Cone crusher basics in 4 minutes — SRP

The basic principle is straightforward: the material to be crushed (the feed), drops into the crushing chamber. The mantle is a moving part that gyrates in an eccentric motion. That is, it doesn''t remain completely centred – it swings slightly as it rotates, continually altering the gap between the mantle and the concave (the ring outside ...
