Types of Crushers Explained: Everything You Need to Know

Impact crushers are the secondary crushers or the tertiary crushers that use high speed impact forces to break the materials. They are a set of rotors with hammers or blow bars mounted on them that crush the material as it enters the crushing chamber. This phenomenon results in the material to be cracked and fragmented into smaller pieces.

Effect of Feed Rock Size Distribution on Crusher Performance

More often than not the discharge setting, even in primary crushers, is such that the crushed material in the lower part of the crushing chamber effectually throttles the flow of fine material to the pace of the larger pieces; hence, any increase in capacity would be due entirely to whatever increase in density of the body of material might ...

Crushing it

The primary crushing stage generally breaks down the material into pieces of max 200 – 300 mm. The aim is to achieve the right balance between feed size (capacity) and throughput (speed). Reaching this balance is important, as focusing on one aspect, while neglecting the other, could lead to an unsuitable choice of equipment.

Cone crusher basics in 4 minutes

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 ...
