A crusher is an industrial machine used to break hard materials such as stone, rock, or ore into smaller pieces.

  • Purpose: Converts large stones, ores, or construction debris into smaller, easier-to-handle pieces suitable for transport or further processing.

  • How it works: Feed material enters the crushing chamber via a feeder. It is crushed or impacted by moving or fixed surfaces (jaw, cone, roller, rotor). The output is then screened by vibrating screens.

  • Applications: Used in mining, construction aggregates, infrastructure projects, concrete/asphalt recycling, cement plants, and natural stone processing facilities.

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

A mobile crusher is a portable crushing and screening plant mounted on wheels or tracks.

  • Purpose: Ideal for temporary or remote projects where building a fixed plant isn’t feasible and operational flexibility is needed.

  • How it works: Contains feeder, crusher, screens, conveyors assembled on one mobile chassis. Transported to site, powered by diesel generator or electrical connection.

  • Applications: Temporary worksites, dam/road/bridge construction, quarrying, construction waste recycling, and project-based stone processing.

3. What Is a Stationary Crusher, What Is Its Purpose, How Does It Work, and Where Is It Used?

A stationary crusher is a high-capacity crushing and screening plant installed permanently at a specific location.

  • Purpose: Suitable for continuous, large-scale crushing operations with high throughput.

  • How it works: Comprises feeders, crushers (jaw/cone/roller), vibrating screens, and conveyors integrated on a fixed structure. Automatically controlled and powered by grid electricity.

  • Applications: Large-scale quarries, cement factories, aggregates production, stone and recycling plants.

4. Differences Between Stationary and Mobile Crushers

  • Portability: Stationary is immobile; mobile is transportable.

  • Installation time: Stationary takes longer to install; mobile starts in days.

  • Cost: Stationary requires high upfront investment; mobile is more affordable and flexible.

  • Capacity: Stationary offers higher capacity; mobile suits medium or smaller operations.

  • Operation: Stationary is for continuous, long-term use; mobile is ideal for project-based, short-term operations.

5. What Is a Limestone Crushing‑Screening Plant, What Is Its Purpose, How Does It Work, and Where Is It Used?

A limestone crushing-screening plant processes raw limestone from quarries into various size products.

  • Purpose: Produces dust, granules, or aggregates of different sizes from limestone. These are used in construction, cement, limeworks, agricultural soil treatment, glass and ceramic industries, and chemical sectors.

  • How it works: Limestone is fed into crushers (jaw, cone) via feeders. Crushed material is separated by vibrating screens. Optional secondary crushing or grinding may be used. The plant includes conveyors, screens, crushers, dust suppression systems, and stockpiles.

  • Applications: Construction aggregates, cement/lime additive, soil conditioner in agriculture, raw material for glass/ceramic, filler in chemical and industrial applications.
