Types of Crushers: What You Need to Know

A roller crusher reduces material by compressing it between two turning cylinders, parallel to each other. The cylinders are mounted horizontally with one resting on strong springs and the other framed permanently. Material is then fed between the two. Changing the distance between the rollers allows you to control the desired material output size.

Optimal feed arrangement

A pre-crusher surge bin with a low-level monitor connected to the control system can also ensure proper feeding. Spider-arm placement Segregated feed – when coarse and fine particles enter different parts of the crushing chamber – is a major cause of premature liner wear and sub-optimal performance.
