•BRU Horizontal screens
•BRU Banana screens
•VSW high frequency dewatering
•UHS medium or high freq. dewatering
•LVT screens
•Circular motion screens
•New Developments
Ludowici Screen Range
•Used for applications such as sizing, separation and dewatering
•Used in the coal, gravel, sand and mineral industries
•Available in single, double and triple deck configuration
•Various screen panels options
•(poly, wedge wire, plate)
•Single or Dual exciter 900-980RPM
BRU Horizontal Screens
BRU Banana Screens
•Used for applications such as sizing, separation &
media recovery
•Various screen panels options (poly, wedge wire,
plate)
•Size up to 4.2m wide x 9.15m long
•Increased capacity (by 50%) due to early
stratification & reduced bed depth
•High G Force provided for increased capacity
• Anti-abrasion, rubber lined cross beams• Cross beams made from UC section, no bolt holes ensuring no
liquid can enter• Stringers are bolted not welded onto brackets allowing quick
replacement• All welded components are fully stress relieved• Feedbox is designed to be an integral part of the screen,
eliminating the ‘cantilever’ effect of a bolt-on feed box
Benefits of BRU Screens
VSW High Frequency Screens
•Used for applications such as dewatering of fine coal or
mineral ores
•Inclined linear motion
•Capacity up to 60 - 70tph of fine material
•Suitable to use poly or wedge wire panels
•Operates at high frequency of approx 1430RPM
UHS Medium to High Frequency Dewatering Screens
•Used for applications such as
dewatering of fine coal, trash removal,
loaded carbon recovery and general
slurry process
•Horizontal linear motion
•Can be supplied at medium or high
frequency (970RPM or 1430RPM)
•Quietest performance
•Clip-on deck system with no sub-frame
•Fully Huck-bolted construction
•Screens are lighter which reduces the support steelwork and
electrical supply required
LTV Screens
•CA – standard duty circular motion
screens using spring loaded
counterweights instead of motors
•CB – heavy duty circular motion screens
which are used in harder applications
such as hard rock and use spring loaded
counterweight mechanisms rather than
motors
Circular Motion Screens
•Electro-mechanical drive with out-of-
balance motors which are self-
synchronising to provide linear motion
•Nominally 10mm stroke which prevents
build-up of material on the feeder pan
•Can be foot mounted or cable suspended
UF Pan Feeders
•Driven by ‘HE’ series gearboxes from our
BRU screen range
•Counter-rotating flywheels provide linear
motion
•Grizzly bars manufactured to client
specifications from high wear resistant
materials such as Bisalloy 500 (quenched
and tempered steel) or Domite capping (a
laminated, abrasion resistant wear product
at 200 BHN)

Ludowici RC Technology offers the latest in fine particle Beneficiation.
Our Reflux Classifier, used in coal and
minerals processing is a fluidised bed
separator incorporating a lamella settler
and autogenous dense-medium
separator. It comprises inclined lamellar
channels that deliver superior hydraulics
compared to conventional
technologies.

Mining and Quarrying
Screen Types Available
•Modern mining and quarrying screens use a variety of materials and fastening methods in their plant screens:
•Crimped wire ModularProfile [Vee, wedge] wire Cross TensionedPolyurethane BoltedRubberMetal Plate and Castings
Ludowici supplies all of the above, in all combinations:
a ‘One Stop Screen Shop’
Screen Types
Crimped Wire – Cross Tensioned
•Staple product for the quarrying industry
•Excellent open area, robust construction
•Apertures from 2 to 100 mm available,
in varying wire gauges

‘Next Generation’ Crimped Wire Screens
As part of Ludowici ongoing commitment to
continuous improvement for industry,
second, third and fourth generation wire
screen mats have been designed and
developed
Screen Types - Continued
‘Next Generation’ Crimped Wire Screens
- Continued
•‘Agavibe’ – Second generation, non blinding
wire screen mat.
•‘Polyvibe’ – third generation, in flow wire
replaced with polyurethane
Screen Media Types
Media Type – Wedge Wire [aka Profile Wire]:
•Stainless steel wire, 304 and 316 typ
•Excellent open area
•High efficiency of operating screens
•Used mostly for fine apertures
[< 1mm typ]
•Rigid, inflexible. Modular or clamped.
Polyurethane Modular System Advantages
• Versatility of polyurethane permits design of
tailor made, fit for purpose applications for
any unique site specific conditions.
• Exotic apertures, exotic polymers, special
panel designs and attachments impossible
to incorporate with any other media or
fixture methods are possible.
• Overall, significantly cheaper total cost of
screening than metallic media [in terms of $
/ tonne]
Polyurethane Modular Systems - General
• Modular screening systems have enjoyed
much success in the mining industry for the
last decade.
• Large, cumbersome, cross tensioned steel
wire screen mats have been replaced with
smaller, easier to install panels made from
steel reinforced abrasion resistant
polyurethane.
Polyurethane Modular System Advantages
• Installation requires no special skills or tools
• Panels are lighter and smaller, therefore faster
and safer to install.
• Polyurethane’s abrasion resistance gives at least
5 - 7 times increase in wear life over crimped wire
• Better plant availability and utilisation
• Flat deck gives better distribution of feed than
cross tension, better use of screen deck, better
screening
Modular Systems - General
• Panels are usually 2’x1’ or 1’x1’
• Made from polyurethane with
internal steel reinforcement
• Usually use interference fit type
locking, either pins or rails.

Modular Systems – Ludowici’ patented Ludodeck PIPO Two
• An intermediate rail type system
• Two components, panel and the
rail [other systems have more
components]
• Panels have female sockets, lock
onto the rail male
• Remove via mallet / screwdriver
Modular Systems – Ludodeck PIPO Two Advantages
• Once rail installed, Ludodeck
PIPO Two has less consumable
components than other
systems[no pins to carry stock
or get lost in sumps].
• Poly – Poly grip, stronger than
pin type systems. Robust design
panels
• Screen steel is protected, holes
don’t get ‘out of round’
Modular Systems – Ludodeck PIPO Two [Panel Removal]
• Once the intermediate rail is installed,
panel removal requires no special skills,
training or tools
• Able to be undertaken by any site
personnel
• Remove via mallet and screwdriver
Modular Systems – Ludodeck PIPO Two[Panel Replacement]
• As before, once the intermediate rail
is installed, panel installation is able
to be undertaken by any site
personnel
• Once the rail is cleaned, install via
mallet
Ludodeck – Multi Open Area
Ludodeck PIPO Two – Advantages - Cont
• Ludodeck PIPO Two + punched plate, as another ‘hybrid’ option
• High open area heavy duty applications
