GRANULATOR Russian patent published in 2006 - IPC B01J2/02 

FIELD: granulating materials.

SUBSTANCE: granulator comprises rotating perforated hollow housing. The distance δ between the openings in the housing along the axis of the granulator is determined from the equation δ = (1.1-2.5)Rω_R/v_g, where R is the radius of the granulator housing at the site of intersection of the axis of the opening with the outer surface of the housing, ω_R is the radial component of the velocity of suspension, and v_g is the velocity of the settling of the particles of the suspension in the gravity field. The length of the cylindrical section of the opening is determined from the equation h = (0.4-0.9)dωv, where h is the length of the cylindrical section of the opening, d is the diameter of the opening in the wall of the granulator housing, ω is the radial component of the velocity of suspension in the opening of the housing, and v is the linear velocity of the suspension flow over the inner surface of the housing wall.

EFFECT: enhanced reliability.
