Cone Crusher Introduction

🔧 1. Working Principle

1. Core motion mechanism: The motor drives the eccentric sleeve to rotate through the transmission shaft, so that the moving cone (crushing cone) performs a pendulum motion around the fixed point, periodically approaching and moving away from the fixed cone (rolling mortar wall).
2. Crushing process: After the material enters the crushing chamber, it is squeezed, impacted and bent between the moving cone and the fixed cone, achieving laminated crushing (the material is crushed under the combined action of squeezing and shearing) to form a product of uniform particle size.
3. Overload protection:
Overload protection of spring cone crusher: When foreign matter enters, the spring is compressed to enlarge the discharge port to discharge foreign matter
Overload protection of hydraulic cone crusher: The hydraulic system automatically adjusts the position of the moving cone to expand the discharge port, and automatically resets after the foreign matter is discharged

📊 2. Main types and characteristics

1. Classification by structure (main)
a. Spring cone crusher
Overload protection and discharge port adjustment are achieved through springs
Simple structure, low maintenance cost, but low adjustment accuracy
b. Single-cylinder hydraulic cone crusher
Structure: Single hydraulic cylinder integrates adjustment of discharge port, overload protection and cavity clearing functions
Advantages: Compact structure, fast response speed, suitable for medium and fine crushing
c. Multi-cylinder hydraulic cone crusher
Structure: Multiple hydraulic cylinders are distributed around the machine body to coordinately control the crushing force and discharge port
Advantages: Uniform distribution of crushing force, better product particle shape, suitable for fine and ultra-fine crushing operations
2. Other classification dimensions
a. By purpose: coarse crushing type (such as gyratory crusher), medium crushing type, fine crushing type
b. By cone inclination: steep cone type (large crushing force), gently inclined cone type (high processing capacity)
c. Press cone support method: suspended shaft type, fixed shaft type, etc.

💎 3. Trends

Hydraulic cone crushers (especially multi-cylinder types) have gradually become mainstream due to their high degree of automation and strong controllability of particle shape. The new generation of models optimizes energy consumption and product uniformity through the principle of lamination crushing, such as the constant discharge port design to ensure stable particle size.
