The contract to design, manufacture and install two high- angle
conveyors (HACs) for the pebble-crushing circuit project at
Palabora Mining has been awarded to Continental Meco.
This patented HAC technology was selected by the mining
company’s consulting engineer, Brown and Root.
Space limitations at the pebble-crushing circuit project dictated
the high-angrecycled asphalt crushers price used in mnle conveying route.
The two conveyors to be supplied used quartz crushing plant pricewill carry oversized copper ore
and dolerite pebbles, ranging from 15 mm to 65 mm, from quarry equipment crusher sandthe
existing automill circuits to the crushing plant.
The conveying angle of both conveyor belts is 45˚ with a lift
of 27,6 m over a length of about 64 m.
The capacity of each HAC is about 400 t/h with 37 kW drives at both
the top and bottom of the belts.
The HAC to be supplied is based on the sandwich principle, which
comprises two ordinary conveyor belts which ‘sandwich’
the conveyed materials between them.
“The additional force on the belts provides hugging pressure
to the conveyed medium by use of patented pressing mechanisms, so
that sufficient friction is supplied at the material-to-belt and
material-to-material interface,” explains Continental Meco MD
Doug Rome.
“This prevents the sliding back of material at a high
conveying angle as well as material degradation.” The units
are due to be commissioned by October.
