Shot Rock It is formed by drilling and blasting the basalt deposit and is usually supplied from the freshest and bluest rock unless otherwise specified. It typically ranges in size from 700mm down to fines though due to the nature of its production can range upwards depending on the blasting parameters used on each specific shot.Read More
Approximately 40,000 tonnes of rock are loosened with each blast. Free stone is then transported via 70-tonne haul trucks to the 137cm gyratory crusher which crushes the stone at a crushing rate of 1,500 tonnes per hour. Large pieces of limestone are crushed to approximately 15-20cm in diameter.Read More
