Cone Crusher Crushing Process

The cone crusher crushing process is a widely used method for reducing the size of hard and abrasive materials like rock and ore. It utilizes a gyrating mantle (or crushing cone) within a bowl-shaped crushing chamber. H

Process

Material Feed:

Source: Material is typically fed to the cone crusher from a primary crusher (like a jaw crusher) or directly from a stockpile.

Methods: The material is typically fed via:

Conveyor belt: This is the most common and efficient method for continuous feed.

Vibrating Feeder: Provides controlled and consistent feeding, preventing surges and ensuring even material distribution.

Direct Feeding: Sometimes, material is directly dumped into the crusher hopper by trucks or loaders.

Process

Crushing Chamber:

Design: The crushing chamber consists of two main components:

Mantle (Crushing Cone): A wear-resistant cone-shaped component that gyrates (eccentrically rotates) within the bowl. The mantle is typically made of manganese steel or other high-strength alloys.

Bowl Liner (Concave): A stationary, bowl-shaped component with a wear-resistant liner against which the mantle crushes the material. Bowl liners are also usually made of manganese steel or similar alloys.

Process

Crushing Action:

Gyratory Motion: The mantle gyrates within the bowl liner, creating a progressive crushing action. The material is crushed repeatedly between the mantle and the bowl liner as the mantle rotates.

Progressive Reduction: The space between the mantle and the bowl liner gradually decreases as the material moves down the crushing chamber. This progressive reduction ensures efficient and consistent crushing.

Interparticle Crushing: Cone crushers are known for promoting interparticle crushing, where rocks rub against each other causing size reduction. This leads to a more cubical product shape, which is desirable in many applications (e.g., concrete aggregate).

Process

Discharge:

Bottom Opening: Crushed material exits the crusher through an opening at the bottom of the crushing chamber.

Size Control: The size of the discharge opening determines the final product size. This opening can be adjusted to fine-tune the output.

Screening: After crushing, the material typically goes through a screening process to separate it into different size fractions. Oversized material may be returned to the crusher for further reduction (closed-circuit crushing).

Cone Crusher Working Principle

Components

Outer Fixed Bowl (Crusher Body): A stationary, truncated cone-shaped shell. The inner surface of the bowl is lined with a wear-resistant concave mantle.

Inner Moving Cone (Crushing Head): A truncated cone that sits inside the bowl. The outer surface of the cone is lined with a wear-resistant cone mantle. This cone is the key moving part.

Eccentric Shaft (Eccentric Bushing/Sleeve): A rotating shaft beneath the crushing head. The crucial part that provides the gyratory motion.

Drive System (Motor, Belts, etc.): Supplies the power to rotate the eccentric shaft.

Adjustment Mechanism: Controls the gap between the cone mantle and the concave mantle, thereby setting the output product size. This can be hydraulic, mechanical, or a combination.

Support Mechanism: Supports the crushing head and allows for the gyratory motion while keeping it stable. (often includes a spider bearing at the top).

Working Principle

Material Feeding: The material to be crushed is fed into the top of the cone crusher, typically in the center. The material is distributed around the feed opening.

Gyratory Motion: The eccentric shaft rotates. This rotation causes the crushing head (inner cone) to perform a gyratory motion within the fixed outer bowl. The crushing head doesn't fully rotate; instead, it wobbles or oscillates in a circular path.

Crushing Action: As the crushing head gyrates, the gap between the cone mantle and the concave mantle constantly changes.

Closing Stroke: When the crushing head moves closer to the bowl, the material trapped between the two mantles is subjected to intense compression. This high-pressure compression fractures and crushes the rock/ore.

Opening Stroke: As the crushing head moves away, the crushed material falls downward due to gravity.

Continuous Crushing: The gyratory motion is continuous, creating a cycle of closing and opening strokes. This allows for consistent crushing action around the entire circumference of the crushing chamber. The material is crushed in layers, as the inner cone makes each rotation.

Discharge: The crushed material, now smaller in size, continues to move downwards and is discharged from the bottom of the crusher. The size of the discharge opening (gap between the mantles) determines the maximum size of the output product.

Cone Crusher Features

A cone crusher is a type of compression crusher used in mining, quarrying, and aggregate industries for secondary, tertiary, or quaternary crushing stages.

Crushing Mechanism

Uses a rotating cone inside a stationary bowl (concave) to crush material through compression. Material is squeezed and broken between the mantle (cone) and concave, producing a fine and uniform product.

High Crushing Efficiency

Delivers excellent reduction ratios, typically ranging from 6:1 to 8:1. Suitable for processing hard, abrasive materials such as granite, basalt, and quartzite.

Adjustable Settings

Closed-Side Setting (CSS): Allows adjustment of the gap between the mantle and the concave, controlling the output size. Multiple settings for varying product sizes and quality.

Consistent Product Shape

Produces high-quality, cubical aggregates with minimal fines. Ideal for applications requiring specific gradations, such as road construction or concrete production.

Automatic Control Systems

Modern cone crushers often feature advanced automation systems for: Continuous monitoring of crusher performance. Automatic adjustment of settings. Overload protection to prevent damage from uncrushable material.

Versatility

Suitable for crushing various materials, including: Hard rocks. Soft or medium-hard stones. Ores and minerals. Used across mining, construction, and recycling industries.
