Cone crusher as a commonly used crushing equipment, its broken product grain size is the main indicator of the quality of consumption. In particular, some applications, the requirements of cone crusher products need to fit a certain type of grain, so broken product grain control is necessary.

 

Cone crusher

 

Cone crusher machine is widely used in metallurgy, mining, water conservancy and construction and other areas, and in the corresponding consumption process has played a key role. The main object of the crushing machinery is ore material, its grain shape (geometric shape of the material particles) is the main indicator of the quality of the broken yield, usually can be divided into cubic and needle-like.

 

The mass fraction of the needle-like particles in the crushed product is the needle rate, which is the quantitative index to evaluate the grain size of the crushed product. The main factors affecting the rate of the needle include the type of ore, the type of crusher, the crushing stage, the feed size, the size of the closed edge, the amount of material fed and the eccentric shaft speed.

 

In the area of ​​construction, the increase in needle-like particles in the concrete aggregate will result in a rise in the overall compressive strength of the building and an increase in the cement consumption during the construction process. Similarly, the increase in needle-like particles in the asphalt mixture Resulting in a mixture of bulk density and compressive strength and tensile strength. It can be seen that the needle rate has an important effect on the amount of broken product.
