When To Change Cone Crusher Liners

Mill Liners Foundry

Mechanical issues will arise when liners are used for longer that their intended use. When a liner is pulled to far will stretch and crack, and the stretching of a thin or damaged mantle can result in serious damage to the surface of the crusher.

There's no way to tell when the liners are worn out. However, these are two indicators that it's the right time to replace them

Production degree

If you see a drop of 10 percent or more in throughput or production, it's a sign that your Cone Shredder Parts must be replaced. In case where you want a useful source on crusher liners, browse around this website.

Liner thickness

You should change the liner if it is not evenly worn across the chamber. It should be approximately 1" (2.5cm) thick at its lowest point. The backing material begins to break between 3/4" to 5/8". The liners will eventually fall off. If the liners are loose the continued operation may destroy the seat in the support bowl or on the head of the Cone jaw crusher.

A few cone crushers feature an automatic reminder for replacement of the liner. When new concave and mantle liners are installed the automatic reminder will be reset. As the crusher operates it tracks the production capacity and calculates wear rate of the cone. The system flashes a message on the cone setting meters to change cones when cone liners have reached their wear limit. After the wear parts are changed, you can reset the automatic reminder system to ensure continued efficient and efficient crushing.

Important note: Do not put an elongated lining inside an existing crusher with an old mantle or a brand new liner inside the crusher with an old liner. Mating new and worn components will change the profile of the crushing chamber. This will restrict the feed from entering the crushing chamber. This will reduce the tons per hour of production.

Improve liner life with correct feed distribution

To get the maximum wear-life out of your Mill Liners Foundry and to ensure maximum crusher performance, it is necessary to feed the crusher properly.

Methods of feeding that are incorrect

Wear and tear on the liner is often caused by the segregated distribution of feed which sends heavy materials to one side and smaller material to the opposite side. Additionally, it can cause ring bounce when pressure in the chamber is greater than the pressure that holds it down, and also larger products and poor particle form.

A feed that is not centered, or one that only sends a small portion of the feed to a single crusher side, could result in poor liner wear poor ring bounce and even poor particle shape. When you don't use the entire chamber, you are not maximizing crusher performance.

Correct feeding method

Choke feeding your Cone Crusher is the ideal way to prolong its life. Choke feeding creates a complete chamber with material over it to help force the material in the chamber. Choke feeding eliminates air pockets inside the crushing chamber, which helps to create long, flat particles.
