Cone crushers are not a new one for the machinery industry, because it was developed more than a century ago to give tertiary, secondary and also quaternary material reduction. Just similar to some other compression crushers, these cone crushers also feature the crushing cavity or chamber where the rock is crushed to the minimum size. This specific crushing chamber in the cone crusher is actually the space made between the concaves and mantle. Both these items are perfectly protected from the regular wear by the manganese liners which are replaceable.

Selecting the best cone crusher liner:

Currently, there are more varieties of liners available to hold fine and coarse feeds, but your selection of liner depends on the different factors. The most significant factor in the selection of this cone crusher liner is the feed. You must contain the top graded feed going into the existing crushing chamber. This top graded feed is commonly considered as,

0 to 10 % passing the closed side setting.

40 to 60 % passing the midpoint.

90 to 100 % passing the closed side feed opening. Some of the individuals look at about 80 percent of the open side also and choose the smaller of the two.

The users have to match the full grade of the feed not just its size so that you use the entire chamber. It is crucial to use as much of the crushing chamber as possible to attain the desired throughout and necessary amount of reduction. Most of the wear on the crusher liners takes place before the parallel zone but this wear might be highlights if the feed is very small. At the same time, you will end up with the pocket before this particular parallel zone way too quickly. Additionally, if the size of the feed is too coarse, then the material of the feed will keep penetrating around its opening and it will cause the top of the liners to get away quickly. Due to this feed opening is passed over, throughput is reduced whereas there is a decreased production. The output shade will be coarser and the product would be slanting not cubical. When you consider the volume limit, it will be exceeded at the least power draw.

How important is the liner selection?

While running the cone crusher, the selection of the liner is the most important thing for its proper and regular functions. The best cone crusher liner selection is crucial to keep your cone crusher equipment running powerfully and making the reliable sellable product. A right liner product will give more amounts of benefits to the overall operation of your cone crusher. While choosing the cone crusher liner, it is significant to notice that it should have the best discharge setting to match your required closed side settings in the products you make. When you do it, you can able to obtain the more even wear the whole time of the liner life. By choosing the right liner, your amplifier draw will be highly consistent and decrease the chance of upper frame bounce that may cause an excess condition for your cone crusher.

Once you have learnt how to choose the liner for your cone crusher, it is also very important to learn when to chance such liners. Generally, the liners which exceed their planned operating life may cause some mechanical problems with your cone crusher equipment. The liner which is pushed for the longer period of time will crack and flex. This bending of such cracked or thin mantle will cause some of the severe seat surface damage. You may notice two indications when there is a time to change the cone crusher liner including,

Production level

When you notice the 10 % or more drop in your level of production, it will be the best indication to change the liners of the cone crusher.

Liner thickness

If the liner is evenly wearing in the entire portion of the chamber, you have to consider changing it when its size is getting down about 1 inch or 2.5 cm thick at the bottom. Some cone crusher machines have a feature of automatic liner change reminder. For avoiding inconveniences, you can install the automatic reminder in your existing cone crusher for ease.
