An improved system for mixing a dry particulate matter with a liquid. The system mixes the dry particles with a liquid to form a liquid mixture containing unwetted particles. The liquid mixture is placed in a settling tank so that the unwetted particles gravitate toward the bottom of the tank. The unwetted particles are withdrawn from the tank bottom and are pumped through a mixer which reduces the size of the unwetted particles and redirects the stream back into the tank. This process is manually or automatically reiterated until the liquid mixture becomes a homogeneous wetted material. By cycling the unwetted particles which are separated from the bulk of the liquid mixture, the system efficiently concentrates on the unprocessed and less processed portions of the liquid mixture. After processing is complete, the homogeneous wetted material can be discharged into a holding tank for distribution.
