How To Change Cone Crusher Liners
Liners that are longer than their operating lifespan could cause mechanical problems for the crusher. If a liner is pushed too long will flex and crack, and the flexing of a thin or cracked mantle will cause severe seat surface damage.
There is no sure method to determine when the liners are damaged Here are two signs it is time to change the liners:
Production degree
When you see a 10% or more drop in production level or throughput, it's an excellent indication that the Cone Crusher Liners need to be changed. Whenever you aim for an article source on crusher liners, check this site out.
Liner thickness
If the liner is worn evenly throughout the chamber you should consider changing it once it's worn down to around 1" (2.5 cm) thick at the bottom. The backing material will begin to break around 3/8" to 5/8". The liners will eventually fall off. This could cause the Cone Crusher's head and support bowl may be damaged in the event that the liners break off.
A few cone crushers feature an automatic reminder for replacement of the liner. If new concave and mantle lines are put in place the reminder system automatically reset. The crusher's capacity to produce is monitored by the system, which calculates the wear rate. The system displays a warning on the cone setting meters to change cones when the cone liners have reached their maximum wear point. Set the reminder system to keep the cone crushing efficient and reliable after the wear components have been replaced.
Important note: Do not place the concave lining of a crusher that has an old mantle or a brand new liner into an existing crusher that has an old liner. The shape of the crusher's chamber will be altered due to the blending of worn and brand new components. This will result in a reduction in the number and quality of tons produced per hour.
Enhance the lifespan of your liner by using the correct distribution of feed
To get the most wear life out of your Mill Liners Foundry in addition to ensuring optimal crusher performance, it is necessary to feed the crusher properly.
Methods of feeding that are incorrect
Poor liner wear can be caused by the segregated distribution of feed that sends large materials to one side , and smaller materials to the other side. Moreover, it will result in ring bounce when the pressure inside the chamber is greater than the pressure holding it down, in addition to more oversized products and poor particle form.
A feed that is not centered, or one which sends the majority of the feed to one end of the crusher, can result in an uneven wear of the liner rings bounce, poor particle form. The crusher isn't performing at its best performance if you don't utilize the entire chamber.
Correct feeding method
Choke feeding your Cone Crusher is the best way to prolong its life. Choke feeding lets you get a fully-filled chamber with materials. This will help push the material through the chamber. Choke feeding eliminates air pockets within the crushing chamber, which helps to create long, flat particles.
