Applications BB 50 | BB 100 | BB 200 | BB 300 The main areas of application for jaw crushers are: RETSCH jaw crushers are used for the rapid, gentle crushing and pre-crushing of medium-hard, hard, brittle and tough materials. The variety of materials offered, their efficiency and safety make them ideal for sample preparation in laboratories and industrial plants. Typical sample materials include rocks, minerals, ores, glass, ceramics, construction materials, brittle metal alloys, slag, resins and many other hard and brittle substances. Ceramics and glass glass, oxide ceramics Construction...

Powerful crushing and pre-crushing her A suitable jaw crus for any application Jaw crushers are always at the very front of the sample preparation chain, precrushing all hard and brittle materials. RETSCH jaw crushers are primarily used in laboratories and pilot plants under rough conditions but are also suitable for on-line quality control of raw materials. The jaw crushers are available in 4 different sizes: BB 50, BB 100, BB 200 and BB 300. Throughput and final fineness depend on the crusher type, selected gap width and breaking properties of the sample material. Feed sizes range from...

BB 50 – Powerful and compact benchtop model Laboratory scale pre-crushing 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 space-saving instrument fits on any laboratory bench. Small amounts of sample with large feed sizes are crushed gently and without loss. The jaw crusher BB 50 possesses a robust metal housing which cannot be accessed by hand. Reproducible results are ensured by the zero-point adjustment of the gap width. This means that any breaking jaw wear can be compensated by simply...

Jaw crusher BB 50 Superiority in detail Fold-back hopper can be removed for easy access Setting the gap width to determine the final fineness The BB 50 is designed for a very efficient and convenient size reduction process. 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. There is no need to empty the crushing chamber manually. Another advantage...

BB 100, BB 200, BB 300 – Robust and versatile floor models Benefits at a glance n High throughput, high degree of size reduction n High final fineness (down to d90 <2 mm) n Continuous gap width setting n Scale for gap width display n Zero point adjustment for wear compensation n Central lubrication (BB 200, BB 300) n Breaking jaws made of 4 different materials n No-rebound feed hopper with quick-release clamp n Brake motor with safety switch n Easy-to-clean crushing chamber n Process line versions of BB 200 and BB 300 available Convenient and safe power packages Robust design, simple hand­...

Jaw crushers for special requirements BB 200 No-rebound fold-back hopper Bolt for easy removal of crushing arm Apart from the four standard models, RETSCH jaw crushers are also available as special versions adapted to particular application requirements. Continuous pre- and fine grinding 90 mm Scale for gap width display and zero point adjustment For the rapid, continuous grinding of large quantities of coarse material to analytical fineness, the combination of the RETSCH jaw crusher BB 200 and the RETSCH Disc Mill DM 200 is the perfect solution. The crusher is mounted above the disc mill...

Selection guide for jaw crushers The choice of jaw crusher depends primarily on the feed material size and the amount to be crushed. With its compact space-saving design, model BB 50 is often used in laboratories for pre-crushing small amounts of sample. Performance Data Series BB 100, BB 200 and BB 300 jaw crushers are mainly used for pre-crushing hard, brittle products with a degree of hardness >3 on the Mohs' scale. Models BB 200 and BB 300 are also suitable for size reduction in process plants, e.g. when included in a sam­ ling station. p Feed material medium-hard, hard, brittle, tough...

Jaw crushers BB 50 | BB 100 | BB 200 | BB 300 ls 5 different materia available The suitable material for your requirements Selecting the breaking jaw material Breaking jaws made from different materials are available for different applications: n Manganese steel is a material whose structure becomes compressed under pressure and becomes harder with time (cold hardening). n Stainless steel is recommended if the expected feed material is not too hard and could cause corrosion. n Tungsten carbide is the most abrasion-resistant and pure material. It provides an in­ reased working life c even...
