How to control the content of the needle-shaped discharge of the cone crusher

Cone breaking is a common equipment for the preparation of sand and gravel aggregates for highway construction. This is because the needle-like content of the finished sand and gravel material meets the highway construction standards. Then, how does the cone breaking achieve reasonable control of the needle-like content of sand and gravel?

First of all, when the cone is broken, the material is broken in the crushing chamber, and the needle-like content increases rapidly. As the crushing event increases, the needle-like content increases gradually, but when the crushing event is further increased, The material, including the needle-like particles, is subjected to multiple extrusions, at which point the needle-like content begins to decrease.

Therefore, the frequency of the crushing event in the operation of the cone crusher is larger, and the content of the needle-shaped sheet is less. Then, we can increase the frequency of the crushing event by increasing the rotational speed of the spindle, and then properly control the needle-like content of the sand and gravel.

In addition, we can increase the frequency of the crushing event by improving the structural parameters of the cone to reduce the amount of needle-like particles in the broken product.

Regardless of whether it is in the field of highway construction or in the field of basic construction, the requirements for the grain shape and the needle-like content of sand and gravel are getting higher and higher. Therefore, in order to remain invincible in the fierce market competition, the cone crusher must be able to reasonably control the needle-like content of the sand and stone material to ensure the grain quality of the product.
