Superior Industries Inc. recently unveiled a new machinery solution for crushing applications called the Liberty Jaw Crusher. Functioning as a primary crusher, the unit compresses material in stone, concrete, asphalt and ore applications.
Superior acquired the original design in its 2015 acquisition of Canadian-based Clemro Western. After collecting customer feedback, Superior engineers redesigned the unit and added a number of new features.
According to the manufacturer, the Liberty Jaw Crusher is engineered with an aggressive nip angle that maintains the machine’s ability to consistently grab and process material at a high level of efficiency. Additionally, a set of integrated lifting points are designed into the jaw dies for safe replacement or installation.
Another unique feature of the Liberty Jaw Crusher is pitman toe protection. This replaceable component offers an insurance policy if wearing occurs in the pitman fabrication. Furthermore, the unit’s motor is frame-mounted, allowing a smaller footprint and freeing up deck space for maintenance. More maintenance time is freed with the addition of hydraulic tensioning system and hydraulic wedge adjustment.
Superior’s Liberty Jaw Crushers are manufactured in feed openings of 18 in. x 36 in. to 36 in. x 48 in.
The company also debuted its new patent-pending Valor Vertical Shaft Impactor (VSI). The VSI is Superior’s second equipment solution for crushing bulk materials after launching the compression style Patriot Cone Crusher in late 2015. Impact style crushers, like the Valor VSI, produce a more cubically-shaped product.
Incorporating criteria from several of its existing customers, Superior said its engineers produced a stronger, safer and more convenient design. For example, the VSI is equipped with a cartridge style, right angle pinion gearbox. This allows for a safer deck-mounted motor arrangement, which also simplifies access to the drive and its components.
In addition, a hydraulically-powered lifting lid allows for safe and easy access to the crushing chamber. Maintenance inspectors are also protected by a combination of automatic and manual safety interlocks. Thirdly, an innovative autogenous rotor design encourages more rock on rock crushing, which greatly extends the life of many internal parts.
Superior manufactures models of its new Valor VSI for rates up to 800 tph (725 mtph) and maximum feed sizes up to 8 in. (203 mm).
