Echo board selection material selection can consider the following factors
Feb 04, 2019

The jaw plate is subjected to severe plastic deformation wear and cutting wear during use. The material used in the jaw crusher jaw plate is required to have high hardness to resist plastic fatigue and cutting wear, and has certain toughness to prevent brittle flaking or fracture. Therefore, the following factors should be fully considered when selecting the jawboard material of the jaw crusher:

(1) The larger the size of the jaw crusher, the larger the blockiness of the broken material and the greater the impact load on the jaw. At this time, when selecting the material, first consider the hardness to ensure the toughness of the jaw.

(2) Breaking different materials (such as granite, quartzite and limestone), the material of the jaw plate should be different: the higher the hardness of the material, the higher the hardness of the corresponding jaw.

(3) The force mode and wear mechanism of the movable jaw and the fixed jaw are different. The movable jaw is subjected to a large impact force. Therefore, the toughness should be considered first, and the fixed jaw is supported by the frame, so the hardness can be prioritized.

(4) When selecting the material of the E-plate, we should also consider the technical and economic effects, and strive to achieve high quality and low price, and have market competitiveness. At the same time, it should also consider the rationality of the process, so that manufacturers can easily organize production and control quality.

In combination with the above problems, the High Hardness Steel Plate fully meets the requirements, so it is more suitable than ordinary steel plates.
