The side guard plate is made of high manganese steel alloy containing 11-14% manganese (Mn), 0.9-15% silicon (Si), 0.4-1.0% chromium (Cr), and trace amounts of phosphorus (P), nickel (Ni), copper (Cu) and molybdenum (Mo). The precise ratio of these alloy components ensures that the side guard plate has good hardness, toughness, and wear resistance.The design of the side guard plate takes into account that its main function is to protect the body of the crusher from material impact. Therefore, designers usually optimize its shape, thickness, and surface treatment to ensure protection during long-term use. When designing, the side guard plate usually adopts a thicker structure to enhance impact resistance, and the edges and contact areas may adopt a reinforced design to withstand high-intensity wear and impact. In addition, the addition of chromium and silicon further improves the corrosion resistance of the steel, allowing the side guard plate to maintain good performance in complex environments, especially when wet or containing corrosive materials.
