A Few Tips for Selecting Wear-Resistant Manganese Steel Spare Parts for Crushers
2025-04-01
Do you have a crusher liner test certificate?
When selecting crusher parts, whether the supplier can provide test certificates is an important consideration. Crusher liners are not produced on automated assembly lines; therefore, it is crucial for manufacturers to adhere to consistent production standards to ensure reliability for users. Crusher wear-resistant component suppliers must have well-established production processes and quality control systems, and they should be able to offer test certificates that verify their adherence to these rigorous standards. Duma Machinery, as Wear-resistant manganese steel parts for crushers The supplier, certified under the ISO 9001:2015 Quality Management System (new version), commits to providing detailed test reports upon request and delivering comprehensive customer service reports to assist in resolving any issues that may arise during use.
Additionally, you can also opt for third-party testing; the supplier will provide you with the following test certificates:
● Chemical Composition Analysis Report (with emphasis on verifying the carbon-manganese ratio and trace elements)
● 3D Dimensional Tolerance Inspection Record
● Heat Treatment Process Curve Diagram
The chemical report for manganese steel parts should include the main components of carbon and manganese, and may also address residual elements added intentionally or unintentionally—particularly those originating from recycled scrap materials. Wear-resistant manganese steel parts for crushers Suppliers should be able to explain the potential impact of these residual elements on the performance of manganese steel, as well as their relationship with carbon and manganese content.
During the manufacturing process, dimensional inspection is crucial to ensure that the lining plates perfectly fit the crusher. If the lining plates do not come with a test report, you can request one when making your purchase. Wear-resistant manganese steel parts for crushers Suppliers are requested to provide the heat treatment report, which, while detailing the time and temperature during the heating process, does not fully guarantee the material's performance on its own. To effectively assess the quality of manganese steel liners, magnetic testing can be employed: austenitic manganese steel should be non-magnetic, and this can be verified by using a magnet. After removing any surface oxide layers, simply check whether the magnet adheres to the material—this will help determine if there are any issues related to the heat treatment process.
What should users pay attention to when receiving new crusher liners?
When selecting crusher parts, confirming the appearance and packaging of the crusher liners is an essential step. Newly purchased liners are typically coated with paint and neatly packaged, presenting a well-maintained appearance. Users can perform a simple visual inspection—if the liner surface shows no obvious defects, it can be stored for future use. During the inspection process, pay attention to the following points:
a. The tapered bushing is cast in two parts, and its inner and outer surfaces should be concentric. By machining to ensure these surfaces precisely match, you can effectively prevent fitting issues during startup.
b. Wear-resistant manganese steel parts for crushers The supplier's part number and the casting plant's casting number (furnace number) should be marked on the non-wearing surface of the liner plate, matching the numbers listed on the accompanying delivery note. Suppliers certified under a quality management system will ensure full traceability of the liner plates—from production through to their use. Should any issues arise during the liner plates' operation, users can refer to the test reports to accurately trace the root cause, guaranteeing the effectiveness of the solution.
If we want you to manufacture crusher liners, what should we provide?
Of course, first comes the cost—something that’s absolutely essential (laugh).
In fact, the information you need to provide when purchasing crusher parts depends on the brand of your crusher. If it’s a branded crusher, simply supply the part number obtained from your crusher supplier. For example, crusher liner part numbers could be: 5520xxxx, 705520xxxxx, or 1063xxxxxxxxx.
If you are using Sandvik-brand crusher liners, the part numbers may be: 442.xxxx-01, 400.xxxx-02, or 452.xxxx-01.
If your crusher was purchased from China, please provide us with the crusher brand and part number, or Wear-resistant manganese steel parts for crushers Suppliers can arrange for measurements and prepare drawings according to your requirements.
