Retsch® BB 50 Jaw Crusher, Compact Benchtop Model | 200–240 V, 50/60 Hz

The RETSCH BB 50 Jaw Crusher is a space-saving, benchtop instrument designed for the rapid and gentle crushing of medium-hard, hard, brittle, and tough materials. Tailored specifically for laboratory environments, it delivers reliable performance for small-volume sample preparation across various industries including mining, materials science, pharmaceuticals, and environmental testing.

This compact jaw crusher features a digital display for precise gap width adjustment and a variable speed range of 550 to 950 rpm. The adjustable gap width (0–11 mm) allows for reproducible results, while the zero-point adjustment function compensates for jaw wear to ensure long-term consistency. Designed for ease of use, the BB 50 includes a fold-back hopper and removable crusher arm, allowing tool-free access to the grinding chamber for fast cleaning and jaw exchange.

The unit processes feed materials up to 40 mm and reduces them to final finenesses down to approximately 0.5 mm, depending on the material. The 3-liter collector accommodates small batch sizes, making the BB 50 ideal for routine lab use or specialized testing protocols. Multiple jaw materials are available—including manganese steel, stainless steel, tungsten carbide, and zirconium oxide—to prevent contamination and meet specific analytical needs.
