A mobile crusher is a portable crushing and screening unit designed to reduce large materials such as rocks, concrete, or asphalt into smaller, reusable aggregates. Its mobility means it is mounted on a track or wheeled chassis, making it easy to transport and operate at various job sites.

The main function of a mobile crusher is to enable on-site material processing, reducing the need for transportation and improving efficiency. It contributes to faster project completion, lower costs, and more sustainable operations.

It works by feeding raw material into a hopper. The material then passes through a primary crusher (usually a jaw crusher), where it is broken into smaller pieces. It may then go through secondary or tertiary crushers, and is finally screened into different sizes. Conveyors move the finished materials to stockpiles.

Mobile crushers are used in:

  • Road and highway construction

  • Dam building

  • Quarry operations

  • Mining sites

  • Construction and demolition recycling

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 installation used for continuous, high-volume crushing. Unlike mobile crushers, these systems are permanently installed and best suited for long-term production in industrial environments.

Stationary crushers crush hard materials such as rocks and ores into desired aggregate sizes. The setup includes primary crushers (jaw), secondary crushers (cone or impact), tertiary crushers, vibrating screens, conveyors, and sometimes washing units.

Raw material is delivered by trucks, crushed in multiple stages, screened, and stored. These systems are reliable for large-scale operations and produce high-quality aggregates.

They are used in:

  • Permanent quarry plants

  • Ready-mix concrete and asphalt production

  • Port and dam filling

  • Mining operations

  • Heavy construction and infrastructure projects

Differences Between Mobile and Stationary Crushers

Mobile crushers offer mobility, flexibility, and are ideal for temporary or project-based operations. Stationary crushers offer high capacity and efficiency, better suited for permanent installations. Mobile systems are easy to set up and relocate but have lower capacity. Stationary systems take longer to install but handle larger volumes with better performance over time.

What are Crusher Castings, What are they Used For, How Do they Work, and Where are they Used?

Crusher castings are wear-resistant parts used inside crushing machines to perform the actual breaking of materials. These parts are made through casting processes using special alloys and designed to withstand intense impact and abrasion.

Common crusher castings include:

  • Jaw plates

  • Blow bars

  • Rotor paddles

  • Liner plates

  • Chamber wear parts

As material passes through the crusher, it impacts these cast components and breaks into smaller sizes. Castings are typically made from manganese steel, high-chrome iron, or composite alloys.

Crusher castings are used in:

  • Stone quarries

  • Mining operations

  • Construction waste recycling

  • Aggregate production plants

High-quality castings improve crusher efficiency, extend service life, and reduce maintenance costs.
