Author, according to the principles of thc dynamics, analyses stock on the chute. There are six forces effecting it: gravity, inertial centrifugal F, reactionary force of chute to stock N, friction F_f, inertial Coriolis'S force F_k and the chute exerts two forces on the stock. Thus deriving unified stock distribution equation of expressed stock distribution which can be applied to both the rotative distributor and nonrotative distributor: ? This equation indicate effect of stock distribution of the following ll variables: length of the chute ι_υ, angle of the chuteβ, rotation speed of chute ω, coefficient of friction μ, initial speed of stock C_o, weight of stock Q, grain size and shape of stock (about s), density of gas γ, gas vclocity v and depth of stock line h. Change of one or several variables must lead to change of the stock distribution. These change can be quantitatively calculated by equation(69). Equation(69) is not only suitable to rotative distributor of chute, but also suitable to nonrotative distributor of bell. When ω=0, equation (69) changes into the stock distribution equation of bell type.
