Operating principle

The silo is designed for pneumatic pressure load, usually using the compressor included with the material transport tanker. The product is fed into the silo through the filling pipe and the air is filtered by a special system (self-cleaning filter) that can be placed on top of the silo or on the ground. The product level within the silo is monitored through simple transmitters (min-avg-max), in continuous mode (% of filling), or by weighing the silo, ensuring control and ideal management of the stock, considerably facilitating the organisation of raw material supplies.

The internal pressure can be monitored via specific sensors that in combination with the control and safety system of the silo prevent unwanted deformation or breaking.

The product is extracted through a vibrating steel cone that can power various mechanical devices such as screw conveyors, rotary valves or vacuum pneumatic jacks.
