A primary crusher is a heavy-duty crushing machine used in quarries and mining operations to process large blocks of raw stone or ore in the first stage of size reduction. These machines typically feature feed openings ranging from 60 cm to 150 cm. The goal is to break down massive and unprocessed materials into sizes that can be handled by secondary and tertiary crushers.

Main Types of Primary Crushers:

  • Jaw Crusher: Ideal for hard and abrasive materials.

  • Primary Impact Crusher: Produces cubic output; suited for medium-hard materials.

  • Gyratory Crusher: Preferred in large-scale stationary plants.

Application Areas:

  • Aggregate production

  • Primary crushing in mining

  • Recycling (especially of concrete and asphalt)

 What is a Mobile Crushing and Screening Plant?

A mobile crushing and screening plant is a transportable and integrated system designed to process natural stones or construction waste directly at the job site. Mounted on wheeled or tracked chassis, these plants are known for quick setup, easy relocation, and operational flexibility.

Key Components:

  • Primary and secondary crushers

  • Vibrating screen units

  • Feed hoppers

  • Conveyor belt systems

  • Automation and control panels

Advantages:

  • High mobility and portability

  • On-site production without the need for fixed infrastructure

  • Low setup and operating cost

  • Efficient for both recycling and natural rock crushing
