Attrition Mills

 · Batch attrition mills can process high-density material, such as tungsten carbide, as well as viscous materials, and are suitable for dry grinding and for processing dispersion-strengthened metals. Continuous attrition mills, best suited for large production output, consist of a tall, narrow, jacketed chamber through which a well-remixed slurry ...

Advice from Union Process on finding the right grinding ...

 · Customers can choose from different types of mills for these applications: ball, attrition, sand, or small-media mills. Different mills suit different processing requirements, Schilling explains. An important factor in the process of selecting a grinding mill is the feed material.

Visual Encyclopedia of Chemical Engineering

Attrition mills are used for fine grinding operations in the production of spices (pepper, cinnamon, paprika), food (peanuts, grain, cereal), fibers (chips, cork, cellulose) and blendings (face powders, insecticides). The pictures below show pepper and cinnamon, finished products from attrition milling.

Union Process Attritor Mill. The attritor mill is a wet grinding attrition mill. It differs from conventional ball mills as it uses much smaller media with diameter less than 5mm, leading to greater media-material contact area. Additionally, the attritor mill works at a higher rotation speed up to SPEED.

Milling process services from Custom Processing Services

The shearing forces (tearing apart), impacting (crushing by outside forces), and attrition (tearing and crushing each other apart) create particle distributions in the nanometer or sub-micron ranges. The media in autogenous grinding can be large pieces of material, so this technique is milling by attrition (self-grinding), not by impact.
