In construction, different types of crushers are used depending on the materials and the specific requirements of the project. Each type of crusher is designed for varying applications and produces specific particle sizes. Here are some common types of crushers:
Jaw Crushers: These are used primarily for heavy mining, quarried materials, and recycling applications. They consist of a fixed jaw and a movable jaw which compresses material as it flows down, ultimately breaking it into smaller pieces.
Gyratory Crushers: Similar to jaw crushers, gyratory crushers work with a conical head and a concave surface, and they are primarily used for heavy mining and very hard rock crushing.
Cone Crushers: These are used for crushing medium-hard to very hard materials. They work by squeezing materials between an eccentrically gyrating spindle and a concave hopper, breaking down the material by repeated impact.
Impact Crushers: These are used for softer materials. They operate by striking materials with high-speed hammers attached to a rotor. They can be divided into two types:
Roll Crushers: These are simple in design with a pair of rotating cylinders that crush the material. They are typically used for coal, softer ores, and sheeting.
Hammermills: These are a type of impact crusher that uses rotating hammers to crush materials. They are very versatile and can be used for a variety of materials.
Jaw and Impact Crusher Combinations: Some machines combine jaw and impact crushing capabilities to handle both primary and secondary crushing processes.
Mobile Crushers: These are versatile machines that can be easily transported to different locations, making them ideal for on-site crushing jobs.
The choice of crusher depends on factors such as the type of material to be processed, the desired size of the final product, and the production capacity required.
