The first set of crusher drive motorbases manufactured by Crushing and Mining Equipment have reached a significant milestone, having been in operation for more than five years without faults.
The drive motorbases are in operation 24 hours a day at a West Australian iron ore mine, and have clocked up an estimated 35,000 hours since being installed. They were manufactured and installed as part of a drive upgrade at the site back in 2006, having operated untouched since then.
Crushing and Mining Equipment specially designed the units so that they could achieve constant belt tension for the full belt life, with tension maintained within a few percentage points as the belts stretched.
In addition, the design of these crusher drive motorbases has allowed for belt changes to be performed without the need to realign pulleys, and includes a range of safety features designed to protect the motor and operator.
Crushing and Mining Equipment Service Manager, Sandy Risely, recalls installing the motorbases in 2006. He oversaw their installation with a previous employer, noting that "we expected the belt tension to be maintained, but what we didn't expect was the decrease in power draw during crusher."
The success of this first installation prompted Crushing and Mining Equipment to expand its range of heavy duty motorbases, so that now it can offer a motorbase to suit any application, regardless of motor size.
