A mobile crusher is a device that performs crushing and screening operations in the construction and mining industries, operating on-site. These devices significantly reduce transportation and labor costs by allowing the crushing process to be conducted directly where the material is extracted. Closed circuit mobile crushers are systems that ensure the material produced after the initial crushing process is fed back into the system for further crushing to achieve the desired size.

Features of Mobile Crushers:

Mobile crushers offer various features depending on the types of rocks and processing needs. They generally include crushers (jaw crusher, impact crusher, cone crusher) and screening systems (vibrating screen). These machines extract materials from the primary stone processing areas, conduct crushing operations, and improve production efficiency.

The most important feature of closed circuit mobile crushers is that the material produced after crushing is sent back into the system to be re-crushed. This ensures the material is processed homogeneously to the desired size.

Advantages of Closed Circuit Systems:

  1. Efficiency: Closed circuit systems provide more homogeneous and high-quality results by reprocessing the material produced after crushing.

  2. On-Site Operation: Due to their mobile nature, these machines do not require additional transportation to the site for material crushing.

  3. Less Environmental Impact: Since the material can be reprocessed, it reduces the amount of waste generated, minimizing environmental impact.

  4. Reduced Labor Costs: Mobile crushers reduce the number of operators and transportation costs, lowering labor expenses.

Applications of Closed Circuit Mobile Crushers:

  • Construction Industry: Used to crush large rocks on construction sites and turn them into usable materials.

  • Mining: Very effective for processing and recycling materials in mining areas.

  • Environmental Projects: Used for processing natural stones and producing materials in various environmental management projects.

Working Principle of Mobile Crushers:

Closed circuit mobile crushers operate on a three-stage process: crushing, screening, and re-crushing. In the first stage, rocks are processed by crushers to reduce their size. Then, using screening systems, unwanted materials are separated, and the remaining material is sent back into the system for re-crushing. This closed-circuit system ensures the process is continuous and operates with high efficiency.
