The discharge particle size of the spring cone crusher directly affects the crushing effect. The key factors include the clearance of the eccentric components, the stability of the dynamic cone operation and the shape of the liner structure. Optimizing these parameters can significantly improve the crushing efficiency and material quality.

Spring cone crushers are widely used in mining, metallurgy, building materials and other industries, and are responsible for crushing materials such as ore, slag, and rock. The discharge particle size has a significant impact on its working performance and application range, so in-depth analysis of the factors affecting the discharge particle size of the spring cone crusher is of great practical significance.

1. The matching clearance of the eccentric component

When the spring cone crusher is running, the motor drives the eccentric sleeve to rotate with the help of the transmission component. At this time, the main shaft connected to the dynamic cone body and with a taper, driven by the eccentric sleeve, moves around the center of the crusher frame to make a conical surface, so as to achieve the purpose of crushing the material. It should be noted that if the discharge port of the cone crusher is adjusted to be smaller than the specified size, the dynamic cone liner and the fixed cone liner will collide during operation. In reality, the actual adjustable discharge port of the spring cone crusher is different from the theoretical value. This is because the wear of the mating parts increases the gap, or the installation, repair and adjustment are improperly operated and errors are generated.

2. Unstable operation of the moving cone

The unstable operation of the moving cone is caused by the problem of the design, manufacturing or installation and adjustment of the spring cone crusher. When the crusher is running, it will show abnormal movements such as jumping and tipping of the moving cone in the spherical bearing. When the cone crusher operates abnormally, the moving cone jumps or tipped in the spherical bearing, and the distance between the moving cone liner and the fixed cone liner no longer changes from large to small or from small to large normally, but becomes large and small.

This abnormal situation will bring two adverse consequences: first, it is difficult to adjust the discharge port to a normal small value; second, the way the crusher crushes the material changes from "rotational extrusion" to "impact extrusion", resulting in an increase in the needle-like shape of the crushed material, affecting the crushing effect.

3. The shape of the liner structure

A reasonable spring cone crusher liner shape can obtain a better discharge particle size. The determination of the ideal liner shape should be based on factors such as the hardness of the crushed material, product output, and the shape of the liner after wear. It can only be obtained through long-term practical experience and experimental exploration.
