Jaw Crusher BB 250
Retsch | Sample Preparation - Inorganic
The Jaw Crusher BB 250is used for the rapid, effective crushing and pre-crushing of medium-hard, hard, brittle and tough materials.
For small amounts of sample the BB 250 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.
Application Examples
alloys, basalt, cement clinker, ceramics, chamotte, coal, coke, construction materials, feldspar, glass, granite, minerals, ores, oxide ceramics, quartz, rocks, silicon, slag, ...
