In bolted silos, each component is designed to ensure high mechanical strength, operational safety, and long-term reliability, even in complex installations or demanding environmental conditions.
This section outlines the technical elements that define the modular panel system, with a focus on devices and solutions that optimize material handling and support operational continuity.<\/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

SEALING GASKETS<\/h3>\n
\n

Gaskets, positioned at the junction points between the different sections forming the silo, play a key role: they must withstand wear and provide protection against weather conditions. The materials selected by Poggi ensure long-term sealing performance, contributing to the overall stability and efficiency of the structure.<\/p> <\/div>\n <\/div>\n <\/div>\n <\/div>\n

LOADING SAFETY<\/h3>\n
\n

The Poggi silo is equipped with a safety system designed to prevent overpressure or underpressure conditions.
To start loading, the operator connects the pipe to the silo by moving a handle: this action activates an indicator on the control panel. Only at this point can the butterfly valve be opened from the control panel, allowing material to enter. This procedure ensures that loading takes place only when the silo is properly ready, preventing overloads or unsafe operations.<\/p> <\/div>\n <\/div>\n <\/div>\n <\/div>\n

TWO-WAY SAFETY SYSTEM<\/h3>\n
\n

The silo is equipped with a two-way safety system to prevent overpressure or vacuum conditions.
In case of filter blockage, an electronic pressure sensor automatically stops loading by closing the butterfly valve.
If this first level of protection fails, a second mechanical system intervenes to rebalance the pressure inside the silo.<\/p> <\/div>\n <\/div>\n <\/div>\n <\/div>\n

CONNECTION OF COMPONENTS<\/h3>\n
\n

Bolting is a key structural element in bolted silos, as it ensures the mechanical integrity of the entire structure. Depending on the installation environment (e.g. marine conditions), different types of bolts can be used, with varying sizes and protective treatments. Each bolt contributes to the overall stability of the silo, ensuring a strong and durable connection between the panels.<\/p> <\/div>\n <\/div>\n <\/div>\n <\/div>\n

INTERNAL LINING<\/h3>\n
\n

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

VOLUMETRIC DOSING<\/span><\/strong>
Material dosing is carried out via screw conveyor, adjusting the operating time based on the silo\u2019s nominal capacity. A reliable solution that ensures operational continuity and consistent output, particularly suitable for homogeneous materials and repetitive working cycles.<\/p>

ELECTRONIC DOSING WITH LOAD CELLS<\/span><\/strong>
For applications requiring precision, traceability and certified dosing, a loss-in-weight weighing system can be integrated. Load cells connected to an electronic terminal ensure reliable measurements, with cycle recording and controlled, verifiable recipe management.<\/p>

REMOTE MANAGEMENT AND TRACEABILITY OPTIONS<\/span><\/strong>
Upon request, dosing systems can be integrated with digital interfaces for remote control, data visualization from external terminals and automatic report generation. This enables advanced silo management even remotely and full integration into automated systems or Industry 4.0 environments.<\/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

Efficient separation between air and solid particles reduces the risk of emissions into the atmosphere and preserves the integrity of the stored material, preventing waste and contamination. Depending on the type of material stored in the silo, different types of filters can be installed, optimized for particle size distribution or the chemical nature of the dust handled.\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t
