Page 40 of 75 ROCK products • May 2018 • 39 Screen Machine The CST Cone Crusher is a large, track- mounted, portable crusher plant designed for secondary crushing of hard rock into cubical sizes. Mount- ing a heavy built "quarry duty" cone crusher on a wireless remote controlled track-mounted plant is rare and the placement of a shaker screen to pre- screen the fines out prior to entering the crushing chamber is unique. This feature increases overall production and significantly reduces wear costs. Features include: • Crusher: – 51-in. (1.3m) "quarry duty" standard head cone crusher. – Hydraulic tramp relief and hydraulic adjustment. • Screen: – Single deck 5- x 7-ft. (1.54- x 2.1-m) Stedman Stedman multi-row cage mills pulver- ize, grind, crush and/or mix abrasive and non-abrasive materials – wet, sticky or dry. The cage mills offer: • Fine, uniform grind up to 240 tph. • Reversible for extended wear life. •  Single-, two-, four-, or six-row cage assemblies are available. •  Optional heaters and air cannons are available to reduce buildup of wet and sticky materials. •  A quick-opening housing pro- vides minimum downtime during maintenance. •  Cage inspection requires about five minutes, complete change-out in as little as one hour. •  Aglime, coal, fertilizer, salts, potash, corn, aluminum dross, grains and gel- atin applications. • Full-scale toll processing and testing available. Stedman Machine Co., Superior Industries Superior offers 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 their 2015 acquisition of Clemro West- ern. After collecting customer feedback, Superior engineers redesigned the unit and added a number of new features. According to the manufacturer, the Lib- erty 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 installa- tion. Other unique features include pitman toe protection. This replaceable component offers an insurance policy if wearing occurs in the pitman fabri- cation. 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. Liberty jaw crushers are manufactured in feed openings of 18- x 36 in. to 36- x 48 in.
