Excellent Products

Twirl VSI are machines that use autogenous rock-on-rock crushing to crush materials using a rotor that spins at high velocities to eject the feed material and create an impact with a rock lining, creating rupture along the existing microfractures in the rock. Our machines are purpose built and constructed to provide the user with great value in terms of maintenance and safety while decreasing the operating cost for the end user.

KNOW MORE

Rock on Rock Crushing

Twirl VSI's use a conventional 3-port closed rotor which can provide excellent shape to the material using high velocity impact crushing

Rotor Bypass

Openings are provided in the feed box to allow bypass of material up to 50% to allow increase in capacity. Any bypass will affect other parameters like shape/cubicity or liberation

Roof Lifter

Twirl VSIs are equipped with easy roof lifter hydraulic jack to ensure maintenance inside the crushing chamber

Easy Rotor Inspection

For quick inspections of the rotor, an inspection door is provided to easily check the wear of the rotor tips
