Cylindrical Storage Silos

The silos are available in the capacity range of 30, 40, 50, 60, 70, 80, 90, 100 and 120m3, being divided into either horizontal or vertical sections. In general, the cement silo is usually equipped with aeration equipment protecting it from material arching and with filters arresting fine particles entrained by air escaping from the silo during filling. The silo is fitted also with various technological and inspection holes, a filling system, an exterior ladder and a walkway gallery. The silo shall be provided also with a system for monitoring the material quantity kept in store.

The system of storage silo is provided with necessary equipment for the receipt and delivery of loose materials such as pneumatic placers as well as bucket, belt and worm conveyors. The silos are made of steel of the S235JRG2 grade and may be provided with abrasion resistant (HARDOX) interior lining on customer‘s request. Silos designed for the food industry are made of stainless steel, or their internal surfaces can be provided with coatings certified for use in food applications. Exterior surfaces are coated with durable epoxide or polyurethane coating systems of high quality and weathering resistance.
