A crusher in the Philippines is considered as the unsung hero among equipment. Although it’s not as popular as excavators, forklifts, or loaders, it’s an extremely useful and versatile machine. Crushers can break down materials such as rocks, stones, and ore and reduce their size. Because of this, it’s a necessity in several industries — including quarrying, recycling, mining, and demolition. But this equipment can get blocked occasionally, which can affect your site’s productivity. To help you, here are some tips on preventing and fixing blocked crushers. Read on!

 

Avoiding Overfeeding the Crusher

Overfeeding is not the right solution when you’re trying to process more materials in one day. Instead of greater production, you’ll only end up with reduced efficiency. Adding more material will only end up stalling the crusher.

The manufacturer of your crusher will include a manual on how to operate it properly. This includes the proper feeding method to prevent blockages. You need to set up the right feeder speed and adjust the other settings or you’ll end up with an overloaded situation and a blocked crusher.

 

Prevent Entry of Other Materials

Prevent Entry of Other Materials

Stalling and bridging can happen when a foreign material enters the crusher. This might be excessive clay or wood. Metal parts such as bucket teeth and dumper wear plates might also break off and enter the crusher, therefore causing a blockage. These can damage not just your crushers, but also your conveyors and other process equipment.

To prevent tramp metal from entering your crusher, you can consider using a tramp metal detector to protect your investment. Another good practice is to regularly inspect the metal parts to spot early signs of damage and prevent them from breaking off.

Other than this, be alert for excessive clay which can prevent your materials from passing through the crusher as this can also lead to stalling.

 

Reduce Entry of Oversized Material

Crushers are made to reduce the size of materials — whether it’s a rock, stone, or ore. But blockages can occur especially if you feed your equipment with oversized material. Ensure that the size of the raw material is matched to the opening of the crusher to prevent this incident.

If you need to process an oversized material, consider using other tools and equipment to reduce its size first. One popular option is a hydraulic breaker, which is a mechanical device that can demolish stone, concrete, asphalt, and other materials. A pulverizer is a great option too.

 

Regularly Inspect and Maintain the Crusher

Daily visual inspections not only help keep your crusher in peak condition, but they can also help you prevent blockages. Setting aside time each day to look for material build-up and blockage can significantly improve your uptime and prolong the components of your crusher.

This is especially important when you’re processing wet and sticky material which can easily cause clogging. In this case, you might need to perform visual inspections more than once a day. Make sure that you’re trained to perform an inspection and always consult the manufacturer’s manual for your safety before doing this.

 

Blockages Should Only Be Cleared by Professionals

When you encounter a blockage, you might be at a loss at what to do. There are a few tools you might need, but only trained and competent persons can do the clearing. This is important especially if manual removal is needed. In this case, make sure that the crusher and the associated plant are stopped and isolated.

When you attempt a clearing, there are risks involved. Some examples are being struck by material, slipping, sudden movement from the crusher components, and more. Stalled crushers can cause fatal accidents because of material being ejected, so don’t attempt to do the clearing if you’re not suitably trained. Don’t hesitate to call for help if the situation calls for it.

 

Use A Hydraulic Breaker to Clear Blockages

Now that you understand that calling trained professionals is recommended for clearings, the next step is to know what tool to use. For bridged crushers, the popular option is to use a hydraulic breaker fitted to a breaker boom, which is operated remotely. This way, the equipment could be operated from a safe position using CCTV.

There are some cases that operators choose to fix the problem by barring the blockage while the crusher is still running. This practice is dangerous and can lead to accidents.

 

Key Takeaway

To reduce the occurrence of blockage, be mindful of how you operate your crusher. Prevent this incident by feeding the equipment according to its capacity. Be aware of foreign objects that can enter your crusher as they can cause degradation of the components aside from the blockage. Finally, call competent and trained persons to perform the clearing because it’s a dangerous activity.
