11 Crushing and classification - particles.org.uk

In Summary, Kick's law is better for larger particles and Rittinger's for fine grinding, see Figure11.5. Large particles are easier to break than smaller ones as they have more cracks and faults. Often the laws are used in conjunction with empirically given constants: it can be dangerous to use the book values without some test work.

Oct 25, 2016· size reduction,laws involved in size reduction,application & mills 1. SIZE REDUCTION Size reduction is the process of reducing the particle size of a substance to a finer state of subdivision to smaller pieces to coarse particles or to powder. Size reduction process is also referred to as comminution and grinding.

Unit OperatiOn Size Reduction - جامعة تكريت

It has been found, experimentally, that for the grinding of coarse particles in which the increase in surface area per unit mass is relatively small, Kick's Law is a reasonable approximation. For the size reduction of fine powders, on the other hand, in which large areas of new surface are being created, Rittinger's Law fits

Rittinger (1867), Kick (1885) and Bond (1952) all proposed empirical laws to estimate the specific energy requirement for accomplishing a given extent of size reduction expressed in terms of the initial and final particle size (length dimension) and an empirical constant.

Rittinger and Kick's Laws of Crushing

I happen to be one of those who believe that Rittinger probably meant what he said when he wrote what Stadler has quoted, "the increase of the surfaces exposed is directly proportional to the force required for reducing" "and therefore also to the work absorbed in effecting the separa­tions." (The italics are now mine instead of Rittinger's or Stadler's.)

Mill (grinding) - Wikipedia

A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().
