Choice of feeder type depends on the physical properties of the specific material
Vibrating feeders are designed for supplying bulk, fine-grained, dice materials with a fraction of at most 20 mm, a density of at most 2 g/cm3, not prone to sticking during their transportation at an ambient temperature from -30° up to +50°
It is expedient to use swinging tray-type feeders for unloading the lumpy materials with changing humidity and particle size fluctuations (dolomite, limestone, frozen sand, crushed glass)
Dosing of microadditives (glass mass colorants and decolorizers) is performed with the help of spiral screw feeders with material agitators
The lining pads made of abrasive-resistant material, Castolin overlay welding on screw blades, Castolin powdering on screw housings are used to increase the service life
All feeders are made in a dust-proof housing, connecting flanges with seals ensure absence of emission of dust-like materials at the docking points with other equipment
