The SD Dry Grinding Attritors can be operated in both continuous and batch processing applications. In the continuous operation, the material is fed into the vessel at the top. It then migrates through the agitating media bed where it is processed to a desired particle size and is discharged through metering bar grids at the bottom of the tank.

Andrew Szegvari in 1945, Attritor technology grew to become the basis for Union Process, Inc., an independent, familyowned American company founded in Akron, Ohio. Today, Attritors are considered to be the most efficient grinding/dispersing systems and are used in scores of industries and research laboratories worldwide. More recently,
velocity), which enables us to see how the Attritor fits into the family of mills. For example, ball mills use large media, normally 1/2"or larger, and run at a low (1050) rpm. The other mills, such as sand, bead, and horizontal, use smaller media from to 2mm, but run at a very high rpm (roughly ).

to a SPEX mill, and to a commercial ball mill. We have investigated the effect of using differently sized balls on attritor media dynamics, with the longrange purpose of im COOK, Graduate Research Assistant, and COURTNEY, Professor and Chair, are with the Department of Metallurgical and
An attritor mill consists of a vertical stationary tank filled with a rotating shaft on which multiple horizontal arms are connected. The tank is filled with lignocellulosic biomass, grinding balls, and liquid. ... Planetary ball mills are substantially smaller than other ball mills and are commonly used in laboratories to grind sample ...
includes the separation tank, mill recirculating pump, mill product tank, hydrocyclone, hydrocyclone feed pump and all necessary controls. Due to the CL Attritor's high efficiency, the power consumption for this mill is 50% less compared to conventional ball mills of a similar size. This results in substantially lower operating costs.
Manufacturer and distributor of ball, air swept vibrating ball and attritor stirred ball wet grinding mills for mineral, chemical and commercial applications. Features vary depending upon model, including removable steel grates, static screen boxes, heavy duty bearings, builtin air sweep injectors, carbon steel chambers and rotating arms.
This modern high output fine grinding machine employees the wellknown principle of grinding dispersing with agitated balls. The materials take shorter grinding time in Attritor than conventional Ball Mill. The Attritor is often referred to as a agitated ball mill. We have emerged as one of the leading manufacturers, exporters and suppliers of a wide range of Attritor Mills.

The introduction of lower temperatures during cryomilling curbs recrystallization and embrittles materials so they can be fractured more easily with mechanical milling. Cryogenic grinding is often performed in impact mills and hammer mills, but the use of an internally agitated ball mill, like an Attritor, can provide additional benefits.
Another difference between ball mills and attritor mills is the milling atmosphere. In ball mills, the materials to be ground are placed in a container that is filled with air or an inert gas. On the other hand, attritor mills are operated under a controlled atmosphere. The materials are placed in the mill along with the grinding media and a ...
Grinding time is related to media diameter and agitator speed via: T = KD 2 /N 1/2. where T is the grinding time to reach a certain median particle size, K is a constant that depends upon the material being processed, the type of media and the particular mill being used, D is the diameter of the media, and N is the shaft rpm. This equation shows that total grinding time is directly ...
The Attritor is often referred to generically as a "stirred ball mill." The operation of an Attritor is simple and effective.
