The dosing powder is stored in a hopper with a maximum volume of 2,000 L, which can also be equipped with a dust filter. The hopper discharge unit and the flexible screw conveyor optimize the performance of the metering unit and ensure its accuracy.

The volumetric metering units, combined with a weighing system, guarantee a higher accuracy of dosing. This equipment is designed to be paired with a preparation tank of lime milk slurry or activated carbon mix .

The screw feeder is ideal for discharging smaller quantities of product, such as hydrated lime, quick lime and activated carbon, and is advantageous due to its high level of accuracy.
