Different Types of Crushers You Must Be Aware Of

Rocks, stones, and ore are reduced in size using crushers. They are frequently used in mining operations, recycling of building materials, and aggregate manufacture. For any size reduction need, there are several product lines to choose from, which include various gyratory crushers, jaw crushers, cone crushers, and impact crushers. 

Two categories can be used to categorize all rock crushers. Impact crushers use the principle of fast impacts to crush the material, as opposed to compression crushers that push the material until it breaks. The compression principle governs how jaw, gyratory, cone, and hammer crushers function. The impact concept is then applied by impact crushers.

Jaw Crushers

Primary crushers typically use jaw crushers. Their major goal is to shrink the material down to a size where it can be carried on conveyors to the following crushing stages. 

Jaw crushers, as their name suggests, use a fixed jaw and a moving jaw to smash the rock and other materials. The fixed jaw remains in place while the moving jaw is positioned on a pitman that reciprocates. The two jaws compress larger stones into smaller ones as the material passes between them. 

Gyratory Crushers 

In the first crushing stage and slightly less common in the secondary crushing stage, gyratory crushers are regularly used. The gradation of the crushed material can be controlled since the gyratory crushers have a hydraulic setting adjustment mechanism. 

A rotating shaft is a feature of gyratory crushers. Between an internal moving element (mantle) installed on the oscillating shaft assembly and an external fixed element (bowl liner), the material is reduced in a crushing cavity.

Cone Crushers 

From a technological perspective, cone crushers are similar to gyratory crushers, however, unlike gyratory crushers, cone crushers are widely used in the secondary, tertiary, and quaternary crushing stages. However, occasionally the processed material’s grain size is sufficiently tiny by nature that the usual primary crushing stage is not required. Cone crushers can perform the initial stage of the crushing process in these circumstances as well. 

Material is crushed in a crushing chamber of a cone crusher between an external fixed element (bowl liner) and an interior moving element (mantle) installed on the oscillating shaft assembly. 

Hammer Crushers 

Impact crushers are adaptable crushers that can be applied at any point in the crushing procedure. The capabilities and features of various impact crusher types do, however, differ greatly. 

Vertical shaft impact (VSI) crushers and horizontal shaft impact (HSI) crushers are the two basic categories into which impact crushers are typically categorized. Although these various impact crusher types use the same impact-based crushing principle to lower the size of the material, their features, capacities, and ideal applications range greatly.

Key Takeaway

Many fascinating and practical devices are prevalent in the realm of heavy machinery, such as the road roller, crane, and even the bulldozer. The crusher is one such device, nevertheless, that is generally undervalued. The majority of people are unaware that, despite what it may appear like, crushers have a wide range of applications outside of the building industry.
