RUSSELL Elevating Platforms – the only ‘built for purpose’ elevating equipment to enable quicker and safer bolt removal on Grinding Mills.
Improving maintenance efficiency by reducing the number of inchings during relining and retorquing, RUSSELL Elevating Platforms also ensure site crew safety by providing a strong, stable and flexible operating platform.
A Grinding Mill’s worn liners can only be accessed ‘Mill shell segment’ by ‘Mill shell segment’.
As one segment of liner bolts are completely removed using THUNDERBOLT Recoilless Hammers from the outside of the Mill Shell during “Knocking In”, the Mill Relining Crew who operate the Mill Relining Machine then collect the segment’s worn liners which have fallen to the Mill charge.
These worn liners are safely picked up using RME O-ZONE Liner Lifting Tools, attached to the Mill Relining Machine’s grapple head. The worn liners are then and placed onto the Mill Relining Machine’s Liner Transport Carriage for transport out of the Mill (“Mucking Out”).
In 2004, RME engaged the services of ex-Escondida Concentrator Manager, Stephen Kittel, a metallurgist who undertook detailed time and motion studies of RME’s Mill Relining System in action at a range of sites world-wide. These studies revealed new opportunities for RME’s Mill Relining System.
One of the insights from the Kittel Time and Motion Studies was the time taken to move the
THUNDERBOLT from liner bolt to liner bolt during ‘Knocking In’. This particular insight precipitated the invention of the THUNDERBOLT Moil Axis Guide device known as the T-MAG, and ultimately to RME’s RUSSELL Elevating Platforms, acknowledged as a Grinding Mill Relining Crew must.
THUNDERBOLT Recoilless Hammer raise/lower function can be used independently of, or in conjunction with, the raise/lower function of the RUSSELL Elevating Platform.
The RUSSELL Elevating Platforms are sturdy, with profile-following, floor extension on the Mill edge of the RUSSELL Elevating Platform providing for safe work operation at all points along the curvature of the Mill.
The THUNDERBOLT S3 Power Pack with its visual control and diagnostics panel, provides the power for the RUSSELL Elevating Platform and on board equipment.
THUNDERBOLT Recoilless Hammer Jibs are mounted on the RUSSELL Elevating Platforms, freeing up space around the Mill and providing a safe and clear plant floor.
RUSSELL Elevating Platforms are powered by the THUNDERBOLT S3 Power Pack, and are also fitted with an on-board swing arm Jib with a spring balance for pneumatic tools, eliminating the need for Monorails around the Mill. Hydraulic and pneumatic outlets with common attachments are accessible on board the RUSSELL Elevating Platforms, offering additional redundancy in the case of hose or lead failure.
