Charging Apparatus
Charging Apparatus
a device for loading bulk materials into shaft furnaces (blast and kiln furnaces). It is used mainly in blast-furnace production. The charge is delivered to the charging apparatus by skips or conveyors. From the receiving funnel the charge passes first to the small bell and then to the large bell. The large bell lowers when the small bell is closed, which prevents a rush of gases from the furnace into the atmosphere. Rotating charge spreaders are used to provide even loading of the charge over the circumference of the furnace throat.
