Analysis of the forces in a cone crusher shows that, in certain conditions, the material in the crushing chamber is subjected not only to compressive forces but also to a torque. In that case, a complex stress state appears in the material. Correspondingly, normal stress and tangential stress appear in the piece.

Even though the original cone crusher patents were accepted almost 100 years ago (in the mid 1920's by E B Symons), the cone crusher concept continues to be an outstanding success. Cone crushers are in common use wherever crushing is required. Cone crushing for aggregate production far exceeds all other applications including mineral processing.
such as ore. Therefore, the study of crusher is more focused on the research and simulation analysis of discrete element theory[1]. In addition, when the movable cone liner is worn out, the discharging port will be enlarged, the ore-discharging granularity becomes thicker, and the crushing efficiency is affected.
These crushers are designed so that the head-to-depth ratio is larger than the standard gyratory crusher and the cone angles are much flatter and the slope of the mantle and the concaves are parallel to each other. The flatter cone angles help to retain the particles longer between the crushing surfaces and therefore produce much finer particles.
Cone crushers were originally designed and developed by Symons around 1920 and therefore are often described as Symons cone crushers. As the mechanisms of crushing in these crushers are similar to gyratory crushers their designs are similar, but in this case the spindle is supported at the bottom of the gyrating cone instead of being suspended as in larger gyratory …
Cone Crushers. The Symons Cone Crusher has come into almost universal use during the last few years for the final stage of crushing. It is a development of the secondary gyratory crusher, which is merely a small gyratory crusher designed to break the product of the primary machine down to about 1½-in. size; but the main shaft of a cone crusher instead of …

Analysis of Common Failures and Causes of Cone Crusher author:dahua1 time: 1.Cracking sound when breaking ore. main reason: The working mechanism of the cone crusher is composed of a crushing cone with a liner and an adjusting ring. A layer of zinc alloy is cast between the cone of the crushing cone and its liner, and between the ...
This method applies to other crushers where a control variable is available The crushers are the last size reduction stage in the value chain. Over crushing is common. The connection between crusher setting and yield is often unknown The rock cannot be repaired. We need to control the crusher carefully.
• In a cone crusher the stones are crushed with both SPB and IPB as the material moves down through the chamber. • The relative amounts of IPB and SPB depends on factors like chamber design, crusher geometry, speed, css, eccentric throw, and others. SPB IPB Fines Less More Shape Flaky Cubic Force Low High Crusher Capacity
Cone crushers are the most commonly used crusher type for secondary and tertiary crushing stages in both the aggregate and the mining industry. Due to the vast number of active operating crushers in the world, a very strong global common incentive is to maximize

The key step of wear failure analysis is to analyze the morphology of the wear surface, so the sample must be taken from the fresh wear surface of the wear debris. The moving cone (liner) we sampled was just removed from the cone crusher and shipped back in time. The broken cone crusher liner is cut into large samples by oxygen-acetylene flame ...
