1. Manufacturing
The construction and material of an excavator's bucket teeth and adapters is a major criterion, as this will directly determine its wear life and strength, but so is the shape and design.
Excavator Bucket teeth are cast in a foundry. The material used in the casting process and the type of mold used will determine the lifespan, breakage and assembly time of the bucket teeth. In addition, the heat treatment process affects hardness, which in turn affects wear life.
2. Wear life
The wear life of excavator bucket teeth is affected differently by various materials. Sand is extremely abrasive, and rocks, mud, and other materials that are excavated or loaded can affect their wear life, depending on their quartz content. The larger the wear surface, the longer the life of the teeth before replacement.
These excavator bucket teeth are best suited for loading and material handling applications rather than digging or trenching, which require high penetration and impact. Larger wear surface areas tend to be less efficient when penetrating hard, compacted ground.
3. Penetration
The amount of surface area in contact with the ground during penetration determines the efficiency of the tooth. If the teeth have a larger width, blunt or "spherical" surface area, additional power from the excavator is required to penetrate the material, so more fuel is used and more stress is created on all parts of the machine .
The ideal design is for teeth to self-sharpen, which means they continue to self-sharpen as they wear.
To penetrate tightly compacted rock or frozen ground, you may need sharp "V" shaped teeth called "double tiger teeth". These are ideal for digging and trenching as they allow the bucket to traverse the material with ease, but since there is less material in them, they have a short lifespan and they do not provide a smooth bottom for holes or trenches .
4. Influence
Teeth with high impact resistance withstand penetrating impacts and high destructive forces. They are best suited for excavation and trenching applications when using excavators, backhoes or other machines with high digging forces, especially in rocky environments or quarries.
The fit of the teeth to the adapter is very important, as incorrect fit can re-apply stress to the pin, which can create weak points, or the pin can even come off under stress.
