Process for the granulation of glass melts

摘要

There is described a process and an apparatus for the granulation of glass melts by bringing the melt into contact with water, in which there is obtained a homogeneous granulate without oversize grains and glass threads. This is attained by impacting the vertically downwardly flowing glass melt all around with laterally slanting downwardly directed high pressure water jets. The apparatus consists essentially of an overflow channel to an overflow funnel and a collecting container, wherein there is arranged below the overflow channel a preferably U-shaped nozzle carrier which entirely or partially surrounds the melt and carries nozzles with a conical angle of 15 DEG -180 DEG sloping downwardly.
