Description
The Rometa colour dosing unit automatically weighs and doses concrete pigments in automatic production plants. Each colour is stored in its own hopper, and the system delivers the exact dose to the aggregate line for every batch.
How it works: the operator sets the dose for each colour from the plant control cabin. The weighing cart travels under each colour hopper, where the electromagnetic feeder discharges pigment until the load cells register the set weight. Once dosing is complete, the cart moves to the aggregate belt or skip and discharges the pigment there, so it reaches the mixer together with the aggregates.
