Solving material processing challenges through drying, milling and separation

We help manufacturers transform complex, variable or overlooked materials into higher-value products through proven drying, milling and classification technology. Atritor technology can dry and mill simultaneously – combining two traditional process stages into one efficient, high-performance step. We work with a huge range of chemical, pharmaceutical, mineral and food materials, providing industrial-scale material processing technology.

in one step

You get out more than you put in

We collaborate with clients to find efficient, application-specific solutions. Drawing on a database of more than 500 material categories and thousands of test results, built over 75 years, we bring detailed insight into material characteristics and performance. The result is better-informed decisions, faster development and more value from every project.

Materials we work with

We design and build tailored solutions to process materials using single or multi-stage operations to ensure the end product meets the desired specifications.

Your material. Engineered

Minerals and industrial materials

Clays, calcium carbonate, limestone, silica gel, iron oxides, pigments

Secondary materials and by-products

Fly ash, coal, hydroxides

Food, nutrition and bio-based materials

What's your material?

Two processes. One powerful step.

Atritor’s combined drying and milling technology turns two traditional stages into one efficient, high-performance process – redefining what material processing can achieve.

Drying

Atritor mills can take materials of up to 98% moisture and dry and mill them simultaneously. Designing a drying process requires recognition of the characteristics of a material, in particular, how it may be adversely affected by heat.

Fine Milling

Typically used to reduce the size of particles in various materials, including minerals, metals, ceramics, and food products. Atritor fine milling processes can generate a mean particle size as small as 20 microns, or less than 5-10 microns with a combination of deagglomeration and milling.

Deagglomeration

Used for breaking down large clusters or agglomerates of particles into smaller, individual particles. Particularly useful when it is essential to have consistent and uniform particle sizes for optimal product performance and quality.

Classifying

When a tightly controlled particle size, distribution or top size is required or where there is a requirement to remove impurities from the raw material. Classification can be an integral part of the process with Atritor air classifier mills.

Prove it before you commit

Our UK production-scale testing facility allows clients to trial materials, validate process requirements and generate performance data before moving into full-scale production.
