What types of crushers are there and how they work?

Crushing equipment is an indispensable component in processes such as stone crushing, sand making, and grinding. However, with so many types of crushers currently available on the market, how can you choose the right one? First, you need to be familiar with the applicable conditions and advantages of these mainstream types of equipment!

Before understanding crushers, it's important to have a basic understanding of crushing methods:

Crushing Methods

Crushers use a variety of crushing methods, including extrusion, splitting, breaking, shearing, impact, or striking. These methods are generally a combination of these, with no single method being used.

Extrusion Crushing: The working surfaces of the crusher apply pressure to the material trapped between them. When the compressive stress reaches its compressive strength limit, the material breaks.

Split Shear Crushing: The edges of the crushing surface wedge into the material, generating tensile stress. When this stress exceeds the material's tensile strength limit, the material splits, and powder is generated locally at the contact point between the sharp edge and the material.

Bending, breaking and crushing: The materials sandwiched between the working surfaces are like simply supported beams or multi-supported beams subjected to concentrated forces. The materials are mainly subjected to bending stress, but are also subjected to splitting at the contact point of the working surfaces. Extrusion and shear crushing: A combination of extrusion and shear crushing.

Impact crushing: Impact crushing involves the impact of the high-speed crushing element on the material being crushed, the impact of the high-speed material against a fixed wall, and the mutual impact of the moving materials.

The G10 portable handheld pneumatic crusher is powered by compressed air. Compressed air is distributed alternately to both ends of the cylinder via a valve, causing the hammer to reciprocate and impact the backing hammer against the end of the steel chisel, driving the chisel into the concrete layer and breaking it into pieces. Durable, high-performance, and easy to operate, it is a classic crushing tool. It boasts higher output power than comparable products and can crush materials of varying hardness, making it suitable for a wide range of applications. Each component is precision-engineered, ensuring a long service life for spare parts. The weight of the machine overcomes 80% of the rebound force, ensuring comfortable operation.
