WebLaws governing size reduction Griffith theory-The amount of force to be applied depends on the crack length. Kick's law- Work required to reduce the size of a given quantity of material is constant for the same reduction ratio regardless of the original size. Rittinger's law-Worked use for particulate size reduction is directly proportional to the WebKick's law assumes that the energy required for size reduction is proportional to the logarithm of the ratio between the initial and the final diameters. The unit of Kick's …

WebSize reduction is accomplished by shearing forces that cause the material to fracture releasing most of the applied energy as heat. 2. A general equation giving the power required for size reduction is: dE/dL = KL n. and from this can be derived (a) Kick's Law in which n = -1 and which may be integrated to give: E = K K f c log e (L 1 /L 2) (b) ... Web11 feb. 2024 · Kick’s law 2 1 ln d d KE K KK = Kick’s constant, d1 (m) = the average initial size of pieces, d2 (m) = the average size of ground particles. d1/d2 = the size reduction ratio (RR) and is used to evaluate the relative performance of different types of equipment. ebay sentry earbuds
