With its processing capabilities of up to 600tonnes/hour, and designed with a 34-inch x 50-inch opening, the H3450 is the latest addition to Telsmith’s Hydra-Jaw Series.

The same as prior models, the H3450 is engineered with a hydraulic toggle that reduces downtime and maintenance requirements, and lowers operating costs with fast, safe hydraulic chamber clearing, and tramp iron overload relief with auto resets. For significant operating cost savings, the H3450 is designed with interchangeable swing and stationary jaw dies. Operators need to stock only one type of jaw die, and that die is reversible top to bottom and left to right.

According to Telsmith, an Astec Industries company, the H3450’s hydraulic control panel allows adjustments to be made in moments. No spring adjustment or tools are needed. Compared to traditional shim adjustments, Telsmith says this eliminates an hour or more of downtime, allowing for frequent adjustments if necessary. By maintaining the optimum feed size for the next stage of crushing, plants gain greater productivity and improved quality control.

To prevent costly downtime and repairs, the overload relief system protects the crusher from tramp metal or other uncrushable material. The system senses an overload condition, allowing the crusher to automatically open and the materials to pass – followed by an automatic reset to the assigned setting.

Telsmith says there is no need to dig out the crusher after an emergency stop or power outage. Via push-button controls, the hydraulics crush any material that remains in the chamber, preventing oversized material from passing onto the product belt.
