Mechanical issues will arise when liner are used for longer periods than the time they are intended to last. The crusher won't allow users to press the liner too hard. A cracked or thin mantle may cause significant damage to the seat's surface.
There is no way of knowing when the liners have been worn down. However, there are two signs it is the right time to replace them
If you observe an increase of 10% or more drop in production level or throughput, it is a good indication the Cone Crusher Liners needs to be changed. Whenever you would like a useful source on shredder parts, look at this site.
It is recommended to change the liner in case it is not evenly worn across the chamber. It should be about 1" (2.5cm) thick at its lowest point. At about 3/4" to 5/8" (1.9 cm to 1.6 centimeters) thick the liner is likely to break, causing the backing material to start to fall apart. The liners will then fall off. If the liners are loose, continued operation could destroy the seat in the support bowl or on the head of the Cone jaw crusher.
A few cone crushers have an automatic liner replacement reminder. If new concave and mantle liners are installed the automatic reminder will be reset. While the crusher is running, the system tracks production capacities and calculates the liner wear rate. When the cone's liners are at the point of maximum wear, the system sends a flashing reminder to "Change Cone" on the cone setting meter. Reset the reminder system to keep the cone crushing efficient and reliable after the wear parts have been changed.
Important note: Never place the concave lining of the crusher with an old mantle or a brand new liner inside the crusher with an old liner. The profile of the crushing chamber could be altered by the blending of worn and brand new components. This will result in a decrease in the amount and quality of tons per hour produced.
Increase the life of liner components by ensuring proper distribution of feed
To get the maximum wear-life from your Mill Liners Foundry, and to ensure maximum crusher performance, it's essential to feed the crusher in a proper manner.
Feeding methods that are not correct
A segregated feed distribution which sends heavy material on one end of the crusher, and small material to the other side, will lead to inadequate wear on the liner. This can also lead to bounce in the ring if the pressure in the chamber is greater than that holding it down.
A feed that is not centered, or one that sends a majority of the feed to just one side of the crusher, will cause low liner wear as well as ring bounce and poor particle form. When you don't use the entirety of the chamber, you're not optimizing the performance of your crusher.
Proper feeding technique
The best way to ensure the longest life of your liner is to feed it with a choke Cone Crusher. Choke feeding allows a full chamber with material over it to help force the material in the chamber. Choke feeding reduces air pockets in the crushing chamber. This helps to create smooth, elongated particles.
