The Astec Hydra-Jaw is a high-performance primary jaw crusher engineered to deliver reliable, high-capacity crushing across quarrying, mining, construction, and recycling applications. Combining proven jaw crushing technology with advanced hydraulic systems, designed to maximise uptime, simplify operation, and reduce maintenance, making it an ideal solution for demanding crushing environments.

Featuring hydraulic adjustment, automatic overload relief, and hydraulic chamber clearing, the jaw allows operators to quickly adjust the closed-side setting (CSS), recover rapidly from tramp events, and safely restart after power interruptions. Its heavy-duty construction, interchangeable jaw dies, and robust toggle system provide exceptional durability while reducing wear part inventory and operating costs.

Built to deliver consistent performance and ease of maintenance, the Astec Hydra-Jaw offers reliable primary crushing with the productivity and reliability required for high-output aggregate, mining, and recycling operations.
