 The liquid components are pumped via tangential nozzles (1) from the batch tank to the acceleration chamber (2). The shear rotor (3), acting like a liquid ring pump, accelerates the suspension creating a vacuum in the acceleration chamber (2). The solids are metered from the above hopper via a rotary valve (4). The vacuum in this chamber, as indicated by the vacuum gauge (5), causes that the capillary air in the solid agglomerates expand. Agglomerates are broken up by internal gas expansion.
The cutting rotor (6), which is part of the shear rotor, boosts the distribution of the solid particles. These finely dispersed solid particles are conveyed into the acceleration chamber (2). A large liquid surface is formed by the high product flow rate.
The mixing and wetting of the particles occurs in the long compression zone. The pressure increases from the vacuum in the acceleration chamber (2) to atmospheric pressure at the free outlet (7). This pressure gradient increases wetting of the particles by forcing the liquid into the capillary paths in the agglomerates.
