A mobile crusher is a portable crushing and screening plant that can process hard materials such as stone, rock, ore, and construction debris directly on-site. It is usually mounted on wheels or tracks and includes all necessary equipment such as feeders, crushers, screens, and conveyors on a single chassis.

What Does It Do?

It crushes raw material into smaller, processable sizes to be used in construction, road building, infrastructure, and mining. It eliminates the need to transport materials to a fixed crushing plant.

How Does It Work?

  • Material is fed into the hopper or feeder.

  • The primary crusher (jaw, impact, or cone) crushes the material.

  • A vibrating screen classifies the output into various sizes.

  • Conveyor belts transfer the finished material to the storage area.

  • If needed, secondary crushing is applied for finer sizes.

Where Is It Used?

  • Temporary construction sites

  • Road repair and maintenance

  • Mountainous or hard-to-reach areas

  • Recycling and demolition projects

  • Infrastructure developments like dams and bridges

 What is a Crusher, What Does It Do, How Does It Work, and Where Is It Used?

A crusher is an industrial machine used to reduce the size of large stones, rocks, minerals, or concrete materials. It’s an essential part of the material processing chain in construction and mining industries.

What Does It Do?

It processes raw materials into smaller, uniform sizes suitable for further processing or direct use in construction.

How Does It Work?

  • Raw material is fed into the crusher.

  • The crushing unit (jaw, cone, impact, vertical shaft) reduces the size.

  • The material is then screened through vibrating screens.

  • Conveyors transport the classified material to stockpiles.

Where Is It Used?

  • Stone quarries

  • Road and highway construction

  • Ready-mix concrete plants

  • Recycling facilities

  • Mining and mineral processing operations

 What Are Mobile and Fixed Crushers? What Are the Differences? Where Are They Commonly Used?

Mobile Crusher:

Portable units that can be moved to different project sites and quickly installed for material processing.

Fixed Crusher:

Installed permanently at one location, ideal for continuous and high-capacity production.

What is a Granite Crushing and Screening Plant, What Does It Do, How Does It Work, and Where Is It Used?

A granite crushing and screening plant is a specialized industrial facility designed to break down and classify granite—a hard, durable, igneous rock—into different usable sizes.

What Does It Do?

It processes granite into various sizes for construction, paving, landscaping, and heavy-load infrastructure projects.

How Does It Work?

  • Large granite blocks are delivered to the facility.

  • A jaw crusher performs the primary crushing.

  • Secondary crushing is done with cone or impact crushers.

  • Vibrating screens separate the output into fractions.

  • Final products are used in different sectors based on size and shape.

Where Is It Used?

  • Road and rail infrastructure

  • Concrete and asphalt production

  • Construction and building materials

  • Landscaping and decorative stone

  • Coastal and port reinforcement projects
