A crusher is an industrial system that mechanically reduces large volumes of stone, rock, and debris into smaller, usable fragments, and then classifies these fragments using vibrating screens to obtain different size fractions. This process comprises stages of feeding, crushing, and sizing. Initially, raw material is delivered to the feeding hopper. A primary crusher, such as a jaw type, performs coarse crushing. Subsequently, cone or impact crushers refine the material to more precise particle sizes. Vibrating screens separate the material into various fractions, which are then conveyed for storage or further use. Crushers are essential for producing aggregates for roads, bridges, dams, and buildings, supplying raw materials for concrete and asphalt plants, operating within quarries, and recycling demolition waste.

What Is a Mobile Crusher? Its Purpose, Operation, and Applications

A mobile crusher is a portable crushing and screening unit mounted on wheels or tracks designed for swift deployment. It is transported to the site by truck, stabilized with hydraulic jacks, connected to an energy source, and quickly made operational. Crushers—jaw, cone, or impact types—reduce material size, and vibrating screens perform classification. Conveyor belts remove the finished product. Mobile crushers are especially useful in remote or hard-to-reach locations, temporary construction sites, pre-mining operations, on-site demolition waste processing, and road and infrastructure projects due to their rapid setup and transportability.

What Is a Stationary Crusher? Its Purpose, Operation, and Applications

A stationary crusher is a permanent, high-capacity production facility integrated into fixed infrastructure. Raw material is fed through a bunker or vibrating feeder. A primary crusher reduces the largest fragments, followed by cone or impact crushers for finer reduction. Vibrating screens classify the sized material, and conveyor belts deliver the sorted outputs for storage or dispatch. This type of facility is commonly used in large-scale quarry operations, fixed concrete and asphalt plants, highway, bridge, and dam construction, and long-term infrastructure development. Stationary crushers offer extensive automation, environmental control (such as dust suppression and washing systems), and higher throughput, making them more efficient over prolonged operations.

Differences Between Stationary and Mobile Crushers

Stationary crushers are built for permanency, require comprehensive infrastructure, and support greater production volumes. They offer robust automation and environmental management. Mobile crushers, on the other hand, offer agility and rapid setup but have limited throughput. They are ideal for short-term or multi-site projects and are more flexible but lack the scale and control systems of stationary installations.
