The right VSI crusher for your project

Vertical shaft impact crushers, better known as VSI crushers, are typically used as third and fourth stage crushers in a number of applications relevant to the South African mining and construction industry. Pilot Crushtec International, a leading supplier of mobile and semi-mobile crushing and screening solutions holds the key to a range of high quality, cost effective VSI crushers – namely, the Twister VSI range.

What does the Twister VSI crusher do?

Pilot Crushtec International’s range of heavy duty Twister VSI crushers are designed to crush a wide variety of rocks and minerals using either rock-on-rock or rock-on-steel crushing principles. Twister VSI crushers are used to crush material all over the world, from aggregate and industrial milling to recycling and mineral processing applications.

The difference between VSI and VSA crushing

The Twister range utilises two variations of VSI crushing – vertical shaft impact crushing and vertical shaft autogenous crushing.

Vertical shaft impact crushing (VSI)

Rock-on-steel impact: rock is fed onto a table-type rotor which accelerates at high speeds in order to fling the rock against the steel anvils located in the crushing chamber; therefore, fracturing the rocks as they impact against the steel.

Vertical shaft autogenous crushing (VSA)

Rock-on-rock impact: rock is fed into a multi-port rotor which accelerates, discharging the rock at a high speed against a rock-filled crushing chamber. The impact fractures and breaks the shape of the rocks. This crushing action allows for low wear costs and high reduction ratios.

Mobile and semi-mobile crushers

Mobile crushers

The TwisterTrac range is a fully mobile diesel hydraulic VSI crusher with remote control functionality and tracking. A world-leading mobile crushing solution like the TwisterTrac is ideal for applications in the mining, construction and civil engineering industry as it can be used on its own or integrated into mobile crushing plants. The TwisterTrac also features variable rotor speeds and has a throughput capacity of up to 300tph.

Semi-mobile crushers

Pilot Crushtec International supplies processing plants all over Africa with the finest Twister semi-mobile crushers – a heavy-duty crusher mounted on skid-frames. Semi-mobile crushers are ideal as a complete, ready to run crushing solution as they don’t require a concrete foundation and are designed for rapid, easy installation and integration with other Pilot Crushtec product ranges. These powerful crushers are designed to handle the toughest types of rock in a number of harsh applications.
