NORDVIK VSI Crusher PB Series

• Deep rotor technology — The deep-chamber rotor processes more material per revolution, maximizing capacity per kilowatt installed.
• Cascade gradation control — An adjustable bypass cascade fine-tunes fines content and product shape without changing the rotor or stopping.
• Rock-on-rock crushing — Material crushes against itself in the chamber, giving superior cubical shape with minimal metal wear.
• Advanced automation — Vibration and load monitoring protect the machine and hold peak performance around the clock.
• Low operating cost — Wear is concentrated on inexpensive, quick-change tip and plate sets — the lowest cost per tonne of sand.
• Safety first — Designed to the latest safety requirements with interlocked inspection covers and safe lifting points.

The PB VSI accelerates feed material through a high-speed deep rotor and ejects it against a rock-lined crushing chamber. Rock-on-rock impact fractures particles along their natural fissures, producing a cubical, well-graded product. A portion of the feed can bypass the rotor as a controlled cascade into the chamber, letting the operator fine-tune capacity and gradation without changing rotor speed.

The PB's deep-chamber rotor accepts a higher material volume per revolution than shallow rotors, converting installed power directly into throughput. Combined with rock-on-rock chamber action, it delivers premium cubical product at the lowest wear cost in its class.

The adjustable cascade bleeds a controlled portion of feed past the rotor directly into the crushing chamber. Operators tune fines content and gradation on the fly — no rotor change, no stoppage — while integrated vibration and load monitoring keeps the machine inside its safe envelope.
