Description

The fixed jaw plate is a crucial component of the jaw crushing station's main machine. It is responsible for directly coming into contact with materials during operation and therefore, is highly susceptible to wear and tear. As the jaw plate constantly endures the crushing and grinding forces of the materials, its crushing teeth face considerable strain and can easily become worn out under heavy loads. Safeguarding the durability and functionality of the fixed jaw plate is essential for maintaining the efficient operation of the jaw crushing station.

 

The market offers a wide range of jaw plate materials, and the choice of material depends on the duration of use for crushing different materials and the efficiency of jaw crushing stations. Let's explore the different types of jaw plates available in the market along with their respective characteristics.
When it comes to jaw plates, there is no shortage of options. Manufacturers provide a variety of choices suited for specific crushing requirements. The material selection greatly influences the overall performance and durability of the jaw plates.
One commonly used material for jaw plates is manganese steel. Manganese steel jaw plates are known for their exceptional strength and toughness. They can withstand high impact and abrasive forces, making them suitable for crushing hard and abrasive materials. However, over time, manganese steel jaw plates may wear down, affecting their performance and crushing efficiency.
Another material option is chromium steel, which offers excellent resistance to wear and corrosion. Chromium steel jaw plates have high hardness and toughness, making them ideal for crushing materials with high compressive strength. They provide good wear resistance and can handle moderate impact forces, ensuring prolonged service life.
For applications where non-abrasive materials are being crushed, a choice of jaw plates can be made from high carbon steel. These jaw plates are economical, offering satisfactory strength and hardness. However, they might not be suitable for extensive use with abrasive materials as they can wear down relatively quickly.
Alternatively, jaw plates made from composite materials such as high manganese steel combined with tungsten carbide inserts are available. These composite jaw plates offer enhanced wear resistance, making them suitable for crushing extremely abrasive materials. The tungsten carbide inserts provide additional hardness and reinforcement to the jaw plates, extending their lifespan.
In conclusion, the market offers various jaw plate materials, and the selection depends on the specific crushing requirements. Each material has its own advantages and limitations in terms of toughness, hardness, wear resistance, and cost-effectiveness. Proper selection of jaw plates is crucial to ensure efficient and long-lasting operation of jaw crushing stations.

 

Fixed jaw plates for jaw crusher parts are typically fabricated from a range of robust materials such as high manganese steel alloy, medium carbon low alloy cast steel, or high chromium cast iron. These materials offer exceptional durability and strength, ensuring the jaw crusher parts can withstand heavy use and harsh operating conditions. The selection of materials is a critical factor in achieving superior performance for the jaw crusher, and careful consideration is required to ensure optimal suitability for the intended application. Regardless of the material chosen, the fixed jaw plate must be manufactured to precise specifications to ensure proper fit and function within the jaw crusher assembly.

 

The jaw plate of the jaw crusher station requires a material that can withstand impact loads, and high manganese steel has been the go-to choice for decades. High manganese steel is a type of alloy steel that contains at least 10% manganese. National standards have categorized it into five grades, with the carbon content being the main differentiator. Essentially, the lower the carbon content, the better its ability to resist impact forces and vice versa.

 

High chromium cast iron is known for its high wear resistance, but it is not ideal when it comes to toughness. Thus, using high chromium cast iron alone may not yield favorable results as a jaw plate. However, when it is utilized as a casting or bonding material onto high manganese steel jaw plates, the result is a composite jaw plate with relatively high wear resistance. Such a combination significantly extends the jaw plate's service life. Nevertheless, producing such a composite jaw plate demands a more complex and difficult manufacturing process, making its cost higher.

 

When it comes to wear resistance, medium carbon low alloy cast steel is a tough customer. This material can hold up against repeated extrusion and material cutting, without succumbing to fatigue peeling. In comparison to high manganese steel, medium carbon low alloy steel jaw plates have a longer service life - up to three times longer! On the other hand, the toughness of this material is just average. Testing during production operations has proven the benefits of using this type of steel, as it offers a solid alternative to high manganese steel.
