A big bag storage silo is supplied for the storage of big bag raw materials, into which the entire contents can be poured. By matching the silo contents of 1,900 litres – 6,000 litres to the daily requirements, supply can be done during the day shift, thereby reducing the number of full-time employees required. Supply is carried out by means of a big-bag hoist and, if the height is limited, by means of an unloading station with connected plug conveying. The INO discharge system ensures that the products can be dosed from the silos safely and accurately.
