A crusher is a heavy machinery used to break down large, hard materials such as stone, rock, concrete, or ore into smaller, workable sizes. Key industries include mining, quarrying, construction, road building, and recycling. Crushers use mechanisms like jaw, impact, or cone crushers. Material is loaded into a hopper, crushed under mechanical forces, and then sent through screens to separate different fractions. The resulting aggregate is used in construction materials, including concrete, asphalt, or filling.

2. What is a mobile crusher, what does it do, how does it work, and where is it used?

A mobile crusher is a portable crushing system mounted on wheels or tracks. It is powered by diesel or generator and designed for fast deployment across different sites. Material is fed into the hopper and broken down by the crusher unit. The crushed material is then separated into various size fractions via vibrating screens. Mobile crushers are ideal for temporary sites, road repairs, construction debris recycling, on-site crushing, and mobile mining. They provide flexibility and quick setup.

3. What is a fixed crusher, what does it do, how does it work, and where is it used?

A fixed crusher is a permanently installed high-capacity crushing system, typically electrically powered and often automated. Feeder systems continuously supply material to jaw, cone, or impact crushers. Crushed material is then sized via screens, and optionally washed or dried, before storage. Fixed crushers are used in large-scale quarrying, mining, concrete and asphalt production, dam and infrastructure projects. They offer continuous, efficient, high-output crushing.

4. What are the differences between fixed and mobile crushers?

  • Mobility: Fixed crushers are stationary; mobile crushers can be relocated.

  • Installation time: Fixed systems require longer setup and infrastructure; mobile systems install quickly.

  • Capacity: Fixed crushers handle higher volumes; mobile units are for medium scale operations.

  • Power source: Fixed plants use electricity; mobile units are diesel/generator powered.

  • Maintenance: Fixed systems have fewer moving parts and lower maintenance; mobile units need more frequent service but provide operational flexibility.

5. What is an aggregate crushing and screening plant, what does it do, how does it work, and where is it used?

An aggregate crushing and screening plant processes stone, rock, or concrete by crushing and then screening to produce graded aggregates. The plant includes crushers (jaw, cone, impact), feeders, vibrating screens, and conveyor systems. Materials are crushed, classified by size, and optionally washed. Produced aggregates are used in concrete, asphalt, road construction, building fill layers, civil projects, cement production, and landscaping. These plants ensure structural quality and supply project-ready materials.
