Reduction Ratio - an overview | ScienceDirect …
For dry grinding, we must multiply the reference W i by 1.3, which is obtained by wet grinding. 4) Reduction ratio R [BON 61a, BON 61b]: Bond proposes an optimum reduction ratio for rod mills [BON 61b, p. 545]. If the real ratio deviates, then W i must be multiplied by a correction coefficient (equation 26 in [BON 61b, p. 545]). For a ball mill, if the reduction ratio becomes …
CHAPTER 20: SIZE REDUCTION – EQUIPMENT FOR SIZE …
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, Kicks Law is a reasonable approximation • Rittinger’s law
4 Size reduction - Universitas Brawijaya
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
CPE: Lesson 13. Principle of Size Reduction
For example, coarse crushers have size reduction ratios of below 8:1, while fine grinders may present ratios as high as 100:1. However, large reduction ratios, such as those obtained when dividing relatively large solid lumps to ultra-fine powders, are normally attained by several stages using diverse crushing and grinding machines. A good example of this is the overall milling of …

Fine Grinding - an overview | ScienceDirect Topics
Fine grinding is very often carried out wet using slurry concentrations of up to 40% solids by volume. Wet grinding is generally considered to be more “efficient” than dry grinding, probably because of improved dispersion of the particles and reduced tendency for aggregation of fines. Grinding aids, typically surface-active agents, are available commercially for both wet and dry grinding ...
Crusher Reduction Ratio - Mineral Processing & …
We know from our examination of the crushing characteristics of these types that, for equal reduction ratios, the volume-reduction-ratio in the standard gyratory is considerably higher than it is in the fine reduction crusher. Therefore, if minimum production of fines is desirable, it is logical that the heavy end of the 7:1 reduction should be handled in the latter machine. …

Kicks law: putting p = 1, then integration gives: Writing C = KKfc, then Kicks law, is obtained as: This supposes that the energy required is directly related to the reduction ratio L1/L2 which means that the energy required to crush a given amount of material from a 50 mm to a 25 mm size is the same as that required to reduce the size from 12 mm to 6 mm. Bonds Law: Neither of these …

Determination of energy required in size reduction is generally done using either Kick’s law or Rittinger’s law. Kicks’s law is used for coarse grinding when the size ratio of original material to end materials is 8:1. Bond’s law and Retinger’s law are used for intermediate and fine grinding respectively, where ratios approach or ...
