A Four Combinations Mobile Crushing Plant is a highly flexible and efficient crushing system that integrates four main functions: crushing, screening, conveying, and feeding into a single mobile unit. This setup is ideal for medium to large-scale projects requiring high productivity and versatility in processing various materials (e.g., aggregates, ores, construction waste).
Typical Configuration of a 4-in-1 Mobile Crushing Plant
1. Primary Crushing Unit
– Usually a jaw crusher or heavy-duty impact crusher for coarse crushing.
– Handles large feed size (e.g., 600–800mm).
2. Secondary Crushing Unit
– Often a cone crusher or fine impact crusher for intermediate crushing.
– Produces smaller, more uniform particles (e.g., 20–50mm).
3. Tertiary Crushing/Screening Unit
– May include another impact crusher, VSI crusher, or multi-deck vibrating screen.
– Further refines material for final products (e.g., 0–10mm sand or gravel).
4. Return/Feedback Conveyor System
– Recirculates oversized material back to secondary/tertiary units for reprocessing.
– Ensures closed-circuit operation for higher efficiency.
Advantages
✔ All-in-One Mobility: No need for separate machines; reduces transportation costs.
✔ High Flexibility: Suitable for diverse materials (hard rock, limestone, recycled concrete).
✔ Automated Control: PLC systems optimize production and monitor performance.
✔ Quick Setup: Self-contained with hydraulic or electric power options.
Applications
– Quarrying and mining (primary and secondary crushing).
– Construction
ste recycling.
– Road base and railway ballast production.
– Artificial sand manufacturing (with VSI crusher).
