing position Shaw Controls as

the number one panel builder and systems

integrator in Africa,” says Louis Meiring,

CEO of the Zest WEG Group.

Low voltage, fully withdrawable Motor Control Centres

(MCCs) form part of the Shaw Controls product line.
