At the PPMA show 2023 you can find Silverson Machines on Stand E20. On the stand will be a range of high shear mixing equipment, from smaller-scale Laboratory mixers to full scale production mixers such as the Flashmix powder/liquid mixer.

Silverson Machines has the largest capacity range from a single manufacturer and have been helped customers across a range of industries to improve their mixing processes. The extensive range of high shear rotor/stator mixers that Silverson manufactures means that we can help with mixing as little as 1ml, or large volumes of up to 30,000 litres and everything in between.

Visitors to Silverson’s stand will be able to see working examples of Batch, Ultramix and Laboratory mixers including the Verso-UHS-HV. Here is an overview of the products in the Silverson range which will be on the stand.

Other mixers for specialised mixing such as Sealed Units, Multi-stage units and ATEX approved models are available but not mentioned here. For more information on those mixers, please visit the Silverson website.


Laboratory Mixers

For mixing small batches from 1ml up to 12 litres, Silverson has a range of Laboratory mixers suitable for a wide range of mixing processes. All Silverson rotor/stator mixers come with a range of easily interchangeable workheads, which allow one mixer to perform many mixing tasks which would otherwise need several pieces of mixing equipment. Silverson Laboratory mixers can blend, emulsify, homogenise, disintegrate, dissolve and de-agglomerate, and mix in-line with flow rates up to 20 litres/minute using an In-Line mixing assembly. The most popular mixer in the Silverson product range, the L5M-A Laboratory mixer, features touch pad controls and a tachometer, ammeter and programmable timer.

Scaling-up is a relatively simple process as all Silverson laboratory mixers are designed and built to the same tolerances as the production units; comparable rotor tip speed and shear rates across our entire product line allows for easy scale up without the need for reformulating.

In-tank mixers

For in-tank mixing of volumes up to 30,000 litres Silverson supplies in-tank Batch mixer models. Capable of performing all of the same mixing process as Silverson Laboratory mixers, it is possible to reduce mixing times by up to 90% when using high shear Batch mixers as opposed to traditional mixing methods such as stirrers or agitators. Small to medium range Batch mixers can be used on mobile floor stands, further increasing their versatility.

The Silverson Ultramix in-tank mixer is designed for applications that are beyond the capabilities of a conventional agitator or stirrer but do not necessarily require the intense high shear of a Silverson rotor/stator mixer. Ideal for rapidly wetting out powders including gums and thickeners, the Ultramix is also ideal for use in vessels with narrow openings. The vigorous mixing action is capable of moving the entire contents of vessels even in difficult shaped containers.

Laboratory-scale In-Line mixing

Silverson will be displaying production-scale In-Line mixers as well as demonstrating working benchtop models such as the Verso-UHS-HV.

The Verso-UHS-HV is a laboratory-scale In-Line mixer designed for mixing high viscosity products. It incorporates the same unique and innovative ‘pumping rotor’ design as the production scale HV In-Line mixers. This substantially increases its self-pumping capacity, allowing it to process products such as gels, creams, sauces and gum solutions on a laboratory scale.

A conversion kit is available allowing the Verso-UHS-HV to be configured as an FMX5 Powder/Liquid mixer. This kit increases the versatility of the machine, allowing one mixer to be used as a Laboratory scale High Viscosity In-Line mixer or Powder/Liquid mixer.

Powder/Liquid mixing

For mixing large quantities of powder, Silverson developed the Flashmix. Unlike many powder/liquid mixers, which use vacuum to pull in powder, the Flashmix literally forces powder into the liquid stream. This not only allows it to disperse and hydrate large volumes of powders, it means it can be used at higher temperatures and with higher viscosity mixes.

The FMX5, the laboratory scale version of the Flashmix, provides a simple, effective and hygienic means of incorporating a wide range of powders into liquids. The unit is suitable for small scale manufacturing and R&D work with a typical batch size of up to 10 litres, depending on viscosity.

These are just a few of the mixer options available in the Silverson product range, you can find more information on additional models, such as Bottom Entry mixers and Pilot Scale Batch mixers, on the Silverson website.
