High Speed High Shear Mixers

The Silverson Principle For over 75 years Silverson has specialised in the manufacture of quality high shear mixers for processing and manufacturing industries worldwide. With customers in over 150 countries, and serving industries as diverse as food, pharmaceuticals, cosmetics, luboils and petrochemicals, Silverson has become the world leader in the field of high shear mixing. Time after time, companies specify Silverson mixers as the “standard” equipment for their manufacturing process. The key to this success is based on the professionalism and commitment Silverson shows to each of its customer’s...

Why Silverson? Speed The exceptionally rapid Silverson mixing action substantially reduces process times compared with conventional agitators and mixers and can reduce mixing times by up to 90%. Versatility The advantage of the Silverson approach to mixing is that any one machine can perform the duties that in the past may have required several different pieces of process equipment. This unrivalled versatility allows any machine to perform the widest range of mixing applications: -  Blending - A homogeneous product is rapidly produced when blending liquids of similar or greatly varying viscosities,...

How the Silverson Works The advantages of Silverson’s 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. The high-speed rotation of the rotor blades within the precisionmachined 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. Centrifugal force then drives the materials towards the periphery of the workhead where they...

Interchangeable Heads and Screens A comprehensive range of workheads and screens is available for all Silverson rotor/stator 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 This is the most versatile of all the heads, giving an exceptionally vigorous mixing action....

Laboratory Scale Mixers Silverson Laboratory mixers are suitable for the widest range of applications - mixing, emulsifying, homogenising, disintegrating and dissolving - with an efficiency and flexibility unmatched by other machines. With a capacity from 1ml up to 12 litres and the ability to mix in-line with flow rates up to 20 litres/minute, they offer excellent reproducibility when scaling up and provide an accurate means of forecasting the performance of larger Silverson machines under full-scale working conditions.

Laboratory Mixers L5 Series Silverson L5 Series mixers are ideal for all routine laboratory work, research and development, QA analysis and small scale production in all industries. L5M-A The multifunctional L5M-A features a powerful 0.75kW (1hp) motor and touch pad control with digital tachometer, programmable integral timer and amperage display, all accessed via the Mode button. The unit can be supplied with a “Data Logger” program, allowing monitoring of speed and power draw over time. This level of instrumentation is invaluable for applications where process validation and reproducibility...

Mixing Assemblies Standard Assembly (Two Arm) The L5M-A is supplied complete with a General Purpose Disintegrating Head, Square Hole High Shear Screen, Standard Emulsor Screen and Axial Flow Head. Slotted Disintegrating Heads, Fine Emulsor Screen, Pump Heads and other special heads are available as optional extras. Capacity - depending on viscosity - up to 12 litres. Mixing unit dimensions length 290mm (11 1⁄2”), width 57mm (2 1⁄4”). Tubular Mixing Assemblies A series of interchangeable tubular mixing units suitable for use in narrownecked containers are available, with capacities from 1 - 500ml...

Laboratory Mixers In-Line Mixing Assembly The In-Line assembly fits onto the model L5 Series Laboratory range and converts it into an In-Line mixer/homogeniser. The centrifugal action of the rotor in the high shear rotor/stator workhead generates a non-positive pumping action which gives a throughput on low viscosity liquids of approximately 20 litres/ minute, reducing as the viscosity increases. The In-Line assembly is suitable for use at atmospheric pressure only. It is not recommended for use on abrasive, corrosive or flammable materials. Specialised Mixers Model L2/Air (Compressed Air) Suitable...

Pilot Scale Mixers AX Series This series of mixers is designed for small-scale production in pilot plants, research institutes, hospital pharmacies, etc. Light and easily operated, AX series models have a capacity of up to 50 litres. Model AX/Air controls and is compatible with an intrinsically safe compressed Silverson’s “DataLogger” system. motor. TEFC, Flameproof/ATEX Rated and stainless steel motors Flameproof/ATEX Rated areas. Powerful 0.75kW (1 hp) 220volt single phase motor (110 volt optional) 50/60 Hz. Speed Control Infinitely variable speed control. Nominal maximum The Model AX3 features...
