Laboratory jaw crusher for sample preparation
In laboratory environments, preparing samples for analysis often requires reducing the size of medium-hard, brittle, or tough materials. Achieving precise, reproducible particle sizes efficiently can be challenging, particularly when processing small quantities intermittently.
Ensures precise size reduction for lab samples
The Retsch Jaw Crusher BB 50 is a compact benchtop unit designed specifically for grinding and size reduction of laboratory samples. The device handles material feed sizes up to 40 mm and crushes them down to less than 0.5 mm. The adjustable speed range from 550 to 950 min^-1, as well as the zero-point adjustment feature, allows fine-tuning of the crushing process to suit the sample’s characteristics. Designed for efficiency, the BB 50 has a no-rebound hopper and an eccentric drive for optimal size reduction within a space-saving design. Its maintenance-free operation is ensured by permanently lubricated bearings. The crusher is virtually maintenance-free and facilitates easy cleaning with removable components. Key industries benefiting from this technology include construction materials, metallurgy, geology, and pharmaceuticals. Supplied by Retsch GmbH, the unit also includes a digital display for gap width, and compatibility with various jaw materials such as manganese steel and tungsten carbide.
