This jaw crusher is designed to process even difficult-to-grind samples safely and reproducibly to a final fineness of between 1 and 15 mm. With a maximum continuous throughput of 200 kg/h, the device is ideal for routine use and larger quantities of material in industrial or scientific operations. Technical features at a glance

• Connection values: 400 V/3~, 50-60 Hz, 2780 W
• Maximum feed size: 95 mm
• Grinding tools: Fixed & movable crushing plates, materials selectable (hardened steel, stainless steel, chrome-free steel, manganese steel, tungsten carbide, zirconium oxide, aluminium)
• Final fineness depending on setting: 1 - 15 mm
• Maximum continuous throughput: 200 kg/h
• Eccentric movements: 308 movements/min
• Dimensions: 40 x 80 x 80 cm, weight: 205 kg

The special combination of fixed and counter jaws enables very uniform, gentle and efficient grinding. Operation can be either batch or continuous inline. Particularly noteworthy is the optimal adjustability of the crushing gap for different sample types, which guarantees high reproducibility and precision.

The large selection of grinding tools made of different materials protects against cross-contamination and makes the jaw crusher suitable for sensitive analyses as well.

Compliance with relevant safety and quality standards

This jaw crusher complies with the applicable European Machinery Directives and bears the CE mark. This guarantees compliance with important standards and regulations in laboratory operation, particularly with regard to user protection, electrical safety and hygiene regulations. Optionally available access safeguards and a well-designed emergency stop concept ensure additional occupational safety.

Focus on practical applications

In harsh real-world use, the device is particularly impressive in the following areas of application:

• Building material analysis: Different building materials such as concrete, sand-lime brick or brick can be easily ground for subsequent examination. Ideal for sample preparation in building material laboratories or on-site quality control. Mineralogical and geoscientific investigations: Perfect for grinding ore, quartz or rock samples that are to be chemically analysed.
• Metallurgy: Samples of iron, steel or non-ferrous metals are prepared for metallographic examination or non-destructive material analysis.
• Ceramics and glass industry: Fragments of various ceramics or glasses can be optimally prepared for granulometric evaluation.

Typical substances that are crushed include silicates, various minerals, precious and industrial metals, technical concrete, bauxite, quartz, fine ceramics and special glasses. The jaw crusher is also highly relevant for the analysis of recycled materials in the building materials cycle or for the quality assessment of raw materials in the manufacturing industry.

FAQs

How does crushing work in a jaw crusher?

• The sample material is fed between two crushing jaws via a feed hopper. While one jaw is fixed in place, the other moves by means of an eccentric shaft and mechanically presses the material until the desired fineness is achieved.

For which materials are the grinding tools particularly suitable?

• Depending on the selected material of the crushing plates, the system is universal: carbide for abrasive samples, stainless or chrome-free steel for pure samples, manganese steel for tough materials, zirconium oxide or aluminium for special requirements in terms of contamination-free processing.

How is overfilling of the device prevented?

• The maximum feed size of 95 mm and safety features ensure that overfilling is practically impossible.

Is it easy to clean between sample changes?

• Yes, the special design and accessible grinding system allow for quick and easy cleaning to prevent cross-contamination.

Conclusion

The device combines precise grinding with maximum sample diversity, coordinated safety systems and easy handling. Laboratories and industrial companies that value repeatable and standard-compliant sample preparation will find this jaw crusher to be a future-proof solution for a wide variety of materials and applications.
