Product Description:

The ES Series Tubular Screw Conveyor system is highly versatile offering numerous solutions for conveying powdery or granular materials. Screw Conveyors and Feeders are manufactured in carbon steel or stainless steel with a suitable surface finishing. Specialized coatings are optional for electrostatic prevention and corrosion resistance.


Depending on the characteristics of the material different models of conveyors or feeders are available in applications like concrete production (cement, fly-ash, filler dust, silica fume), asphalt production (hot and cold filler dust), premixed building materials (dry plasters, sand, cement, additives), glass processing (calcium carbonate, soda, sand, etc.), foundries (sand, bentonite), and many others.


These Tubular Screw Conveyors are available with ATEX, zone 22 certification.


We offer professional engineering design and consulting service.
