From the primary processing of raw minerals in mining to the production of aggregates in the building materials industry, the performance of crushing equipment directly affects the efficiency and cost of the subsequent process. Cone crusher, by virtue of its unique principle of laminar crushing and stable mechanical structure, has gradually become the priority option for users in many fields.
What Is A Cone Crusher?
It is a kind of crushing equipment that exerts squeezing and bending force on materials through the cyclic rotary oscillation motion of the moving cone and the fixed cone, and is mainly used for crushing medium and high hardness materials (e.g. granite, iron ore) to medium and fine grain size (usually 5-20mm).
It is the ‘intermediate hub’ of mining, building materials, environmental protection, and other industries – not only to undertake further processing after coarse crushing, but also to provide qualified raw materials for subsequent screening, sand making, and other links.
Cone Crusher Working Principle
Then how does a cone crusher work? As can be seen from the following video that the working nature of the cone crusher is to crush large materials to the target size through the periodic extrusion, shearing and grinding of the moving cone and the fixed cone. The specific process can be divided into four stages:
- Feeding and preliminary stratification: The material falls into the top of the crushing chamber from the inlet, and is initially pushed into the gap between the two cones through the “V-shape crushing chamber” formed by the rotating dynamic cone and the stationary fixed cone.
- Laminar crushing: the dynamic cone is driven by the eccentric sleeve to do the rotary oscillation movement, the material is repeatedly squeezed in the multiple contacts between the dynamic cone and the fixed cone. When the pressure on the material exceeds its strength limit, it will be broken along the disintegration surface or fissure to form smaller particles.
- Discharge and Screening: The crushed material, driven by the rotating cone, slides downward along the fixed cone liner and is finally discharged from the discharge opening at the bottom of the crushing chamber. The width of the discharge opening can be adjusted by hydraulic cylinder or spring device to control the size of the finished product.
- Overload protection: When encountering unbreakable foreign objects such as iron blocks, the hydraulic system (or spring system) will instantly release the pressure, so that the moving cone will move back to avoid foreign objects, avoiding damage to the equipment, and then automatically reset to continue working.

3 Minutes to Help You Select A Reliable Cone Crusher
After reading the parameters of different models of cone crusher, how do we choose in the actual application?
APC-D Single Cylinder Hydraulic Type:
Suitable for high quality sand making of gravel aggregate. It should be noted that when the iron content of the material is >5%, it is necessary to install an iron remover, and at the same time, it is necessary to avoid frequent overloading of the hydraulic system, which may lead to seal failure.
APC-M Multi-Cylinder Hydraulic Type:
Suitable for high intensity crushing in large mines with low failure rate. In order to prevent high temperature leading to the decline in viscosity of the hydraulic oil, seal aging, need to stop immediately when the oil temperature exceeds 55 ℃.
APC-C Compound Type:
Suitable for medium-sized crushing lines, with lower maintenance costs than purely hydraulic models. The spring pre-pressure needs to be checked regularly to avoid the hydraulic cylinder being subjected to unilateral force for a long period of time, resulting in partial grinding.
APC-S Spring Type:
If your budget is low, you can choose this model, which has the lowest initial cost. However, be careful not to use it for concrete crushing containing rebar, as rebar jamming cavities can cause the main shaft to break.
Now, I’m sure you can already choose the right crusher for your project. And if you want to know the price of cone crusher, welcome to leave a message to us.
4 Steps to Increase Cone Crusher Actual Output by 30%
After choosing the right crusher, how to improve the actual capacity in the actual use process? Here are some tips for you to:
01Stabilise the discharge opening parameters:
CSS (tight side discharge opening CSS) directly determines the finished product size and throughput.
Operation points:
- Test every shift: Use a special ring gauge to measure CSS and adjust it immediately when it is worn out.
- Constant setting: Avoid frequent adjustment of CSS. 10-25mm is recommended for secondary crushing and 3-10mm for tertiary crushing (depending on the model).
02Achieve continuous “full chamber” operation:
Under full material condition, the materials squeeze each other and grind the edges, and the output rate of cubes is >90%, and the content of needles and flakes is reduced at the same time. Key measures:
- Feed quantity control: the current monitoring method ensures that the power reaches 75%-95% of the rated value.
- Buffer bin optimisation: Variable speed feeders (e.g. plate vibrating feeders) are used to reduce material retention and increase capacity by 10%.
03Fine control of feeding characteristics
Control of fines content: for secondary crushing, the upper limit of fines is ≤25%; for tertiary crushing, the upper limit of fines is ≤10%.
Particle size and height control:
- Uniform mixing: staggered feeding of large and small particle size materials to prevent compaction and plugging of small materials on the centralised side.
- Drop ≤ 0.9 metres: too high impact easily lead to over-limit of crushing force, adjusting ring jumping (especially for small and medium-sized equipment).
04Dynamic monitoring of equipment limit parameters
Upper limit of throughput
- Manifestation: overflow of material at the inlet.
- Measures: Keep the chamber full but not overfilled.
Power limit
- Performance: Motor overload and heat generation.
- Measures: Slightly increase CSS when power > 95% of rated value.
Core Advantage – 3 High and 3 Low
Compared with jaw crusher, impact crusher and other mainstream equipment, the advantages of cone crusher can be summarised as “3 high and 3 low”:
1. High Crushing Efficiency, Low Energy Consumption
Laminar crushing principle + large eccentric distance design, so that in the same processing capacity, energy consumption is reduced by 15%-20%; and the application of the hydraulic system further improves the stability of continuous operation (downtime <2 hours/month).
2. High Product Precision, Low Maintenance Cost
The short head cavity with high chrome alloy liner can control the needle flake particles of the product within 10% to meet the demand of high grade concrete aggregate; meanwhile, the automatic discharging function of the hydraulic system reduces the manual intervention, and the service life of the liner can be extended by 300 hours.
3. High Adaptability, Low Working Condition Limitation
Whether it is soft rock with compressive strength of 30MPa (such as marl) or extremely hard rock with 350MPa (such as granite), the cone crusher can achieve accurate crushing by adjusting the cavity, speed or discharge opening, and the applicable scenes cover many fields such as mining, building materials, metallurgy, chemical industry, and so on.
These advantages make the cone crusher widely used in many industries.
