Does the crusher liner come with a test certificate?
When Purchasing Manganese Steel Parts, it is important to consider whether the supplier can provide a test certificate. Crusher liners are not produced on automated assembly lines, so it is crucial that manufacturers adhere to consistent production standards. Suppliers should have a well-established production process and quality control, and be able to provide test certificates to validate their production standards. Duma Machinery, as a crusher Wear Parts Supplier, has obtained ISO 9001:2015 certification (latest version) for its quality management system. They commit to providing detailed test reports based on customer requirements and offering comprehensive customer service reports to address any issues that may arise during use.
Additionally, you can choose third-party testing, and the supplier will provide the following test certificates:
● Chemical composition analysis report (focusing on the carbon-to-manganese ratio and trace elements)
● 3D dimensional tolerance inspection records
● Heat treatment process curve charts
The chemical report for manganese steel parts should include the main components of carbon and manganese, as well as possible residual elements from additives or unintentional additions, especially those from recycled scrap. The crusher wear parts supplier should be able to explain the potential impact of these residual elements on the performance of manganese steel and their relationship with carbon and manganese content.
During the manufacturing process, dimensional inspection is crucial to ensure that the liners fit the crusher perfectly. If the liners do not come with a test report, you can request it from the crusher wear parts supplier when making your purchase. Although the heat treatment report can show the time and temperature during the heating process, it cannot fully prove the material's performance. Magnetic testing is an effective way to check the quality of manganese steel liners. Austenitic manganese steel should be non-magnetic, which can be tested with a magnet. After removing the surface oxide layer, check if the magnet is attracted to determine if there are heat treatment issues.
What should end users pay attention to when receiving new crusher liners?
When Purchasing Manganese Steel Parts, confirming the appearance and packaging of the crusher liners is an essential step. Newly purchased liners are usually coated with paint and neatly packaged, having a good appearance. Users can perform a simple visual inspection; if there are no obvious defects on the surface of the liners, they can be stored for future use. During the inspection, pay attention to the following points:
a). The conical liners are cast in two parts, and their inner and outer surfaces should be concentric. Ensuring these surfaces match precisely during machining can effectively avoid fitting problems when starting the crusher.
b). The part number from the crusher wear parts supplier and the casting number (furnace number) from the foundry should be marked on the non-wear surface of the liner, and match the number on the shipping delivery note. Suppliers with quality management system certification will ensure traceability from production to usage. If issues arise during the use of the liner, the end user can refer to the test report for traceability, ensuring the accuracy of the solution.
What should we provide if we want you to manufacture crusher liners for us?
Of course, the first thing is the cost, which is essential (laughs).
In fact, the information you need to provide when Purchasing Manganese Steel Parts depends on your crusher brand. If it is a branded crusher, you only need to provide the part number obtained from the crusher supplier. For example, the part number for crusher liners could be: 5520xxxx, 705520xxxxx, or 1063xxxxxxx.
If you are using a Sandvik brand crusher, the crusher liner part number could be: 442.xxxx-01, 400.xxxx-02, or 452.xxxx-01.
If your crusher was purchased from China, please provide the crusher brand and part number, or the crusher wear parts supplier can arrange to measure the dimensions and create drawings based on your requirements.
