Crusher Design Protects Users, Inspectors

Superior Industries Inc. launched the Valor Vertical Shaft Impactor (VSI), an impact-style bulk material crusher engineered to generate fines, eliminate unsound material and shape aggregate into a more cubic product, the company reported. Maximum operating rate is 800 tons per hour (t/h) (725 metric t/h), and maximum feed size is 8 inches (203 millimeters [mm]). The VSI is equipped with a cartridge style, right angle pinion gearbox, which allows for a safer deck-mounted motor arrangement and simplifies access to the drive and its components. A hydraulically powered lid allows for safe and easy access to the crushing chamber. A combination of automatic and manual safety interlocks protects maintenance inspectors. An autogenous rotor design promotes rock on rock crushing, which extends the life of many internal parts.
