DRUM GRANULATOR GRANT

DRUM GRANULATOR GRANT


This drum gran­u­la­tor is a machine designed for con­tin­u­ous gran­u­la­tion of melted glass. The drum is mounted on two pairs of driving rollers in the sup­port­ing frame of the gran­u­la­tor, and it is locked in lon­gi­tu­dal direc­tion with axial rollers.


Inner surface of the drum is equipped with a spiral which moves the melted or gran­u­lated glass. Regard­ing the fact that the gran­u­lated glass only rolls over the inner surface of the drum, its abra­sive wear is very low, whereas both dura­bil­ity and reli­a­bil­ity of the machine are high. Water level is deter­mined with the drum design. The inlet drum side is equipped with a cir­cu­lar ring and the other side is tapered. The machine slopes towards the inlet or outlet side, and this effects over­flow of the cooling water. The drum is driven with an elec­tric gearbox through a chain and fric­tion drive. The melted glass is chuted in the drum. The time of gran­u­la­tion in the drum can be set with the drive rev­o­lu­tions. The cooling water is either chuted in the drum together with the melted glass, or it is fed sep­a­rately through the drum inlet or outlet. An elec­tric switch­board with switches, circuit break­ers and fre­quency changer of rev­o­lu­tions makes a part of the machine. Capac­ity of the gran­u­la­tor depends on customer’s require­ments.
