• What is the correct way to replace the main frame seat liner in cone crusher?

  May 29, 2025

  In the use of cone crushers, wear parts often need to be replaced due to damage. Today we will introduce how to correctly replace the stone crusher parts name main frame seat liner.   Many customers report that the parts of crusher machine main frame seat liner is difficult to weld on the main frame. This is mainly because they do not master the welding process. Pay attention to the following points:   1. Thoroughly clean the welding position.   2. Heat the main frame to 100 degrees before welding, and the cone crusher parts name main frame seat liner also needs to be baked to about 40-50 degrees.   3. Weld from the middle to both sides.   4. Keep warm for 1 hour after welding.   In China, the welding rod we usually use is T237 3.2mm. The following are the main parameters of the welding rod.   Aluminum-manganese bronze is a copper alloy electrode with a welding core and a low-hydrogen coating. The deposited metal contains alloys such as Al 6.5-10%, Mn≤2.0%, Cu＜90%, etc., with excellent wear resistance and corrosion resistance. A DC power supply is used, and the electrode is connected to the positive electrode. It is used for welding aluminum bronze and other copper alloys, copper alloys and steel, and repairing cast iron. Such as welding of various chemical machinery, seawater radiators, valves, surfacing welding of water pumps, cylinders, etc. and repairing of ship propellers. Before welding, the electrode needs to be baked at about 200℃ for 1h. The moisture, oil, oxides and other impurities on the surface of the weldment must be cleaned. For welding aluminum bronze and surfacing welding of carbon steel, thin parts do not need to be preheated, and thick parts must be preheated at about 200℃.

• What material is used in cone crusher liners?

  May 22, 2025

  Choosing the right cone crusher liner requires comprehensive consideration of multiple factors. How to choose crusher concave and mantle?   1. Choose according to the crusher part number Different types of cone crushers need to match specific bowl liner and mantle. For example, Metso crushers have multiple series such as MP, HP, GP, etc., and liners of different series cannot be mixed.   2. Consider the liner material The material of the cone crusher wear part liner directly affects its wear resistance and service life. Common liner materials include: High manganese steel: It has high wear resistance and impact resistance, and is suitable for processing materials with higher hardness, such as limestone and granite. In common MN13, MN18 and MN22. Modified high manganese steel: Improves wear resistance by adding alloy elements, suitable for materials with medium hardness. Chromium cast iron: High hardness, good wear resistance, but poor toughness, suitable for materials with high hardness and high abrasiveness. Such as Cr26.   When choosing the liner material, the more wear-resistant the better, it is not necessarily the better. It needs to be matched according to the hardness and crushing requirements of the material.   3. Select according to the crushing cavity type The cavity design of the crusher wear liner determines the crushing effect and efficiency of the crusher. Common cavity types include standard type, medium crushing type and fine crushing type: Standard type: Suitable for coarse crushing, with a larger crushing cavity, suitable for processing large pieces of material. Medium crushing and fine crushing type: Suitable for medium and fine crushing, with a smaller crushing cavity, which can control the particle size distribution of the material. For Each models, there are different cavity type liners such as STD, F, SH, part number or drawings are the only information to confirm the correct one. If you have part number of bowl liner, we can according it to suggest mantle.   4. Consider the service life and replacement cost of the cone crusher wear parts liner Using life: Appropriate liner material and design can extend the service life of the liner and reduce the frequency of replacement. Replacement time: When the liner thickness wear reaches 65% to 80%, or there is local depression, deformation and cracking, it should be replaced in time.   ONA will provide professional suggestions for choose correct liners, installing and using tips.
