Metso has developed the new Orange series rotor for vertical shaft impact (VSI) crushers, saying that with the new rotors productive uptime can be increased substantially through longer parts lifetime and faster service.
“The new Metso Orange series rotor components have been reconfigured with a built-in possibility for easy interchange, thus maximising wear life. The change-out of primary components through the service door has also been improved,” says Metso. The total number of wear parts has been reduced by 30% and the total number of components by 25%, achieved by integrating several components and using less fixing points. “We have tested the new primary components in real quarry operations, achieving in most cases greatly enhanced wear life. For example, the tip life was increased by 30-50%,” says Tuomas Takalo, Metso’s product manager for Barmac VSI crushers.
“In quarry operations, the extended lifetime will provide the operator significantly increased operational uptime. Fewer intervals between wear parts changes will clearly increase the total capacities produced.”
The new series rotor was designed with the busy operators of the older model of Barmac VSI crushers in mind, and can be fitted, without any modifications, to all VSI models that accept the following rotors: 690 DTR, 840DTR and 990DTR.
