A crusher is an integrated crushing-screening system that processes hard materials like rock, stone, concrete, asphalt, or ore into smaller, usable sizes. It consists of a feeder hopper, primary crusher (jaw or impact), secondary crusher (cone or other type), vibrating screens, belt conveyors, and a control unit.
Material is fed into the hopper. The primary crusher performs coarse crushing. Secondary crushers refine the product into smaller sizes. Vibrating screens classify the material, and conveyors transport the output to storage or shipment areas.
Crushers find applications in quarries, mining operations, construction projects (road, bridge, tunnel, dam), concrete and asphalt plants, recycling sites, railway ballast production, infrastructure development, and industrial mineral processing.

What is a mobile crusher, what is it used for, how does it work, and where is it used?

A mobile crusher is a portable crushing-screening system mounted on wheels or tracks, designed for on-site material processing. Particularly beneficial for temporary or remote sites, it allows rapid setup.
Powered by electric supply or diesel generator, it integrates a feeder hopper, primary and secondary crushers, vibrating screens, and conveyors. It conducts continuous feeding, crushing, screening, and delivery of materials and can be ready for operation in hours.
Used in road, bridge and tunnel works, urban demolition zones, concrete/asphalt recycling facilities, temporary mining sites, and remote or challenging terrain projects.

What is a stationary crusher, what is it used for, how does it work, and where is it used?

A stationary crusher is a high-capacity crushing-screening plant permanently installed on a concrete foundation for prolonged use.
Material loading starts in the feeder. A primary crusher handles coarse crushing; secondary crushers refine the product; vibrating screens classify it; conveyors deliver it to storage or dispatch. These systems often employ automation and can handle high daily tonnage.
They are commonly used in large quarries, mining sites, concrete and cement plants, infrastructure projects, and industrial mineral processing facilities.

Differences between stationary and mobile crushers

  • Mobility: Mobile units are portable; stationary units are fixed.

  • Setup time: Mobile systems can start within hours; stationary plants require weeks to install.

  • Capacity: Stationary systems support high-volume production; mobile systems operate at mid-range capacity.

  • Flexibility: Mobile units can move across various project sites; stationary systems are optimized for long-term, consistent production.

  • Cost: Mobile systems have lower initial investment; stationary systems demand higher capital but offer efficient long-term operation.

  • Use case: Mobile crushers suit temporary, on-site operations; stationary crushers are built for large-scale, continuous production.

What is a crushing-screening plant, what is it used for, how does it work, and where is it used?

A crushing-screening plant comprises a systematic assembly of feeders, crushers (primary and secondary), vibrating screens, conveyors, dust control units, and sometimes washing/classification modules. The plant processes materials like natural rock, ore, concrete or asphalt debris into aggregates, ballast, fill, or industrial feedstock.
The workflow involves feeding, crushing, dimension sorting, dust suppression, conveyance, and storage or shipment.
These plants are highly versatile and are utilized in quarries, mining operations, concrete/asphalt plants, recycling facilities, road and rail construction, dam building, urban infrastructure projects, and industries requiring processed minerals (ceramics, glass, chemicals, agriculture, etc.).
