A crusher is an industrial machine that breaks down large, hard materials like rock, stone, and ore into smaller, processable particles. It is essential for providing aggregates used in construction materials. Material enters through a vibrating feeder, is crushed in jaw, cone, or impact units, and then classified by vibrating screens. Oversized pieces are returned to the crusher for reprocessing. Crushers are heavily used in concrete and asphalt plants, road and bridge construction, quarries, mining sites, and recycling centers.

A mobile crusher is a transportable crushing and screening unit mounted on wheels or tracks. It processes material directly at the site, reducing transportation costs and enabling rapid setup. Material fed into the unit is crushed, screened, and conveyed to storage or stockpiles. Powered by diesel or electricity, mobile units are ideal for construction sites, road projects, recycling operations, temporary mining areas, and emergency setups.

A stationary crusher is a fixed, high-capacity crushing and screening plant installed on concrete or steel foundations. Raw material is loaded via bunkers or silos, initially crushed by a jaw crusher, further refined in cone or impact units, and sized by vibrating screens. Suitable material is conveyed to storage. PLC-driven automation allows continuous, around-the-clock production. Stationary units are favored in large quarries, mining operations, concrete and asphalt plants, port fill projects, and large infrastructure builds.

The main differences between stationary and mobile crushers lie in portability, setup time, production capacity, and infrastructure requirements. Mobile crushers are portable, fast to deploy, with minimal infrastructure, but have moderate capacity. Stationary crushers are fixed installations with higher capacity and continuous production, but require substantial investment and infrastructure.

A quartz crushing and screening plant is an integrated facility that crushes natural quartz into specified size fractions for industrial use. Quartz is a critical raw material for glass, electronics, ceramics, silicone products, printing inks, toothpaste, and chemical industries. Initially, coarse crushing is performed in jaw crushers. Material is then further processed in cone or impact crushers, followed by size classification with vibrating screens. Optional grinding can produce micronized quartz. The resulting fractions are conveyed for packaging or storage.
