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 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 40 mm to 130 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

  • 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.
