Laboratory jaw crusher for sample preparation
Achieve precise size reduction and sample preparation with this compact jaw crusher, designed to handle diverse materials from ceramics to cement clinker, ensuring consistency and reliability in your lab processes.
Crushes and Reduces Samples Efficiently
The Jaw Crusher BB 50 from Retsch is a compact, benchtop solution designed for reliable sample preparation in laboratory environments. This robust jaw crusher is engineered to process medium-hard, hard, brittle, and tough materials, reducing them down to fine powders with ease. Notably efficient for producing mineral samples, ceramic powders, and pharmaceutical powders, its forced-feed crushing principle ensures consistent results. With adjustable speed settings between 550 and 950 min-1 and a reverse rotating direction feature, the BB 50 accommodates various sample characteristics and prevents blockages. Operable in both batch and continuous modes, it integrates seamlessly into laboratory workflows. The device is made from durable materials like manganese steel, stainless steel, and tungsten carbide, ensuring wear resistance and longevity. The BB 50 is virtually maintenance-free thanks to its wear compensation with zero-point adjustment and permanently lubricated bearings. Users benefit from a digital display for gap width settings and the option of a dust-tight, large collection receptacle, enhancing cleanliness and sample integrity.
