A crusher is an industrial machine used to break hard materials such as rock, stone, and ore into smaller, usable pieces. Material is fed into the crusher via a feeder and processed by jaw, cone, or impact crushes until it reaches the desired size. Crushed output is sorted through vibrating screens; oversized particles return for further crushing. Crushers prepare materials for construction, road building, concrete and asphalt production, quarry operations, mining, and recycling applications.

A mobile crusher is a portable unit mounted on wheels or tracks that integrates crushing and screening systems. Powered by fuel or electricity, it processes materials directly on-site, reducing transportation costs and time. Its rapid setup makes it ideal for construction sites, roadworks, recycling yards, temporary mining operations, and disaster response scenarios.

A stationary crusher is permanently installed on concrete or steel foundations and designed for continuous, high-volume production. Raw material is loaded into a feeder, goes through primary and secondary crushing stages, and is then sized via vibrating screens. Conveyors move the classified material to storage. Stationary crushers are used in large quarries, mining operations, concrete and asphalt plants, and infrastructure projects.

The key differences between stationary and mobile crushers lie in setup time, portability, capacity, and infrastructure requirements. Mobile crushers offer fast deployment, high mobility, and minimal infrastructure needs, though their capacity is limited. Stationary crushers provide high capacity and continuous output but require infrastructure investment and are fixed in one place.

A gypsum crushing and screening plant is an integrated system that reduces natural gypsum into suitable sizes for manufacturing materials such as plaster, drywall, and stucco. It starts with jaw crushing, continues with secondary crushing for finer fractions, and uses vibrating screens to classify into predetermined sizes. Optional grinding can produce micronized gypsum. Final products are conveyed to storage or packaging. These materials are then used in construction for drywall, plaster, decorative finishes, in cement as additives, and in agricultural or chemical applications.
