A twin-roll crusher is selected, like those given in the Roll Crusher capacity Table above, to serve as the reduction crusher. The smallest, 24 x 16 roll crusher shown in the Roll Crusher capacity Table above has enough capacity with a setting of 1 in. but the maximum size feed will be too large, that is, the stage of reduction is not large enough.

Double Roll Crusher Design
Hi, I''m a student and need to design a double roll crusher that can be used for crushing coal from 100 mm down to 50 mm at a rate of 300 tons per hour (tph). Where can I find the mechanical properties of coal and how do I determine the roll diameter, roll speed, torque and reaction forces on the shafts if the rolls have teeth? Any references would be appreciated.

4. * Roll crushers are used for producing additional reductions in the sizes of stone after the output of a quarry has been subjected to one or more stages of prior crushing. Roll crushers have a theoretical MAXIMUM reduction ratio of 4:1. If a 2 inch particle is fed to the roll crusher the absolute smallest size is 1/2 inch.

What Are the Differences Between 7 Types of Crushers? | Fote
Roll crushers reduce material by force generated from two relatively rotating drums. First, the material enters the feed opening along with the high-speed rotating roller drums, then it got crushed by strong compressive forces in the crushing chamber, and ultimately being discharged until its size smaller than the gap between two drums.
