Jaw Crusher BB 200

The RETSCH BB 200 is a robust jaw crusher for coarse and preliminary size reduction of hard, brittle and tough materials. With adjustable crushing gaps and throughput up to 300 kg/h, it prepares samples for further processing and laboratory analysis.

Applications

The BB 200 uses pressure crushing to reduce medium-hard, hard, brittle and tough materials. It supports batch processing of small sample quantities and continuous crushing for larger workloads.

• Construction materials: Crush concrete, cement clinker and other construction materials for material testing and quality control.
• Geology and metallurgy: Reduce ores, granite, quartz, slag and tungsten alloys before further grinding and analysis.
• Environmental and recycling: Prepare glass, coal and other suitable waste or recycled materials for subsequent testing and processing.
• Chemistry and ceramics: Crush oxide ceramics and other suitable materials for laboratory analysis and material characterization.
• Engineering and electronics: Prepare suitable engineering materials and electronic-related samples for further examination.
• Semiconductor materials: An optional special configuration supports heavy-metal-free crushing, helping prevent metallic contamination during sample preparation.
