b'How the Silverson WorksThe advantages of Silversons high shear rotor/stator mixer over simple conventional stirrers or agitators stem from the multistage mixing/shearing action as materials are drawn through the specially designed Silverson workhead - the heart of every machine. Stage 1 The high-speed rotation of the rotor blades within the precision-machined mixing workhead exerts a powerful suction, drawing liquid and solid materials upwards from the bottom of the vessel and into the centre of the workhead.Stage 2Centrifugal force then drives the materials towards the periphery of the workhead where they are subjected to a milling action in the precision clearance between the ends of the rotor blades and the inner wall of the stator.Stage 3This is followed by intense hydraulic shear as the materials are forced, at high velocity, out through the perforations in the statorand circulated into the main body of the mix. Stage 4The materials expelled from the head are projected radially at high speed towards the sides of the mixing vessel. At the same time, fresh material is continually drawn into the workhead, maintaining the mixing cycle. The effect of the horizontal (radial) expulsion and suction into the head is to set up a circulation pattern that minimises aeration caused by disturbance of the liquids surface.5 High Speed High Shear Mixers'
