Roll Crusher

A roll crusher is a machine used to crush materials by compressing them between two rotating cylindrical rolls. The rolls rotate in opposite directions, pulling the material through and breaking it down into smaller, uniform-sized particles. Roll crushers are widely used in mining, metallurgy, chemical, and building materials industries for secondary and fine crushing of medium-hard to hard materials.

WORKING PRINCIPLE OF THE ROLL CRUSHER

** The basic construction of a roll crusher typically includes two parallel cylindrical rolls mounted on a frame, rotating towards each other.

** The material is fed between the two rotating rolls through a feed opening.

** As the rolls rotate in opposite directions, they pull the material in and crush it by compressive force between the rolls.

** The crushed material size is controlled by the gap or distance between the two rolls.

** The crushed material passes through the gap, with finer particles exiting freely, while larger particles remain for further crushing.

USAGE OF THE ROLL CRUSHER

** Roll crushers are valued for their ability to crush medium-hard to hard materials with a consistent and uniform particle size.

** They are commonly used for secondary and fine crushing of materials such as coal, ore, limestone, clay, and other minerals.

** Roll crushers come in various sizes and configurations, including single-roll and double-roll designs, with smooth or toothed rolls depending on the crushing requirements.

** Some advantages of using a roll crusher include low dust generation, relatively low noise, energy efficiency, and the ability to produce a controlled particle size with minimal fines.
