A crusher is a heavy-duty industrial machine that breaks down large, hard, and irregular materials into smaller pieces. Commonly used to process stones, rocks, ores, crushed concrete, and asphalt into manageable sizes. It plays a critical role in construction, mining, recycling, roadwork, and dam building.

The working principle is mechanical: material enters via a feeder, then passes through crushing units such as jaw, cone, or impact crushers. The crushed material is then screened and sorted by size, and finally conveyed to stockpiles. This process yields aggregates of specific sizes.

A mobile crusher is a portable crushing and screening system integrated on wheels or tracks, enabling on-site operation without permanent plant infrastructure. Its main advantages include rapid deployment, flexibility, minimal infrastructure, and reduced transport costs.

Raw material is loaded into the feeder via a loader, crushed in the primary unit, screened for size, and directly stockpiled on-site. It is heavily used in road, bridge, tunnel construction, recycling sites, and quarries where mobility is critical.

3. What Is a Stationary Crusher, What Is It Used For, How Does It Work and Where Is It Used?

A stationary crusher is a high-capacity, permanently installed crushing system suited for long-term operations in mines, industrial facilities, and manufacturing plants.

Material is delivered by trucks or conveyors, goes through primary, secondary, and possibly tertiary crushing stages, is screened, and then transported to stock areas. Designed for continuous, large-scale production.

4. What Are the Differences Between Stationary and Mobile Crushers?

  • Mobility and deployment: Mobile crushers allow quick setup and relocation; stationary systems demand heavy infrastructure.

  • Capacity: Stationary crushers have greater throughput; mobile units are suited for medium-scale applications.

  • Cost and flexibility: Mobile units deliver affordability and on-site adaptability; stationary systems offer lower cost per ton but require large initial investment.

  • Use cases: Mobile is ideal for projects requiring frequent site changes; stationary is used for long-term, large-scale aggregate production.

5. What Is a Jaw Crusher, What Does It Do, How Does It Work and Where Is It Used?

A jaw crusher operates by crushing materials between a fixed and a moving jaw. It is ideal for breaking down large rock and ore blocks into smaller pieces for further processing.

Its primary function is to take oversized materials and reduce them to below a certain size, adjustable as needed. It can reduce material to several centimeters depending on model and settings.

Operation steps: material enters the feeder, the moving jaw compresses it against the fixed jaw, fractures the rock, and reduced material exits through the bottom.

Jaw crushers are widely used in quarries, mining, construction, recycling, and road base production. They serve as primary crushers in crushing circuits, preparing material for secondary crushing or direct use.
