A mobile crusher is a portable crushing and screening system designed to reduce large stones, rocks, and construction materials into usable aggregates on-site. Unlike stationary plants, mobile crushers are mounted on trailers, wheels, or tracks, and can be easily relocated between sites. This enables cost savings on transportation and setup time.

How Does a Mobile Crusher Work?

  1. Feeding System: Material is fed through a vibrating feeder into the crusher.

  2. Crushing Unit: Materials are crushed by a jaw, impact, cone, or vertical shaft crusher.

  3. Screening Unit: Crushed material is classified by vibrating screens.

  4. Conveyors: Final products are discharged via conveyor belts.

  5. Recirculation: Oversized material is returned for further crushing.

What is it Used For?

  • Aggregate production

  • Gravel and subbase materials

  • Recycling of demolition waste

  • Primary crushing of ore and rocks

  • Material preparation for concrete/asphalt plants

Application Areas

  • Stone and rock quarries

  • Infrastructure construction (roads, bridges, airports)

  • Urban demolition sites

  • Mobile recycling units

  • Mining operations

What is a Vertical Shaft Mobile Crusher (VSI)?

A Vertical Shaft Mobile Crusher, or VSI, is a mobile plant using high-speed impact crushing via a vertical rotor. It’s ideal for producing fine, cubical-shaped aggregates required in concrete and asphalt.

How Does a VSI Crusher Work?

  1. Material is fed into the high-speed rotor.

  2. The rotor accelerates the material outward using centrifugal force.

  3. The material hits fixed surfaces or a bed of other rocks.

  4. Fragmentation occurs through collision and abrasion.

  5. Screened materials are discharged; oversized particles are recycled.

What Is It Used For?

  • Producing high-quality 0–5 mm sand or fine aggregates

  • Creating cubical-shaped materials ideal for concrete

  • Asphalt applications requiring angular aggregate

  • Replacing stone dust in certain fill applications

  • Working on medium to soft rocks with high efficiency

Application Fields:

  • Concrete plants

  • Asphalt production

  • Sand manufacturing

  • Construction fill

  • Recycled material processing
