The styles and functions of crushers are different, and they will be used in different crushing procedures and working conditions according to their characteristics. The main impact on the crushing efficiency of the crusher is the wear-resistant parts of the crusher, such as the jaw plate of the jaw crusher and the blow bar of the impact crusher. As we all know, the wear-resistant parts of crushers are made of high manganese steel, high chromium, ceramics and other materials. Different materials have different characteristics, which will have a certain impact on the product.
High manganese steel and high chromium are the most important materials for the production of crusher wear parts. The high manganese steel content mainly used by Shanwei Industrial Co., Ltd. is M14, M18 and M22. High-manganese steel refers to alloy steel with a manganese content of more than 10%. This type of steel contains 10%-15% manganese and a higher carbon content, generally 0.90%-1.50%. The temper of manganese steel is very weird and interesting: if 2.5-3.5% manganese is added to the steel, the resulting low manganese steel is as brittle as glass. However, if more than 13% manganese is added to make high manganese steel, it will become hard and tough. Work hardening occurs under conditions of strong impact. Therefore, high manganese steel materials are suitable for making accessories such as jaw plates, moving cones and fixed cones.
The advantages of high chromium cast iron are high hardness and good wear resistance, but the toughness is lacking compared with high manganese steel cast iron. Under high-impact conditions, the toughness is insufficient and fractures are prone to occur. Shanwei has a good control over the content of S and P elements in high chromium cast iron, which makes the performance of the finished product more excellent.
Shanvim as a global supplier of crusher wearing parts, we manufacture cone crusher wearing parts for different brands of crushers. We have more than 20 years of history in the field of CRUSHER WEAR PARTS. Since 2010, we have exported to America, Europe, Africa and other countries in the world.
