Gimat flexible screw conveyors

Flexible screw conveyor

Flexible auger conveyors are capable of conveying a wide range of dry bulk solids (free flowing powders, granules, small pellets) in any direction

Dust protection

Protection against product inflitration by static and dynamic seal rings

Easy cleaning

By gates located at the pick up and unloading positions of the conveyor

Flexible screw conveyors to avoid obstacles in the plant

This type of powder transfer systems easily fits to existing plants thanks to its flexibility to overcome significant differences in height and cover long distances. The rotary spiral is made of carbon or stainless steel thermally treated in round, rectangluar or squared sections, depending on the application required. The spiral drive shaft is supported by means of roller bearing inserted in the flanged body of connection with the electric motor: in this way the motor bearing are not affected by the stresses transmitted by the spiral.

Our flexible screw conveyors can easily integrate with a complete range of upstream and downstream powder handling equipment, also with portable base frame with wheels.

ATEX - Explosion Proof Protected
All Gimat flexible spiral conveyors are available ATEX rated for use in explosive atmospheres (Directive ATEX 2014/34/EU FOR ZONE 2-22 / ZONE 1-21).
