Mobile crushers have revolutionized the way materials are processed and transported on construction sites. They provide flexibility, efficiency, and cost savings by allowing on-site crushing of materials. There are several types of mobile crushers, each designed for specific applications and material types. Here’s an overview of the most common types:
1. Mobile Jaw Crushers
Functionality: Mobile jaw crushers are primary crushers designed to crush large, hard materials such as granite, basalt, and recycled concrete. They are typically used in the first stage of the crushing process.
Working Principle: The jaw crusher features a fixed and a moving jaw plate. The material is fed into the top of the crusher and is compressed between the two jaws, breaking it into smaller pieces. The crushed material then exits through the bottom of the crusher.
Advantages:
- High capacity and efficiency
- Can handle a variety of materials, including very hard ones
- Simple structure and easy maintenance
Applications: Mining, quarrying, recycling of construction waste, demolition projects.
2. Mobile Impact Crushers
Functionality: Mobile impact crushers are used for soft to medium-hard natural stone and for the reprocessing of residual construction materials.
Working Principle: Impact crushers operate on the principle of rapid impact to crush the material. They have a high-speed rotor with blow bars that strike the material, causing it to break along natural fissures. The crushed material is then further reduced by the impact plates inside the crusher.
Advantages:
- Excellent product shape with high reduction ratios
- Capable of producing high-quality end products
- Versatile and can handle a range of materials
Applications: Recycling of concrete and asphalt, quarrying, and demolition operations.
3. Mobile Cone Crushers
Functionality: Mobile cone crushers are used for secondary, tertiary, and quaternary crushing stages. They are suitable for crushing medium to hard materials.
Working Principle: Cone crushers consist of a conical-shaped mantle that rotates within a bowl. The material is crushed between the mantle and the bowl liner through compression. The crushed material is discharged at the bottom of the crusher.
Advantages:
- High throughput and efficiency
- Produces well-shaped aggregates
- Adaptable to different crushing applications
Applications: Aggregate production, mining operations, and recycling of demolition materials.
Each type of mobile crusher has its own set of advantages and is suitable for specific applications. Jaw crushers are excellent for primary crushing of hard materials, while impact crushers are better for medium and soft materials. Cone crushers provide a high degree of control over the product size and are suitable for secondary and tertiary crushing stages. Mobile scalpers and screens enhance the efficiency of crushing operations by pre-screening and sorting materials. The choice of mobile crusher depends on the nature of the material, the desired product size, and the specific requirements of the project.
