Metering system for dry pigment processing

Dry-wet metering system TFW is a wet/dry system that is used to fluidize the mixture of powdered pigments and water.

Once the powders and water are mixed, the mixture or “slurry” is then pumped directly into the mixer or into waiting hoppers until the concrete mixer is ready. The system can be placed up to 100 m from the mixing plant.
