Hey there! As a supplier of European Jaw Crushers, I've seen firsthand how important it is to operate the adjusting device correctly. This not only ensures the crusher works at its best but also extends its lifespan. In this blog, I'll share some tips on how to do just that.
Understanding the Adjusting Device
First off, let's talk about what the adjusting device on a European Jaw Crusher does. It's a crucial part that helps you control the size of the output material. By adjusting it, you can make the crushed material finer or coarser according to your needs.
There are a few types of adjusting devices commonly used in European Jaw Crushers. One is the wedge adjusting device. It's relatively simple and easy to operate. You just need to move the wedge block to change the discharge opening size. Another type is the gasket adjusting device. This involves adding or removing gaskets to adjust the distance between the fixed jaw and the movable jaw, which in turn affects the output size.
Pre - operation Checks
Before you start adjusting the device, you've got to do some pre - operation checks. First, make sure the crusher is turned off and disconnected from the power source. Safety first, right? Then, visually inspect the adjusting device for any signs of damage, like cracks or excessive wear. Check the bolts and nuts to ensure they're tight. Loose fasteners can cause problems during operation.
Also, take a look at the lubrication. The adjusting device needs proper lubrication to work smoothly. If the lubricant is dirty or low, replace or refill it as needed.
Operating the Wedge Adjusting Device
If your European Jaw Crusher is equipped with a wedge adjusting device, here's how you operate it.
First, locate the adjusting bolts. These are usually on the side of the crusher. Use the appropriate tools, like a wrench, to loosen the locking bolts. Once they're loose, you can start adjusting the wedge block.
To increase the discharge opening size, turn the adjusting bolts in the direction that moves the wedge block backwards. This will create more space between the jaws, allowing larger materials to pass through. Conversely, if you want a finer output, turn the bolts the other way to move the wedge block forward, reducing the gap.
After you've made the adjustment, make sure to tighten the locking bolts securely. This prevents the wedge block from moving during operation.
Operating the Gasket Adjusting Device
For crushers with a gasket adjusting device, the process is a bit different.
First, you need to remove the side cover of the crusher. This gives you access to the gaskets. Carefully count the number of gaskets currently in place. To increase the discharge opening, you can add more gaskets. Make sure the gaskets are evenly placed and of the right thickness.
If you want a smaller output size, remove some gaskets. But be careful not to remove too many at once. After adding or removing the gaskets, put the side cover back on and tighten the bolts.
Testing the Adjustment
Once you've adjusted the device, it's time to test it. Reconnect the power source and start the crusher. Feed a small amount of material into it and observe the output. Check if the size of the crushed material matches your requirements.
If it doesn't, you may need to make further adjustments. Don't be afraid to make small changes and test again until you get the desired output.
Maintenance of the Adjusting Device
Proper maintenance of the adjusting device is essential for its long - term performance. Regularly clean the device to remove any dust, dirt, or debris. This helps prevent abrasion and damage.
Inspect the device frequently for wear and tear. Replace any worn - out parts promptly. Also, keep the lubrication up to date. Use the recommended lubricants and follow the manufacturer's guidelines for lubrication intervals.
