Steel-Cord Conveyor Belt Splices—More than Tough Enough

Steel-Cord Conveyor Belt Splices—More than Tough Enough

By Bernd Küsel

The introduction of steel cord conveyor belts more than 50 years ago revolutionized conveyor technology. Since then, increasingly longer conveyors, higher loads and more complex routing have become possible, with no end to these advances in sight. Because every conveyor has one or more individual belt sections that must be spliced to make an endless conveyor belt, this record of success has relied heavily on splicing technology. This article describes experience that has been gathered with steel cord conveyor belt spices in various application fields in opencast and underground mining.

Getting the Facts Right for Idler Rightsizing

Getting the Facts Right for Idler Rightsizing

Mining operation finds upsizing to CEMA E idlers worth its weight in gold.

Barrick Gold Corp. maintains 27 operating mines and boasts the largest gold and copper reserves in the industry. Barrick is targeting its 2009 gold production at approximately 7.6 million oz and copper production at 400 million lb. Its Goldstrike property, located near Elko, Nevada, USA is the company’s largest gold producing operation with output exceeding 1.65 million oz annually and an employee roster topping 1,300 workers. Treating ore from one open pit and two underground operations, the Goldstrike mine combines two processing facilities—an autoclave circuit, which treats non-carbonaceous sulphide (refractory) ore; and the roaster, which treats carbonaceous ore.

Marland Clutch Backstops Guard Boddington Conveyors

Conveyor systems are increasingly being designed to operate on steeper grades, at faster transfer rates, and with higher drive-power levels to satisfy rising mine and plant production targets. With ore being transported up inclines that can easily span eight stories in some plant installations, a reliable belt backstopping system is crucial to prevent a loaded belt from racing backwards out of control in the event of an unplanned power outage or mechanical failure in the drive.

Diamond Mine’s Equipment Availability Shines with Computer-Assisted Management

Located in South Africa’s Limpopo Province not far from the Botswana and Zimbabwe borders, De Beers’ Venetia open-pit diamond mine spans 3 km across and is more than 400 m deep. It is one of the biggest and most productive diamond mines in the world, currently mining about 60 million mt/y of rock to yield 8.2 million carats of diamonds. It also achieves extremely high equipment availabilities.
