Jaw Crusher BB 400

Retsch | Sample Preparation - Inorganic

The Jaw Crusher BB 400 XL is used for rapid, effective crushing and pre-crushing of medium-hard, hard, brittle and tough materials.It is available in a wide range of materials of construction including heavy-metal free steel and offers excellent efficiency and unrivaled safety making this jaw crusher ideal for sample preparation in laboratories and industrial plants. For small amounts of sample the BB 400 XL is usedbatch-wise; for larger amounts it can be operatedcontinuously. Control of the gap width and zero point adjustment allow for reproducible results.

Thanks to the modular construction of housing and frame this jaw crusher is suitable for a wide range of applications.
