Big Wheels Keep on Turning
With diesel fuel prices skyrocketing, producers are taking a close look at this alternative to conventional haulage and crushing—and following up with purchase orders
By Kyran Casteel, E&MJ European Editor
Large, semi-mobile crushing plants have been an option for open-cut limestone, coal and metal operations for a long time now, since 1956 at least. The advantages of inpit crushing/conveying systems have been well-established since then but in the 1990s the availability of increasingly large haul trucks limited their appeal to some extent. More recently, though, mine developers taking advantage of increasing demand for coal and mineral commodities have paid more attention to the in-pit crushing and conveying (IPCC) option. Leading suppliers MMD Sizers, Sandvik, TenovaTAKRAF and ThyssenKrupp Fördertechnik……. read

Gearless Mill Drive Sales Rev Up to Meet Demand
By Russell A. Carter, Managing Editor
There are few phases of mining and processing that don’t require the assistance of electric motors. From electric wheel drive haul trucks to battery-powered LHDs, a significant portion of the industry’s mobile equipment is propelled by large electric motors that require precise, reliable starting, stopping and speed control, generally under harsh conditions. In the plant, grinding mills are spun at vertigo-inducing production speeds by electric motors that also can inch and creep 40-ft-diameter...... read

 Mozambique Becomes a Major Coking Coal Exporter?
In addition to its potential role as a major international supplier of coking coal, Mozambique will also become a major source of power generation for southern Africa
By Antonio Ruffini, E&MJ South African Editor
Projects under way and planned in Mozambique’s Zambezi Valley coal basin will turn that country into one of the world’s major suppliers of seaborne coking coal. Located in the country’s northeastern province of Tete, what is one of the world’s largest undeveloped coking coal regions will also become a significant source of electricity generation for southern Africa.
The best known of the companies active in the Zambezi coal basin is Vale with its Moatize project, but there are others, such as Camec, Coal India Ltd…...

 Body of Work
Selection of the right dump body for the job requires careful thinking, both inside and outside the box
By Russell A. Carter, Managing Editor
The recent introduction of Komatsu’s largest haul truck, the 360-ton-capacity 960E-1 (see sidebar, p. 74), serves as a king-sized reminder of the vast amount of technology contained in almost any type of modern mine production equipment. From tires to transistors, today’s haulers feature components that are often much stronger, larger, smaller, or smarter than those of a decade ago, and the trucks themselves offer levels of reliability, performance, control, vehicle health monitoring and diagnostic capabilities that were for many years just designers’ daydreams.....

Mill Trunnion Magnet System Protects Plant Equipment
- The practice of using magnets to collect ferrous metal from process streams has had a long history in the mining industry. The first application, and the most prevalent application today, is the removal of ferrous tramp metal from conveyor belts. This is a straightforward application that involves suspending an electromagnet over the conveyor belt. Recently, magnetic separation techniques have been developed to effectively collect tramp metal, such as grinding ball fragments, from mill process streams .……
