Cone Crusher Lamination Crushing Principle

What Is Lamination Crushing?

When the solid raw materials are under some certain pressure, pressure distortion will occur. And when the pressure reaches to a certain degree, the particles will breaks and cracks in the weakest place. The concept of lamination crushing is that the crushing of rocks not only occurs between particles and scale board but also between particles and particles.

How To Achieve Lamination Crushing?

In order to achieve lamination crushing, certain prerequisites must be met:

(1)Full feeding: only by full feeding can a certain number of material layers be formed and the lamination crushing effect can be realized. And when the number of crushing layers is 6-10, it will save energy and has high crushing output

.

(2) uniform feeding: uniform feeding will make the raw material stress distribution reasonable, and then make cone crusher work stable;

(3) uniform particle size: because when the geometric size of the material particle size is very different, the small material will protect the large material from being broken, that is, the fine particle protection phenomenon, so in order to avoid the occurrence of this phenomenon, the feeding particle size should be uniform;

(4) Filling degree: when the raw material filling rate is too small, there will be powdery particles,resulting in a certain amount of waste, thus reducing the effect of lamination crushing; When the filling rate is too large, the raw material is too tight and easy to agglomerate, which is not conducive to the crushing. Therefore, a series of tests show that the filling rate between 0.55 and 0.75 is the most favorable for the lamination crushing.

Advantages And Features Of Lamination Crushing

Raw materials are crushed between concaves and mantle. While crushing, materials are under squeezing and shearing force, very easy to be crushed. In this case, the energy consumption is relatively low. The final products of lamination crushing are in good cubical shape. Adopting specially designed crushing cavity according to lamination principle and its matching speed instead of the tradition crushing principle, we can alternatively crush the raw materials. In this case, the crushing ratio and cubical particles content are sharply increased.

Cone crushers with lamination crushing principle can form a maskant, which not only effectively reduce the damage of wear parts, but also reduce the needle-like particles content.

Attentions In Using The Crushing Cavity

The efficient lamination crushing cavity should combine with evenly and fully feeding condition in order to give full scope.

Different crushing cavities are suitable for different working conditions. And the crushing cavity should match the specification of cone crusher.

The crushing ratio beard by crushing cavity is fixed. If the crushing ratio is too high, there might be blocking in cone crusher.

In the operation process, crushing cavity will damage, which will lead to the increasing of discharge opening and the size of final products will also increase. In serious cases, the crushing cavity even deforms, which will greatly reduce the crushing efficiency. So operators should pay attention to the wear degree of crushing cavity. Once found damage, operators should adjust or change them timely.
