Cone Crusher

Product Overview

About the Cone Crusher

The cone crusher is a secondary and tertiary crushing machine that reduces material by compressive force between a mantle (moving) and a concave liner (fixed) inside a cone-shaped crushing chamber. As the mantle gyrates around the main shaft, material is continuously compressed and fractured until it is small enough to pass through the discharge opening.

In cement plants, cone crushers typically follow the primary jaw crusher in the crushing circuit, further reducing limestone, granite, basalt, quartzite, and river gravel to the size required by the raw mill. Their ability to produce uniform, cubical product with low flakiness makes them indispensable for high-quality aggregate and cement raw material preparation. LIMING cone crushers serve mines, quarries, and cement plants with capacities up to 1,814 t/h.

Compared to impact and hammer crushers, cone crushers consume less energy per ton when crushing hard and abrasive materials, and their wear parts last significantly longer — making them the economical choice for high-tonnage, continuous-duty operations.

Classification

Types of Cone Crushers

Cone crushers are classified by chamber profile (for different crushing stages) and by the overload-protection mechanism.

By Chamber Type

Standard (Coarse)

Wide feed opening, short parallel zone. For primary/secondary crushing of larger feed up to 350mm. Produces coarser product.

Medium

Balanced chamber for general secondary crushing. Middle ground between standard and short head for medium feed and product size.

Short Head (Fine)

Steeper chamber, longer parallel zone for tertiary crushing and sand making. Produces fine, uniform product down to 3-13mm.

By Overload Protection Mechanism

Spring Cone Crusher

Classic design using a spring release system for overload protection and tramp-iron pass-through. Simple, robust, and cost-effective — ideal for budget-conscious operations.

Hydraulic Cone Crusher

Hydraulic cylinders provide automatic overload release, remote discharge adjustment, and one-button chamber clearing. Higher automation, easier maintenance, better product control.

Compound Cone Crusher

Combines spring and hydraulic protection. Optimized chamber design with higher reduction ratio and throughput — a versatile solution for varied feed conditions.

How It Works

Working Principle of Cone Crusher

The cone crusher reduces material by compressive and bending forces between a gyrating mantle and a fixed concave liner. The drive system causes the mantle to gyrate eccentrically, continuously compressing material that enters the crushing chamber from the top.

Material feed: Crushed material from the primary jaw crusher enters the feed distribution plate at the top of the crusher, which evenly distributes it around the crushing chamber.
Gyrating mantle: The electric motor drives the horizontal shaft via V-belts and bevel gears, causing the eccentric sleeve to rotate. This makes the main shaft and mantle gyrate in a circular path inside the concave liner.
Compression crushing: As the mantle moves toward the concave, material is compressed and fractured between the two surfaces. The crushing action is continuous — at any moment, material is being crushed on one side of the chamber while discharging on the other.
Parallel zone: The lower part of the chamber has a parallel zone of controlled length. Particles must pass through this zone at the correct size, ensuring uniform product gradation and cubical shape.
Discharge: Material that has been reduced to below the discharge opening size exits the chamber by gravity. The opening (closed-side setting) is adjusted hydraulically or by shims to control final product size.
Overload protection: If uncrushable tramp iron enters the chamber, the spring or hydraulic system releases the mantle, allowing the object to pass through. The system then resets automatically, protecting the crusher from damage.

Frequently Asked Questions

Cone Crusher FAQ

What is the difference between standard, medium, and short-head cone crushers?

The difference lies in the crushing chamber profile. Standard (coarse) has a wide feed opening and short parallel zone for primary/secondary crushing of larger feed. Medium is for general secondary crushing. Short head has a steeper chamber with a longer parallel zone, producing finer product for tertiary crushing and sand making.

How does a hydraulic cone crusher differ from a spring cone crusher?

Spring cone crushers use a mechanical spring system for overload protection and tramp-iron release. Hydraulic cone crushers use hydraulic cylinders, enabling automatic overload release, remote discharge adjustment, and one-button chamber clearing — offering higher automation, easier maintenance, and better product size control. Hydraulic models are preferred for modern automated plants.

What is the typical capacity range of LIMING cone crushers?

LIMING cone crushers cover a capacity range of 12 to 1,814 t/h depending on model, chamber type, and discharge setting. Small models (PYB-600) produce 12-25 t/h, while large compound models (PYFB-2218) reach 1,000-1,814 t/h for high-tonnage cement and mining operations.

When should I choose a cone crusher over a jaw crusher?

Use a jaw crusher for primary coarse crushing of large run-of-mine material. Use a cone crusher for secondary or tertiary crushing after the jaw crusher, when you need finer product, higher reduction ratio, and more cubical particle shape. Most cement plants use a jaw crusher first, then a cone crusher for intermediate crushing before the raw mill.
