A mobile crusher is a portable stone crushing and screening unit mounted on wheels or tracks, used in mining, recycling, and construction sectors. It can be easily transported to various job sites.

Purpose:
Mobile crushers crush rocks, stones, concrete, and asphalt into reusable aggregates directly at the worksite. This eliminates transportation needs and reduces overall project costs.

How It Works:

  1. Raw material is fed into a feeder hopper.

  2. Initial crushing is performed by a primary impact crusher.

  3. Further refinement by secondary or tertiary crushers.

  4. Material is screened into desired sizes.

  5. Conveyors transport final products to stockpiles.

Applications:

  • Quarrying

  • Infrastructure and road construction

  • Recycling operations

  • Remote mining areas

  • Temporary crushing requirements

What is a Stationary Crusher, What Does It Do, How It Works, and Where Is It Used

Stationary crushers are fixed installations used in large-scale material processing facilities where continuous high-capacity crushing is needed. They are installed on foundations and require longer setup times.

Purpose:
To crush high volumes of hard stones or minerals consistently, producing construction materials like gravel and sand.

How It Works:

  1. Raw materials are delivered via trucks into a feed bunker.

  2. Crushed by a primary impact crusher.

  3. Passed through secondary and tertiary crushers for refinement.

  4. Separated by screening systems.

  5. Stored via conveyor belts.

Applications:

  • Permanent quarry facilities

  • Cement and aggregate production

  • Heavy-duty mining

  • Large construction projects

Differences Between Mobile and Stationary Crushers

  • Mobility: Mobile units can relocate; stationary systems cannot.

  • Setup: Mobile systems are faster to deploy.

  • Capacity: Stationary units typically handle more volume.

  • Flexibility: Mobile crushers adapt better to varying site needs.

  • Cost Structure: Mobile is cost-effective for short-term; stationary suits long-term investment.

What is a Primary Impact Crusher Blow Bar, What Does It Do, How It Works, Where Is It Used

A blow bar in a primary impact crusher is a high-resistance steel or alloy component mounted on the rotor, used to deliver powerful impacts to incoming material.

Purpose:
To apply forceful impact on large stones during the initial crushing phase, effectively reducing them to smaller, processable sizes.

How It Works:

  1. Rotor spins at high RPM.

  2. Material enters the crusher chamber.

  3. Blow bars strike the material forcefully.

  4. Material rebounds off breaker plates, causing further reduction.

  5. Output is sent to screens or secondary stages.

Applications:

  • Primary crushers in mining and quarrying

  • Construction waste recycling

  • High-volume crushing operations

  • Both mobile and stationary plants
