Comprehensive Guide to Closed Circuit Tertiary Crushing and Screening Plants

Closed circuit tertiary crushing and screening plants are integral components in modern aggregate production, particularly in the construction and mining industries. These plants are designed to process materials into specific sizes, ensuring high-quality aggregates suitable for various applications.

What Are Closed Circuit Tertiary Crushing and Screening Plants?

These plants operate in a closed-loop system, where the material is continuously processed until it reaches the desired size. The process involves several stages:

1. Primary Crushing: The initial reduction of raw material size.

2. Secondary Crushing: Further reduction to achieve intermediate sizes.

3. Tertiary Crushing: Fine crushing to produce the final desired sizes.

4. Screening: Separation of materials into different sizes using vibrating screens.

5. Recycling: Returning oversized materials back into the system for further processing.​

Key Components

• Tertiary Crushers: Typically impact crushers or cone crushers that provide fine material output.

• Vibrating Screens: Separate materials into different size fractions.

• Conveyors: Transport materials between different stages of the plant.

• Dust Suppression Systems: Minimize airborne dust during processing.

• Control Systems: Monitor and adjust plant operations for optimal performance.​

Advantages of Closed Circuit Systems
