A crusher (or gyratory/jaw/cone crusher) is a mechanical machine used to reduce large rocks, ores, construction debris into smaller, more manageable pieces.

  • Purpose
    It breaks down oversized material into smaller, uniform particles for easier transportation, storage, grinding, or further processing.

  • How it works
    Feed material enters a crushing chamber. Inside, rotating or stationary crushing surfaces (jaw plates, cones, rolls, or high-speed rotors with stationary anvils) compress and fracture the material until it passes through the outlet opening.

  • Applications
    Mining (coal, iron ore, gold, copper, etc.), construction (aggregate production), recycling (concrete, asphalt), stone/quarry operations, cement plants, infrastructure projects.

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

A mobile crusher is a portable crushing plant mounted on wheels or tracks, which can be moved between sites conveniently.

  • Purpose
    Ideal for projects in remote or temporary locations, reducing logistics by moving crushing equipment closer to excavations.

  • How it works
    Feeding unit, crusher, screens, and conveyors are all assembled on a chassis. Powered by diesel engines or generators, it is driven to the jobsite, set up, and connected to fuel or electricity.

  • Applications
    Road, bridge, dam construction sites, demolition and excavation waste, quarries, project-based mining, recycling at various locations.

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

A stationary crusher is a permanent crushing facility installed in a fixed location for long-term operations.

  • Purpose
    Designed for high-capacity, continuous crushing missions.

  • How it works
    Includes fixed structures: feeders, crushers (jaw, cone, gyratory), vibrating screens, conveyors, stockpiles. It runs off mains electricity and is controlled centrally.

  • Applications
    Large mining operations, cement plants, rock and marble quarries, aggregate production with consistent, high throughput.

4. Differences between stationary and mobile crushers

  • Installation: Stationary is permanent; mobile is quick to deploy and relocate.

  • Portability: Stationary fixed; mobile easily transports.

  • Capacity: Stationary often larger scale; mobile is smaller but flexible.

  • Cost: Stationary has higher capital outlay; mobile has lower initial cost but additional logistics.

  • Flexibility: Mobile suits temporary projects; stationary suits continuous production.

  • Power source: Stationary uses grid power; mobile often diesel or generator.

5. What is a marble crushing-screening plant, what does it do, how does it work, where is it used?

A marble crushing-screening plant processes raw marble blocks from quarries into crushed marble, powders, and granules.

  • Purpose
    Produces lower-value by-products like sand, filler, dust, chips, which are used in construction, ceramics, landscaping, feed additives, etc.

  • How it works
    Blocks are fed into crushers (jaw or cone), then passed through vibrating screens to sort by size. Some products may undergo additional crushing or milling. The line comprises crushers, screens, conveyors, dust separators, and stockpiling bins.

  • Applications
    Construction aggregates, landscaping stone, ceramic fillers, cement additives, soil amendment, feedstock, white chemical products, fillers in various industries.
