A mobile crusher is a flexible and portable machine designed to crush stones and minerals directly at the site of operation. Mounted on wheels or crawler tracks, it allows quick installation and rapid deployment across job sites. The typical components of a mobile crusher include a feeding hopper, primary and secondary crushers, vibrating screen, conveyor belts, and control panel.

The working principle involves feeding raw material into the crusher unit where it is initially reduced in size by the primary jaw crusher. The partially crushed material is then transferred to a secondary impact or cone crusher for further reduction. Final output is screened and separated into different sizes.

Mobile crushers are used in road construction, urban demolition, recycling operations, small-scale mining, infrastructure works, and emergency disaster clean-ups due to their mobility and versatility.

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

A stationary crusher is a permanent installation used in high-capacity and long-term operations. These plants are built on concrete foundations and feature heavy-duty equipment for constant production. Components include feeders, jaw or cone crushers, screening units, conveyor systems, and automation controls.

Material is fed into the system, crushed in stages, screened, and then stockpiled. Stationary crushers are typically powered by electricity and integrated into fixed site operations.

They are widely used in quarrying, mining, cement production, dam construction, and asphalt manufacturing where volume and consistency are key priorities.

Differences Between Mobile and Stationary Crushers

  • Mobility: Mobile crushers can be relocated; stationary units are fixed in one location.

  • Capacity: Stationary systems support higher output than mobile ones.

  • Setup: Mobile crushers are faster to deploy; stationary plants require detailed site preparation.

  • Power: Diesel is common in mobile crushers, while stationary units use electric motors.

  • Application: Mobile units are suitable for short-term projects; stationary plants fit long-term industrial use.

What Are Crusher Castings, What Are They Used For, How Do They Work, Where Are They Used

Crusher castings refer to components manufactured through metal casting processes for use in crushing equipment. These parts are made from high-strength materials such as manganese steel, high-chromium alloys, and cast iron.

Main casting parts include:

  • Jaw crusher plates

  • Cone crusher mantles and concaves

  • Impact crusher rotors, blow bars, and liners

  • Screen panels and frame supports

  • Conveyor drums and pulleys

These castings provide resistance to wear, impact, and heat. They are essential for maintaining crushing efficiency and reducing maintenance downtime. Their use is widespread in quarries, mining facilities, construction recycling plants, and heavy-duty crushing applications.
