A mobile crusher is a portable crushing and screening system designed to process materials such as stone, rock, concrete, and asphalt into smaller, manageable sizes. Equipped with wheels or tracks, these units can be easily relocated and quickly set up on various job sites.

Mobile crushers typically consist of a feeder, primary crusher (jaw or impact), secondary crusher (cone or tertiary), screening unit, and conveyor belts. Material is loaded into the feeder, passed through the crusher where it is crushed by mechanical force, and then screened and separated by size before being transferred to stockpiles.

Mobile crushers are widely used in construction sites, road projects, mining operations, quarrying, and recycling of demolition materials. Their mobility offers a significant advantage in dynamic or short-term operations.

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

A stationary crusher is a permanent facility designed for high-capacity crushing and screening operations. It is typically installed in one location and is used for long-term production.

Materials are transported to the plant by trucks, processed through primary, secondary, and tertiary crushers, and sorted by size using vibrating screens. The processed aggregates are then sent to storage or further processing.

Stationary crushers are commonly used in cement plants, large construction sites, dams, highways, and long-term mining projects. Though the initial installation is costly and time-consuming, they offer higher efficiency, greater durability, and better integration with automated systems.

Differences Between Stationary and Mobile Crushers

Mobile crushers are more flexible, easier to set up, and ideal for short-term or mobile operations. They have lower initial cost and can be relocated as needed. Stationary crushers are more powerful, support higher capacity, and are suited for permanent industrial facilities.

While mobile crushers are practical for on-the-go applications, stationary units offer consistent high-volume output and require less frequent maintenance.

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

Crusher liners are protective internal components installed inside crushing machines to shield the inner walls from wear, abrasion, and impact caused by crushing materials. They help preserve the structural integrity of the crusher and improve operational efficiency.

Typically made from high manganese steel or alloyed castings, liners absorb the energy of the crushing process. When rocks and hard materials strike the internal surfaces, the liners take the impact, gradually wearing down over time. Once worn, they can be easily replaced.

Each type of crusher, whether jaw, impact, or cone, uses uniquely designed liners that match the geometry and operational requirements of the machine. The material composition and thickness of the liners significantly influence the crusher’s performance.

Crusher liners are used extensively in quarries, mining sites, recycling plants, and heavy-duty construction applications.
