Operating principle of a jaw crusher

Jaw crushers are the ideal choice for fast primary crushing of hard, medium-hard and brittle materials. The material to be crushed is fed through a hopper into a shaft formed by two crushing jaws. One crushing jaw is fixed, the other is driven by an eccentric shaft and thus moves towards the fixed crushing jaw at regular intervals. The material is crushed by this elliptical movement between the two jaws. If it is finer than the set minimum distance, it falls through between the two jaws and can be collected in a container.

Jaw crushers in the laboratory Applications

Jaw crushers are used in a wide range of industries. They can be used in the mining industry for crushing rock, but also in the construction industry for pre-crushing aggregates. In addition to industrial use, jaw crushers can also be found in laboratories and in pilot plant facilities. Jaw crushers in the laboratory, for example, can be used in a more robust environment to prepare coarse materials for further production steps. Another possible application is the quality control of raw materials. The materials to be crushed range from ...

  • Building materials,
  • minerals,
  • metals,
  • ceramics and

to medical materials such as bones. In addition, these all-rounders provide valuable services in material development or environmental analysis, for example for primary crushing of soil and rock samples.

Selecting a jaw crusher for the laboratory - what are the criteria?

Due to the wide range of applications, laboratory jaw crushers come in different sizes. There are variants as stand-alone crushers or as table-top crushers. In addition to this distinction, the crushers can be used as batch gates or integrated directly into production processes as online gates.

Material type

Depending on the hardness of the substances to be cr ushed, a different type of material is suitable for the crushing jaws. Possible materials are, for example, stainless steel, manganese steel, zirconium dioxide or also tungsten carbide, which is characterised by a particularly high hardness. With some tools, special heavy metal-free crushing jaws can also be selected for relevant applications. The materials to be processed range from hard ceramics to brittle bones.

Final fineness

Another distinguishing feature is the final fineness to be achieved. For this purpose, the gap width between the crushing jaws can be specifically adjusted. Furthermore, a distinction can be made as to whether the gap width can be adjusted steplessly or at predefined intervals.

Max. Feed size

The size of the material to be crushed also has a major influence on the selection of the appropriate crop. In most cases, floor-mounted grinders are suitable for larger grain sizes, typically materials up to 15 cm in diameter can be used as feed material. Table tools are the specialists for finer material, where the starting grain sizes are usually in the range of a few centimetres.
