Our know how Our experience

Additive manufacturing

In the developing world of additive manufacturing, the particle size distribution of the metal particles is crucial to ensure a high quality end product in Selective Laser Melting and other techniques.

Starting with atomised metal powder particles, British Rema classifiers are used to generate ideal particle size distributions and our blenders are well-suited for creating homogenous mixes of blended powders.

On a larger scale, British Rema has designed inerting systems and supplied classifiers into industrial ball milling systems processing highly explosive aluminium powders, including detailed ignition hazard assessments and protective instrumentation and control systems.


Integrated into the supply chains of both military and mainstream aircraft programmes, our team at British Rema are world-renowned experts in the contract processing of thermoplastic polymers with particular focus on the aerospace industry.

Used in some of the most critical aircraft parts, consistently achieving precision particle size distribution ensures perfect melt characteristics and flawless output.

Our contract powder processing business is fully focused on quality and compliance, and is subject to regular customer audits.

In addition, we design and lease equipment to overseas customers on a long-term basis as well as providing operator training and full support – all to provide a robust processing solution for manufacturers in this highly-regulated sector.


Supplying and maintaining equipment alongside contract processing our customers’ materials, the agri-food and agrochemical sectors are served by all three British Rema divisions.

We have designed and supplied rotary equipment ranging from small, two metre, two-pier vessels for simple mixing and drying processes in fertiliser plants, up to a 160 tonnes per hour, 25m long steam-tube dryer, using specialist steels and bespoke welding protocols for drying rapeseed flake. We then maintain this equipment during its entire working life.

At the same time, in our powder processing division we regularly micronise fertiliser components to create the optimum particle size for subsequent homogenous blending and product efficacy.


As specialists in the maintenance of industrial rotary vessels, our rotary engineering division’s reputation was originally built in the cement industry in the 1970s.

Analysing kiln alignment and ovality, refurbishing tyres and rollers and, when required, replacing entire kiln sections, we have worked with global cement groups and independents across Europe, Russia/CIS and into Africa and Asia.

Previous projects have included the design and replacement of an 8m diameter tangential girth gear on a 6m diameter rotary kiln and the changing of multiple kiln sections simultaneously.

Our process equipment division is a long-standing supplier of ball mills and classifiers, commonly found in cement plants and we are regularly called upon to give independent expert advice on kiln performance issues as we have no affiliation with any of the OEMs.


In such a diverse and demanding sector – all three divisions of British Rema can help you achieve control and consistency when processing chemicals.

We have designed and built equipment from laboratory to commercial-scale to process powdered chemicals effectively and efficiently. Recent projects include blending pigments and dyes to improve colour control and intensity, and micronising ingredients such as phosphorus for fertilisers and sulphur for fungicides to improve yield by protecting grapevines from mildew.

Our contract powder processing division has a wealth of experience toll milling and classifying organic materials such as structural polymers, resins and waxes, many of which traditionally require cryogenic milling, plus inorganic materials, minerals and ores, even extremely hard substances such as metal oxides, carbides and nitrides.

In addition, our rotary engineering division is experienced in maintaining and repairing industrial-scale kilns, dryers and similar rotary equipment for processing ores, cements, minerals and chars.  


Due to the fast-paced increase in global population, the production of safe and sustainable food resources has become one of the world’s most pressing challenges.

Our food grade milling and mixing equipment is designed for R&D or commercial production of powdered ingredients. Our customers are successfully using air classifiers to enrich the protein content of dried pulses and grains. We also have experience in blending proteins and nutritional supplements.

We’ve designed, installed and maintain rotary mixing and drying equipment for producing many high-quality bulk food products including sugar, rice, grains and seeds.

Our powder processing team offers support to our other divisions and potential clients in the form of trials to determine viability, capabilities, optimum particle sizes and production rates of food products.


Having supplied micronising production plants to the European sites of major pharmaceutical companies, our team at British Rema is familiar with the regulations, including GMP, IQ, OQ, PQ protocols and other relevant requirements.

Plant specifications have included inert atmospheres, contained feed and discharge, and all the relevant instrumentation and control systems.

Our contract powder processing division regularly micronises thermoplastic polymers for use in medical implants and dental applications, and so complies with the extensive quality controls and validation procedures that these sectors require.


With a long-standing heritage in the mining and mineral industry, we have installed plants in many countries across the world and have mills and classifiers that are well suited to this environment.

Recent projects have included a turnkey ball mill plant for grinding and screening aluminium hydroxide at 6 tonnes per hour and a classifying plant for calcined gypsum, and in our contract powder processing facility we handle specialist abrasive materials and minerals such as zircon flour and cryolite.

Waste processing/recycling

Alongside helping our customers combat the global food challenges we face today, British Rema is also focused on supporting customers involved in the processing of waste materials.

We’ve supplied equipment designed to extract lime from waste streams for use in agricultural soil enrichment treatments and built equipment for processing fly ash to achieve the appropriate standard for use in concrete and grout products. Another example is the separation of fine grades of glass for use in coatings, paints and shot blasting.

Our powder processing division has been involved in determining the optimum particle distribution for biomass feedstocks, converting granules into powders to allow reprocessing of polymers and glass, and adding value to waste products such as tyre char, to ensure they are viable as a potential feedstock.

Also, our rotary engineering division ensures the optimal operation of incineration drums for the vital processing of hospital and other hazardous waste products as well as supplying and maintaining vessels for recycling waste into fibreboard and processing sewage to be used as fertiliser or alternative fuels.
