Crawler crusher plants are usually reliable, efficient, and capable of high volumes. A crawler mobile crusher is a good choice for larger quarries or those who work short-term contracts and want to reduce the hassle of transporting their machinery. Using a crawler chassis increases mobility, saves you time, and can even help protect the machine since you don’t have to worry about the risks of damage from repeated loading and unloading.
Choosing a Crawler Mobile Crusher
Crawler mobile crushers are available in a variety of types, including jaw crushers and impact crushers. The jaw crusher style is one of the most popular, as these crushers are usually the first step in processing any rock or building materials. The crusher can be positioned at the face of the quarry or moved on-site to wherever the materials must be processed. Depending on the layout of the site and the intended use of the crusher, it can be connected to a conveyor belt to make processing the output materials easier.
Upgrading a Crusher to a Crawler
If you already own a jaw crusher, but it’s static, it may be possible to upgrade it by attaching it to a crawler chassis. Not all crushing machinery manufacturers support this so it’s a good idea to seek advice before attempting such a job. These devices are large and create a lot of vibration when in operation, so it’s essential any chassis connection is performed properly and is strong.
What to Look for in Your Next Crusher
The type and size of your mobile crawler crusher are the main things you should consider when you’re narrowing down your shopping list, but there are some other important issues too. For example, on a busy site where you’re processing hard materials, the discharge chute will be under a lot of strain during the crawler mobile crusher‘s operation. The chute will require regular maintenance and is one of the most common points of failure on mobile crushers.
You can reduce the damage the chute takes by adding a discharge rock box with a wear bar that allows a buffer of material to build up, reducing the wear the box takes. These are often marketed as ‘zero maintenance’ solutions and they do certainly reduce the wear on the chute dramatically.
The other parts of the crusher will still need to be serviced and calibrated, but it’s relatively rare for hoppers to fail, and jaw crushers are quite simple devices so the care and maintenance required for those are minimal too. As long as the mobile screening plant can accept a high enough volume of rock, and is outputting at a rate sufficient to feed your secondary feeder, you should find a crawler jaw crusher that will be a reliable addition to your site.
If you’re processing very hard materials, or you need particularly high volume, talk to the retailer to ensure the crusher you’re considering will be up to the job. These are highly specialist machines and the retailer will be able to advise on which option is best suited for your application.
