Improving The Design In Bucket Teeth Center

In the analysis of total service life of bucket teeth, we must design the center position of bucket teeth by wear rule to solve the problem of large resistance in the early using stage. So bucket teeth center must be higher than installing center in designing. If the bucket teeth has been moved high, the slope on the bucket teeth will become smaller. At this time, its wear should be decreased and it is easy to shovel the ore.

Don’t move the center up too much. Because mostly moving up will make the service life of the bucket teeth decrease. But move the center up about 40mm will be better.

There are separate gas hole, blowhole and reaction blowhole in the kneading castings. In the constitute process of shrinkage hole and shrinkage porosity, mostly accompanied by gas separation. If it has too high gas content or too much gas all will increase the shrinkage or porosity composition. We can easily see that the stomatal distribution is random and often with large hole. They are mostly spherical and balls. So we can determine that porosity is belongs to the blowhole.
