Our process solutions

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.
