What is Compound Cone Crusher?
The compound cone crusher (also known as the Symons cone crusher) is a high-efficiency secondary and tertiary crushing machine. It uses an eccentrically gyrating mantle to crush material continuously between the mantle and the fixed concave bowl liner, producing well-shaped, cubical aggregate with a minimum of flat or elongated particles.
The “compound” design combines reliable spring overload protection with an optimized multi-cavity crushing chamber. When uncrushable material such as tramp iron enters the chamber, the springs compress to allow the offending material to pass, then the crusher automatically returns to its original setting — protecting the machine and minimizing downtime.
Available in Standard, Medium and Short-Head cavity types, the compound cone crusher covers coarse, medium and fine crushing in one machine family. It is widely used in mining, metallurgy, construction aggregate, railway building and chemical industries for crushing hard and medium-hard ores and rocks such as granite, basalt, iron ore, limestone and quartz.
- High crushing ratio and excellent cubic particle shape
- Spring + hydraulic compound overload protection
- Multiple cavities for coarse, medium and fine crushing
- Low power consumption and long liner life
Why Choose Compound Cone Crusher?
Built for the hardest rocks and the longest production runs — a proven solution for high-output crushing circuits.
High Crushing Efficiency
Optimized crushing chamber geometry and high-speed gyratory motion create interparticle crushing, giving excellent cubic product shape with a high percentage of fine fractions.
Durable Wear Parts
The mantle and concave are cast from high manganese steel with deep profiles, providing excellent wear resistance and long service intervals in abrasive hard-rock applications.
Low Operating Cost
High throughput per kW installed, reliable bevel-gear drive, and easy liner replacement keep downtime and total cost of ownership low.
Versatile & Reliable
Standard, Medium and Short-Head cavities plus a wide range of discharge settings let one crusher family handle coarse aggregate, manufactured sand and fine ore crushing.
Product Features
Engineering details that make the compound cone crusher a trusted workhorse in crushing plants worldwide.
Compound Protection System
Spring stack and robust frame provide instant overload protection. Tramp iron or excessive feed forces are absorbed and the crusher automatically resets.
Advanced Crushing Chamber
Multi-cavity geometry promotes interparticle crushing, producing consistently cubical product and reducing flaky or elongated particles.
Bevel Gear & Eccentric Drive
Precision spiral bevel gear and bronze eccentric bushing deliver smooth, high-torque gyratory motion with low vibration and long bearing life.
Easy Maintenance & Safety
Dry-oil or water-sealed dust-proof system, centralized lubrication, and safe access points for liner replacement and routine inspection.
Working Principle
The compound cone crusher crushes material between a fixed concave (bowl liner) and a gyrating mantle using continuous squeezing and bending action.
- Raw material enters the crusher through the feed opening at the top of the main frame.
- Material falls into the annular crushing chamber between the fixed concave and the moving mantle.
- The main shaft gyrates eccentrically, driven by the bevel gear and eccentric assembly, causing the mantle to move in a circular path.
- Rock is squeezed and bent repeatedly between the concave and mantle, fracturing along natural fissures through interparticle crushing.
- If tramp iron enters the chamber, the spring protection system allows the mantle to rise and the object to pass, then the mantle returns to position.
- Crushed material of the desired size discharges through the adjustable bottom opening and is conveyed to the next process.
The discharge opening can be adjusted to control final product size — from coarse aggregate to manufactured sand.
