Introduction
Introduction: Importance and Background of Remanufacturing of Crushing Equipment
With the increasing global attention to efficient resource utilization and environmental protection, the remanufacturing technology of crushing equipment is particularly important. This standard provides detailed technical specifications to guide the remanufacturing of waste or old crushing equipment, aiming to promote the development of green manufacturing and reduce resource waste and environmental pollution.
Comparative Analysis of Standard Frameworks
| Dimensions | Original Standard (JB/T) | New Standard (GB/T 37887—2019) | Difference Analysis |
|---|---|---|---|
| Technical Requirements | Mainly covers basic maintenance and repair of equipment. | Expanded to the comprehensive remanufacturing process, including design, disassembly, testing, etc. | The new standard introduces the concept of green manufacturing and detailed quality management requirements. |
| Scope of application | Limited to specific types of crushing equipment. | Applicable to various crushing equipment, including jaw type, impact type and other diversified types. | The new standard has a wider applicability and covers more types of equipment. |
| Environmental requirements | No clear environmental protection requirements. | Emphasis on green manufacturing, and specific measures and requirements for environmental protection. | Introduced new content such as resource utilization efficiency and energy efficiency analysis. | \n
Technical Requirements Interpretation
According to the standard, the remanufacturing process includes steps such as disassembly, classification, cleaning, and testing of the equipment. In particular, for core components such as shafts, gears, and bearings, non-destructive testing is required and advanced processes such as laser repair technology are used for repair.
Actual Application Case: Remanufacturing of Jaw Crusher
In an industrial project, a jaw crusher of a certain enterprise deteriorated in performance due to long-term use. According to the standard requirements, after the equipment was disassembled, each component was strictly tested and classified. For key components such as rotors and bearings, laser cladding technology was used for repair, and all seals and fasteners were replaced. In the end, the remanufactured crusher not only restored its original performance, but also improved its energy efficiency by 15%.
Implementation Suggestions
- Establish a quality management system: Ensure that the remanufacturing process complies with the requirements of GB/T31207, especially for the management of updated and recycled parts.
- Technical training: Provide detailed standard interpretation and application training of advanced technologies (such as laser repair) for operators and technicians.
- Supply chain optimization: Cooperate with high-quality suppliers to ensure that the quality of all replacement parts meets or exceeds the original equipment standards.
- Data records: Maintain complete inspection and maintenance records to facilitate traceability and evaluation of remanufacturing results.
