Rittinger's constant
Web– Rittinger’s constant • For the size reduction of fine powders, in which large areas of new surface are being created, Rittinger's Law fits the experimental data better. Bond’s law • The work required to form particles of size Dp from very large feed is proportional to the square root of the surface to volume ratio of the product Webis called Rittinger's constant, and integrate the resulting form of eqn. (11.1), we obtain: E = K R f c (1/L 2 – 1/L 1) (11.3) Equation (11.3) is known as Rittinger's Law. As the specific surface of a particle (the surface area per unit mass) is proportional to 1/L, eqn. (11.3) …
