More Asphalt produces more asphalt
single combination drying and mixing
drum in a counterflow configuration,
incorporating a long-nose burner.
“Our years of experience in designing,
building and operating these plants
allows Comar to customise each plant
to our individual customer’s particular
specifications,” says Comar director Ken
Basson. “As a 100% local company, we
also understand the demands of local
conditions, and build plants that maximise
uptime and productivity.”
The new plant includes six cold feed
bins for sand and aggregate and two
recycled asphalt pavement (RAP) bins
for fine and coarse fragment sizes. A
baghouse for catching dust particulate
emissions, as well as a state-of-the-
art motor control centre in a 12-metre
shipping container, are also key elements
of the new plant.
“The facility uses a higher quality fuel
than normal, providing better combustion
and less sulphur burn-off,” says De Wet
Dreyer, Comar operations manager.
“Among the benefits of this fuel choice is
longer bag life and reduced maintenance
costs for the overall operation.”
As a result, the plant complies
comfortably with new emission standards
on dust particulate levels, which require
that emissions do not exceed 50mg/Nm3.
A recent inspection of the plant confirmed
it was dealing well with the high production
volumes, showing little wear on the lifters
and also minimal wear in the bags, which
were operating highly efficiently.
The design provides for additional
loadout flexibility should the customer
require it, which allows a fourth product
to be discharged directly onto trucks,
while the three silos are filled. The scope
of work for the More Asphalt contract
included disassembling and removing the
company’s old plant before installation of
the new plant could begin.
Western Cape asphalt producer, More
Asphalt, has almost doubled production
capacity at its Tygerberg Valley site outside
Cape Town with a custom-built continuous
mix asphalt plant from Comar. The facility
impressed its owners by exceeding its
operating expectations and producing
100 000t in its first seven months.
According to Owen Peringuey, executive
director at More Asphalt, the manufacturing
of the plant went very smoothly, in line with
the set out plan and within the required
timelines. “It was a pleasure working with
a company as professional as Comar,” says
Peringuey. “They were able to design,
manufacture and commission what we
needed, and more.”
Comar’s team of experienced design
engineers, using modern software tools,
designed the 140 tonne-per-hour plant
to suit the customer’s constrained site
footprint. Space savings were achieved
through the design and installation of a
