Batch Mixers

Experience more than just mixing – Silverson High Shear Batch Mixers emulsify, homogenize, solubilize, suspend, disperse, and disintegrate solids with unparalleled precision. Each mixer, with its precision-engineered Silverson rotor/stator workhead, far outperforms conventional mixers, cutting processing times by up to 90% while enhancing product quality, consistency, and process efficiency.

Why Choose a Silverson High Shear Batch Mixer?

  • Achieve precise processing from 1 to 8,000 gallons
  • Eliminate fish eyes and agglomerates
  • Create stable emulsions and suspensions effortlessly
  • Reduce particle size for optimal texture and consistency
  • Rapidly dissolve solids
  • Boost reaction rates for faster production cycles

How It Works

The advantages of Silverson’s high shear rotor/stator batch 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 center of the workhead.

Stage 2

Centrifugal force then drives materials towards the periphery of the workhead where they are subjected to a milling action in the precision-machined clearance between the ends of the rotor blades and the inner wall of the stator.

Stage 3

This is followed by intense hydraulic shear as the materials are forced, at high velocity, out through the perforations in the stator and circulated into the main body of the mix.

Stage 4

The 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 minimizes aeration caused by the disturbance of the liquid’s surface.
