Superior brings jaw crusher to market

Superior Industries Inc. unveiled a new machinery solution for crushing applications in 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 Superior, 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. In addition, a set of integrated lifting points are designed into the jaw dies for safe replacement or installation. Another unique feature is pitman toe protection. This replaceable component offers an insurance policy if wearing occurs in the pitman fabrication. In addition, the unit’s motor is frame-mounted, allowing a smaller footprint and freeing up deck space for maintenance, the company says.
