Improved blasting system Dyno Nobel and its joint venture partner, DetNet, offer the new DigiShot 300 RF system, which is designed to improve safety of blasting operations. The system is designed for single-box firing with the capability of firing up to 450 detonators at a distance of 3,281 feet. It will also support box synchronization of two boxes when firing in hardwire mode. The software allows the machines to be configured as either a bench box or base station, while smart key technology improves safety and security. Dyno Nobel | www.dynonobel.com Versatile screen plant Terex Minerals Processing Systems expands its CR Series portable plant line with the Terex Cedarapids CRS620S screen plant, which features the patent-pending LJ-TSV screen. The screen is said to increase production and application opportunities through the combination of the El-Jay high G-force oval stroke motion and adjustable slope operation. Hydraulics can change the screen slope in 2.5-degree increments up to 7.5 degrees, as fits the application. Screen openings are available up to 6 inches. A patent-pending "slant spring" screen suspension provides stability at all slopes. A 48-inch-wide fines conveyor with elevated discharge and two 30-inch-wide reversible cross conveyors extend up to 42 inches beyond the main frame to feed off-plant conveyors. Roll-away blending chutes and extended walkways allow easy access to screen cloth.
