Sandvik DD322i is a versatile drill that can be utilized in mining or tunnelling applications, and provides a high level of performance, accuracy and reliability. Sandvik DD322i has a new carrier and design, and can tram in small headings, tight corners and intersections thanks to its compact size, low profile cabin and “Boom Control While Tramming” option.
“Sandvik DD322i was well-received by our customer during the field testing in Finland,” said Jari Talasniemi, product manager for development drills, about customer evaluations made in 2022. “The site reported that almost 60 percent of their development drilling during the trial period was completed using Sandvik DD322i. It performed extremely well from day one and the “Boom Control While Tramming” feature was useful for their operation.”
Improved Control While Moving the Drill
The “Boom Control While Tramming” option allows the operator to simultaneously control the two booms while moving the drill. This ensures improved control during tramming and reduces potential risk of boom damage. The new SB55i booms with two rollovers improve drilling performance and accuracy. They also ensure a high flexibility to drill cross passages and bolt holes. Sandvik DD322i can be equipped with features such as semi automatic drill bit changer and tele-remote drilling.
Extended Lateral Range
Sandvik DD322i provides flexibility for operations, starting from small size drifts up to 58 m2 coverage area, reaching up to 6.8 m high and 9.5 m wide. The new SB55i booms provide 19.3 m2 side coverage, which is over 48% more than its predecessor DD321.
The low profile cabin has been redesigned and the new larger glass doors offer 55% more visibility, maximizing safety and improving operator comfort while creating a modern, spacious and ergonomic working environment. Larger displays provide an improved user interface and Sandvik DD322i is compatible with Sandvik’s digital offering, including Sandvik DrillConnect, iSURE, AutoMine, OptiMine and My Sandvik.
Scalable automation packages and tele-remote drilling are available as options for Sandvik DD322i, enabling better drill utilization and continuous working hours over shift changes and during blasting and ventilation hours.
