Geometrica is the industry leader in domes for automated ring piles, having provided the majority and the largest domes in the world for this application.

A slewing stacker at the center stacks the material and creates the pile, while a bridge or a portal rake reclaims the material from a face of the pile. Limestone, clay, marl, coal, wood chips, fertilizers, sulfur and many other materials are stored in automated ring piles.

 
 
 

Geometrica geodesic domes have been built over piles of over 140m in diameter, and it is feasible to span up to 300m.

Typically, a dome for this application will need to cover an additional 3m to 6m width area around the base circumference of the pile for reclaimer clearance and circulation of maintenance personnel or small vehicles. Thus, the diameter of a dome for this application is usually 6 to 12m more than the pile's diameter. The dome's height is normally set at about 1/3 of the diameter for efficiency, but may be substantially lower or higher if desired.

Geodesic domes for ring piles also need to clear the reclaimer at its highest point near the perimeter of the stockpile, as well as provide a minimum height for the vehicles in the free area around the material. Instead of using an expensive vertical wall to achieve this, Geometrica can supply domes with elliptical or compound parabolic profiles that have a steep slope near the perimeter.
