The liner is the main part of the cone crusher crushing process, and it is also the * easily worn part. If the liner wears more severely, it will affect the overall working of the crushing chamber, so it is also very important to pay attention to the quality of the liner when buying a cone crusher. of. The following introduces you the manufacturing process of Zhongxin Lining Board.     1. The choice of liner material. Our company’s cone crusher liner material is made of wear-resistant high-manganese steel. After testing, the initial hardness can reach about B260. The wear resistance is excellent, which is very conducive to the processing of materials with higher hardness.
    2. The process of material processing. In order to further improve the wear resistance of high manganese steel materials, we usually add alloy elements, but if the carbon element in the alloy is too high, it will reduce the wear resistance, so the refining of alloy materials is also very important. In the processing, the time and temperature of the water entering and exiting should be strictly controlled to make all the indicators meet the national requirements.
    3. Strict control of casting process. This is not the check of the lining technology of the cone crusher, but also the check of the entire machine and equipment technology. We all know that the wall of the liner of the cone crusher is thick and large. The thickness can reach 200mm. If the casting temperature is not reached, the grain of the high manganese steel liner will be larger, which will shorten the use of the liner. Life, so our company uses metal sand coating in the casting process, which effectively reduces the pouring temperature, refines the grain of the liner, and achieves the purpose of extending the service life of the liner.
    Years of experience in the production of cone crushers have enabled us to focus on the production of every detail of the equipment. The quality of Zhongxin Heavy Industry's equipment is obvious to all. Welcome to inquire.
