Design of a crushing system that improves the crushing efficiency of
2.5.1: Gyratory Crusher 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

Underground Crusher Selection and Design
If the capacity you require falls within the capabilities of a jaw crusher then go for that option. Gyratory crushers come into their own when the feed size is largely uncontrolled and when direct tipping at high capacity is required. Typically in underground operations the crusher feed is not coarse and lumpy as in an open pit and is usually

Other processes, however, include pick breakers, jaw crushers, gyratory crushers, and roll crushers or a process involving some combination of these techniques. It is usually desirable to minimize the amount of fines (particles finer than ∼0.5 mm) produced in size reduction, since these are very difficult to handle in the subsequent cleaning and dewatering operations.

Primary crushers are designed so that the maximum size that can be presented to the crusher is approximately 80% of the gape. Jaw crushers are operated to produce a size reduction ratio between 4 :1 and 9 : 1. Gyratory crushers can produce size reduction ratios over a somewhat larger range of 3 :1 to 10 :1.
