SPIROGYRE System 
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. 
 
Three 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-HYDRAUGYRE Type : this option, evolved from MORILLON's expertise in the extraction of difficult products, combines the structure of a traditional SPIROGYRE sweep auger and the hydraulic motorisation used on HYDRASCREW unloaders, and is suitable for products whose repose angle can occasionally exceed 45 degrees. 
Advantages : high torque, reduced space requirement, sturdiness. 
 
SPIROGYRE Range : for silos from 6 to 38m diameter and allows discharge capacities from 25 to 500 TPH depending on the product. 
 
Options : clearing screw, wiper brushes, level detector(choke detection in the central outlet hopper), parking position detector, special flighting, special outlet hopper, heavy duty wheel, additional wheel, reinforced construction.
