Silo unloaders

Laidig is an industry leader in bulk storage and reclaim, specializing in systems for extracting hard-to-flow raw materials from conical and/or flat-bottom silos.

When materials stored in silos do not discharge properly, two types of actions are typically taken:

• For large silos: Workers enter to manually unload the material with shovels.
• For smaller silos: The walls or cone of the silo are struck to dislodge the material and enable flow.

In either case, these methods have significant drawbacks. In the first, there is a severe risk to human life, and in the second, long-term damage occurs due to dents in the silos. At Clivio Solutions, we offer the ideal solution to prevent workers from entering silos or striking their walls.

Key advantages of Laidig extractor systems include:

• Safety: Eliminates life-threatening risks for operators.
• Sanitation: Prevents rat holing and material buildup.
• Traceability: Ensures FIFO (First In, First Out) system compliance.
• Capacity: Enables complete filling and emptying of silos, maximizing their capacity.

When we talk about the cement industry, we have the particularity that a large portion of the cement is stored in domes. In this situation, material discharge becomes complex and requires specialized systems to achieve effective and efficient discharge.

In response to this, the Fluidized Screw system from Laidig is designed to eliminate traditional fully fluidized floors, which are prohibitively expensive in large storage diameters. The Laidig system uses fluidized radial channels to clean a large portion of the storage silo and a mechanical screw to extract the remaining material piles. This provides nearly total and fully automated cleaning, while also breaking up hard material and avoiding dead zones.

The Fluidized Screw recovery system integrates the best of two proven technologies: the efficiency of air gravity conveyors and the robustness of mechanical screw reclaimers.

There is also the possibility of storing cement in conical silos. In these cases, the ideal equipment for your application is the Cone Bottom model (available in both electric and hydraulic versions, depending on the requirement).

No matter the discharge issue with your silo, together with Laidig, we have the ideal solution to protect your company's team and prevent risks.
