Crushers are primarily used to crush various types of stone materials based on differences in crushing principles and final particle sizes. They are widely employed in numerous sectors, including mining, metallurgy, building materials, highways, railways, water conservancy, and the chemical industry. So, what exactly are the differences among these many types of crushers?

Today, let’s start by discussing the differences among the most commonly used crushers: jaw crushers, impact crushers, and cone crushers.

Jaw crusher Commonly known as the "Epo," also referred to as the "Tiger's Mouth," it is the preferred equipment for primary crushing. It features a large crushing ratio, uniform product particle size, simple structure, reliable operation, easy maintenance, and low operating costs. As a result, it is widely used in numerous sectors including mining, metallurgy, building materials, highways, railways, water conservancy, and the chemical industry. Jaw crushers are extensively employed for crushing various materials with a compressive strength not exceeding 320 megapascals.

Working principle: The working components consist of a fixed tooth plate and a movable tooth plate. The movable tooth plate performs periodic reciprocating motion relative to the fixed tooth plate, during which the material is crushed between the two plates.

Impact crusher Commonly referred to as the “impact crusher,” it was developed much later than the jaw crusher. In the 1850s, with the advancement of productive forces, the jaw crusher could no longer fully meet the demands of crushing technology. Thus, building upon the foundation of the jaw crusher, people designed the impact crusher. Its key features include: compact size, simple structure, large crushing ratio, low energy consumption, high production capacity, uniform product particle size, and selective crushing action.

The impact crusher can process materials with side lengths ranging from 100 to 500 millimeters and boasts a maximum compressive strength of up to 350 megapascals. It offers advantages such as a high reduction ratio and cubic-shaped particle morphology after crushing. The size of the discharge particles is adjustable, and the crusher can handle a wide variety of crushing specifications. It is widely used in industries including building materials, ore crushing, railways, highways, energy, transportation, cement, mining, and chemical engineering for medium- and fine-size material crushing.

Working principle The material is crushed by impact energy. During operation, the rotor of the impact crusher rotates at high speed driven by an electric motor. After the material enters the crusher, it collides with the hammer plates on the rotor, causing it to break into smaller pieces. The broken material is then rebounded onto the lining plates for further crushing, and finally discharged from the discharge port.

Cone crusher They are categorized into “spring cone crushers,” “hydraulic cone crushers,” and “composite cone crushers.” The structural designs of these three types of spring cone crushers are essentially the same; the only difference lies in the shapes of the moving cone and the stationary cone, which results in different cross-sectional shapes of the crushing chamber and consequently leads to variations in the sizes of the feed and discharge materials. Compared with other types of crushing machinery, cone crushers offer advantages such as high crushing efficiency, low energy consumption, and uniform product particle size. They are suitable for crushing raw materials in industries including metallurgy, construction, road building, chemical engineering, and silicate industries, and can handle ores and rocks with medium or higher hardness.

Working principle The rotation of the motor, via pulleys or couplings, a transmission shaft, and a conical section, drives the eccentric sleeve to perform a swinging motion around a fixed axis. As a result, the crushing wall of the cone crusher alternately approaches and moves away from the surface of the stationary lining plate mounted on the adjusting sleeve, causing the ore within the crushing chamber to undergo continuous impact, compression, and bending, thereby achieving ore fragmentation.
