Vertical shaft impact (VSI) crushers offer reduced operating costs and increased production of saleable material.
Sandvik says its VSI crushers use the rock-on-rock crushing technique, which results in consistent product gradation and low contamination rates. Other features include reduced operational cost per ton, quick and easy replacement of wear parts, reduced out-of-balance forces, and excellent product shape.
Trio’s TV range of VSIs are configured to suit specific production requirements, enabling a combination of assemblies to be custom assembled for each application using interchangeable crushing chambers, rotor diameter, rotor type, and drive configuration. Each assembly is fully interchangeable.
Cemco says its Turbo 80 mid-size VSI crusher can be equipped to operate from 100 to 275 tons per hour with a maximum feed size of 2.5-inch material. Components that require routine maintenance are easily accessible; major servicing can be done in less than an hour. The drive system’s filtered oil lubrication system increases crusher life.
The Barmac VSI from Metso uses rock-on-rock crushing action to transform low-grade material into premium aggregate products. The company says the high-velocity impact crushing improves the soundness and shape of the stone, reduces product moisture, and eases the screening operation.
Stedman says its V-Slam Model VS-88 VSI features innovative housing and rotor designs; an easy-access, low-profile split swing lid; higher operating speed for finer grinding; and a 500 ton-per-hour capacity. A hydraulic drive offers variable mill speeds.
