Abstract
The production of wax beads from molten material comprises releasing droplets from nozzles contained within a tank which is filled with water. The water adjacent the nozzles is maintained at a temperature above the melting point of the wax by means of steam coils. As the wax droplets formed by the nozzles rise through the column of water they cool and solidify to form spherical beads. The solidified beads which float on the water are separated from the water over a weir and are collected and dried.
Claims8
Apparatus for the production of beads from molten material including:
- a container for holding a liquid;
- an inlet in said container for conveying said material for release within the liquid;
- at least one bead-forming nozzle in a lower zone of said container connected to said inlet;
- means for maintaining a temperature gradient within said liquid such that the temperature of the liquid adjacent the nozzle exceeds the temperature at the surface;
- and means for removing solidified beads from the surface of the liquid.
