Ball mill liners Features: high manganese biggest feature has two: one is the greater external impact load, the higher the surface wear resistance of its own; the second is the gradual wear of the surface-hardened layer, a new hardening layer will continuous form. The greatest feature of high-manganese steel is twofold: First, the greater the external impact load, the higher the surface wear resistance of its own; Second, with the surface-hardened layer gradually wear large crusher, a new hardening layer NdFeB magnetic NdFeB block of wood crusher, as the latest results of the development of rare earth permanent magnet material, because of its excellent magnetic properties and are called "Magneto." NdFeB magnetic material is an alloy of praseodymium neodymium metal ore crusher, boron, iron and the like. Also known as magnet. NdFeB has high energy product and coercive force, while the advantages of high energy density make NdFeB been widely used in modern industrial and electronic technology, so that the instrumentation, electro-acoustic motors, magnetic magnetization and other equipment of small, lightweight, thin as possible. NdFeB advantage is cost-effective crusher, with good mechanical properties; downside is that the low point of the Curie temperature, the temperature characteristics are poor, and easy-powder corrosion, must make it by adjusting the chemical composition and surface treatment method adopted to improve in order to meet the requirements of practical application.
