Attrition Mill for Toll Processing The Mikro® UMP Attrition Millis a high-speed cutting mill designed for the fine size reduction of plastics, waxes, and fibrous materials that do not respond well to other forms of impact milling. It is designed to grind heat-sensitive and soft materials without liquid nitrogen or conditioned air.

The ATTRIMILL is an attrition mill (or kinetic mill) principally used for plastics or fibrous products. It combines three physical principles that generate efficient ultra-fine grinding. The auto-comminution of the particles generated by the upward air spiral,

An attrition mill comprising a grinding chamber (1), an axial impeller (10), a chamber inlet (3) for admitting coarse particles and a separator comprising a chamber outlet (6) through which fine particles exit from the chamber. The mill is characterized in that a classification as between coarse and fine particles is performed in the mill upstream of the separator.

Attritors can generally grind to finer size particle size range than impact or hammer mills by combining the advantages of cryogenic temperatures with both impact and shear forces inherent to high energy internally agitated ball mills.

· Attrition - arising from particles scraping against one another or rubbing action (colloidal mill, roller mill). Particle Size 1-50 µm · Impact and Attrition – ball mill, fluid energy mill, Particle Size 1-2,000 µm. Advantage of size reduction · Content uniformity · Uniform flow

In ball mill, size reduction is done by both impact and attrition of particles. Rod mill is similar to ball mills but it uses long rods for grinding media. Autogenous mill is a self-grinding mill which is used in breakage of larger rocks.

Attrition Grinder The batch grinding tests were made in the Bureau's 10-inch-diameter attrition grinder, which is described in detail in an earlier report. The unit, as assembled for batch testing, is shown in figure 1. The grinder consists of a rotor and stator fabricated of carbon steel and assembled in a vertical, cylindrical container.

Attrition mills can operate in either batch or continuous mode and suit harder-to-grind material such as metal powders, metal carbides and glass frits. Their shaft speed runs from 75–500 rpm and media generally range in size from 5–13 mm. Feed material can be as coarse as 1/2 in., while end product size can be as fine as 2–3 microns if ...

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.

MIKRONS ATTRITOR. MIKRONS® ATTRITORS are available in broad ranges from traditional attrition mill type to the latest wet & dry grinding type, circulation type attritors. MIKRONS® is the brand name of the range of process equipments manufactured by this group comprising of MICROMERITICS ENGINEERS Pvt. LTD & MICROPARTICLE ENGINEERS (P) LTD.

Attrition mills generally have high pumping rates. Usually, the contents of the holding tank are passed through the system at a rate of ten times per hour. One advantage of the circulation attrition mill is that large quantities of material can be handled with a minimum investment in grinding medium and equipment.
