A mobile crusher is a portable crushing and screening unit used for reducing natural rocks, concrete, ores, and similar hard materials into smaller, usable aggregate sizes. Mounted on a trailer or tracked chassis, it allows for easy transport between different job sites, making it ideal for temporary or mobile operations such as road construction, mining sites, dam works, and urban redevelopment.

The system starts with raw material being loaded into a feed hopper. From there, the material is transferred via a vibrating feeder to the crusher unit (jaw, impact, or cone). After the initial crushing stage, the material is directed to the vibrating screen, where it is separated into various sizes. The final products are conveyed to stockpiles via belt conveyors.

What Is a Stationary Crusher? Function, Operation, and Use Areas

A stationary crusher is a permanently installed crushing facility designed for long-term, high-volume material processing. It is commonly used in quarries, mining operations, and cement plants. These facilities are larger in scale, fixed in one location, and capable of handling massive amounts of raw material.

Material is delivered to the site and fed into a bunker, then processed through a primary crusher. Subsequent stages may include secondary and tertiary crushers, and the material is ultimately screened into different sizes. Due to their scale, stationary plants require significant infrastructure but offer high production capacity with lower maintenance in the long term.

Differences Between Stationary and Mobile Crushers

  • Mobility: Mobile units can move between sites, stationary units cannot.

  • Setup Time: Mobile crushers are operational within hours, stationary systems may take weeks to install.

  • Investment: Mobile units require less initial investment; stationary plants are more capital-intensive.

  • Capacity: Stationary systems have higher processing capacities.

  • Use Case: Mobile crushers suit short-term or shifting projects; stationary ones suit continuous, high-volume production.

Crusher Liners (Internal Linings): Definition, Role, Working Principle, and Application Areas

Crusher liners are internal wear parts mounted on the interior walls of crushing equipment. These liners, made of high-manganese steel or wear-resistant alloys, serve to protect the crusher’s body from direct abrasion and impact during the crushing process.

Their primary purpose is to absorb the mechanical stress and wear generated by material compression, fragmentation, and friction. The design and angle of the liners also optimize the crushing efficiency by guiding material movement inside the chamber.

These components are used in aggregate processing plants, stone quarries, mining sites, and recycling facilities. Because of their direct exposure to high-pressure and abrasive material, they must be replaced periodically to maintain equipment performance and prevent structural damage.
