Standard: ASTM C289
Laboratory Jaw Crusher
The Laboratory Jaw Crusher is a small-scale machine designed to facilitate material size reduction of aggregates and common minerals such as rocks and ores with medium hardness through precise mechanical force. It features adjustable jaw opening and output size settings, and high operating rpm with lower dust generation. These attributes empower researchers to tailor the crushing process for sample preparation with specific testing requirements in metallurgy, geology, building material, and chemical industries for experiment and laboratory use. They are often employed to crush rocks, minerals, ores, and other solid materials to a size suitable for further analysis or experimentation and to obtain crucial data for their research endeavors.
Features of Laboratory Jaw Crushers
1. Adjustable Jaw Opening - This feature allows researchers to control the size of the material being crushed, enabling customization for different testing requirements and sample types.
2. Output Size Settings - Jaw crushers typically offer options for adjusting the output size of crushed material, providing flexibility in obtaining the desired particle size for further analysis or experimentation.
3. High Operating RPM - Jaw crushers often operate at high rotational speeds, enabling efficient crushing of materials and maximizing throughput.
4. Lower Dust Generation - Advanced designs and technologies in jaw crushers help reduce dust generation during the crushing process, creating a cleaner working environment and minimizing contamination of samples.
5. Precise Mechanical Force - Jaw crushers exert precise mechanical force to crush materials effectively, ensuring consistent and reliable results in sample preparation.
6. Versatile Application - Jaw crushers are versatile machines suitable for crushing a wide range of materials, including aggregates, rocks, minerals, and ores with medium hardness, making them valuable tools in various industries such as metallurgy, geology, building materials, and chemistry.

Standard
ASTM C289 - A standard test method established by the American Society for Testing and Materials (ASTM) that defines the procedure for determining the potential alkali-silica reactivity of aggregates through a chemical method known as the "Chemical Method for Potential Reactivity of Aggregates (pH Test).
Test Procedure of Laboratory Jaw Crusher
1. Preparation of Sample - Start by preparing the sample material to be crushed. This may involve reducing large chunks of material into smaller pieces using appropriate tools such as a hammer or a mortar and pestle.
2. Adjustment of Jaw Opening - Set the desired jaw opening size on the laboratory jaw crusher according to the requirements of the experiment or analysis. This can usually be done by adjusting the position of the jaws using the adjustment mechanism provided.
3. Start the Crusher - Power on the laboratory jaw crusher and ensure that it is properly calibrated and operational. Follow the manufacturer's instructions for starting and operating the crusher safely.
4. Loading of Sample - Place the prepared sample material into the jaw crusher chamber. Ensure that the material is evenly distributed and does not exceed the maximum capacity of the crusher.
5. Crushing Process - Activate the crusher to begin the crushing process. Depending on the design of the crusher, this may involve manually or automatically engaging the crushing mechanism. Monitor the crusher during operation to ensure smooth and efficient crushing of the sample material.
6. Adjustment of Output Size - If necessary, adjust the output size settings of the crusher during operation to achieve the desired particle size of the crushed material. This can typically be done by adjusting the position of the jaws or by controlling the crusher's settings.
7. Collection of Crushed Material - Once the crushing process is complete, collect the crushed material from the crusher chamber. Use appropriate tools such as a brush or scraper to ensure that all crushed material is properly collected.
8. Analysis or Experimentation - Use the crushed material obtained from the laboratory jaw crusher for further analysis or experimentation as required by the specific testing requirements. This may involve conducting various tests, measurements, or analyses on the crushed material to obtain relevant data for research purposes.
9. Cleaning and Maintenance - After completing the crushing process, clean the laboratory jaw crusher thoroughly to remove any residual material or debris. Follow the manufacturer's instructions for proper maintenance and storage of the crusher to ensure its long-term performance and reliability.
