Electronic blast initiation system
Dyno Nobel says its new DigiShot electronic initiation system provides more vibration control, increased crusher throughput, greater highwall stability, and improved operational efficiencies. The system requires minimal end-user training time with its easy-to-use, menu-driven software. Blast patterns and timing can be programmed either directly into the DigiShot or downloaded from a PC-based design program in advance of or on the day of the shot. Easy auto-programming saves time and reduces errors; the manual programmable mode accommodates virtually any delay scheme.
Skirting extends wear life of belts
Martin Engineering says its improved Apron Seal skirtboard sealing system provides double the wear life for conveyor belts. The skirting provides two wear surfaces on a single elastomer sealing strip installed along the bottom of the skirtboard in a belt conveyor loading zone. When the bottom side of the strip against the belt is worn, the sealing strip is inverted, providing a second service life. Skirtboard sealing systems are installed on the sides of belt conveyor loading zones to contain material, eliminate spillage, and reduce cleanup expenses. The skirting is available in lengths up to 300 feet.
Silent pump with autostart
Gorman-Rupp Co.’s priming assisted silent pump offers pumping capacities to 920 gallons per minute and heads to 134 feet, and handles 3-inch-diameter spherical solids. The company says its patented priming system uses a venture and compressor, eliminating the leaks associated with traditional vacuum-assisted pumps. An oversized, oil-lubricated mechanical seal allows the pump to run dry continuously without damage.
Large, weather-proof storage
TekSupply says its ClearSpan Hercules truss arch buildings are now available up to 250-feet wide and can be built to any length, making them ideal for storing equipment and supplies in aggregates plants. The frames are Allied Gatorshield structural steel frames; the covers are made from high-quality rip-stop polyethylene. The polyethylene covers let the sunlight through, eliminating the need for daytime artificial lighting. The structures provide height and clearance, making it easy to maneuver equipment, and the lack of interior support columns allows more usable storage space.
