ABSTRACT:
Sulphur is obtained to the desired granulation and at the same time cooled by means of a directed hollow cylindrical jet of melted sulfur, on either side of which, i.e., both inside and outside the cylinder of molten sulfur, there are jets of cold water, the three jets directed onto a disk which disk is able to turn freely. The jets of water and sulfur strike the disk between the middle of the disk and its outer edge and make it turn, while at the same time the sulfur hardens into granules. The turning spins the granules off the disk. The fact that there are two jets of water leads to a better particle size of the sulfur and, because there is a better contact between the water and the sulfur, prevents any hardening of the sulfur upon the disk.
