- Becker Mining South Africa’s manufacturing
arm of communication and automation systems – has enhanced
its BRS 1 belt rip detection system with the launch of the newly
developed BRS 2.
“This belt rip detection system has been designed to increase the
productivity of conveyor belts by detecting belt rips as soon as they
occur,” says Tiaan Tromp, Becker Mining South Africa. “The BRS 2
system, which is used to detect longitudinal rips on steel cable and
fibre conveyor belts, prevents further damage to the belt by stopping
the belt drives in the event of a rip.”
Inductive loops, which are selected according to belt width and
rubber type, are encapsulated in a rubber flap and embedded into
the belt. The BRS 2 detects these inductive loops and defines and
numbers these loops, creating its own image of the belt and its loops
in real time.
At installation, the system carries out an identification run and the
processor of the belt rip detection system unit (BRS/CU) stores the
necessary data. Parameters include the succession of loops in the belt,
belt speed and start up time of conveyors. Stored values are protected
against power loss and can be entered or changed when necessary.
When the belt is in operation, these loops pass over the transmitter
and receiver which are positioned opposite each other on either side of
the belt. An electro-magnetic signal is transmitted via the inductance
loop from the transmitter into the receiver. Because this system has
recorded the distance between successive loops and belt velocity,
it can automatically calculate the time intervals between each loop.
The belt rip sensor that is embedded in the belt operates like a
bridge between transmitter and receiver of the belt rip scanner sen-
sor interface (BRS/SI). If a belt is ripped, the BRS/SI cannot measure
any analogue values from the destroyed loop.

lyde Bergemann Power Group
Americas
(CBAM), part of global Clyde Bergemann
Power Group (CBPG), announced that it has
recently been awarded a $180M contract
for air pollution control equipment from
a major United States utility. CBAM will
engineer, supply and commission a total of
twelve pulse jet fabric filters for particulate
control, 12 powder activated carbon injection
systems for mercury mitigation and six dry
sorbent injection systems for sulphuric acid
mist mitigation for twelve coal fired boilers
with a combined 5 000 MW of generating
capacity.
This order makes CBAM the leading sup-
plier of fabric filters and dry sorbent injection
systems to US power plants for compliance
with the Environmental Protection Agency’s
(EPA) new Mercury and AirToxics Standards
(MATS).The MATS rule will require existing
power plants to meet reduced emissions of
toxic air pollutants such as mercury, par-
ticulate matter, and acid gases. “We are very
pleased with receiving this important order”
said Hans Schwade, CBAM president and
chief executive officer. "CBAM’s comprehen-
sive offerings of emissions control solutions
and our highly talented team allowed us to
meet all of this important project’s require-
ments. We look forward to a continued,
mutually beneficial project together with our
customer.” Engineering work for the project
has already begun with material delivery
scheduled to start in spring of 2013. Fabrica-
tion will take place in Clyde Bergemann’s
new 165 000 square foot plant in Jesup, GA
where the company will generate some 70
new jobs. More detailed information about
this new facility will be forthcoming in a
separate press release. Franz Bartels, CBPG
president and chief executive officer, con-
gratulated the CBAM team and said “This is
a major success for the entire Clyde Berge-
mann Power Group.The order confirms our
strategy to invest heavily into innovative air
pollution control technologies and people in
the US market as well as expand domestic
manufacturing."
