4 Size reduction - UB
d1/d2 is known as the size reduction ratio (RR) and is used to evaluate the relative performance of different types of equipment. Coarse grinding has RRs below 8:1, whereas in fine grinding, ratios can exceed 100:1 (Brennan et al., 1990). 2. Rittinger's law states that the energy required for size reduction is proportional to the
CHAPTER 11 SIZE REDUCTION - NZIFST
This size reduction operation can be divided into two major categories depending on whether the material is a solid or a liquid. If it is solid, the operations are called grinding and cutting, if it is liquid, emulsification or atomization. All depend on the reaction to shearing forces within solids and liquids. GRINDING AND CUTTING
Crushing Vs Grinding - Minerallurgy
The reduction ratio in grinding can up to 100, therefore it consumes a considerable amount of energy. Therefore, the optimization of grinding operation is very important. Energy.

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. To allow unbreakable material to pass through without damaging the machine, at least one roll must be spring mounted.
