Spring Cone Crusher Core Overview


The spring cone crusher, also known as a spring-type cone crusher, is a traditional, classic, and widely used cone crusher. Its core feature is the use of a spring device for overload protection and discharge opening adjustment.


Main Structure and Working Principle


Core Structure:


• Crushing Chamber: Composed of a moving cone and a fixed cone, where materials are squeezed, bent, and crushed.
• Spring System: Multiple sets of large springs on the machine's perimeter. This is its defining characteristic and the most obvious difference from a hydraulic cone crusher.
• Transmission Device: The motor drives the moving cone to perform an eccentric oscillating motion via pulleys, a horizontal shaft, and bevel gears.


Working Principle:


• Crushing: The motor drives the moving cone to perform an eccentric oscillating motion, periodically approaching and moving away from the fixed cone, achieving compression and crushing of the material.
• Overload Protection: When an uncrushable object (such as an iron block) enters the crushing chamber, the abnormal increase in force on the moving cone forces it to rise, compressing the spring and instantly widening the discharge opening, allowing the foreign object to be discharged. Then, the spring's restoring force returns the moving cone to its original position. This process is passive and mechanical.
• Discharge opening adjustment: By raising or lowering the adjusting sleeve using an adjusting device, the position of the fixed cone is changed, thereby altering the discharge opening size. Adjustment requires stopping the machine and is relatively cumbersome.

HP300 Multi-Cylinder Hydraulic Cone Crusher

How to achieve efficient, stable, and high-quality crushing when facing the hardest rocks in mines and aggregate production sites?



The core secret of the HP300 cone crusher lies in its revolutionary 'multi-cylinder hydraulic' design. Unlike traditional spring cone crushers, the HP300 provides crushing force and adjustment through multiple hydraulic cylinders surrounding the main shaft.


This offers three major advantages:
- First, exceptional stability, with the main shaft firmly secured for smoother operation.
- Second, convenient adjustment, allowing for precise adjustment of the discharge opening size with the push of a button, easily enabling automated control.
- Third, unparalleled protection against tramp iron;

when encountering unbreakable foreign objects, the hydraulic system can instantly release pressure and give way, protecting the main machine from damage, and then automatically reset, with virtually no impact on continuous production.

Introduction to Impact Crusher

An impact crusher is a high-efficiency crushing equipment that utilizes impact energy to crush materials. It is widely used in mining, building materials, chemical, and metallurgical industries, and is one of the core pieces of equipment in secondary (medium) and tertiary (fine) crushing processes.

Core Working Principle

The core working principle of the impact crusher is "impact crushing." Its basic process is as follows:

1. Feeding and Acceleration: Material enters the machine through the feed inlet and first falls onto the high-speed rotating rotor.
2. Impact and Projection: Hammers are firmly installed on the rotor. The hammers grab the material and project it at high speed along the tangential direction of the rotor.
3. Impact Crushing: The high-speed projectile material first impacts the impact plate above the machine cavity, resulting in the initial violent impact and crushing.
4. Repeated Collision and Shaping: The crushed material is rebounded back into the rotor's action zone, where it is again impacted and projected by the hammers, undergoing multiple and repeated collisions with the impact plate or other freely falling material. This process continues until the material particle size is smaller than the gap between the bottom grate bars or the discharge port, and is finally discharged from the machine as the finished product.

This combination of "stone-on-iron" and "stone-on-stone" crushing methods is the fundamental reason for its high-efficiency crushing and high cubic product yield.

PE600x900 Jaw Crusher

In numerous fields such as mining, aggregate production, and construction waste treatment, primary crushing (coarse crushing) is the "choke point" of the entire production process. Its efficiency and stability directly determine the smoothness of subsequent processes and the economic benefits of the final product. Among many primary crushing equipment, there is a shining star that has withstood decades of market testing and is still widely chosen by customers worldwide—the PE 600×900 jaw crusher.

What materials can a double-stage hammer crusher crush?

The double-stage hammer crusher is a widely applicable medium and fine crushing equipment, particularly adept at handling medium-to-low hardness materials with a compressive strength below 200MPa. It can efficiently crush common mining and building material raw materials such as limestone, bluestone, coal gangue, and gypsum, and easily handle materials containing a certain amount of moisture. Its unique screenless design fundamentally solves the industry problem of wet material clogging. Furthermore, it is also suitable for crushing solid waste such as coal, slag, and mineral slag, achieving "one machine for multiple uses." While ensuring uniform output fineness (generally below 2-3mm), it significantly improves production efficiency and economic benefits.
