AGICO Crusher Jaw Plate
Jaw plates, also known as tooth plates, are critical wear-resistant components in jaw crushers. A set of jaw plates consists of a fixed jaw plate and a movable jaw plate. These two jaw plates are respectively located on the moving jaw and the fixed jaw within the crushing chamber. When the crusher is in operation, the material is crushed by the mutual squeezing of the moving jaw and the stationary jaw.
Jaw crushers are one of the most commonly used crushing equipment in the cement industry and mining operations. They are typically used for primary crushing in production lines. The materials crushed by jaw crushers have the highest hardness and largest particle size in the entire process. Therefore, the wear of components, especially jaw plates, is significant. As the crushing part, jaw plates directly contact the material, making them prone to wear. Hence, the quality of jaw plates is crucial. Good-quality jaw plates can improve crushing efficiency, reduce failure rates, decrease component replacement frequency, and save maintenance costs.
Different models of crushers require jaw plates of varying sizes and styles. As an experienced machinery manufacturer, AGICO CEMENT can customize and process suitable jaw plates based on the client’s crusher model or provided drawings. AGICO jaw plates undergo scientific and rigorous smelting, casting, heat treatment process design, and research and development management. They exhibit excellent comprehensive performance, high reliability, strong wear resistance, low price, and high cost-effectiveness. We welcome customers worldwide to contact us for inquiries.
AGICO Jaw Plates Advantages
Scientific Material Selection: We use high-quality manganese steel as the base material and employ advanced material chemical composition design, ensuring that our crusher jaw plates have excellent toughness and good deformation hardening capability.
Fine Craftsmanship: The entire process follows a strict scientific approach, from smelting, casting, heat treatment to quality inspection, ensuring superior product quality and durability.
Advanced Technology: We utilize cold working hardening technology to continuously enhance the hardness of the jaw plates under pressure. At the same time, we employ world-leading full welding structure technology and advanced post-treatment techniques to improve the stability and smoothness of the jaw plates.
Economic Benefits: Compared to ordinary jaw plates, our manufactured jaw plates have stronger wear resistance and longer service life. Not only are they safer and more reliable, but they also improve crushing efficiency and reduce maintenance costs, thereby delivering higher economic benefits to our customers.
Jaw Plate Materials
The jaw plates manufactured by our company primarily utilize composite materials based on high manganese steel. High manganese steel is the traditional material for jaw crusher jaw plates, known for its excellent toughness and good deformation hardening capability. The material options include Mn13, Mn13Cr2, Mn18Cr2 (also known as ultra-high manganese), or special compositions based on working conditions.
To improve the service life of the jaw plates, our company has developed multiple material options. For instance, we incorporate elements such as Cr, Mo, W, Ti, V, Nb, etc., to modify high manganese steel, thereby enhancing its initial hardness and yield strength. Additionally, we have conducted dispersion strengthening treatments on high manganese steel. Furthermore, we have developed composite jaw plates composed of medium manganese steel, low-alloy steel, or high-chromium cast iron combined with high manganese steel, all of which have shown excellent performance in practical applications.
Material Selection Recommendations for Jaw Plates
Ideally, the material selection for jaw crusher jaw plates should meet the requirements of high hardness and high toughness. However, toughness and hardness of materials often pose a contradiction. Therefore, in practical material selection, AGICO CEMENT takes into full consideration the customer’s crushing materials and operating conditions, or based on customer requirements, selects the most suitable material.
Impact load is one of the important factors to consider in rational material selection.
As the size of the crusher increases and the wear parts become heavier, the crushing materials tend to have larger particle sizes, resulting in higher impact loads on the jaw plates. In such cases, modified or dispersion-strengthened high manganese steel can be considered.
For medium and small-sized jaw crushers, where the impact load on the wear parts is not significant, it is challenging to achieve full work hardening with high manganese steel. Under such operating conditions, using medium carbon low-alloy steel, high-chromium cast iron, or low-alloy steel composite materials can achieve good technical and economic benefits.
The composition and hardness of the materials are also crucial factors in rational material selection.
Generally, the higher the hardness of the material, the higher the hardness requirement for the wear parts material. Therefore, while meeting toughness requirements, materials with high hardness are preferred whenever possible.
Rational material selection should also consider the wear mechanism of the wear parts.
If the wear mechanism is primarily cutting wear, hardness should be the primary consideration in material selection. If the wear mechanism is primarily plastic deformation wear or fatigue wear, plasticity and toughness should be considered first.
