PROCESS
DESCRIPTION
The solid feed system is required for feeding
glass frit of irregular shapes and sizes into
vaccum furnace opening at 5” negative pressure
through an airlock feeder system.
The
solid feeding system operates on the principle of Loss in weight
i.e. controlled material discharge. Material extraction rate through
rotary airlock below the weight hopper will continue at whatever
rate selected at set point feed rate 3-15 kg/hr (50-250 g/min).
The speed of the rotary feeder is continuously varied such as to
maintain loss of weight constant i.e at the set feed rate.
When
the weight of the material in weigh hopper reaches the preset minimum
value, the required material is refilled at a high feed rate of
2ton/hr in few secs. Thus the process is continuous.
The weighing
systems will be sturdy and rugged to work in the
high temperature expected out door and also to
withstand the jerks and vibrations.
