This used Metso B9100SE Quarry Crusher is a crusher — sometimes referred to as a rock crusher or impact crusher — designed for high-reduction size reduction of rock, aggregate, and mineral materials across quarrying, mining, and construction applications. Metso is a well-established Finnish manufacturer of heavy equipment for the mining, aggregates, and process industries, with a long track record in crushing, screening, and minerals processing machinery.
This particular machine is a Barmac VSI (vertical shaft impactor) crusher, an autogenous unit that combines crushing and grinding action in a single pass. Unlike conventional compression crushers, the autogenous VSI design uses material-on-material impact to break rock, which reduces wear on metal components and makes the machine well suited to processing competent, abrasive, friable, or sticky materials. It is positioned as a third or fourth stage reduction unit in a crushing circuit, operating downstream of primary and secondary crushers to produce finely graded output.
The machine was manufactured in 2019 and has accumulated only 2,000 working hours, placing it in strong used condition relative to its age. It is currently located in China.
In terms of application, the seller describes this crusher as a proven and cost-effective solution for producing concrete aggregate, asphalt chips, and manufactured sand. Its capacity to reduce the F(80) — a standard measure of feed particle size distribution — and to improve mineral liberation also makes it suitable for preparing mill feed, sinter feed, and material for heap leach operations, broadening its relevance beyond quarrying into mineral processing environments.
