Spindle cone crusher design calculation

Cone crusher is one of the large-scale concentrator device, which plays an important role in mineral processing operations. Development of the times and technology to promote awareness of the cone crusher design and manufacture of continuous improvement. The spindle is one of the main parameters of the cone crusher, the crusher to guarantee the normal operation of the crusher and improve the ability is important, so the spindle design is an important issue.

Cone crusher spindle design will first need to determine which of the forces. Crusher work, due to manufacturing, installation, maintenance and other reasons, often under pressure in the spindle taper bushing mouth situation. Spindle design, the spindle is usually in the worst case as a spindle stress state, according to withstand the maximum crushing force and normal force to crush two kinds of concentrated loads to calculate the strength of the spindle.
Depending on the spindle diameter dangerous section of the crusher precession angle, cone bushing size and structure of the spindle and taper bushing top and the bottom gap, you can determine the diameter of the lower end of the spindle. Size in the axial direction of the upper part of the spindle bore and movable cone fitted parts can be determined according to the design of the crushing chamber and the cone size is determined with reference to actual data. Spindle fitted with cone bore diameter according to the actual site data to determine. Dynamic cone and spindle bore H7 / S6 with, the effect is better. In addition, the spindle and move the cone interference fit of the binding force of the proof can reference.

Design of the spindle, should pay particular attention to: increase moderately rounded surface of the transfer of different diameters; if conditions allow, in the sphere cone and the spindle with increased portions on both sides of the relief groove, such as H series cone crusher cone and spindle with spherical formed with relief groove; guarantee the necessary manufacturing precision and surface roughness, should try to reduce stress concentration. Reasonable spindle structure designed to reduce the gap cone crusher performance and technology at home and abroad.
