Metso’s new VSI Orange Series Rotor ENSURES MINIMUM DOWNTIME

O perational uptime plays a key role in today’s crushing operations where maximising productivity and reduc- ing the cost per ton are paramount. T meet these challenges, Metso has developed the Orange Series Rotor for vertical shaft impact (VSI) crushers. With the new rotors productive uptime can be increased sub- stantially through longer parts lifetime and faster service. The new Metso Orange series Rotor com- ponents have been reconfigured with built- in possibility for easy interchange, thus maximising wear life. The change-out of primary components through the service door has been improved. With the Orange Rotors, maintenance is made easy by reducing the total number of wear parts by 30% and the total number of components by 25%. This is achieved by integrating several components and using less fixing points. Hard-facing during main- tenance is no longer required.

The increase in wear parts life with these components is significant. The results of tests conducted on the new primary com- ponents in real quarry operations show that in most cases, there has been an enhanced wear life which for example has shown a 30-35% increase in tip life. In quarry operations, the extended lifetime will provide the operator significantly in- creased operational time with fewer inter- vals between wear parts changes. In tip and cavity wear plates replacement, the actual servicing time can be cut by more than half, due to simplified retaining bar fixing. The Orange Series Rotor was designed with the busy operators of the older model of Barmac VSI crushers in mind. The Orange Series Rotor can be fitted, without any modifications to all VSI models that accept the following rotors: 690 DTR, 840 DTR, and 990 DTR. b
