Jinan, Shandong Sheng Apr 8, 2026  – Bangde Heavy Industry Technology Co., Ltd., a leading integrated mechanical engineering enterprise, released a full research report on factors influencing wear resistance of core crushing equipment components. The study focused on jaw plates, whose durability directly determines the operational efficiency of mining and construction activities.

The research highlights that wear resistance is not a static material attribute, but comes into being through the complex interaction of an alloy’s chemical composition, thermal strengthening parameters, and dynamic working conditions.

Analysis of Factors Impacting Component Wear

The surface failure process of jaw plates in jaw crushers is driven by multiple factors. Specialists from Bangde Heavy Industry have identified three core aspects that need to be considered during component design and manufacturing:

Intensity and type of impact loads: When processing high-strength rocks such as granite or basalt, components face cyclic impact loads repeatedly. High-manganese steel delivers the best performance under these conditions. Impacts alter the material’s crystal lattice structure, leading to surface work hardening, while the inner part of the part retains its ductility to avoid brittle fracture.
Abrasive hardness of the processed material: The hardness of the rock being crushed decides the rate of micro-cutting on the plate surface. To minimize wear, the working layer must reach a specific hardness threshold. This requires precise selection of alloying elements including chromium, molybdenum, and nickel, which form hard carbides during the heat treatment process.
Size and kinematic characteristics of crushing equipment: Large equipment generates much higher specific pressure in the crushing chamber. Such machines require materials with higher yield strength. A mismatch between material strength and equipment scale will lead to plastic deformation (“yielding”) of the plates, which disrupts the geometric structure of the crushing chamber and lowers productivity. Technical Methods for Enhancing Wear Resistance

In modern metallurgical practice, several key directions have been proven to effectively extend the service life of wear parts significantly.

Application of Composite and Bimetallic Structures

One of the most effective solutions is the production of composite plates. This technology combines properties that are rarely found in a single monolithic alloy: ultra-high hardness and excellent impact toughness.

Steel-Cast Iron Composite: This solution uses high-manganese steel as the base and high-chromium cast iron as inserts. The cast iron provides abrasion resistance, while the steel matrix holds the inserts firmly and absorbs impact energy.

Bimetallic Castings: A sequential pouring or explosive welding technology that forms a permanent bond between two layers with different physical and chemical properties.

Surface Hardening and Microstructure Adjustment

In addition to overall hardening, localized hardening methods are adopted for areas that suffer the most severe wear:

Laser cladding: A modern technique that applies wear-resistant powders with the support of a laser beam. It ensures minimal mixing of the deposited material and the base material, as well as ultra-high adhesion strength.

Wear-resistant weld layer: Specialized electrodes are used in the riveting and welding workshop for surface repair or pre-protection.

Chemothermal treatment: Adjustment of the surface layer composition through diffusion saturation with elements that can improve microhardness.

Geometric Shape and Structural Optimization

Bangde Heavy Industry’s design department optimizes the tooth profile and plate thickness distribution. Reasonable metal mass distribution helps compensate for uneven wear, which is usually concentrated in the lower part of the crushing chamber. Shape optimization also enables materials to move downward more smoothly, reducing the time they rub against the plate surface.

Production Capacity and Full Process Chain

Implementing high-tech solutions for wear-resistant materials is only feasible with a complete production chain. Bangde Heavy Industry’s plant infrastructure is built as a closed-loop ecosystem, covering all production stages from raw material smelting to final finishing.

Foundry Workshop and Smelting Facilities: The plant is equipped with high-capacity melting units, including two 15-ton and two 3-ton electric furnaces. This enables the production of complex castings with accurate chemical composition. The maximum casting processing capacity reaches 80 tons, which meets the demand of the largest crushing equipment models.

Machining and Assembly: The company’s equipment fleet totals 121 units, including:

36 sets of intelligent foundry equipment;

59 sets of equipment

Riveting and welding facilities;

26 sets of precision machining equipment. Crane systems with a maximum lifting capacity of up to 100 tons are used for transporting and positioning ultra-heavy parts.

Research and Development Facilities and Quality Control. The complex includes a separate dedicated building for research and development (R&D). New alloy testing and metal macrostructure analysis after various heat treatments are carried out here. An on-site thermal power plant ensures the company’s energy independence and stable production processes, which is critical for maintaining the required temperature schedules for steel quenching and tempering.
