A crusher is a heavy-duty machine designed to reduce large rocks, stones, or ore into smaller pieces for practical use. It produces aggregate necessary for building materials. Material fed into the crusher through a feeder is shredded through jaw, cone, or impact mechanisms under high mechanical force. The crushed product is sized by vibrating screens and then conveyed to storage. Crushers are widely used in concrete and asphalt production, road and bridge construction, dam projects, mining, quarries, and recycling plants.

2. What Is a Mobile Crusher, What Does It Do, How Does It Work, and Where Is It Used?

A mobile crusher is a transportable crushing and screening plant mounted on wheels or tracks. Powered by diesel or electricity, it combines feeders, primary and secondary crushers, screening units, and conveyors into a single compact system. It can operate directly on site, crushing and sizing material without the need for intermediate transportation. It is ideal for applications like mining, construction projects, road maintenance, urban redevelopment, and recycling facilities that require flexibility and quick deployment.

3. What Is a Fixed Crusher, What Does It Do, How Does It Work, and Where Is It Used?

A fixed crusher is a permanent, high-throughput crushing and screening plant. Material is delivered by trucks or conveyors, crushed using jaw, cone, or impact crushers, then sized through vibrating screens. Finished aggregates are conveyed to storage. Fixed crushers are suited for large-scale, continuous production in dam, highway, and port projects, as well as in concrete and asphalt plants and major construction sites.

4. What Are the Differences Between Fixed and Mobile Crushers?

  • Transportability: Mobile units are portable; fixed units remain in place.

  • Setup Time: Mobile crushers can be operational within minutes; fixed plants require installation and commissioning.

  • Capacity: Fixed plants can handle large volume; mobile units deliver moderate output.

  • Flexibility: Mobile plants can move across sites; fixed ones operate at a single location.

  • Cost: Mobile systems may require higher initial investment but offer logistical advantages; fixed systems are cost-effective for long-term, high-volume production.

5. What Is an Aggregate Washing and Screening Plant, What Does It Do, How Does It Work, and Where Is It Used?

An aggregate washing and screening plant cleans crushed stone, sand, and gravel by removing fines such as dust, clay, and silt. The process includes water washing combined with vibrating screens for size classification. The clean, separated aggregate fractions are used for concrete, asphalt, mortar production, infrastructure backfill, prefabricated structures, and landscaping. The plant typically includes washing chambers, screen decks, conveyors, and water recycling systems.
