Grinding developments from Outotec
Outotec says two recently released grinding products are designed to improve mill performance and improve upon previous technology.
Outotec said its hydraulic Inching Drive is an auxiliary drive designed to deliver safe and efficient mill installation and boost maintenance productivity and improve equipment safety.
The drive can rotate a mill in either direction during maintenance operations. The drive system consists of a planetary gearbox powered by a hydraulic drive motor.
Outotec said its portability makes it applicable to numerous mills, therefore fewer Inching Drives are required in a multi-line plant.
The joystick control allows for variable speed mill rotation, enabling precise mill positioning during installation and maintenance. The captive key interlock prevents operator bypass and ensures safety of personnel and equipment.
The Outotec Barricade seal is designed to solve issues surrounding effective sealing of grinding mill main bearings.
The design incorporates several protective properties. The Barricade seal replaces and improves these older seal arrangements with its unique design incorporating uniform lip tension, enhanced seal stability and provides superior sealing performance.
The Barricade arrangement is now standard supply for all new Outotec mill installations. It can also be retrofitted to many existing mills, improving safety, reducing environmental infringements and improving bearing lubricant quality.
