Jaw Plate

crusher jaw plate description

AGICO CEMENT actively offers jaw dies, cheek plates, and hardware for the continued replacement of jaw crushers plate.
Jaw dies are offered in several ranges of metallic compositions and teeth profiles to meet the needs of any and all jaw-crushing applications.
By pairing our customers with the correct jaw set for their application the spare parts offered are known and proven to consistently outlast other products on the market today.

Jaw Plates or Jaw Dies are the most frequently replaced worn parts of the jaw crusher, so the quality of the jaw die is one of the most important factors that determine the crushing efficiency and operating time.

A set of jaw plates are composed of the movable (swing jaw) and fixed jaw plate (stationary jaw).
Compression of material undergoing crushing in a jaw crusher is achieved when the movable jaw dies presses the feed against the fixed jaw die.
The rock remains in the jaw of the crushing machine until it is small enough to pass through the gap toward the bottom of the jaws.

crusher jaw dies features

Efficient crushing

One of the main functions of the jaw plate is to provide efficient crushing operations. They work by applying pressure and friction to the raw material, crushing the bulk material into the required smaller particles during the movement of the crusher. This highly efficient crushing process converts the raw material into the desired size and shape quickly and efficiently.

Abrasion resistance

Jaw plates are subjected to high-intensity wear and impact during crushing and material handling. To meet these challenges, the jaws are manufactured from high-strength materials, such as high-alloy steel or manganese steel, to provide excellent wear resistance. This allows the jaws to withstand long hours of work and repeated material wear, extending service life and reducing maintenance costs.

Exact fit

The jaws are designed and manufactured for an exact fit to the crusher. They are precisely sized and geometrically shaped to ensure a perfect fit for the specific model and specification of the crusher. An accurate fit not only helps to increase the efficiency of the crusher but also reduces wear and energy loss, providing more stable and reliable operation.

Shock Resistance

Jaws provide excellent shock resistance when handling hard materials and shock loads. They are able to withstand high-intensity impact and pressure, ensuring that they are not easily deformed or broken during the crushing process. This impact resistance enables the jaw plate to handle materials with different hardness and impact characteristics, adapting to a variety of application scenarios.

Adjustable Settings

Some jaws have adjustable settings that allow the user to adjust to specific needs and application scenarios. For example, the output size and output of the crusher can be controlled by adjusting the spacing and angle of the jaw plates. This flexibility and adjustability make the jaw suitable for different types of crushing tasks and material handling requirements.

Crusher jaw plate material and manufacture

Material selection

Jaw plates are usually made of high-strength materials, the most common of which are high-alloy steels and manganese steels.
These materials have many advantages that make them ideal for jaw plate manufacturing.

  • High Alloy Steel: High alloy steel has excellent wear resistance and impact resistance.
    They are composed of steel alloys containing various alloying elements such as chromium, nickel, molybdenum, etc., which are added to increase the hardness and strength of the material.
    High-alloy steel jaws are suitable for handling harder materials and applications with high-impact loads.
  • Manganese Steel: Manganese steel is a material with excellent wear resistance and high toughness.
    Due to its high manganese content, the manganese steel jaw plate can resist abrasion and impact, and maintain good strength and toughness during the crushing process.
    Manganese steel jaws are widely used in the processing of medium-hard materials and occasions require high wear resistance.

Manufacturing process

Jaw plates are usually manufactured by casting or forging methods, depending on the material and product requirements.

  • Casting: Jaw casting is the process by which molten metal material is poured into a prefabricated mold, then cooled and solidified to form the jaw.
    This manufacturing process can accommodate complex jaw plate shapes and internal structures and has high efficiency in mass production.
  • Forging: The forging of the jaw plate is the process of heating the metal material to a high-temperature state, and then plastically deforming and forming it under pressure.
    Forging can increase the density and mechanical properties of the jaw plate, increasing its strength and durability.
    This manufacturing process is suitable for occasions that require high performance and quality of the jaw plate.

Installation Guide

  • Preparation: Before installing the jaw plate, ensure that the crusher and related equipment have been properly shut down and that appropriate safety measures have been taken.
    Clean and inspect the crushing chamber to make sure there are no residues or impurities.
  • Check The Size and Fit: Make sure the size of the jaw matches the size and model of the crusher.
    Check whether the mounting holes and fixing bolt holes of the jaw plate correspond to the equipment, and ensure that the jaw plate can be installed correctly.
  • Installation Process: According to the installation guide provided by the manufacturer, place the jaw plate in the correct position.
    Using proper tools and methods, ensure that the jaws are securely fastened to the crusher and are not loose or moving.
  • Adjustment and Inspection: Once installed, inspect the jaws for correct position and alignment.
    Make adjustments as needed to ensure proper fit and function of the jaws with other components.

Maintenance advice

  • Regular Cleaning: Regularly clean the surface of the jaw plate and the inside of the crushing cavity to remove accumulated materials and impurities.
    Cleaning with proper tools and cleaning agents ensures that the jaws remain clean and in good working order.
  • Lubrication and Maintenance: According to the manufacturer’s recommendation, regularly lubricate the key parts of the jaw plate.
    Use the proper lubricant and follow the correct lubrication method and cycle to ensure smooth operation and extended life of the jaw.
  • Regular Inspection and Replacement: Regularly check the degree of wear and damage to the jaw plate.
    If excessive wear, cracks, or other damage is found, replace the jaw plate in time to avoid further damage and reduce crushing efficiency.
  • Watch Out For Abnormal Operation: Always keep an eye on the operation of the crusher, especially for abnormal sounds, vibrations, or temperature increases associated with the jaws.
    If abnormal conditions are found, stop the machine for inspection in time, and make necessary repairs and adjustments.

Solutions To Common Problems

  • Uneven Jaw Wear: May be caused by uneven material distribution or incorrect jaw installation.
    Readjust the material distribution or reinstall the jaws to ensure an even distribution of crushing forces.
  • Cracking or Breaking of The Jaw Plate: it may be caused by overload operation, excessive hardness of the material, or material problems of the jaw plate.
    Take measures according to the specific situation, such as adjusting operating parameters, selecting appropriate jaw plate materials, etc.
  • Loose or Displaced Jaw Plate: It may be caused by loose jaw plate fixing bolts or excessive vibration of the crusher.
    Regularly check and tighten the jaw plate fixing bolts to ensure their stability and safety.
