A crusher is a heavy-duty industrial machine designed to reduce large rocks, stones, or ores into smaller, manageable pieces. Material is fed into the machine, where jaw, cone, or impact mechanisms apply mechanical force to break it down. The crushed output is then classified by vibrating screens and conveyed to stockpiled areas. Crushers are widely used to produce aggregates for concrete and asphalt, for infrastructure projects including roads, bridges, tunnels, dam and port construction, in mining for ore preparation, and in 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 portable crushing and screening plant mounted on a wheeled or tracked chassis. Powered by a diesel or electric engine, the system integrates feeding hoppers, primary and secondary crushers, screening units, and conveyors into a single machine. It can be quickly deployed on site to process material directly and then easily relocated. Mobile crushers are ideal for quarry sites, construction projects, road and railway maintenance, urban revitalization sites, and demolition recycling projects due to their operational flexibility.

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

A fixed crusher is a permanently installed, high-capacity crushing and screening plant. Material delivered by trucks or conveyors undergoes primary crushing in a jaw crusher, followed by further size reduction in cone or impact crushers. Vibrating screens classify the material, and conveyors transport it to storage. Fixed crushers support continuous production in large-scale projects such as dam, highway, port, and airport construction, as well as concrete and asphalt plants.

What Are the Differences Between Fixed and Mobile Crushers?

  • Mobility: Mobile crushers can be moved between sites, while fixed crushers remain stationary.

  • Setup Time: Mobile crushers can be operational in minutes; fixed installations can take days or weeks to assemble.

  • Capacity: Fixed systems handle higher volumes; mobile systems are better suited for medium-capacity work.

  • Flexibility: Mobile systems can be redeployed across various sites; fixed systems usually serve long-term, single-site projects.

  • Cost: Mobile crushers reduce transportation costs and offer flexibility but have higher upfront costs; fixed crushers are more cost-effective for large, long-term operations.

What Is a Mobile Stone and Ore Crushing & Screening Plant, What Does It Do, How Does It Work, and Where Is It Used?

A mobile stone and ore crushing & screening plant is a transportable system that processes raw ore or stone blocks at quarry or mine sites into usable size fractions. Material is fed into a feeder, crushed initially in a jaw crusher, then refined in cone or impact crushers. Vibrating screens sort the product into size fractions. The entire process—from feeding and crushing to screening and stockpiling—is integrated, delivering time and cost savings. Applications include construction, road and dam building, mining, railway and highway maintenance, demolition recycling, and production of concrete, asphalt, or prefabricated materials.
