Hey there! As a supplier of Excavator Hydraulic Crushers, I've seen my fair share of wear and tear on the crushing teeth of these awesome machines. In this blog, I'll explain how this wear and tear occurs and what you can do about it.
First off, let's talk about what an Excavator Hydraulic Crusher is. It's an attachment for excavators that's used to break down materials like concrete, rocks, and asphalt. The crushing teeth are the key components that make this happen. They're the ones that come into direct contact with the material being crushed, so they take a beating.
One of the main causes of wear and tear on crushing teeth is the nature of the material being crushed. Different materials have different hardness levels. For example, concrete can vary in hardness depending on its composition and age. If you're crushing harder materials like granite, the teeth will experience more stress and abrasion compared to when you're dealing with softer materials like lightweight concrete.
The hardness of the material causes abrasion. Abrasion is like sandpaper rubbing against the teeth. As the teeth crush the material, tiny particles of the material grind against the surface of the teeth. Over time, this constant grinding wears away the outer layer of the teeth. The sharp edges of the teeth start to dull, which reduces their efficiency in crushing the material. You might notice that the crusher takes longer to break down the same amount of material as time goes on, and that's because the teeth aren't as sharp as they used to be.
Another factor that contributes to wear and tear is the cutting force. The hydraulic system in the Excavator Hydraulic Crusher generates a powerful cutting force to break the material. When the teeth make contact with the material, this force is transferred to them. If the cutting force is too high for the teeth to handle, it can lead to chipping and fracturing. For example, if the operator tries to crush a large chunk of material that's too hard for the crusher, the excessive force can cause parts of the teeth to break off.
Impact loading is also a big culprit. When the crusher bites into the material, there's a sudden impact. This impact can cause micro - cracks in the teeth. These micro - cracks might not seem like a big deal at first, but over time, with repeated impacts, they can grow larger and eventually lead to the complete failure of the teeth. Imagine hitting a glass with a hammer gently at first. There might be a small crack that you don't even notice at first, but with more hits, the crack spreads and the glass shatters. It's similar with the crushing teeth.
The operating environment can play a role as well. If the crusher is used in a dusty environment, the dust particles can get into the moving parts and also contribute to the abrasion of the teeth. In a wet environment, especially if the water is contaminated, it can cause corrosion of the teeth. Corrosion weakens the structure of the teeth, making them more prone to wear and breakage.
Now, for some types of crushers like Rotary Pulverizer / Concrete Crushers, the wear pattern can be a bit different. Rotary pulverizers have rotating crushing teeth, which means they experience a different kind of stress. The rotation can cause uneven wear on the teeth. The parts of the teeth that come into contact with the material first might wear out faster than the rest of the teeth.
So, what can you do to minimize the wear and tear of the crushing teeth? Regular inspection is crucial. You should check the teeth before and after each use. Look for signs of wear like dullness, chipping, or cracks. If you notice any problems early, you can take action to prevent further damage.
Proper maintenance is also essential. Keep the crushing teeth clean. Remove any debris or dust that might be stuck to them after use. Lubricate the moving parts according to the manufacturer's instructions. This can reduce friction and wear.
Another important thing is to operate the crusher correctly. Train your operators to use the appropriate cutting force for the material being crushed. Avoid overloading the crusher by trying to break down materials that are too large or too hard for it.
If you do find that the crushing teeth are worn out beyond repair, it's time to replace them.
