A mobile crusher is a portable crushing and screening unit designed for processing materials such as stones, rocks, rubble, asphalt, concrete, or ores directly on-site. It is mounted on a wheeled or tracked chassis and can be easily relocated between sites.

The operation begins when raw material is fed into the feeder unit. From there, it is transferred to a crusher (jaw, cone, or impact type), where it is broken down into smaller sizes. The crushed material is then screened and classified by size, and conveyed to storage or transportation via belts.

Mobile crushers are widely used in road construction, dam projects, infrastructure works, quarrying, mining, and recycling sites. They offer fast setup, on-site production, low transport cost, and high flexibility.

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

A stationary crusher is a fixed plant designed to perform high-capacity crushing and screening operations. It is intended for long-term use at a specific location, such as a quarry, mining site, or cement plant.

Material is fed via a bunker into the system. It is first crushed in a primary crusher and then further reduced in size by secondary and, if necessary, tertiary crushers. The final product is screened and conveyed to stockpiles.

Stationary crushers are preferred in large-scale industrial operations requiring continuous, automated, and high-volume output. While installation and investment are high, they offer unmatched efficiency and capacity.

Differences Between Stationary and Mobile Crushers

Mobile crushers are best suited for temporary, flexible, or field-based projects. They are easy to transport and quick to install but generally have moderate capacity.

Stationary crushers are designed for permanent, high-capacity, multi-stage operations and are ideal for integrating with automation systems. They offer superior performance and consistency but require long-term commitment and infrastructure.

What Are Secondary Impact Crusher Blow Bars, What Are They Used For, How Do They Work, and Where Are They Used?

Secondary impact crusher blow bars are wear parts attached to the rotor of the secondary crusher. Their purpose is to apply high-impact force to materials previously crushed by a primary crusher and reduce them to smaller, usable sizes.

As the rotor spins at high speed, the blow bars strike the material with intense force. Typically, there are three blow bars performing successive stages of crushing: coarse, intermediate, and final.

These components are made of abrasion-resistant alloy steels such as high-manganese steel. They are widely used in aggregate production, concrete additives, asphalt plants, mining, and recycling. Quality blow bars improve efficiency, extend service life, and reduce downtime.
