How can high-manganese steel castings become the key to the wear resistance upgrade of impact crushing equipment?

Technical principles and advantages of high manganese steel castings

The high manganese steel castings used in impact crushers mainly include: impact plates, impact plates, lining plates, etc. These components need to withstand severe impacts and wear of high-speed materials for a long time. Ordinary alloy materials are difficult to meet the harsh working conditions of strong impact and high wear, while high manganese steel materials show excellent impact and wear resistance in actual use due to their unique self-hardening characteristics and excellent toughness.
During the working process, high manganese steel (usually refers to austenitic manganese steel with a manganese content of between 10% and 14%) will work harden when subjected to strong impact force, that is, a dense hardening layer is formed under the action of external forces, effectively improving the surface hardness of the material (can reach HB500 or above), while the interior still maintains good toughness and plasticity, thereby achieving the ideal structure of "hardness and softness". Because of this, high manganese steel castings are not only not easy to break during repeated impact and severe friction, but also become more wear-resistant as they are used.

Core components include, but are not limited to:
Counterattack plate: Enhanced secondary crushing, optimized particle type control
The impact plate is located at a key position in the crushing chamber and is the core component to achieve the "secondary impact crushing" of the material. When the rotating rotor at high speed throws out the material, the impact plate is responsible for receiving the rebound and completing the process of re-crumbing, thereby improving the crushing efficiency and consistency of the discharge particle type. After using high manganese steel, the impact plate can form a hardened layer under continuous impact, effectively improving wear resistance, and retaining good toughness inside to prevent breakage. Its reasonable structural design also facilitates the adjustment of angles to meet different crushing needs.
Strike plate: the primary force point, carrying strong impact energy
The strike plate is directly installed on the rotor, which is the area where the material first hits at high speed, and bears a huge instantaneous impact force. It is one of the most severely worn parts in the crushing system. With its excellent self-hardening ability and high toughness characteristics, high manganese steel strike plates can still maintain the structural integrity under high frequency impact, delay fracture and deformation, and ensure continuous and efficient crushing process. Its strength design not only ensures the crushing effect, but also reduces maintenance frequency and downtime.
Lining plate: protects the body structure and improves the durability of the whole machine
The lining plate is mainly arranged on the inner wall of the crushing cavity, which plays a role in protecting the equipment body and reducing material impact. In daily operation, materials come into contact with lining plates frequently. If the material is not wear-resistant, it is very easy to cause wear of the equipment shell. High manganese steel linings have excellent performance in resisting scouring and abrasion due to their characteristics of hard outer layer and tough core. Its modular structure is easy to replace and repair, and it also works in concert with the impact plate and the impact plate to effectively maintain the stable stress structure in the crushing chamber and optimize the crushing efficiency.
As key components of high manganese steel castings, the impact plate, the impact plate and the lining plate cooperate with each other in actual crushing operations to form a complete and efficient crushing system. They jointly undertake impact load, wear stress and earthquake resistance functions, greatly improving the overall performance and reliability of the equipment. At the same time, the ease of replacement and high adaptability of these components also brings lower maintenance costs and higher running time to users, which is a solid guarantee for the high-performance operation of impact crushing equipment.

Wide range of applications and excellent practical performance

High manganese steel castings for impact crushers have been widely used in many industries:
Mine crushing: treat high hardness rocks such as granite, basalt, iron ore, etc.
Construction waste treatment: realize the resource utilization of solid waste such as concrete blocks, bricks and tile blocks
Cement building materials: crushed limestone, gypsum, clinker and other raw materials
Chemical raw material crushing: improve the processing efficiency of medium-hard mineral raw materials
These operating scenarios generally have the characteristics of strong impact, large dust and harsh environment, which puts high requirements on the strength and wear resistance of equipment components. With its excellent wear resistance and long life, high manganese steel castings not only reduce frequent replacement due to component losses, but also greatly reduce equipment maintenance costs and unplanned downtime, saving enterprises a lot of operating costs.
