Abstract
The invention is directed to a method of and a system for mixing batches of a flowable medium, especially of hydrocarbons used as base materials for said media and of additives to be admixed thereto. In the mixing operation, the base materials and optionally additives are weighed in a primary weighing section capable of holding a complete batch to form the base medium. Independently thereof, additives, amounting to minor fractions of the batch, are weighed out in at least one precision weighing section. The weighed-out additive fractions are then admixed to the weighed-out base medium.
