    摘要: A process for the manufacture of glass raw material granular pellets is provided.The process comprises:(a) forming a mixture of powdered raw glass material with an aqueous solution of a binder, which can be converted into a solid upon exposure to an elevated temperature gas stream, said binder not adversely affecting the glass subsequently formed of said material,(b) directing a stream of gas at an elevated temperature upwardly through a substantially erect straight pipe having the upper end thereof connected to a solid-gas separator;(c) feeding said mixture into an opening in said pipe and into said upwardly flowing heated gas stream to disperse said mixture,(d) drying said dispersed mixture in said gas stream and bonding the particles in said dispersed mixture with said binder to form granular pellets thereof, and(e) separating said formed granular pellets from said gas stream in said separator.
