    What role does a mortar wall play in a crusher?

    What is a mortar wall?

    I. Definition and structural positioning of the mortar wall
    The mortar wall is the core wear-resistant component in the cone crusher, also known as the “fixed cone liner”. It is installed on the inner wall of the fixed cone (fixed cone) of the crusher. It is annular or curved, and forms a crushing chamber with the “crushing wall” (moving cone liner) on the moving cone. Its surface is usually designed with uneven corrugated or toothed structures to enhance the extrusion and grinding effect on the ore.

    II. Specific role in the crusher
    Core crushing function
    When the crusher is working, the moving cone rotates eccentrically around the axis of the fixed cone. After the ore enters the crushing chamber, it will be crushed by the extrusion, impact and grinding between the mortar wall and the crushing wall.
    The curved surface structure of the mortar wall guides the ore to move downward, and at the same time, the ore particle size is gradually reduced through repeated extrusion until it is discharged from the bottom.

    Wear-resistant and impact-resistant protection
    The ore crushing process will generate strong impact and friction. As a component that directly contacts the ore, the mortar wall needs to withstand high-load wear. Its wear-resistant materials (such as high manganese steel and high chromium cast iron) can effectively extend the service life and reduce the frequency of equipment maintenance.
    Control the crushing particle size
    The gap between the mortar wall and the crushing wall (i.e. the size of the discharge port of the crushing chamber) determines the particle size of the final product. By adjusting the installation position of the mortar wall or replacing lining plates of different specifications, the coarseness and fineness of the crushed product can be controlled to meet different process requirements.

    III. Typical application scenarios
    Mortar walls are widely used in the crushing process of mining, metallurgy, construction aggregates and other industries, especially for processing granite, iron ore, basalt and other ores with higher hardness. For example:
    In the open-pit mine crushing production line, the cone crusher with the mortar wall can crush large pieces of ore into medium particle size to prepare for the subsequent grinding process;
    In the production of construction sand and gravel, crushed stone aggregates of different specifications can be produced by adjusting the mortar wall parameters.

    The jaw plate of the jaw plate crusher is referred to as the jaw plate. The jaw plate is divided into a fixed jaw plate and a movable jaw plate. It is a wear-resistant part of the jaw crusher. In the operating state of the jaw crusher, the movable jaw is attached to the movable jaw to make a compound pendulum movement, forming an angle with the fixed jaw to squeeze the stone. Therefore, the jaw plate is a more easily damaged accessory (abbreviated as: vulnerable part) in the jaw crusher.

    Classification: Fixed jaw and movable jaw
    Composition: The composition of the working cavity composed of moving and fixed jaws
    Jaw plate is the main wear-resistant part of the jaw crusher: the movable jaw plate and the static jaw plate.

    Jaw Plate Crusher
    Jaw Plate Crusher Jaw Plate Design:

    In the design, the crushing plate of the movable and fixed jaws should be tooth peak to tooth valley. Addition to the squeezing effect, the material has a bending effect when crushing the material, and the material is relatively easy to be broken.

    In order to strengthen the service life of the crushing plate, the crushing plate of the small and medium-sized crusher is designed to be symmetrical up and down, and the head can be adjusted when the lower part is worn; the crushing plate of the large jaw crusher is designed to be symmetrical to each other, so that it can be worn after wear. Replace the broken plate
    The material of the crushing plate can be white cast iron. White cast iron has higher hardness, better wear resistance, easy source, and low price; the disadvantage is that it is brittle, easy to break, and has a short service life. Order to improve the service life of the crushing plate, it is better to use manganese steel with a manganese content of more than 12%, and ZGMn13 is commonly used.

    The toughness of manganese steel is better.

    Although the hardness is not high (about 210 HB), but because of the characteristics of cold work hardening, it will continue to be strengthened under pressure, so it will continue to wear and strengthen during work until it is worn out. Use it to be scrapped.

    After casting, the manganese steel crushing plate must be treated with water toughening. Operation of the water toughening treatment is basically the same as that of quenching, that is, the cast manganese steel crushing plate is heated to 1 000 to 1 100 ℃ and then rapidly cooled in water. After water toughening treatment, a uniform metallographic structure can be obtained, and the metallographic structure can be fixed, avoiding the natural phase change in use and the deterioration of performance. Disadvantage of manganese steel is that it is more expensive, but from the overall consideration of service life and cost, ZGMn13 has a longer service life and lower cost than white cast iron.

    Jaw Plate Crusher Effect:

    Jaw plate is the main wear-resistant part of the jaw crusher: the movable jaw plate and the static jaw plate. According to the different types of the jaw crusher, there are various models and sizes. The jaw plate is made of new high manganese steel, super high manganese steel, Super high manganese steel and other materials are suitable for jaw crushers of various specifications.
    The jaw crusher is composed of a working cavity composed of movable and fixed jaws. Movable and fixed jaws bear huge crushing force and friction of materials, and are easily worn out. In order to protect the jaw plate, it is generally used in the movable and fixed jaws. A wear-resistant liner is installed on the surface, which is also called a crushing plate.

    Surface of the crushing plate is usually made into a tooth shape, and the angle of the tooth peak of the crushing plate is 90°～120°, and its size is determined by the nature and lumpness of the material to be crushed. When crushing large pieces of material, the angle should be larger; Angle can be smaller when it is a piece of material. The size of the tooth pitch depends on the particle size of the product, and is usually approximately equal to the width of the discharge port, the ratio of the tooth height to the tooth pitch can be taken as 1/2～1/3.

    Jaw Plate Crusher When working:

    wear speed of the upper and lower parts of the crushing plate is different, the lower part wears faster than the upper part. When the jaw crusher is working, the crushing plate directly contacts the material and bears the huge crushing force and friction of the material, the service life of the crushing plate is directly related to the work efficiency and production cost of the jaw crusher. Therefore, it is particularly important to extend the service life of the crushing plate of the jaw crusher. Strengthening the service life of the jaw crusher’s crushing plate can be considered from the aspects of design, material selection, assembly and improvement during use.

    Biggest consumption in the production of a crusher is the jaw, so the quality must be checked in the selection of talents. It can also be said that the quality of a crusher is actually based on the service life of the jaw. Shell is generally not easily damaged.
