A crusher is a heavy-duty industrial machine used to break down hard materials such as stone, rock, ore, or concrete into smaller, usable fragments. Crushers are widely used in mining, quarrying, road construction, and recycling industries.

Crushers work using jaw, impact, or cone mechanisms. Material is fed into the machine and broken down by mechanical force. After crushing, it is classified by size using screening systems.

Application areas:

  • Aggregate production in quarries

  • Road and highway construction

  • Concrete and asphalt production

  • Recycling of construction waste

  • Ore processing in mining operations

2. 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 unit mounted on wheels or tracks. It can be easily moved from one site to another, making it ideal for temporary or remote projects.

It works like a stationary crusher, but it is powered by a diesel engine or generator. Material is loaded into the mobile unit and crushed. Then it is screened into different sizes and used directly on-site.

Application areas:

  • Temporary construction sites

  • Road rehabilitation

  • Recycling of demolition materials

  • On-site crushing projects

  • Mobile mining operations

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

A fixed crusher is installed permanently at a specific location and is designed for high-capacity crushing operations. It is used in long-term projects such as large quarries, cement plants, and mining operations.

Material is fed into the plant using feeders. It is then crushed and sorted by screens. Optional washing systems may be included. These plants run on electricity and are often controlled by automated systems.

Application areas:

  • Large-scale quarry operations

  • Cement and asphalt production

  • Pre-processing of ores

  • Infrastructure and dam construction

  • Continuous aggregate production

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

  • Location: Fixed crushers are permanent; mobile crushers are portable.

  • Installation time: Fixed crushers take longer to install; mobile units are quicker.

  • Mobility: Mobile crushers can move between sites; fixed ones cannot.

  • Power source: Fixed plants use electricity; mobile units run on diesel.

  • Capacity: Fixed crushers offer higher output; mobile units have moderate capacity.

  • Maintenance: Fixed systems are simpler and require less frequent maintenance.

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

A crushing and screening plant is a complete facility that breaks down and separates materials like rock and ore. It integrates crushers, screens, conveyors, and sometimes washing units.

The material is first crushed, then passed through vibrating screens for size classification. If necessary, it is washed or dried. All operations are continuous and automated.

Application areas:

  • Aggregate production

  • Concrete and asphalt raw material preparation

  • Ore processing before enrichment

  • Waste recycling

  • Infrastructure and large construction projects
