Crushers : Smooth Roll Crushers The maximum size of the product is 2d. These operates most effectively when set to give a reduction ratio of 3 or 4 or 1. That is the max diameter of the particle is 1/3rd or 1/4th of that feed. The forces exerted by these rolls are very great from 8700 – 70000 N/cm.

• Much more versatile than smooth roll crusher • Best example – Break and reduction rolls of wheat milling • Disintegrators are toothed roll crushers in which the corrugated rolls are rotating at different speeds • Size reduction is by compression, impact and shear and not by compression alone, as in the case of smooth roll crushers

Roll Crusher Mineral Processing amp Metallurgy. How to calculate the Roll Crusher Capacity using a Formula. The theoretical capacity of crushing rolls is arrived at simply by calculating the volume of the ribbon whose cross section is the area of the discharge opening, and whose length is the peripheral speed of the roll faces per unit of time.

methods. For example, a singleroll crusher, employ shear together with impact and compression. Shear crushing is normally used under following conditions. When material is somewhat friable and has relatively low silica content. For primary crushing with a reduction ratio of 6 to 1.
