Mangra, S.A. designs and builds Blending Plants for solids and liquids fertilizers under continuous production basis.  We can manage from 20 to 150 T/h with unlimited number of hoppers.



The hoppers are designed for pale loaders or forklifts loading. After loading the hoppers, each product is identified and after introducing the required formulation in the controlling PC, the system starts the production automatically and the screwdrivers and bucket elevators will be switched on until the total amount of required tons is finished.

The weighing system works by deducting the extracted product quantity trough the screwdrivers or conveyor belts from each hopper. Thus, the system controls the screwdrivers or belt’s speed in order to achieve the right percentage of each component according to the formula.
