Our rotary and screw feeders are designed to handle various dry bulk materials and powders, including grains, plastics, chemicals, and minerals, with material compatibility depending on the housing material selected (cast iron, stainless steel, or carbon steel).
Precise metering is achieved through a rotating rotor or screw within a sealed housing, which controls the discharge rate. The drive assembly allows for adjustable speed, ensuring consistent material flow into your process stream.
Shaft seals and bearings are critical for preventing material leakage and ensuring smooth operation. Regular inspection for wear, proper lubrication of bearings, and seal replacement as needed are recommended to maintain optimal performance and longevity.
