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.

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.

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.

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.

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.

Mixer Options

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 of up 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.

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.

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.

General Purpose Disintegrating Head

Used for a wide range of applications, this head will give the greatest throughput. Suitable for the blending of liquids of similar or greatly varying viscosities, its uses include the disintegration of solid and semi-solid materials.

Square Hole High Shear Screen^TM

The configuration and fine internal tolerances of this stator provide exceptionally high shear rates which are ideal for the rapid size reduction of soluble and insoluble granular solids. It is also suitable for the preparation of emulsions, gels and thickeners and fine collodial suspensions.

Slotted Disintegrating Head

For the disintegration of fibrous materials such as animal and vegetable tissue, as well as the disintegration and solubilisation of “elastic” materials such as rubbers and polymers.

Emulsor Screens

These screens are suitable for liquid/liquid preparations and are especially useful for all emulsions. Emulsor screens are available in fine or medium perforations.
