A crusher is a machine that reduces large volumes of rock, stone, or ore into smaller, manageable fragments through mechanical methods. It is commonly used in construction and mining industries for producing concrete, asphalt, fill materials, infrastructure applications, and recycling. The process begins with a vibrating feeder that transports material into the machine. Jaw, cone, or impact crushing units then reduce the material to the desired size. Crushed particles are passed through vibrating screens to sort by size. Suitable particles are separated while oversized fragments return to the crusher to be reprocessed. The final result is a uniform aggregate.

A mobile crusher is a portable crushing and screening system mounted on wheels or tracks. It processes material on-site without the need for transportation. Powered by diesel or electricity, it is used in roadworks, construction sites, temporary mine operations, recycling plants, and disaster response areas. Mobile crushers offer fast deployment, flexibility, and on-site processing, but have lower capacity compared to stationary systems.

A stationary crusher is a permanent, high-capacity crushing and screening plant installed on concrete or steel foundations. It is used in large quarries, mining operations, concrete and asphalt plants, port fill jobs, dam and infrastructure construction. Raw material is loaded from bunkers or silos, processed first in primary crushers, then in secondary units. Vibrating screens sort material by size, and conveyors move suitable product to storage or dispatch. PLC and automation systems ensure continuous, efficient production.

The key differences between stationary and mobile crushers are: mobile units are portable, fast to set up, require minimal infrastructure, and are suited for short-term projects, but have limited capacity. Stationary units are fixed, offer high capacity and continuous production, but involve longer installation, more infrastructure, and higher investment.

A mobile sand washing and screening plant is an integrated system that washes and classifies natural sand and gravel without crushing. Usually deployed on portable equipment at site, the system includes a vibrating feeder, wash drum or bucket, screening unit, and water recycling equipment. Material is fed, washed to remove dust, clay, and impurities, then classified through vibrating screens into different fractions. Cleaned sand is collected via conveyors for storage. Water is treated and reused to reduce consumption. These plants are used in concrete and mortar production, landscape work, drainage systems, filter media, landfill cover layers, and infrastructure projects.
