Solving material processing challenges through drying, milling and separation
We transform complex and overlooked materials into higher-value products using proven drying, milling and separation technology. Atritor systems can dry and mill simultaneously, combining two process stages into one efficient step, with applications across food, chemicals, pharmaceuticals, minerals, construction and innovation sectors.

Atritor Alchemy
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.
