A crusher is an industrial crushing‑screening machine that breaks down large stones, rocks, concrete, or rubble into smaller usable pieces and then classifies them by size. Raw material is loaded into a bunker or vibrating feeder. A primary crusher such as a jaw or impact crusher performs initial coarse crushing. Then secondary crushers like cone or impact crushers refine the pieces to the desired size. A vibrating screen separates the material into different fractions. The sorted output is conveyed to storage areas or trucks. Crushers are widely used for aggregate production in roads, bridges, dams, concrete and asphalt plants, quarry and mining ore preparation, and for recycling demolition waste.

What Is a Mobile Crusher, Its Function, How It Works, and Where It Is Used

A mobile crusher is a portable crushing‑screening system mounted on a wheeled or tracked chassis. It is transported to the site, stabilized quickly with hydraulic jacks, and powered using electricity or a diesel generator. Inside the unit, jaw, cone, or impact crushers break the material while vibrating screens classify it. The output is carried away by conveyor belts. Mobile crushers are particularly useful in remote, mountainous, or temporary construction sites and infrastructure projects as well as demolition waste processing due to their flexibility and ease of deployment.

What Is a Stationary Crusher, Its Function, How It Works, and Where It Is Used

A stationary crusher is a fixed, high‑capacity crushing‑screening plant that requires permanent installation. These systems are commonly used in quarries, large concrete and asphalt plants, highways, bridges, and dam construction. Material is fed via a bunker or vibrating feeder, crushed by primary crushers, refined by secondary crushers, classified by vibrating screens, and transported via conveyors. Stationary plants often include automation, dust suppression, and washing systems for environmental and efficiency benefits.

Differences Between Stationary and Mobile Crushers

Stationary crushers are permanent installations capable of processing high volumes and offering full automation and integrated controls. They require more time and infrastructure for setup but are more cost‑effective over time. Mobile crushers offer portability, quick setup, and flexibility but operate at lower capacity. Mobile systems are ideal for short‑term or variable job sites, while stationary systems serve long‑term, large‑scale production. Dust suppression and washing are built‑in for stationary plants, whereas mobile plants use modular attachments.

What Is a Gravel Crushing‑Screening Plant, Its Function, How It Works, and Where It Is Used

A gravel crushing‑screening plant processes gravel collected from natural deposits or riverbeds by crushing and sorting it into size‑specified aggregates. Raw gravel is loaded into a bunker or feeder and initially crushed using jaw crushers. It is then further reduced using cone or impact crushers. Vibrating screens separate the material into fractions. The resulting gravel is used in paving, concrete and asphalt mixes, landscaping, and drainage applications. Optional washing units can remove dirt and silt while magnetic separators eliminate metal contaminants. Gravel aggregates are extensively employed in infrastructure construction, waterway systems, architectural landscaping, and drainage projects.
