A crusher is a heavy-duty industrial machine that reduces large rocks, stones, or mineral ores into smaller pieces. Material is fed into a feeder and passed through jaw, cone, or impact mechanisms that apply compressive or impact force. The resulting products are classified using vibrating screens and directed via conveyors to storage. Crushers are essential in construction for producing aggregates used in concrete and asphalt, infrastructure and road projects, mining for ore processing, rock quarries, and recycling plants.

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

A mobile crusher is a movable crushing and screening plant built on a wheeled or tracked carrier. Powered by diesel or electricity, it integrates feeder hoppers, primary and secondary crushers, screens, and conveyors in a single unit. It can be quickly deployed to process material directly on site, delivering sized aggregates before transportation. It is commonly used in small-to-mid scale mining operations, road and infrastructure maintenance works, urban demolition and redevelopment projects, quarry on-site crushing, and recycling sites.

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

A fixed crusher is a permanent, high-volume crushing and screening plant. Material is delivered by truck or conveyor, crushed initially by a jaw crusher, then further reduced by cone or impact crushers. Vibrating screen decks classify the products which are then conveyed to storage. Fixed crushers are used in continuous high-capacity applications such as dam, highway, port, airport construction, and large concrete/asphalt plant operations.

What Are the Differences Between Fixed and Mobile Crushers?

Fixed crushers are stationary, designed for high-throughput, continuous operations, but have long setup times and cannot be relocated. Mobile crushers are portable, deployable quickly, and flexible across sites, though they have limited capacity relative to fixed units. Suitable for short-term or multi-site jobs, mobile crushers offer cost-effective initial investment; fixed units are more efficient for long-term, large-scale production needs.

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

A cone crusher uses a rotating mantle within a fixed concave surface to compress material in a conical chamber. Material is fed from the top; crushing occurs as the mantle gyrates within the concave, and crushed material exits through the bottom. Output size is regulated by spring or hydraulic systems. Cone crushers are typically used for secondary and tertiary crushing stages. They produce uniform aggregates from hard rocks like granite and limestone, ores, and recycled asphalt. With robust structural design, cone crushers deliver reliable performance with minimal maintenance.
