The BB 50 is the smallest model of the RETSCH jaw crusher series and has been specially designed for sample preparation in the laboratory. The compact machine fits on any laboratory bench and offers safe and convenient handling. The RETSCH jaw crusher series is available in 8 different sizes. Throughput and final fineness depend on the crusher type, selected gap width and breaking properties of the sample material. Robust design, simple handling and cleaning are the features of the RETSCH jaw crusher models. Small amounts of sample are processed batchwise; for larger amounts the crushers can be operated continuously. Powerful & Compact High crushing efficiency, feed sizes up to 40 mm can be crushed to 0.5 mm Removable jaw for easy cleaning Adjustable speed allows adaptation to sample characteristics Wear compensation with zero-point adjustment Convenient operating keypad with digital display Memory for gap width setting Superiority in detail The BB 50 is designed for efficient and convenient size reduction. The variable speed can be set between 550 and 950 min-1 to adapt the crushing process to sample requirements. The possibility to reverse the rotating direction is helpful if too much sample material has been fed to the crusher causing it to block. The simple push of a button restarts the process. Due to permanently lubricated bearings and its solid design, the BB 50 jaw crusher is virtually maintenance-free. Zero Point Adjustment An advantage of the jaw crusher BB 50 is the so-called zero point adjustment. Sooner or later, the breaking jaws will show signs of wear which will affect the reproducibility of the size reduction process.
