Abstract

PURPOSE: To prepare solid particulate materials of various particle sizes by a method wherein a nonbroken cohesive flow of a melt of a solidifyable material is broken into a particulate material by contacting it with a rotating cooling liquid disposed under a centrifugal force, and the particulate material is cooled rapidly.
CONSTITUTION: A molten material 22 is a material which has a surface tension of 10W2,500dyn/cm and a viscosity of 10-3W1 poise at a temperature (in °K) corresponding to 25% of its equilibrium melting point. A cooling fluid 29 being in a substantially liquid state is placed in a cup-shaped member 11 and the member 11 is rotated by a shaft 12 to generate a centrifugal force, thereby causing the fluid 29 to become the rotating cooling fluid which forms a lining on the wall and adheres to the side wall 15 of the member 11. The molten material 22 in a container 18 fitted with a heater 21 is applied with a gas pressure P if required and is caused to flow through an orifice 20 to break it into spherical particles and a particulate material, and the particles and particulate material are contacted to the fluid 29 on the wall 15 and is cooled rapidly in the fluid 29. After a batch process is completed, the rotation of the member 11 is stopped, a screw at a through hole 17 provided at a bottom part 13 is removed and the solid particulate material is discharged together with the fluid 29.
