Bottom Entry Mixers - How It Works

The advantages of Silverson’s Bottom Entry 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 exerts a powerful suction, drawing liquid and solid materials downwards into the center of the workhead.

Stage 2

Centrifugal force then drives the materials towards the periphery of the workhead where they are milled in the clearance between the rotor and the stator.

Stage 3

The materials are subjected to intense hydraulic shear as they are forced out through the stator and projected radially at high speed towards the sides of the mixing vessel. Fresh material is simultaneously drawn into the workhead, maintaining the mixing cycle.
