Abstract
The width of static mass, the height of summit, the height of tongue end, the difference of these both heights and the angle composed by the surface of falling particles in the mixing zone and horizon in the flow pattern of particles in the cross section of a horizontal rotating cylinder were measured experimentally in order to obtain some informations for the designing and operating of such a cylindrical apparatus. The relations between the measured values of these elements and the volumetric charge ratio of particles in the cylinder F/V and the mixing Froude number N2R/g were analysed. It was examined that these values can be expressed by several simple functions of F/V and N2R/g.
The condition to obtain the similar flow patterns in different cylinders is to give a constant value to N2R/g holding the value of F/V at a constant, was confirmed as an important result of the present work.
