including touch screens.
Sandvik Mining and Rock Technology has delivered and commissioned the
first DR461i (now identified as the DR412i) rotary blasthole drill to the
African continent. According to the company, this next generation blasthole
drill drastically improves productivity, while returning better-than-ever fuel
efficiency and vastly improved availability compared with its predecessors.
The Sandvik DR412i is focused on the changing requirements of surface
miners and is designed to improve conservation and deliver dependable
penetration in the world’s harshest mining conditions. Constructed for rotary or
down-the-hole drilling, the DR412i is automation-ready and built to guarantee
reliability while bringing a new level of safety and productivity to any operation.
The DR412i is designed for a hole range of 216–311mm (8½–121/4ʺ) with
high- and low-pressure versions available and with a multi-pass maximum hole
depth of 75m (246ʺ).
The DR412i cab has increased space and visibility.
