Metso has introduced the world´s largest cone crusher, MP2500, to respond to the mining industry´s efficiency challenge. The first MP2500 cone crusher will be operational at First Quantum Minerals Ltd Sentinel mine in Zambia by early 2015.
The MP2500 was selected for Sentinel because it can process large volumes of rock as single machine. It saves costs as fewer crushers, related infrastructure and maintenance are needed for achieving the same or increased amount of production. Because the MP2500 crusher has the largest feed opening ever made, it can crush bigger chunks of rock. Its ability to crush rock further than the traditional crushers decreases energy consumption in the later parts of the process.
The MP2500 cone crusher is designed for use in secondary and tertiary crushing. It links easily with other Metso products to create a simplified, cost-effective process flow for high production sites. Larger equipment reduces the number of crushers to install since there is more throughput from each crusher. To duplicate the performance of two MP2500s would require four smaller MP1250s and all associated infrastructure. Serviceability and ease of maintenance was also a focus during the design. Since the part was so large, Metso developed a new method to remove the socket which eliminates heating of the part in a difficult working space. This method also eliminates process variables associated with socket removal and reduces the overall stress on both the socket and main shaft. Metso has a patent pending for this new concept.
