SPIROGYRE System 

The SPIROGYRE sweep-auger is designed for flat bottom silos and free-flowing materials (wheat, corn, barley, grains...) to reclaim the remaining products once the gravity unload has been completed. The fully automatic design of the SPIROGYRE provides a safe and reliable reclaim all around the silo, without operator input. 

 

Two types of SPIROGYRE : 

S Type : the electric motor is inside the silo, directly coupled to a reducer driving the auger. 

Advantages : reduced space requirement, simple and efficient. 

Certification : ATEX II 2D 125°C, Zone 21 inside the silo. 

 

SCD Type : the motor is under the silo, the transmission is ensured by a V-belt drive system under a closed casing. 

Advantages : allows high gravity flows, heavy duty design, sturdiness, easy maintenance. 

Certification ATEX II ½D 125°C, Zone 20 inside the silo, Zone 21 outside the silo.. 

 

SPIROGYRE Range : for silos from 6 to 38m diameter with conveyed discharge capacities from 17 to 300 TPH and gravity discharge capcities from 300 to 1000 TPH as standard (depending on the product). Special "optional" outlet hoppers are available if higher gravity discharge rates are required.  

 

Options : clearing screw, wiper brushes, level detector(choke detection in the central outlet hopper), parking position detector, special flighting, special outlet hopper, heavy duty advance wheel, additional advance wheel, reinforced construction for Soya Beans, Peas, Beans, Rice and Wood Pellets.
