Enclosed by Design: Reliable Bulk Material Handling for Cleaner, Controlled Operations

As environmental expectations increase and bulk material operators seek greater control over product quality, enclosed storage and conveying systems are becoming an increasingly important part of modern dry bulk handling. Whether handling biomass, fertilizers, ores, concentrates, or industrial minerals, operators need systems that protect material from weather exposure, help limit dust emissions, and maintain stable, reliable performance under demanding site conditions.

TAKRAF Group supports these requirements with enclosed storage and handling technologies engineered for high-capacity applications, challenging material and complex operating environments. TAKRAF Group’s experience spans mining, fertilizers, power generation, steelmaking, and port-related applications, where robust system design, careful equipment selection and lifecycle support are essential to long-term performance.

Recent global references underline the growing demand for these solutions. At a major copper operation in the Democratic Republic of Congo, TAKRAF Group supplied an enclosed stockyard package comprising a radial boom stacker, a bridge scraper reclaimer, two portal scraper reclaimers, and an overhead tripper conveyor. The scope illustrates how enclosed storage can be integrated into a wider material handling concept to support reliable buffering, reclaiming, and onward transport.

In another demanding African application, TAKRAF Group supplied a 400 tph portal scraper reclaimer for an enclosed urea storage facility at a mega fertilizer plant in Nigeria. Urea’s hygroscopic behaviour required specific design measures to prevent moisture ingress and product degradation. Conveyor galleries and transfer towers were fully sealed, and the reclaimer was equipped with a de-lumper to break down material agglomerations formed during storage. This application demonstrates the importance of adapting enclosed storage systems to the material properties and operating environment from the earliest design stage.

TAKRAF Group has also delivered enclosed storage solutions across Asia. In Japan, four large portal scraper reclaimers were supplied as part of a material feeding system for a multi-commodity power plant using thermal coal and biomass. Each machine is rated at 1100 tph and is capable of restoring and blending material. Because two machines operate on the same rail within the same building, a dedicated safety and anti-collision system was incorporated. In China, TAKRAF Group supplied multiple semi-portal and portal scraper reclaimers for covered raw material storage at a major steel producer, highlighting the long-term reliability of these technologies in continuous industrial operation.

Handling material inside enclosed facilities brings distinct technical challenges. Moisture sensitivity, abrasion, stickiness, lump formation, and dust generation must all be considered during system development. TAKRAF Group’s stockyard portfolio includes combined stacker and reclaimer, bucket-wheel reclaimers, and scraper reclaimers, with each machine type selected according to the application, material properties and required storage function. Scraper reclaimers are especially well suited to automated enclosed storage facilities because they enable gentle, controlled, and reliable reclaiming of many difficult-to-handle materials.

Enclosed conveying is another key element of a cleaner and more controlled material handling chain. TAKRAF Group designs and supplies overland conveyors, in-plant conveyors and tube conveyors. Tube conveyors, also known as pipe conveyors, offer flexible routing, fewer transfer points and protection of both the material and the surrounding environment. Where required, they can be equipped with the patented TAKRAF Automatic Belt Training System, which continuously measures and corrects belt position to support stable operation at the discharge point.

Beyond equipment supply, successful enclosed storage projects depend on strong engineering, planning, and execution. TAKRAF Group supports clients with services from feasibility studies and solution development to capacity expansion, refurbishment, erection, commissioning, and lifecycle support. By combining proven technologies with application-specific engineering, TAKRAF Group helps operators transition to safer, cleaner, and more efficient enclosed bulk material handling.
