Poggi big bag dischargers<\/strong> (also known as bulk bag unloaders) are designed to facilitate the opening, containment, and controlled transfer of bulk materials contained in sacks and big bags. Made of carbon steel for structural stability and long service life, they are robust, compact, and versatile, easily integrating into plants where a regular feed of materials such as cement, lime, technical powders, or granules is required.<\/p>

Available in various configurations, with electric or diesel motors, they are fully compatible with screw conveyors, belt conveyors, weighing, and dosing systems. The internal structure is designed to ensure complete bag emptying (big bag discharge<\/em>) and maintain a constant, controlled flow to downstream systems.<\/p>

The compact, modular design allows rapid installation even in tight spaces, facilitating loading, opening, and maintenance operations. Big bag dischargers can be equipped with lump breakers, vibrators, level sensors, dust covers, and lifting systems, adapting to diverse operational and environmental conditions. They are easy to move thanks to built-in lifting points; a standard forklift is sufficient, without the need for special equipment.<\/p>

Poggi offers a complete range to meet every need: in addition to automated systems, manual-load bag breakers are also available, ideal for small sites or plants requiring simple and effective solutions. These models provide operational safety and ease of use and can be fully customized in color and branding for seamless integration with the company\u2019s visual identity.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

In Poggi Big Bag Dischargers, every component is designed to ensure durability, reliability, and ease of use during unloading operations of bagged materials. The structure is built to withstand mechanical stress and operate efficiently even under demanding conditions.<\/p>

Once positioned, the bag rests on the reinforced grid; the integrated blade cuts the bottom, allowing the material to flow out, which is then collected and conveyed to the next stages of the process. The standard configuration offers a storage capacity of 3 m\u00b3, equivalent to three bags, providing high operational autonomy and greater flexibility for the operator, who can manage the process even remotely.<\/p>

The discharge hopper ensures smooth material handling, preventing blockages and minimizing residue. This results in a steady flow toward screw conveyors, belts, or dosing lines, reducing processing time and maintaining operational continuity. Integration with silos, existing plants, or handling systems makes Poggi Big Bag Dischargers a versatile and safe solution for feeding bulk materials.<\/p>

They are available in three configurations: electric, diesel-powered, or manual-load.
The electric and diesel versions differ in power supply: the electric version connects to the mains, while the diesel version features a generator unit for fully autonomous operation.
The manual-load version is available in both power options and is designed for direct bag loading by the operator, ideal for applications with small material quantities.<\/p>

This versatile range ensures maximum operational flexibility, even in environments without electrical supply.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

The screw conveyor, available in different types depending on the material to be handled, is designed to manage products with widely varying physical characteristics: from fine powders such as lime and cement to more abrasive or challenging materials like plastic granules, fertilizers, and ashes. Each conveyor is sized according to the required throughput and the type of material being processed.<\/p><\/div><\/div><\/div><\/div><\/div><\/div> <\/div>\n <\/div>\n <\/div>\n <\/div>\n

INTERNAL LINING<\/h3>\n

Different types of internal linings can be applied, selected according to the nature of the material to be handled. These linings serve a dual purpose: they protect internal surfaces from wear, abrasion, or corrosion, while also facilitating material flow toward the outlet, reducing friction and accumulation. The correct choice helps optimize operational efficiency and extend the silo\u2019s service life.<\/p> <\/div>\n <\/div>\n <\/div>\n <\/div>\n

\n\t\t\t\t\t\t\t\t\tEXTRACTION SYSTEM<\/span><\/strong>\nIn Poggi big bag dischargers (with screw conveyor), material extraction occurs by gravity through a bottom opening equipped with a bag-breaking grid. The material is conveyed to transport systems such as screw conveyors or belts, with the option to integrate control valves, gates, or custom fittings for direct feeding.\n\nINTEGRABLE VIBRATION SYSTEMS<\/span><\/strong>\nTo facilitate the discharge of compact or difficult-to-empty materials, electric vibrators or selective vibration mechanisms can be installed. These devices prevent material stagnation and maintain a constant flow toward the extraction point.\n\nFLUIDIZATION<\/span><\/strong>\nFor dusty or lightweight materials, the bottom of the big bag discharger can be equipped with compressed air nozzles. Fluidization improves flowability, prevents accumulation, and optimizes discharge.\n\nFLOW CONTROL<\/span><\/strong>\nThrough screw conveyors with frequency inverters, the flow rate can be precisely managed, allowing controlled extraction according to operational needs. This approach reduces waste and improves dosing in subsequent process stages.\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t
