Cascade Feature

The Barmac B-Series VSI crusher uses a patented hydracascadefeed system to introduce a second stream of material, in acontrolled quantity, into the crushing chamber turbulence,causing a supercharging of particle population within thechamber, thereby improving the energy transfer between theparticles.

Hydracascade offers external hydraulic adjustment of thecascade ratio while the crusher is operating, for accurate controlof product specification and grading. Adjustment can be handoperated or be fully integrated into automated plant systems.

Hydracascade provides greater flexibility and control of thecrusher discharge product – flexibility that can accommodatechanges in feed specification and control that provides totalmanagement of product quality and fines content.

• Up to 100% more production depending on the application

• Maximum use of available power without fear of motoroverload

• Optional remote or automation of the cascade and rotorfeed control system

• Productivity advantages gained by cascade crushing

The complete range of Nordberg Barmac B-Series VSIcrushers incorporate rock-on-rock crushing technologythat has revolutionised the aggregates and mineralsindustries worldwide.

The Barmac rock-on-rock crusher offers the modern operatorproduct grading control by optimising numerous variables:

• Variation of rotor speed

• Choice of crushing chamber cavity rings

• Adjustment of cascade feed ratio

• Selection of rotor diameters

Designed for low service requirements, ease of lubrication andcontinuous service, the Barmac will readily fit into any existingor proposed crushing plant.

Mineral processing

The Barmac is an excellent third or fourth stage reduction unit,combining a unique crushing and grinding action in a singlemachine for the processing of virtually any competent, abrasive,friable or sticky material.

The Barmac, with its high capacity and ability to produce finelygraded products such as mill feed, sinter feed or material forheap 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 circuitcan save considerable capital funds when increased productionis required from an existing milling circuit.

Quarrying

The Barmac crusher is a proven producer of top qualityaggregate products for asphalt paving, concrete aggregatesor specification sand. It crushes a wide range of materials andwill process hard, highly abrasive rocks as a matter of course.

The high velocity impact crushing achieved in a Barmacimproves the soundness and shape of stone, reducing productmoisture and easing the screening task while producingsuperior products at a minimum cost.

of the Barmac where correct crusher operation has its mostsignificant influence – the final product quality and plantenergy consumption. ACR monitors and controls crusher loadand cascade levels. Internal control procedures ensure thatafter initial calibration and setting of the crusher and feeder,ACR will continuously adjust the crusher to maintain optimalconditions.

Roof Lifter (RL) Option

The roof lifter has been developed to provide quick and easyaccess to the internal workings of the Barmac. This allows forrapid rotor and wear part changes and minimises down timewhile maximising availability. The simple and reliable designof the roof lifter means only one person is required foroperation, while a crane is not needed at all.

Automatic Lubrication Option

The Barmac automatic lubrication system ensures an accuratemetered flow of lubricant to the crusher bearing cartridgethrough the use of an electric motor driven grease pump anddivider valves. Three divider valves are factory set to supplythe correct quantity of grease to the crusher bearing cartridge.

A new era in rock-on-rock crusher design

The User-Friendly VSI crusher

The Barmac B-Series VSI provides higher capacity for a givenmotor size, easier servicing and reduced operating costs.

Benefits have been achieved by an improved machine design,including a new hopper configuration, radical crushingchamber variations and the development of new rotortechnology.

Service time has been drastically reduced with complete accessto all rotor parts, simplifying wear part replacement procedures.
