a Mobile Rock crusher Plant Work

A mobile rock crusher plant is designed to crush rocks and minerals on-site, eliminating the need for transporting materials to a stationary crusher. Here’s how it works:

1. Components of a Mobile Rock Crusher Plant

A typical setup includes:

• Primary Crusher (Jaw or Impact Crusher) – Breaks large rocks into smaller pieces.
• Secondary Crusher (Cone or Impact Crusher) – Further reduces size for finer output.
• Vibrating Feeder – Regulates material flow into the crushers.
• Conveyor Belts – Transport crushed material between stages and to stockpiles.
• Screening Unit – Separates crushed material by size (e.g., scalping screen, trommel).
• Power Source – Diesel engine or electric motor.
• Mobility System – Tracks or wheels for easy relocation.



2. How It Works

(A) Feeding Stage

• Rocks are loaded into the hopper via an excavator or wheel loader.
• A vibrating feeder ensures steady material flow into the primary crusher.



(B) Primary Crushing

• The primary crusher (usually a jaw crusher) breaks large rocks (~24”–48”) into smaller chunks (~6”–8”).
• Adjustable settings control output size.

(C) Secondary Crushing & Screening

• Smaller rocks move via conveyor to a secondary crusher (cone/impact).
• After crushing, material passes through screens to separate sizes:

– Oversized material may be recirculated back for further crushing.
– Correctly sized aggregate is stockpiled.

(D) Stockpiling & Transport

• Final product is conveyed to stockpiles or directly loaded onto trucks.

3. Advantages of Mobile Rock Crushers

• Portability: Move between job sites quickly (track/wheel-mounted).
• Cost-Efficiency: Reduces hauling costs since crushing happens on-site.
• Flexibility: Can process various materials (limestone, granite, recycled concrete).
• Quick Setup: Self-contained units require minimal installation.
