Twister AC07 is a semi-mobile, heavy-duty VSI crusher for use in tertiary and quaternary crushing applications. It is designed to produce “in spec”, high-quality cubically shaped aggregates and turn waste and flaky materials into quality cubically shaped aggregate as well as consistently graded crusher sand for use as bituminous sand, mortar sand, plaster sand or high-quality concrete sand. The low cost and high reduction crushing makes the Twister AC07 ideal for use in industrial mineral processing, pre-ball mill size reduction and glass recycling.

Twister VSI crushers use two variations of VSI crushing. The first is vertical shaft impact crushing where rock is fed onto a table type rotor which accelerates and then discharges the rock at high speed against steel anvils in the crushing chamber. The impact of the rock against the steel anvils induces fracture and breaks the rock. The second variation is called vertical shaft autogenous (VSA) crushing, where rock is fed into a multi-port rotor which accelerates and then discharges the rock at high speed against a rock filled crushing chamber. The impact of rock on rock induces fracture, breaks and shapes the rock. This unique crushing action provides low wear costs, superior products and high reduction ratios.

The Static Twister AC07 is mounted on a heavy-duty, free standing skid-frame and therefore does not require expensive foundations. It features a three-port modular rotor, 700mm in diameter, suitable to differing abrasive applications with throughput capacities varying from 30tph to 85tph. Additionally, it features a heavy-duty bearing housing, circular shaped outer crushing housing, single electric motor, hydraulic jack crusher housing lifting system and an open discharge chute with three position discharge. For this reason, the Static Twister AC07 is designed for rapid installation and easy integration with the rest the Pilot Crushtec modular range.
