PROBABILITY OF SIZE REDUCTION OF EMULSION DISPERSE PHASE PARTICLES IN A HIGH-SPEED ROTARY DISPERSER

摘要

The conditions of size reduction of particles of an emulsion disperse phase during its movement in the holes of the rotor and stator of a high-speed rotary disperser are studied. Analytical relationships that allow determination of the magnitude of tensile forces acting on the ends of the particle located on the sharp edge of the rotor hole were obtained. It is shown that the magnitude of tensile forces depends on the particle mass, angles of the hole edges, diameter, and angular speed of the rotor. As the rotation speed increases and the rotor hole edge angles decrease, the tensile forces acting on the particle ends increase, which increases the probability of its fragmentation into two parts.
