The new Telsmith T300 Cone Crusher has been designed for maximum uptime and productivity while delivering 300-HP performance and a crushing capacity output range from 125 to 400 Mt/hr in tough or abrasive mining applications. Efforts have been made to lower operating costs and increasing safety, the T300 features a large clearing circuit allowing uncrushable material to pass. The T300 has serviceability features such as the six cylinder design, which is less than conventional units, still offers the largest crushing force available, as well as including a new patent-pending anti-spin feature that prevents head spin to extend manganese life. This is mounted on top of the machine for top-service access. The T300 is also designed to operate with pressure lubrication oil, eliminating the use of a gear box and a separate hydraulic circuit. The T300 also features the largest-in-class, patent-pending hybrid bearings. Unlike roller bearing machines, these large hybrid bearings offer both a static and dynamic lift – which results in far greater lift to efficiently carry the crushing forces. Also, hybrid bearings feature a washer and ramp design that replaces the conventional use of a socket, socket liner, and head ball – all of which typically require time-consuming removal when servicing the machine. The Telsmith T300 is also nitrogen-free and is engineered with a patented release system that eliminates the need for maintenance-intensive hydraulic accumulators. Other features include the patent-pending concave (bowl liner) retention system which consists of a specially-designed and positioned lip ring that centers the bowl and achieves retention without the use of hammers and other hand tools.
