The Mobile 90 secondary crusher is an essential piece of equipment in rock crushing and processing operations. The term "secondary crusher" indicates its role in the second stage of the crushing process. This means it is designed to further break down rocks that have already been processed by primary crushers, resulting in smaller and more uniform sizes.

The Mobile 90 secondary crusher is particularly effective in processing medium to hard rocks such as limestone, basalt, dolomite, and granite. Due to its mobility, it can be easily transported between work sites, offering flexibility in various applications.

Regarding its working principle, the machine utilizes high-speed rotors and wear-resistant hammers to crush rocks into smaller fragments. Once the material enters the feeding hopper, it is impacted by the rapidly rotating hammers on the rotor. The crushed material is then screened through filtering systems to achieve the desired particle sizes before being distributed for further use.

Advantages of the Mobile 90 secondary crusher:

  • High crushing capacity and efficiency

  • Mobility for easy transportation

  • Adjustable output sizes for different project requirements

  • Low energy consumption with optimized fuel use

  • Wear-resistant components for extended operational lifespan

However, there are also some disadvantages:

  • Wear parts (hammers and screens) require regular maintenance

  • Noise and vibrations necessitate safety precautions in work environments

  • Although mobile, it may face challenges in extremely rough terrains

Mobile 90 secondary crushers are widely used in quarries, concrete recycling plants, mining sites, and large construction projects. They play a crucial role in aggregate production.
