Classification of screw feeders

Tubular type—use seamless steel pipe to seal and transport materials, which can prevent dust from polluting the environment and improve working conditions. Vertical conveying.

U-shaped—good sealing performance, which has great advantages for occasions with large dust and environmental requirements. It can avoid the generation of dust during the transportation process. It is suitable for horizontal/small inclination angle transportation, and the inclination angle does not exceed 15°.

With shaft—suitable for dry powder and materials with small particles and no viscosity. Such as: (cement, fly ash, lime, grain, etc.).

Shaftless - Shaftless screw feeder is suitable for viscous or easily entangled materials, such as: (sludge, biomass, garbage, etc.).

Single drive—when the length of the screw machine is less than 35m.

Double drive - when the screw machine is greater than 35m.

Carbon steel——is a relatively common material, with low cost, good heat insulation effect, no cooling device is required, but the effect of anti-corrosion and anti-rust will be worse, and it is generally used for ordinary material transportation.

Stainless steel—Stainless steel screw feeder is made of 304 or 316 stainless steel, polished, wear-resistant, resistant to acid and alkali corrosion, not easy to rust, resistant to high temperature of 200°C, clean and hygienic, suitable for industries with strict hygiene requirements, such as food, medicine, sludge and other industries.
