  • Design, Fabrication and Testing of a Double Roll Crusher

    distinguish crushing from grinding rather than mechanism of size reduction [4]. There are primary and secondary crushers. A primary crusher reduces large particles into smaller sizes for further crushing by the secondary crusher. Examples of crushers include jaw crusher, gyratory crusher and roll crusher.

  • Dual roll crushers, how they function

    If a 2 inch particle is fed to the roll crusher the absolute smallest size one could expect from the crusher is 1/2 inch. Roll crushers will only crush material down to a minimum particle size of about 10 Mesh (2 mm). A roll crusher crushes using compression, with two rolls rotating about a shaft, towards the gap between the rolls.
