Is there a test certificate for the crusher liner?

When purchasing crusher parts, whether the supplier can provide a test certificate is an important consideration. Crusher liners are not produced on automated assembly lines, so it is crucial for manufacturers to follow consistent production standards. Suppliers of crusher wear parts need to have complete production processes and quality control, and be able to provide test certificates to verify their production standards. Dumamachinery, as a Crusher wear-resistant manganese steel parts supplier, has obtained ISO 9001:2015 Quality Management System Certification (new version), and is committed to providing detailed test reports upon request, and providing comprehensive customer service reports to users to help solve any problems that may arise during use.

In addition, you can also opt for third-party testing, and the supplier will provide you with the following test certificates:

● Chemical composition analysis report (focus on checking carbon-manganese ratio and trace elements)

● Three-dimensional size tolerance inspection record

● Heat treatment process curve chart

The chemical report for manganese steel parts should include the main components of carbon and manganese, and may also involve residual elements added as additives or unintentionally, especially those from recycled scrap materials. Crusher wear-resistant manganese steel parts The supplier should be able to explain the potential impact of these residual elements on the performance of manganese steel, and their relationship with the carbon and manganese content.

During the manufacturing process, dimensional inspection is crucial to ensure that the liner fits the crusher perfectly. If the liner does not come with a test report, you can request it from the supplier at the time of purchase. Although a heat treatment report can show the time and temperature during the heating process, this report alone cannot fully prove the material's performance. Magnetic testing can effectively detect the quality of manganese steel liners; austenitic manganese steel should be non-magnetic. You can test it with a magnet: after removing the surface oxidation layer, check if the magnet adheres to determine if there is a heat treatment problem.

When selecting crusher parts, confirming the appearance and packaging of the crusher liner is an essential step. Newly purchased liners are usually painted and neatly packaged, with a good appearance. Users can perform a simple visual inspection; if there are no obvious defects on the liner surface, it can be stored for later use. During the inspection process, pay attention to the following points:

a. The tapered bushing is cast in two parts, and the inner and outer surfaces should be concentric. Ensuring these surfaces match precisely through machining can effectively avoid fitting problems during startup.

b.

The supplier's part number and the foundry's casting number (heat number) should be marked on the non-wearing surface of the liner and match the number on the delivery order. Suppliers with quality management system certification will ensure the traceability of the liner throughout its entire process from production to use. If a problem occurs with the liner during use, users can refer to the test report to trace the problem and ensure the accuracy of the solution.

Of course, first of all, the cost, which is essential (laughs).

Actually, when purchasing crusher parts, the information required depends on your crusher brand. If it's a branded crusher, you only need to provide the part number obtained from the crusher supplier. For example, the crusher liner part number might be: 5520xxxx, 705520xxxxx, 1063xxxxxxx.

If you are using a Sandvik brand crusher liner, the part number might be: 442.xxxx-01, 400.xxxx-02, 452.xxxx-01.

If your crusher was purchased from China, please provide us with the crusher brand and part number, or

The supplier can arrange to measure dimensions and create drawings according to your requirements.
