Twister vertical shaft impact (VSI) crushers produce “in spec”, high-quality cubically shaped aggregates and sand that meets today’s demanding specifications in contracting, civil engineering and construction projects. Vertical shaft impact (VSI) crushers have been the backbone of the Pilot Crushtec International product line up for more than twenty years with the Twister crusher having established itself as a leader in vertical autogenous rock-on-rock crushing technology. With this rock-on-rock crushing principle that reduces expensive metal crushing parts, rock reduction and shaping can be achieved with low wear costs.
 
The Twister VSI static range - consisting of the AC06, AC07, AC208 and AC210 – has throughput capacities ranging between 10tph and 350tph. They are often used to 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 crushers ideal for use in industrial mineral processing, pre-ball mill size reduction and glass recycling.
 
Twister semi-mobile crushers are standard, heavy-duty crushers supplied complete and ready to run. They are mounted on skid-frames, do not require concrete foundations and are designed for rapid installation and easy integration with the rest of our product range. These tried and tested crushers are designed to handle the harshest conditions and toughest rock in all types of applications.
 
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 field-proven Twister VSI crushers are used all over the world in aggregate, industrial milling, recycling and mineral processing applications. With over 500 units in operation around the world, Twister VSI crushers are providing users with cost effective, high quality and high performance solutions for their tertiary and quaternary crushing requirements.
