The spring cone crusher is widely used in mining, metallurgy, building materials and other industries to crush ore, slag, rock and other materials. Its discharge particle size determines its working and its application range, so it affects the spring cone The factor analysis of the discharging granularity of the crusher has important practical significance.
    1. Fit clearance of eccentric parts
    When the spring cone crusher is running, the motor drives the eccentric shaft sleeve to rotate through the transmission parts. The main shaft with taper and integrated with the moving cone body is driven by the eccentric shaft sleeve, and its shaft moves on the cone surface around the crusher frame*. , So as to achieve the purpose of crushing materials. If the discharge port of the cone crusher is adjusted to be smaller than the specified discharge port size, the collision between the moving cone liner and the fixed cone liner will occur during operation. In reality, there is a certain gap between the actual discharge opening that can be adjusted by the spring cone crusher and the theoretical discharge opening. The reason is that the gap becomes larger due to the wear of the matching parts, or the error caused by improper installation, repair and adjustment. So.     2. Unstable operation of the moving cone
    Unstable operation of the moving cone refers to a series of abnormal movement states of the spring cone crusher, such as jumping and overturning in the spherical bearing, due to problems in the design, manufacture or installation and adjustment of the spring cone crusher. When the cone crusher runs abnormally and the moving cone jumps or falls over in the spherical bearing, the distance between the moving cone liner and the fixed cone liner does not gradually change from large to small, from small to large, but to suddenly increase Suddenly, in this situation, on the one hand, the discharge port cannot be adjusted to a normal small value. On the other hand, the crusher at this time does not use "rotary extrusion" but "impact extrusion" to crush materials. The crushed material increase in needles and flakes.
    3. The shape of the liner structure
    Reasonable spring cone crusher liner shape can obtain better discharge granularity. ~The determination of the shape of the liner can be obtained based on factors such as the hardness of the crushed material, the output of the product, the shape of the liner after wear, and the summary of long-term practical experience.
