   The Barmac B7100 autogenous VSI crusher is anexcellent third or fourth stage reduction unit,combining a unique crushing and grinding action in asingle machine for the processing of virtually anycompetent, abrasive, friable or sticky material. The crusher is a proven, cost effective solution to meettoday's demands for concrete aggregate, asphaltchips and manufactured sand. The crusher's ability to reduce the F(80), improvemineral liberation and reduce energy consumptionmakes it ideal for the production of mill feed, sinterfeed or material for heap leach operations, etc. Application Specifications Nordberg Barmac B7100 VSI Crusher Technical DataCascade Feature  The Barmac B7100 VSI crusher uses a patentedhydracascade feed system to introduce a secondstream of material, in a controlled quantity, into thecrushing chamber turbulence, causing a superchargingof the particle population within the chamber, therebyimproving the energy transfer between the particles.Hydracascade offers external hydraulic adjustment of the cascade ratio while the crusher is operating, foraccurate control of product specification and grading.Adjustment can be hand operated or be fullyintegrated into automated plant systems.Hydracascade provides greater flexibility and control of the crusher discharge product – flexibility that canaccommodate changes in feed specification andcontrol that provides total management of productquality and fines content.  The nominal capacities shown in thistable will alter with changes to theselected operating parameters of theB7100 crusher and variations in thephysical characteristics of the feedmaterial.
