New jaw crusher promises safer operation
An innovative jaw crusher has been introduced to the market by Astec Industries. Designed for demanding primary applications, the A50 is said to deliver durability and performance and includes new features for safer operation and maintenance.
Drawing on the company’s past jaw crusher models such as Pioneer, Telsmith and Osborn, this is the first in Astec’s new A-series line of jaw crushers.
“By bringing together the best engineering expertise and proven designs from across our legacy brands, we’ve created a machine that represents both our legacy and establishes a new benchmark in future jaw crusher design,” says Astec VP: product management Stephen Whyte.
The A50 jaw crusher features a keyed and bolted frame engineered to eliminate high-stress welded joints for enhanced structural integrity and long-term durability. The machine’s solid side plates have removed weak points and cutouts in the mainframe side plates, in a bid to boost reliability and add strength where required. A cast swing jaw with angled wear plate prevents material bridging and strengthens high-stress zones for improved performance under heavy loads.
Other features and benefits of the unit include longer liners with an improved nip angle to maximise material grip, reduce wear and increase crushing efficiency; interchangeable fixed and swing liners, which help to extend wear part life, simplify maintenance and lower operating costs; and patented interchangeable toggle assemblies with hydraulic and mechanical options to help eliminate heavy wedges and side plate cutouts for fast, safe adjustments and quick resets after an uncrushable event.
The A50 boasts reduced horsepower requirements and a stroke that delivers higher capacity, thanks to its high-inertia, heavy-duty flywheels. Specially-engineered rubber mounts isolate crushing forces, reducing the impact on chassis frames and mounting structures.
