It consists of 3 rollers.
Rollers are made up of hard abrasion resistant material.
Rollers are arranged very close to each other’s.
Rollers are rotated at different speed & in opposite directions.
Material gets crushed when it comes in between rollers.
Working:

From hopper material come between roller no.1 and roller no.2 and is reduced in size.
The gap between roller no.2 and roller no.3 is less than that between roller no.1 and roller no.2
Due to which material is crushed and gets mixed.
A Scraper is provided to remove the material from roller no.3
