Emission Reduction Start From Bucket Teeth

Most people have not been know about bucket teeth. Because bucket teeth is a professional word to people. In fact, this product is an important part in excavator. Sometimes bad key part always lead to the failure. So we can not look down upon any details. Nowadays, more and more people pay attention to pollution. So people will always note reduction when making bucket teeth.

Our life become more and more better, but the environment we lived become more and more worse. Clear air has been more muddy. Using the excavator frequently is a most factor that casing environmental pollution. This is the industry recognized. In particular, the pollution caused by bucket teeth are mainly nitrogen oxides. How can we improve it effectively? Experts give advice that people could seize every possible detail. Bucket teeth is an important part. Certainly the most important is on the engine. Engine is key to the volume size. Generally speaking, the higher level will emissions less refer to the survey and the damage will be smaller. So reduction will improve the performance of the product.

In order to promote the formation of recycling economy further, many people in the industry have been launched a positive action. And they towards a higher step forward with unremitting efforts. Certainly talent resources that flow like water has become an important power.

Don’t Ignore Bucket Teeth Pins

Bucket tooth pin is a part that many machinery own. The machinery need to own this part to play a good work. While the bucket teeth pins have many different models. People can choose by different requirements. Choose the most suitable bucket teeth pin can make the bucket teeth work better. So you must select carefully. Different using environment should use different bucket teeth. Certainly the bucket teeth pins are also not same.
Bucket teeth pins are connecting parts. A lot of people do not pay enough attention to them. This is a wrong idea. The pins which with good quality can promote to develop the function of equipment. Some bucket teeth pins are horizontal type,but some vertical type. Generally speaking, structure with vertical type is relatively simple, and the horizontal type is more complex.
In terms of service life of bucket teeth pins, the pins are very durable. Because the bucket tooth pin is a part that used frequently. Exert function and adjusting direction are largely depends on the bucket tooth pin. As a connecting part, bucket teeth pins should bear a lot of pressure and friction. So it must be able to reduce the damage, repair and replacement times effectively. It is helpful to ensure all working successfully and improve working efficiency. The quality of bucket teeth pins have large effects on equipment.

Bucket Teeth Wear Resistant Shoes

Bucket teeth is the terminal of excavator working device. In the mining process the bucket teeth is driving friction repeatedly with the soil directly. It is belong to consumable parts. Especially in stone construction the bucket teeth is worn more quickly. It will cause a single bucket tooth fracture with uniform stress. Certainly the replacement cycle will be shorten and maintenance costs will be increase. In view of this situation, people has got a new technology, that welding the together two waste bucket tooth sleeve and forming a new bucket tooth.

Working contact area is enlarge after welding. The strength and wear resistance is greatly improved. While there is no new bucket teeth fracture because the contact surface is thin and long. It is more suitable for rock excavation and finishing work. At the same time, it is in good practical performance. You should normalized on casting to improve the organization, performance and extend its service life after casting. The service life of the bucket teeth has been improved more than two times in the same condition after reasonable heat treatment on casting.

Bucket teeth is strong wear after welding according to the mining operation in the use of stone. A new pair is equivalent to three previous pairs. The new one can improve the mechanical efficiency, saving considerable maintenance costs, but also reflect the working principle of repair the old and utilize the waste to maintenance management.

Process Of Bucket Teeth

There are three types of bucket teeth process. They are sand casting, forging casting and precision casting. Sand casting has lowest cost and the quality of the bucket teeth is worse than others. Forging casting although has high cost but the quality is best. Precision casting has very strict requirements to the raw material and technology level is relatively high. Due to mixed ingredients, some bucket teeth made by precision casting has high quality and abrasion resistance, even better than the bucket teeth which processed by forging casting.
Bucket teeth of excavator is an important part. And it is similar to people’s teeth. It is composed by the tooth and tooth tip which connect by pin shaft. You should only change the tooth tip because tooth wear failure is part of the tooth tip.
You should consider the work environment of the bucket teeth when you are using bucket teeth. Then decide which kind of bucket tooth model to choose. Generally speaking, using flat tooth when earth cutting, weathered sand and digging coal. Hard rock with excavation block using RC model. Block coal seam with block always adopt TL model. TL bucket teeth can improve the rate of lump coal.

Failure Analysis On The Bucket Teeth

The working face of the bucket tooth contact with the material to be excavated. In a complete mining process, different stages of their work has different force conditions. When the tooth tip contact with the material surface, the tooth tip is shocked strongly because of the quick speed. If the bucket tooth is low-intensity, it will be plastic deformation in the tip. With the increased digging depth, bucket teeth force will change. When bucket teeth is cutting materials , teeth and materials move relatively, it will produce large positive squeeze pressure. So it will produce larger friction between tooth face and materials. If the material is hard rock blocks or concrete, the friction will be large. The front face is significantly greater than the pressure on the after face. According to the front face is worn seriously, we can know the main external mechanical factors of tooth failure is positive pressure and friction, and it play an important role in the process of generating failure.
    We take two specimens from before and after working face and polish them, then take hardness test. We find there is large difference hardness on the same specimen, and preliminary judgment is inhomogeneous materials. After the specimen is ground, polished, corrosion, you will find obvious boundary on each specimen, only difference is the boundary position.
From the macro perspective,the surrounding is light gray but the central is dark. So it may be inlay casting. Look from the surface, the surrounding should  also be insert block. We found that the difference is obvious after taking hardness test on both sides of the border with HRS-150 digital Rockwell hardness tester and MHV-2000digital micro hardness tester. Through above analysis, it indicates that bucket teeth are inlaid caking. The closed portion is insert and the surrounding is matrix. Both ingredients are closed. Mechanical properties of  metallic materials depend on the material composition and heat treatment process. The composition is similar and the hardness is different, so the bucket teeth put into use without heat treatment. Observation of tissue is also proved this point.
