Materials & Applications

We design and build tailored solutions to process materials using single or multi-stage operations. Use our handy tool to select your material and see the different processes we can design and build solutions for.

We have a database of over 500 categories of material and 1000s of test results. Accumulated over seventy-five years, they provide detailed insight into the characteristics and performance of materials.

What's your material?

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.

Fly Ash in Concrete

In the construction industry, coal-derived fly ash (CDFA) plays a crucial role. Its applications are diverse, ranging from cement production, serving as a catalyst, soil replacement and use in structural fills. The use of fly ash in concrete represents a substantial part of its consumption in the construction industry.
