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

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

p – Size reduction ratio • Coarse grinding has RRs below 8:1 • Fine grinding can exceed 100:1 • Grinding of coarse particles in which the increase in surface area per unit mass is relatively small, Kick's Law is a reasonable approximation • Rittinger's law

At the finest grinding with a size reduction ratio of 128:1 (Fig. 7d), a 50.8 mm/25.4 mm ball mix at a 13:87 ratio was found to be the optimum mix. This indicates that the finer the product size, the higher the proportion of smaller balls that is required.

Generally, we need a very high reduction ratio to go from the run of mine to the liberation size. Therefore, it is necessary to divide the total R:1 into smaller ratios, thus it refers to multiple units of size reduction. The milling work is done in two circuits, …

Crusher Reduction Ratio. I have mentioned the fact that, as the % of voids in the crushing chamber decreases, the production of fines by attrition increases.

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.

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. Both crushing and grinding require energy to reduce the ore size. However, in grinding operations we consume much more eneregy than crushing, up to 100 times. More
