A mobile crusher is a compact and transportable crushing and screening system designed to process hard materials such as rocks, concrete, asphalt, or construction debris on-site. Mounted on wheeled or tracked chassis, it can be deployed rapidly at multiple job sites without needing permanent infrastructure.

A standard mobile crushing unit includes a feed hopper, crusher unit (jaw, cone, or impact type), screening module, and conveyor belts. The process begins when raw material is dumped into the hopper, passed through the crusher for size reduction, classified by the screen, and transported to storage by conveyors. Mobile crushers may also feature integrated generator systems, making them suitable for remote locations.

Main applications: Road construction, demolition recycling, mining, infrastructure, sand and gravel production, energy and building projects. Their portability and reduced environmental footprint make them ideal for urban and rural settings alike.

What is a Stationary Crusher, What is it Used For, How Does it Work, and Where is it Used?

A stationary crusher is a large-scale fixed crushing facility designed for continuous, high-capacity material processing. These systems are permanently installed and used primarily in quarrying, cement plants, and aggregate processing facilities.

The workflow starts with trucks delivering raw material to a feeder, followed by primary, secondary, and tertiary crushing stages. Vibrating screens and washing systems are often integrated. The final product is graded and moved to stockpiles via conveyors. Stationary plants provide high stability, automation, and processing volume, making them suitable for long-term industrial applications.

Applications: Aggregate production, mining, cement processing, concrete and asphalt manufacturing.

Differences Between Mobile and Stationary Crushers

  • Mobility: Mobile crushers can be relocated; stationary ones are fixed.

  • Installation: Mobile crushers offer quick setup; stationary systems require civil work and infrastructure.

  • Economics: Stationary systems are cost-efficient for high-capacity use; mobile systems are better for temporary projects.

  • Power Source: Mobile crushers can run on generators; stationary ones depend on grid power.

  • Deployment: Mobile crushers suit dynamic sites; stationary crushers are best for continuous, stable production environments.

What are Crusher Liners, What are They Used For, How Do They Work, and Where Are They Used?

Crusher liners are protective, replaceable steel components installed inside crushers to protect the inner walls from wear during operation. They are typically manufactured from high manganese or chromium steel alloys, capable of withstanding extreme impact and abrasion.

During crushing, material is compressed and impacted against the internal surfaces of the crusher. Liners absorb these forces, preventing direct damage to the machine’s main body. They also help direct the material within the chamber for optimal breakage and reduce undesired blockages.

Liners are vital for maintaining crushing efficiency and structural integrity. They are used in processing hard stone like granite, basalt, in cement clinker crushing, and concrete recycling. Regular maintenance and timely replacement of liners reduce operational downtime and increase productivity.

Applications: Quarry operations, mining, cement plants, concrete recycling, and aggregate manufacturing.
