What Are ISO Standards for Monitoring Crusher Vibration?
Time:
29 July 2021
The ISO (International Organization for Standardization) has developed various standards that address vibration monitoring and related topics for industrial machinery, which can be applied to crushers. While there isn’t a specific ISO standard dedicated exclusively to crushers, the following standards are commonly referenced for vibration monitoring in rotating and industrial machinery, including crushers:
1. ISO 20816 Series: Vibration Monitoring and Evaluation of Machines
- ISO 20816-1:2016
This standard defines general guidelines for the measurement and evaluation of machine vibration by shaft and bearing measurements, applicable to machines such as crushers. It provides criteria for assessing vibration levels and identifying damage or developing faults.
- ISO 20816-2:2023
Focuses on large machines with rotating shafts, which may apply to crushers depending on their design.
- ISO 20816-3, ISO 20816-4
These parts specifically apply to different types of industrial machinery and can be valuable depending on the type and operation of the crusher.
2. ISO 10816-3:2009 (Earlier Version)
The ISO 10816 series, which has now evolved into ISO 20816, governs vibration monitoring for industrial machinery. ISO 10816-3 specifically focuses on criteria for rotating machinery, including setting acceptable vibration limits based on machine size, type, and operating conditions.
3. ISO 13373 Series: Condition Monitoring and Diagnostics of Machines
- ISO 13373-1:2016
Provides the general guidelines for vibration condition monitoring of machines, which can include large crushers used in mining and other industries. It outlines procedures for periodic and real-time monitoring, focusing on using vibration signals for fault diagnosis.
- ISO 13373-2:2020
Deals with processing and signal analysis methods for vibration data, enabling the identification of specific issues within crushers like misalignment, bearing damage, or imbalance.
4. ISO 2954: Calibration of Vibration Measuring Instruments
- Sets the criteria for vibration measuring devices used for monitoring crushers and other industrial equipment. Ensuring calibrated and accurate instruments is critical for reliable vibration analysis.
5. ISO 2372: Evaluation of Vibration
- Includes classifications for machinery based on vibration severity. Although not specific to crushers, these guidelines can help determine acceptable vibration levels for machines.
Key Considerations for Crusher Vibration Monitoring:
- Acceptance Criteria: ISO standards generally define acceptable vibration levels for various categories of machines, which can apply to crushers based on their size, operating speed, and function.
- Measurement Locations: Monitoring vibration on crushers typically involves sensors placed on bearings, shafts, and structural components to detect misalignment, wear, or excessive vibrations.
- Data Analysis: ISO standards like 13373 emphasize using vibration signatures to diagnose issues in equipment, which is critical for crushers operating under heavy loads and low speeds.
- Usage: Crushers often operate under harsh conditions (dust, impact, heavy loads), so monitoring should accommodate environmental factors.
Conclusion:
ISO standards for vibration monitoring provide applicable guidelines to assess the health and performance of crushers and other industrial machinery. While ISO 20816 and ISO 13373 are the most relevant for this purpose, you may need to refer to specific criteria based on the operational demands and crusher setup.
