  • Design of a crushing system that improves the crushing

    Gyratory crushers are the most efficient primary crushers for dealing with blasted hard rock in ore and natural stone mining. Due to different crushing chamber designs these machines can either prepare materials for downstream processing with a high crushing ratio, or reduce overburden to a size suitable for belt conveying with a low crushingHandbook of Crushing,crusher. Primary Crusher — The first crusher in a crushing system into which material is fed. Succeeding crushers in the system are referred to as secondary or tertiary crushers. Product — Output from the crusher. Reduction Ratio — The ratio of the top size of input material to the top size of crusher
