Reduce Tooth Breakage Rate

Bucket teeth of some excavators will be broken after working for a period of time while the excavators are mining and dumping. These phenomenons will not only effect the production task, but also increase production costs.

The main reasons to cause bucket teeth broken are that bucket tooth do not match, ore block is too large or the operational guidance is not perfect. Durable bucket teeth have wear resistance, they are very suitable for loading hard stones. The work place of self sharpening bucket teeth need inserted into the soil. For example, digging or loading sand need to use this one.

In order to reduce tooth breakage rate, we suggest operators use matching bucket teeth. Reducing the fragmentation of ore. Technical staff should try to reduce the fragmentation of ore, so that we can achieve the desired effect. Besides every operator had better own a complete operation manual. Some company even organize all operators learning and examination. And it also needs to be inspect in the following scene. After you have done the works above all carefully, the tooth breakage rate would be reduced.

Molding Process For Bucket Teeth

Now bucket teeth are made by sand casting, investment casting and squeeze casting. Different castings have different characteristic.

Molding material for sand casting is cheap and easy to get. The mold manufacturing is also easy. But there is always some defaults on bucket teeth surface. Such as sticky sand, sand inclusion, shrinkage hole, shrinkage porosity and so on.

Investment casting has high size precision, rough surface and small machining allowance. But it needs to set high riser for feeding. So that process yield rate will be decreased.

It is applying pressure to metal liquid continuous in the squeeze casting process. It can make the metal liquid solidified quickly. The grain refinement is better. Bucket teeth product has higher compactness because it solidification under pressure. Without using sand mold and sand core can prevent causing casting defaults at the same time, the product quality will be good, the process yield and production efficiency will be higher. While as a new kind of material forming technology, squeeze casting is usually in simple process, high material utilization rate, small machining allowance. Squeeze casting can save energy and without any waste discharge.
