The material and function of the wedge of the jaw crusher

September 23, 2024

The wedge of the jaw crusher (sometimes also called wedge iron or adjustment device) plays an important role in the crusher. It is mainly used to adjust the size of the discharge port, thereby controlling the discharge particle size of the material and improving the crushing efficiency. Regarding its material and function, it can be elaborated in detail as follows:

Material

The wedge material of the jaw crusher is diverse, but the main factors to be considered are its wear resistance, impact resistance and cost. Common materials include:

‌High manganese steel‌: High manganese steel is widely used due to its high wear resistance and impact resistance. It can withstand the extrusion and impact force of the stone and has a certain wear resistance. However, the hardness of high manganese steel is too high, which may sometimes lead to easy breakage.

‌Alloy steel‌: Alloy steel has the characteristics of high strength, high hardness and high wear resistance, and is particularly suitable for crushing materials with higher hardness. But its cost is relatively high.

‌Other materials‌: Such as high chromium cast steel, copper alloy, titanium alloy, etc., these materials have a narrow range of application, are expensive, and are generally not commonly used.

Function

The main functions of the wedge of the jaw crusher are as follows:

‌Adjust the width of the discharge port‌: By moving the front and rear wedges and changing the distance between them, the size of the discharge port can be adjusted. This adjustment method is simple and fast, which can save time and reduce downtime.

‌Control the particle size of the material‌: By adjusting the size of the discharge port, the particle size of the material can be effectively controlled to meet different production needs.

‌Improve crushing efficiency‌: Suitable wedge material and reasonable adjustment method can give full play to the crushing capacity of the jaw crusher and improve crushing efficiency.

In summary, the wedge material of the jaw crusher is diverse, and the workload of the crusher, the hardness of the stone and other factors need to be considered when selecting. Its role is mainly reflected in adjusting the size of the discharge port, controlling the particle size of the material and improving the crushing efficiency. In practical applications, the appropriate wedge material and adjustment method should be selected according to specific needs.
