Jaw crusher for medium-hard to hard materials
Optimize your material processing with a powerful solution for efficiently reducing large feed sizes into precise, uniform particles, enhancing your production’s capacity and throughput.
Crushes and Reduces Industrial Materials
The Jaw Crusher BB 250 from RETSCH is engineered for the challenging demands of industrial crushing applications. Designed to handle a variety of tough materials like ores, ceramics, and slag, it operates through a robust forced-feed principle, ensuring efficient size reduction. The wedge-shaped crushing chamber, with its adjustable gap width, accommodates feed sizes up to 120 x 90 mm, achieving final fineness down to 2 mm and a throughput of up to 300 kg/h. Ideal for construction, mining, and geology sectors, the BB 250 is versatile for both batch and continuous processes, integrating seamlessly with existing production lines. It boasts easy-cleaning features with a front door access to the crushing chamber and optional dust extraction for maintaining operational cleanliness. Available in multiple material options, including manganese and stainless steel, it offers contamination-free grinding for precise analytical results. Perfectly suited for pre-crushing in R&D labs and small-scale production, this jaw crusher supports your need for innovation and efficiency.
