BTMA-FAQ about the Cone Crusher

What can a cone crusher crush?

Cone crushers can crush a variety of mid-hard, above mid-hard rocks and ores. Such as granite, basalt, quartz, limestone, etc. The cone stone crusher machine is often used for secondary, tertiary fine crushing.

The jaw or impact crushers which crush the large materials. The series of crushers are widely used in quarry, mining, concrete crushing, construction waste recycling.

How long to replace cone liner?

The liner as the easily damaged parts of the cone crusher, if it was evenly worn down to about 2.5cm, we should consider replacing it. Because the liner made of manganeses will crack when it about 1.6-1.9cm thick. Then causing the lining plate to begin to disintegrate. Further led to the liners fracture. If we don’t solve the problem and the machine continues working, it will destroy the seat or head.

How to choose a right cone liner?

When we select the cone crusher liner, we can consider three factors of the output, power consumption and the liner wear resistance. According to the size of the feed, the change of the size, the distribution of the feed size, the hardness and wear resistance of the material to choose the liner. Therefore, we need to know the points as follow:


The longer the liner, the higher the power consumption.

Choose a short liner for hard materials, choose a long liner for soft materials.

Choose a short liner for fine material and long liner for coarse materials.

In general, the materials that smaller than the closed edge discharge opening can not exceed 10% . If it exceeds 10% , the power consumption increases and the product granularity becomes flaky. The moisture content of viscous materials will affect the throughput of the material. So the moisture of the material is generally not more than 5 %.


How to get the better-finished particle shape

All the feeding conditions, crushing cavity type, and the crushing ratio will affect to get better-finished particle shape. In order to get a good production particle shape, we have to feed it correctly. The correct method of feeding is a full cavity, stable continuous feeding. Therefore, it is necessary to equip the cone crusher with a hopper or vibrating feeder. If not, it is almost impossible to feed continuously which also can’t get a better particle size.


How to improve the cone crusher efficiency closely consider the two parameters of efficiency and capacity. Improve efficiency, the capacity will reduce. Increase the capacity, the efficiency will reduce. But if you want to improve the efficiency, it must ensure the crushing head and drive system properly smooth working.


What cone crusher speed is right for me

The different speed of cone crusher applies to the different crushing application. Below are suggested guidelines:


Low speed which applies for secondary crushing, the jaw crusher for primary crushing.

Medium speed which applies for coarse feed such as gravel crushing

Standard speed which applies for tertiary crushing

High speed which applies for sand plant
