Hey there! As a supplier of jaw plates, I’ve seen my fair share of installation issues over the years. In this blog, I’m gonna chat about the common installation errors that can pop up with jaw plates. Jaw Plates
1. Incorrect Alignment
One of the most frequent mistakes is incorrect alignment. When you’re installing jaw plates, getting them lined up properly is a big deal. If the movable jaw plate and the fixed jaw plate aren’t aligned right, it can cause a whole bunch of headaches.
First off, uneven wear is a major issue. When the plates aren’t aligned, the material being crushed won’t be evenly distributed across the surface of the plates. Some parts of the plate will take on more stress and wear out faster than others. This means you’ll have to replace the jaw plates way more often than you should, which can get expensive real quick.
Secondly, it can lead to reduced crushing efficiency. The crusher won’t be able to break down the material as effectively because the wrong parts of the jaw plates are doing most of the work. You might end up with larger pieces of material coming out of the crusher than you’d expect, and that’s not good if you’re looking for a specific size of crushed product.
To avoid this, make sure you use the right tools for alignment. Check the manufacturer’s guidelines for the correct alignment measurements. You can use a straightedge or a laser alignment tool to ensure that the movable and fixed jaw plates are parallel to each other and that they are centered within the crusher frame.
2. Improper Bolt Tightening
Bolt tightening is another area where things can go wrong. If the bolts that hold the jaw plates in place aren’t tightened correctly, it can spell disaster.
If the bolts are too loose, the jaw plates can shift during operation. This shifting can cause the same problems as misaligned plates, like uneven wear and reduced crushing efficiency. Plus, loose bolts can come completely out, which can be extremely dangerous. The jaw plates could potentially fall out while the crusher is running, and that’s a huge safety hazard.
On the other hand, if you overtighten the bolts, you can crack the jaw plates or damage the crusher frame. Each bolt has a specific torque value that it should be tightened to, and it’s important to follow these specifications.
To get the right bolt tightening, use a torque wrench. It’s a tool that allows you to tighten the bolts to the exact torque required. Don’t just rely on your gut feeling when tightening the bolts. Make sure you’re referring to the manufacturer’s torque chart for the correct values.
3. Dirty or Damaged Surfaces
Before you install the jaw plates, you need to make sure the surfaces where the plates will be mounted are clean and undamaged.
If there’s dirt, debris, or rust on the mounting surfaces, it can prevent the jaw plates from sitting flush against the crusher frame. This can lead to uneven pressure distribution and increase the risk of premature wear. The dirt can also act as an abrasive, causing even more damage to the plates and the frame over time.
Similarly, if the mounting surfaces are damaged, like having cracks or dents, it can affect the stability of the jaw plates. The plates may not be held securely in place, and they could shift during operation.
So, take the time to clean the mounting surfaces thoroughly. Use a wire brush to remove any loose dirt, rust, or debris. You can also use a degreaser to get rid of any oil or grease. If there are minor scratches or dents, you can try to smooth them out with a file or a grinder. But if the damage is severe, you might need to replace the affected parts of the crusher frame.
4. Wrong Type of Jaw Plates
Using the wrong type of jaw plates for your crusher is a major no – no. Different crushers have different requirements, and using incompatible jaw plates can lead to all sorts of problems.
For example, if you use jaw plates that are too thick or too thin for your crusher, it can affect the clearance between the movable and fixed jaw plates. This clearance is crucial for proper crushing operation. If the clearance is too small, the crusher might get jammed, and if it’s too large, the crushing efficiency will be poor.
Also, different jaw plate materials are designed for different types of crushing applications. If you’re crushing very hard rocks, you need jaw plates made of a high – strength alloy. Using a softer material for this type of job will result in rapid wear and tear.
When choosing jaw plates, carefully consider the specifications of your crusher and the type of material you’ll be crushing. Read the crusher’s manual and talk to the manufacturer if you’re unsure.
5. Not Checking for Interference
Sometimes, there can be interference between the jaw plates and other components of the crusher. This could be due to improper installation of other parts or a design issue.
For instance, if there are other parts of the crusher, like the toggle plate or the pitman, that are too close to the jaw plates, they can rub against the plates during operation. This rubbing can cause excessive wear on both the jaw plates and the interference – causing parts.
Before installing the jaw plates, check for any signs of potential interference. Look at the clearance between the jaw plates and all the other components in the crusher. Make sure there’s enough space for the jaw plates to move freely without hitting anything. If you find any issues, make the necessary adjustments to ensure proper operation.
6. Ignoring Installation Instructions
Last but not least, ignoring the installation instructions that come with the jaw plates is a huge mistake. The manufacturers spend a lot of time and effort developing these instructions to ensure the proper and safe installation of their products.
The instructions will tell you everything from how to prepare the crusher for installation to the correct sequence of bolts to tighten. They’ll also provide important safety information, like what protective gear to wear during installation.
So, don’t just toss the instructions aside. Take the time to read them carefully before you start the installation process. If you have any questions, don’t hesitate to contact the manufacturer or your supplier (that’s me!).
In conclusion, avoiding these installation errors is crucial for getting the most out of your jaw plates. By taking the time to do the installation right, you can extend the lifespan of the jaw plates, improve the efficiency of your crusher, and ensure a safer working environment.
