Retsch Jaw Crushers are used for the rapid, powerful crushing and pre-crushing of mediumhard, 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.

Applications & Details Jaw crushers are always at the very front of the sample preparation chain, pre-crushing all hard and brittle materials. They 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 8 different sizes: BB 50, BB 100, BB 200, BB 300 and the bigger models BB 250, BB 400, BB 500 and BB 600. Throughput and final fineness depend on the crusher type, selected gap width and breaking properties of the sample material. Feed sizes range from 40 mm to 350 mm, depending on the model. The main fields of application of jaw crushers are construction materials, mineralogy and metallurgy, ceramics and glass, materials research and environmental analysis. RETSCH Jaw Crushers are characterized by many unique details allowing for convenient and safe sample processing. Benefits at a glance (depending on model) High throughput, high degree of size reduction High final fineness (down to d90 <0.5 mm) Zero point adjustment for wear compensation Breaking jaws made of different materials No-rebound feed hopper Easy-to-clean crushing chamber Belleville spring washer provides overload protection Jaw Crusher technology RETSCH Jaw Crushers are robust and powerful forced-feed crushers. The feed material passes through the no-rebound hopper and enters the crushing chamber. Size reduction takes place in the wedgeshaped area between the fixed crushing arm and one moved by an eccentric drive shaft. The elliptical motion crushes the sample which then falls under gravity. As soon as the sample is smaller than the discharge gap width, it falls into a removable collector. The continuous gap width setting with scale resp. digital display ensure optimal size reduction in accordance with the set gap width value. Integral Belleville spring washer packages and a thermal overload protection switch protect the jaw crushers against overloading.

Size reduction takes place in the wedge shaped area between the fixed crushing arm and one moved by an eccentric drive shaft. The elliptical motion crushes the sample which is moved towards the crushing gap under gravity. As soon as the sample is smaller than the discharge gap width, it falls into a removable collector within the jaw crusher. The continuous gap width setting with scale ensures optimum size reduction in accordance with the set gap width.
