A crusher is a comprehensive crushing-screening system designed to reduce large and bulky materials such as stone, rubble or rock into smaller, more manageable forms. It integrates feed mechanisms, crushers, screening units and conveyor systems to convert raw material into usable output. The process begins by feeding raw material into a bunker or vibrating feeder. A primary crusher—usually a jaw or impact crusher—performs coarse reduction under high pressure. Secondary crushers, such as cone or impact types, further reduce material size. Finally, vibrating screens separate the material into different aggregate grades. Belt conveyors then direct materials to storage or mix facilities. Crushers play a central role in aggregate supply for concrete plants, asphalt operations, road, bridge, dam infrastructure, quarry extraction, ore preparation, demolition debris recycling, and overall construction material supply.

What Is a Mobile Crusher? What Does It Do? How Does It Work? Where Is It Employed?

A mobile crusher is a transportable crushing-screening system mounted on wheeled or tracked chassis, engineered for rapid deployment. Upon arrival at the site, it is stabilized by hydraulic outriggers and powered by diesel generators or an electrical power connection. Within the plant, jaw, cone or impact crushers break down the material, vibrating screens separate it, and conveyors remove the finished product. The system can operate in both closed circuit and open circuit configurations. Mobile crushers are ideal for remote or rugged terrain jobs, mining site preparation, highway and utility works, urban demolition, and recycling operations due to their mobility, agility, and setup efficiency.

What Is a Stationary Crusher? Purpose, Operation, Use Cases

A stationary crusher is a permanent crushing-screening plant built for long-term high-capacity operation. Raw material is fed via bunker or hopper systems and undergoes primary crushing in jaw or impact crushers. Secondary crushing with cone or multi-cylinder crushers follows. The vibrating screen classifies materials, and conveyor networks distribute aggregates to various storage zones or direct processing lines. Stationary plants are heavily deployed in quarry operations, road, airport or dam construction, and major urban concrete and asphalt facilities. These systems incorporate advanced automation, dust suppression, feeding and transfer systems, and washing modules to meet environmental standards and high throughput demands.

Differences Between Stationary and Mobile Crushers

Stationary crushers feature permanent installation, high capacity, advanced automation and integrated environmental control but incur higher upfront investment and require infrastructure support. Mobile crushers offer swift setup, transportability, low initial costs, and flexibility; their throughput is lower and environmental systems are modular. Mobile crushers are suited for temporary, multi-site, or rapidly evolving projects, while stationary crushers excel in continuous large-scale operations.

What Is a Gravel Crushing–Screening Plant? Purpose, Operation, Applications

A gravel crushing-screening plant processes natural or riverbed gravel, refining it to low-dust, precisely graded aggregates. Initial coarse crushing by a jaw crusher reduces raw gravel size. Subsequent cone or impact crushers achieve fine granularity. Vibrating screens produce graded fractions such as 4 mm, 8 mm, 16 mm or 32 mm. Integrated washing systems eliminate silt and fines, and magnetic separators remove metal contaminants. Final products serve as concrete aggregate, paving stone substrate, decorative landscaping material, and drainage bed fill. Gravel aggregates are essential in road bases, architectural landscapes, water system infrastructure, and decorative ground cover due to their aesthetic and functional qualities.
