A crusher is an industrial crushing-screening system designed to mechanically break down large rocks, stone, concrete, or rubble into smaller fragments and then classify them by size. The operation sequence involves feeding material into a hopper or vibrating feeder, coarse crushing with a primary crusher (jaw, impact or cone), further sizing with secondary or tertiary crushers, separation via vibrating screens, and product conveyance. These systems are extensively used in infrastructure projects like roads, bridges, dams, concrete and asphalt plants, quarry operations, mining preparation, and demolition waste recycling.

What Is a Mobile Crusher, What Does It Do, How Does It Work and Where Is It Used

A mobile crusher is a portable crushing-screening unit mounted on a wheeled or tracked chassis. Once on site, it is stabilized using hydraulic legs and powered via electricity or diesel. Crushers in the unit reduce material size, vibrating screens classify particle sizes, and conveyors transport the output. Mobile crushers are ideal for remote or temporary sites, construction and demolition zones, mining pre-processing, and fast-paced infrastructure needs due to their mobility, quick setup, and cost efficiency.

What Is a Stationary Crusher, What Does It Do, How Does It Work and Where Is It Used

A stationary crusher is a fixed crushing-screening plant with permanent infrastructure and high throughput. Raw material enters via bunkers or feeders, undergoes primary crushing, finer secondary or tertiary crushing, vibrating screening, and final product conveying. Stationary crushers are used in quarries, concrete/asphalt facilities, highways, bridges, dam projects, and mining sites. Equipped with automation, dust suppression and washing systems, they ensure operational efficiency and environmental compliance.

Differences Between Stationary and Mobile Crushers

Stationary crushers offer high capacity, full automation, robust infrastructure and environmental control. They require longer setup and higher investment but deliver lower unit costs over time. Mobile crushers provide quick deployment, flexibility and lower upfront costs but have lower capacity and limited automation. Mobile units are suited for temporary or multi-site operations, while stationary systems handle continuous, large-scale production.

What Is a Closed‑Circuit Crushing–Screening Plant, What Does It Do, How Does It Work and Where Is It Used

A closed‑circuit crushing–screening plant continuously circulates material between the crusher and screen until the desired particle size is achieved. After initial crushing, material passes through a screen; undersize is conveyed, oversized returns to the crusher. This loop ensures precise size control, higher product quality, and minimized waste. Closed‑circuit systems are essential for producing concrete and asphalt aggregates, recovering valuable minerals, and demanding infrastructure applications. They can be installed in either stationary or mobile configurations and incorporate automation, monitoring, dust-water control systems for efficient and environmentally friendly operation.
