High Shear Mixers: The Powerful Solution for Your Mixing Needs
From laboratory to production-scale, Silverson Machines offers an unparalleled range of high shear mixers. Guided by our commitment to innovation, reliability, and customer satisfaction, we are dedicated to equipping you with the optimal mixing solution tailored to your unique requirements.
What is high shear mixing?
High shear mixing is an advanced mixing technique that involves intense mechanical agitation and shearing forces to achieve superior blending, dispersion, and particle size reduction. Unlike conventional mixers or agitators, high shear mixers utilize specialized rotor/stator technology to generate extremely high shear rates, creating a powerful suction effect that continuously draws materials into the high shear zone.
Leveraging this advanced technology, high shear mixers provide remarkable mixing efficiency, enabling:
-
Faster processing times and increased production throughput.
-
Finer and more uniform droplet/particle size distributions.
-
Improved product quality, consistency, and stability across batches.
Silverson high shear mixers are engineered to deliver exceptional mixing performance, combining advanced rotor/stator technology with robust construction and scalable designs.
Comprehensive Range of High Shear Mixers
Engineered with precision and built to last, each Silverson high shear mixer is meticulously crafted to deliver industry-leading mixing performance, seamlessly tackling tasks from small bench-top applications to large-scale production demands.

Mixing Applications
Through years of experience working with high shear mixers in many, many applications, Silverson has gained a wealth of mixing information. Here you will information on applications that benefit from using Silverson Mixing equipment in the Food, Chemical, Cosmetics and Pharmaceutical Industries. Find out how Silverson Mixers are able to overcome common mixing problems, watch ‘How to’ videos (on selected pages) and find the best mixers for each application.

Food
Less waste. Shorter cycles. Sanitary standards that pass audit.
Food manufacturers lose time and raw material to clumping thickeners, unstable emulsions, and inefficient powder hydration. Silverson tackles each challenge fast, while meeting 3-A and EHEDG sanitary standards.
Chemicals
Stable emulsions. Precise particle size. Lower energy use.
Chemical processing demands consistency under abrasive, high-viscosity, and reactive conditions. High shear accelerates reaction rates, eliminates agglomerates, and is designed to scale from R&D to full production with little to no reformulation.
Cosmetic/Toiletries
Consistent formulas. Faster batches. Scale-up that works.
Emulsion stability, scale-up consistency, and uniform dispersion are the problems every cosmetic manufacturer faces. Through controlled shear, high shear mixing delivers stable, repeatable results that scale.
Pharmaceuticals
Precision mixing. Validated results. Batch after batch.
Pharmaceutical manufacturing requires total batch uniformity, repeatable particle size reduction, and equipment validated to FDA, cGMP, and global regulatory standards. Silverson’s Ultra Sanitary range is built for exactly this.
Certifications & Quality Standards
Silverson operates under internationally recognized standards for quality, environmental management, and occupational health and safety. These certifications reflect our commitment to consistent manufacturing, responsible operations, and continuous improvement across all areas of the business.

Scale-Up
Ramp up for production
With over 75 years’ practical experience, Silverson has the expertise and know-how to help you scale up from the laboratory or pilot plant to full production. It’s a critical stage of any process, and it is increasingly seen as a vital factor in decision-making when specifying a new mixer. The demand for ever more accurate scale-up has led to a growing emphasis on scientific research by manufacturers and academics alike.
There are theories and formulas put forward as the key to successful scale-up, but the mixing characteristics of high shear rotor/stator mixers are complex and no single rule can reliably be applied. Rotor tip speed, workhead design, power input, volume turnover, liquid rheology (characteristics of the liquid under shear) and viscosity all affect the end result. Silverson is working in partnership with some of the world’s leading academic research projects for the advancement of high shear mixing technology, and this pioneering work, combined with over 75 years’ practical experience in helping clients with some of the most difficult mixing challenges allows us to offer unrivaled expertise when it comes to scaling up.
Part of the key to our success – and that of our clients – is the accuracy with which we can predict the performance of our production scale mixers based on laboratory trials. There’s no point using a laboratory mixer capable of speeds of 25,000 rpm or more if the results cannot be replicated in production. That’s why our laboratory mixers are designed and built to the same tolerances as our production units; comparable rotor tip speed and shear rates across our entire product line means scalable results, every time.
At Silverson we test our mixers under the most realistic conditions possible…yours
And we’re confident that they can revolutionize your process – improving product quality and consistency and dramatically cutting mixing times – so we challenge you to put us to the test. Call us and we can quickly arrange for a local Technical Representative to visit you and carry out laboratory scale trials on your product. For pilot and production scale applications our trial program allows you to conveniently test a larger mixer at your own facility.
Alternatively you can visit our fully equipped Test Center in East Longmeadow, MA. These are available for the use of all clients and allow you to discuss your application with our experienced in-house technical staff and carry out your testing program. We can replicate many typical process systems and you can test your product on a full range of Silverson high shear mixers – whether on a laboratory scale or full production volumes. We also maintain a state-of-the-art analytical laboratory, allowing immediate on-site analysis of samples during trials.
Whether you are looking to improve your existing process, or want to take advantage of the latest mixing technology in the development of a new product or process, call Silverson – we’ll find the right mixer for you.
