Thor Global has delivered a ThorLoPro low profile portable radial telescopic conveyor to a gold heap leaching application in Mexico. At this location, gold ore is crushed and conveyed from two separate crushing plants into a surge pile that feeds multiple transfer conveyors, a bridge conveyor and finally the LPT140x42-1200, 140ft (42.7m) by 42in (1050mm) low profile telescopic stacker.
The LPT140 fits perfectly into the site’s existing low profile bridge or indexing conveyor via a rotating pivot pin system. Thor Global designed a custom removable 5th wheel pin to accommodate this unique operations mode anchoring system.
The patented low profile design has the added benefit of preventing spillage due to the fact that the feed point height remains constant while the conveyor is being raised and lowered. Dual radial wheel drives was an essential optional feature for this application in order to overcome the inherent difficulties of operating over several layers of previously stockpiled material.
Thor Global’s patented push down axles are instrumental in providing a seamless LIVE operation for this heap leaching application.
This optional feature allows the operator to move the telescopic conveyor multiple times without shutting down any belts in the conveying sequence. As the push down axles are engaged the radial arms rise off the ground, while remaining in their fully extended radial mode. The bridge conveyor then pulls the telescopic back into its next position. During this entire transition, material continues running off the belts NONSTOP!
