Mechanical problems will occur when the liners are utilized for longer than their intended life. A liner that is pushed too long will flex and break, and the stretching of a thin or damaged mantle can result in serious damage to the surface of the crusher.
There is no sure way to tell whether the liners are wear out, here are two indications that it's time to replace the liners:
Manufacturing level
If you notice a drop of 10% in production or throughput it's a sign that the Cone Mill Liners Foundry, needs to be replaced. Once you like to discover fruitful information on crusher liners, you have to browse around Crusherparts website.
Liner thickness
If the liner is wearing uniformly throughout the chamber, you should consider changing it when it has worn down to around 1" (2.5 cm) thick at the bottom. When it is about 3/4" to 5/8" (1.9 cm to 1.6 cm) thick, the liner will begin to crack, which will cause the backing material to begin to fall apart. The liners then fall off. This could cause the Cone Crusher's head and support bowl may be damaged if the liners fall off.
A few cone crushers have an automatic liner replacement reminder. When new concave and mantle liners are installed the reminder system automatically reset. The crusher's capacity for production is tracked by the system that determines the rate of wear. The system flashes a reminder on the cone setting meters to change cones when cone liners have reached their wear limit. When the wear components have been changes, reset the automatic reminder system to continue effective and reliable crushing.
A crucial point to remember Do not install a new cone liner in a crusher with an old mantle, or put a new mantle into the crusher that has a worn concave liner. Combining worn and new components alters the shape of the crushing chamber. It will also hinder the flow of feed into the chamber for crushing, which will reduce the tons per hour of production.
Improve liner life with correct distribution of feed
To get the longest wear-life from your Crusher Liners as well as ensure optimal crusher performance, it's important to feed your crusher correctly.
Feeding methods that are not correct
A segregated feed distribution, one that delivers large materials to one side of the crusher and small material to the other side, could result in poor liner wear. It will also cause bounce in the ring if the chamber pressure is higher than the pressure that is holding it down.
A feed that isn't centered, or one that only delivers a portion of the feed to a single crusher side, can also result in poor liner wear and ring bounce that is not as good, and a poor shape of the particle. The crusher isn't performing at its best performance if you don't utilize the entire chamber.
Proper feeding technique
The best way to guarantee optimum liner life is to feed it with a choke Cone Crusher. Choke feeding creates a complete chamber that has material over it to help get the material within the chamber. Choke feeding reduces air pockets in the crushing chamber to limit the creation of flat, elongated particles.
