Sandvik Rock Processing has signed an agreement for 5 Hydrocone H8800 cone crushers with El Teniente in Chile, which is part of the Codelco Group and one of the world's largest underground copper mines. In 1998 El Teniente installed its first Hydrocone crushers. The company has during the years expanded its use of Hydrocone crushers and with this addition of another 5 crushers El Teniente will in total have 13 units running. The crushing method in the mine will completely be based on the Hydrocone technology, which includes secondary and tertiary applications as well as pebble circuits for the SAG mills.
