New Barmac VSI Orange-series rotor adds operational uptime and secures quick parts change
OPERATIONAL uptime plays a key role in today’s crushing operations, where maximizing productivity and reducing the cost per tonne are paramount. To meet these challenges, Metso have developed the new Orange-series rotor for vertical-shaft impact (VSI) crushers.
With the new rotors, productive uptime can be increased substantially through longer parts lifetime and faster service, say Metso.
The new Orange-series rotor components have been reconfigured with a built-in possibility for easy interchange, thus maximizing wear life. The change-out of primary components through the service door has also been improved.
With the Orange rotors, maintenance has been made easier by reducing the total number of wear parts by 30% and the total number of components by 25%. This has been achieved by integrating several components and using fewer fixing points. Moreover, hard-facing during maintenance is no longer required.
Describing the increase in wear parts life as ‘significant’, Tuomas Takalo, Metso’s product manager for Barmac VSI crushers, said: ‘We have tested the new primary components in real quarry operations, achieving greatly enhanced wear life in most cases. For example, the tip life was increased by 30–50%.’
He continued: ‘In quarry operations, the extended lifetime will provide the operator with significantly increased operational uptime. Fewer intervals between wear parts changes will clearly increase the total capacities produced.’
The change-out of primary components for the Orange rotor through the service door has been greatly improved, significantly reducing the time needed for 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,’ said Mr Takalo, who added that similar time savings can be achieved with other wear parts replacements.
The Orange-series rotor was designed with operators of the older model of Barmac VSI crushers in mind. The Orange rotor can be fitted, without any modifications, to all VSI models that accept the following rotors: 690 DTR, 840DTR and 990DTR.
