Cascade Feature
Designed for low service requirements, ease of lubrication and
continuous service, the Barmac will readily fit into any existing
or proposed crushing plant.
The Barmac B-Series VSI crusher uses a patented hydracascade
feed system to introduce a second stream of material, in a
controlled quantity, into the crushing chamber turbulence,
causing a supercharging of particle population within the
chamber, thereby improving the energy transfer between the
particles.
Mineral processing
The Barmac is an excellent third or fourth stage reduction unit,
combining a unique crushing and grinding action in a single
machine for the processing of virtually any competent, abrasive,
friable or sticky material.
The Barmac, with its high capacity and ability to produce finely
graded products such as mill feed, sinter feed or material for
heap leach operations, is an ideal machine to replace high cost,
inefficient crushing and milling equipment.
The addition of a Barmac crusher to an existing crushing circuit
can save considerable capital funds when increased production
is required from an existing milling circuit.
Quarrying
The Barmac crusher is a proven producer of top quality
aggregate products for asphalt paving, concrete aggregates
or specification sand. It crushes a wide range of materials and
will process hard, highly abrasive rocks as a matter of course.
The high velocity impact crushing achieved in a Barmac
improves the soundness and shape of stone, reducing product
moisture and easing the screening task while producing
superior products at a minimum cost.
Barmac VSI features
• Competitive capital cost, especially when compared with
conventional crushing equipment
• Low service and maintenance requirements along with
minimum operating and wear costs
• Rock-on-rock technology minimises wear part requirements
• Quick and easy installation. Crushers require minimum
support structure and are also ideal as portables and mobiles
• Ability to control product grading, maximising or minimising
fines production
• Produces a product of superior cubical shape

Hydracascade offers external hydraulic adjustment of the
cascade ratio while the crusher is operating, for accurate control
of product specification and grading. Adjustment can be hand
operated or be fully integrated into automated plant systems.
Hydracascade provides greater flexibility and control of the
crusher discharge product – flexibility that can accommodate
changes in feed specification and control that provides total
management of product quality and fines content.
• Up to 100% more production depending on the application
• Maximum use of available power without fear of motor
overload
• Optional remote or automation of the cascade and rotor
feed control system
• Productivity advantages gained by cascade crushing

A new era in rock-on-rock crusher design
The User-Friendly VSI crusher
The Barmac B-Series VSI provides higher capacity for a given
motor size, easier servicing and reduced operating costs.
Benefits have been achieved by an improved machine design,
including a new hopper configuration, radical crushing
chamber variations and the development of new rotor
technology.
Service time has been drastically reduced with complete access
to all rotor parts, simplifying wear part replacement procedures.
VSI Operational Control System (VOCS) Option
The VOCS has been designed to provide the Barmac operator
with constantly updated information on the operating
condition of the vital mechanical components of the
equipment. Three areas are monitored: Vibration caused by an
unbalanced rotor, bearing cartridge running temperature, and
motor winding temperature.
Automatic Crusher Regulation (ACR) Option
ACR is the tool for maximising crusher capacity and
effectiveness. ACR ensures consistent and efficient operation
of the Barmac where correct crusher operation has its most
significant influence – the final product quality and plant
energy consumption. ACR monitors and controls crusher load
and cascade levels. Internal control procedures ensure that
after initial calibration and setting of the crusher and feeder,
ACR will continuously adjust the crusher to maintain optimal
conditions.
Roof Lifter (RL) Option
The roof lifter has been developed to provide quick and easy
access to the internal workings of the Barmac. This allows for
rapid rotor and wear part changes and minimises down time
while maximising availability. The simple and reliable design
of the roof lifter means only one person is required for
operation, while a crane is not needed at all.
Automatic Lubrication Option
The Barmac automatic lubrication system ensures an accurate
metered flow of lubricant to the crusher bearing cartridge
through the use of an electric motor driven grease pump and
divider valves. Three divider valves are factory set to supply
the correct quantity of grease to the crusher bearing cartridge.

Applications
Nordberg Barmac B-Series VSI – An Established Track Record
Nordberg Barmac B-Series VSI crushers are operating in
aggregate and mineral processing installations around
the world with an established track record of cost savings,
durability and unmatched performance.
Metso Minerals has the technology and experience in applying
and servicing the Barmac crusher across the globe in an
extensive variety of applications, processing a diverse range
of materials.
The unmatched producer of superior concrete
and asphalt aggregate
The Barmac combines high velocity impact crushing with high
pressure attrition grinding to produce high volumes of cubically
shaped product. Continuous control of the product shape and
gradation provides a product which meets the size distribution
required.
A proven producer of quality manufactured
sand
Superior particle shape and consistent gradation are a direct
result of the rock-on-rock principle of the VSI crusher. Impact,
grinding and abrading within the crusher simulates the action
of nature, eroding the particles to a cubical shape.
The perfect premill crusher to improve milling
circuit performance
The Barmac reduces power requirements and increases mill
capacity by reducing the top size and increasing the fineness
of the mill feed. Mill liner life is increased by providing a finer
mill feed, allowing the use of smaller mill balls to achieve the
required size reduction.
The producer of fine products for the industrial
minerals industry
The Barmacs crushing action gives a product with a large
surface area which gives increased recovery of the desired
mineral. The free impact reduction will preferentially crush a
more friable mineral when separating a desirable product from
a waste material.
The only viable crusher in extremely abrasive
materials
The rock-on-rock crushing principle of the Barmac minimises
metallic wear resulting in low maintenance and wear costs.
The low wear of internal components ensures extremely low
contamination of the product through wearing metal parts.
