SCREENING AND WASHING

Washing and screening go hand in hand across a whole
range of mining applications, from iron ore to silica sand
and coal. Paul Moore reports on some new technologies
and innovations
odularisation and portability are
becoming ever more important in the
industry for smaller mines that want to
be agile in their production; and this applies to
screening and washing equipment as much as
any other area.
Haver & Boecker, one of the leading
equipment manufacturers and solutions
provider in aggregates and mining applications,
recently introduced the skid-mounted Hydro-
Clean™ 1000 Wash Plant as a complete
solution. In addition to a Hydro-Clean 1000
washing system combined with a Tyler L-Class
vibrating rinse screen, Haver & Boecker now
offers semi-portability by mounting the
complete system on a custom skid structure.
“The opportunity to purchase the three
components together saves operations months
of time they would have spent on designing and
building a skid structure for a wash plant. The
new package delivers maximum serviceability in
a small footprint.”
“We’re always looking for ways to solve our
customers’ problems and improve their
productivity and efficiency,” said Karen
Thompson, President of Haver & Boecker Canada.
“By offering the Hydro-Clean 1000 Wash Plant,
we’re saving producers from spending extensive
time on engineering and manufacturing a
structure for a wash plant. This gives them an
opportunity to focus their time and money on
improving profits elsewhere in their operations.”

Haver & Boecker combines the Hydro-Clean
1000, a single-deck, linear-stroke, 6-by-16-ft
Tyler L-Class horizontal vibrating rinse screen
and a skid structure to create the compact wash
plant. The system processes as much as 200 t/h
of sellable product with its short retention
times; using minimal water and power. During
the cleaning process, the washed material
works its way down the HC1000’s drum and exits
onto a discharge conveyor that leads to the L-
Class wash screen. The vibrating screen removes
any remaining dirt or clay still on the stone as it
fractionates the material. “Haver & Boecker
engineers drew on their extensive experience to
design and build a skid structure perfectly
suited for the semi-portable system.”
Taking feed material as large as 6 in (150 mm)
into its 40-in vertical drum, the Hydro-Clean
1000 employs 2,000 psi high-pressure nozzles,
rotating at 90 rpm, to remove silt and clay
particles as small as 63 microns from mineral
mixtures. The Hydro-Clean’s high-pressure
nozzles effectively clean deleterious material
from aggregates, recycled materials and other
minerals.
The wash plant’s other major component, the
L-Class vibrating screen, uses a double-shaft
overhead drive system, with direct-mounted
motors, to provide multiple speed and stroke
combinations in a compact design. With a
horizontal screen, material spends more time on
the deck for optimal cleanliness.
The HC1000 Wash Plant includes
serviceability features for maximum
convenience and safety. Haver & Boecker
manufactures the plant with stairs, eliminating
the dangers of carrying parts and tools up
ladders. In addition, mechanics can easily use
the plant’s catwalks and platforms to reach
service points, such as spray nozzles. Haver &
Boecker says it can engineer wash plants to
customer specifications by, for example,
including a different size or type of vibrating
screen, more decks or a different Hydro-Clean
model.

can produce 550 t/h of washed materials from a
single machine when it unveiled its new sand
