DRY GRINDING ATTRITORS - Union Process
Andrew Szegvari in 1945, Attritor technology grew to become the basis for Union Process, Inc., an independent, family-owned 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,

An attritor mill (1) comprises a grinding chamber (5) and a rotor (7) having a plurality of radial arms (9, 9', 9"). The attritor mill (1) is arranged to grind, mince, triturate or micronize a material to be treated, such as for example urban solid waste, food scraps or more generally the so-called "wet waste", by carrying out the following steps: S1) mixing the material to be treated with ...

Attritor milling differs from ball milling in that the chamber containing the milling medium is stationary and the medium is displaced by a rotating shaft with side arms. According to Szegvari and Yang [ 43 ], attritor milling uses about half as much energy as conventional ball milling to reach the same median size in the milling of chalcopyrite.

Fine Refining Ball Mill – Royal Duyvis Wiener B.V.
Description. The principles of grinding are well established: the pre-ground liquor is pumped through the ball mill's grinding vessel in one or more stages. The refining action is accomplished by a special shaft with agitator arms and diverters rotating in a vertical jacketed grinding tank, which is filled with hardened steel balls. The various layers of grinding elements move in the …

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 in an attrition mill (Fig. 24) is effected by the stirring action of an agitator that has a vertical rotating shaft with horizontal arms. This motion causes a differential movement between the balls and the material being milled, thus providing a substantially higher degree of surface contact than is achieved in tumbler or vibratory mills..
