Silo unloaders

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.

Below is an animation of the material recovery process:

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.

Flow measurement

Flow measurement

The need for flow measurement and control is essential in many stages of the process. Together with Jesma, we are able to measure product flow reliably, with two very useful alternatives depending on the application.

If we have available height space, the recommended system is JesIntake. However, if height is limited, the JesBelt weighing belts are the ideal solution.

The JesIntake range of scales is specially designed for inline weighing of bulk materials such as powders, granules, grains, and more, focusing on operational reliability and high precision. The equipment series includes a standard range of 13 sizes, with capacities from 12 m³/h to 2500 m³/h, making them suitable for handling high flow rates while maintaining high accuracy.

If height is limited, the solution to apply is a JesBelt conveyor, which features an incremental encoder (tachometer) mounted on the roller to allow continuous monitoring of the belt and ensure an immediate alarm signal in case of irregularities in belt transmission. The belt is equipped with load cells that guarantee high precision even with irregular material flow. The weighing conveyor is designed and built for continuous weighing of material transported on a belt or for regulating a specific material flow.

If an immediate solution is required, the JesBelt F1 is our standard range of belt weighers. With 1% accuracy and versatile functionality, it ensures precise and efficient performance. Its user-friendly design simplifies maintenance with easy belt replacement and integrated cleaning features, minimizing downtime.

The JesBelt F1 range is available in three configurations: basic, standard, and complete.

Pallet wrapping

Pallet wrapping

The Stretch Hood pallet wrapping system provides maximum load stability and protection. This innovative technology applies a tubular film that stretches and conforms to the shape of the load, offering stability and protection.

The Stretch Hood offers greater savings on consumables, faster wrapping speeds, complete load protection, transport safety, and a superior-quality finish that adds value to your palletized product.

Optional accessories include:

  • Vertical corner protector applicator system
  • High productivity kit (quick welding and buffer system)
  • Motorized unwinder
  • Load edge rounding system

The wrapping process becomes highly efficient and fast, thanks to the system's operational design. Additionally, you can include your brand or logo on the film, making it much more appealing and improving your brand positioning in both local and international markets.

Key advantages of the system:

  • Savings on packaging costs: The Stretch Hood system allows for up to 50% savings on film and energy consumables. It uses only the exact amount of stretch film needed to protect the load, reducing waste and excess film. Additionally, since it does not require heat combustion or gas installations, it also lowers energy consumption.
  • Total product protection: Stretch Hood is the only system that provides complete protection and waterproofing for the product. This total protection is achieved through the wrapping process and the properties of the Stretch Hood film, a multilayer film made of linear low-density polyethylene (LLDPE) with barrier properties against moisture, dust, and UV rays.
  • High packaging speed: Stretch Hood is the fastest packaging system, capable of wrapping up to 120 pallets per hour, compared to systems like shrink wrap, which wrap 60 pallets per hour. This is a decisive argument for many companies that choose to further automate and optimize their end-of-line production.
  • Additional stability and support: With Stretch Hood wrapping, the load remains secure and stable to prevent shifts, falls, or damage during transport. The Stretch Hood film is stretchable and, with the combination of vertical and horizontal contraction forces during wrapping, adapts to and secures the load, offering additional stability to palletizing.
