High Shear In-Line Mixers

High Shear In-Line Mixers

Silverson High Shear mixers are supremely efficient and rapid in operation and are capable of reducing mixing times by up to 90%. The action of any Silverson In-Line mixer can be modified with the use of rapidly interchangeable workheads. This enables any machine to mix, emulsify, homogenise, solubilise, suspend, disperse and disintegrate solids.

Features:

  • Aeration free
  • Self-pumping
  • No bypassing
  • Interchangeable workheads
  • Hygienic construction
  • Easy maintenance
  • Lower power requirements
  • Eliminates agglomerates and fish eyes
  • Creates stable emulsions and suspensions
  • Reduces particle size
  • Rapidly dissolves solids
  • Accelerates reactions

How It Works

Silverson's line of high shear In-Line mixers offers a great many advantages to the processor - speed, versatility, self-pumping, aeration-free, guaranteed efficiency. At the heart of every mixer is Silverson's high performance rotor/stator workhead.

High Shear In-Line Mixers
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 into the rotor/stator assembly.

High Shear In-Line Mixers
Stage 2

Centrifugal force then drives the 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.

High Shear In-Line Mixers
Stage 3

This is followed by intense hydraulic shear as the materials are forced, at high velocity, out through the perforations in the stator, then through the machine outlet and along the pipework. At the same time, fresh materials are continually drawn into the workhead, maintaining the mixing and pumping cycle.

Interchangeable Workheads

Workheads

A comprehensive range of workheads and screens is available for all Silverson high shear mixers. These easily interchangeable workheads offer great versatility by allowing any machine to be adapted to perform a wide range of mixing operations including emulsifying, homogenising, disintegrating, dissolving, dispersing, blending, particle size reduction and de-agglomerating. Changing from one head or screen to another is quick and simple.

Technical Information

Capacity
Self-pumping throughputs of 20 to 300,000 litres/hr.
No Bypassing
Product cannot bypass the precision rotor/stator workhead.
Interchangeable Workheads
Single stage rotor/stator configurations as standard. For those applications that require greater shear, interchangeable multistage configurations can be used.
Materials of Construction
Product contact parts in 316L stainless steel. Special materials available on request.
Motor Specifications
​TEFV and ATEX approved Flameproof motors are available as standard. Inverter rated, stainless steel and other motors are available as optional extras.
Inlet and Outlet Connections
All sanitary or flange fittings available upon request (i.e., Tri-Clamp, ASA, DIN, etc). All Silverson In-Line Mixers are designed for cleaning-in-place (CIP and SIP).

Mixer Options

In-Line General Duty In-Line Mixers - US
General Duty In-Line Mixers

Silverson offers a range of In-Line mixers suitable for hazardous and aggressive chemical service. These robust mixers require minimal maintenance and provide some of the highest rotor tip speeds and shear rates in the industry. Self-pumping capacities from 20 to 20,000 litres per hour.

Jacketed units are available for temperature sensitive products and construction in non-standard materials such as hastelloy, titanium and hardened steels can be offered.

In-Line Multistage In-Line Mixer - UK
Multistage In-Line Mixer


The Multistage In-Line Mixer quadruples a number of shearing actions per revolution of the rotor, resulting in substantially faster mixing times and also increasing the number of products that can be processed in a single pass.
