It is a cylindrical silo with a conical hopper, designed for storage of bulk materials, sawdust and wood chips. The silo is located on a steel substructure. GG silos can be equipped with a screw discharge system in the bottom conical part of the hopper, with closure by means of a rotary feeder at the outlet of the material. Pneumatic conveying of the material is most commonly used for filling the silo, using a filtering device located on the silo ceiling, or using a cyclone separator located on the silo ceiling. GG silos can be equipped with relief membranes to allow storage of explosive dusts, access ladders and dry pipework. GG silos are manufactured in segments to ensure that they can be transported by standard trucks without the need for oversized loads. The silo is assembled by crane on site at the client's site. The total assembly time is approximately 24 to 36 working hours depending on the silo equipment. According to the client's requirements, the silo is equipped with an access ladder, service platform, railing, dry pipe, aeration nozzles, filtering equipment and other components.
