A mobile crusher is a portable stone crushing and screening unit that can be easily moved from one location to another. It’s typically mounted on wheels or tracks and designed for use in temporary job sites such as construction projects, roadworks, or mining operations.

It operates by feeding large rocks or materials into a crusher unit—jaw, impact, or cone crushers—where the material is broken down into smaller sizes. These crushed materials are then sorted through screening units. Power is usually supplied by diesel engines or mobile generators.

Mobile crushers are highly efficient for short-term projects where mobility, speed, and lower transportation costs are essential. They are widely used in stone quarries, demolition waste recycling, road construction, and infrastructure development.

What is a Stationary Crusher, How Does It Work, Where is It Used

A stationary crusher is a fixed crushing plant installed on a permanent foundation, designed for long-term and high-volume operations. These systems are larger and more robust than mobile units, with a higher production capacity.

Like mobile crushers, they include a feeder, crushing units (jaw, impact, or cone), screening modules, and conveyor belts. However, stationary plants are powered mainly by electricity and often incorporate automation technologies.

They are extensively used in quarries, cement plants, mining operations, asphalt plants, and large-scale infrastructure projects.

Differences Between Mobile and Stationary Crushers

  • Mobility: Mobile units can move between sites; stationary units are fixed.

  • Capacity: Stationary crushers are suited for high-volume production; mobile crushers for flexible and moderate output.

  • Installation: Mobile crushers are quicker to deploy; stationary ones require detailed installation.

  • Energy: Mobile systems often run on diesel; stationary systems use electricity.

  • Flexibility: Mobile units offer flexibility; stationary units ensure consistency.

Crusher Spare Parts: Purpose, Function, Use Cases

Crusher spare parts are essential for ensuring operational efficiency and minimizing downtime. Common parts include:

  • Jaw plates: Used in jaw crushers for material compression.

  • Mantles and concaves: Used in cone crushers to crush material between moving and fixed surfaces.

  • Hammers and liners: Found in impact crushers, they endure high stress to crush hard materials.

  • Screen meshes: Classify materials based on size.

  • Conveyor rollers and belts: Transport crushed materials.

  • Drive motors and gearboxes: Provide motion and torque to mechanical parts.

  • Vibrating feeders: Ensure a consistent flow of material into the crusher.

These components are widely used in mining, construction recycling, cement production, and infrastructure sectors.
