to the ineficiency of ball mills for fine grind applications. The difficulty encountered in fine grinding is the increased resistance to comminute small particles compared to coarse particles. As a result, increased energy inputs are necessary to raise the number of collisional events in a mill ... Figure 2.10 Attritor mill (Szegvari & Yang ...
"stirred ball mill." A useful and simple equation describing the grinding momentum is M x V (mass x velocity), which enables us to see how the Attritor fits into the family of mills. For example, ball mills use large media, normally ½" or larger, and run at a low (10-50) rpm. The other mills, such as sand, bead
The attritor ball mill, also known as stirred ball mill, is a kind of vertical ball mill. It can be divided into dry type and wet type, suitable for grinding a variety of materials, such as industrial ceramics, fireproof materials, silicate materials, metal powder, ores, etc. It is equipped with an agitation system inside the grinding cylinder.
Attritors or stirred ball mills are a simple and effective method of grinding and dispersing fine and homogenous material quickly. The Attritor can operate wet or dry, introduce inert atmospheres, operate at controlled temperatures, and vary grinding speed. Results are repeatable from one grind (batch) to another so the attritor is ideal for ...

B02C17/00 — Disintegrating by tumbling mills, i.e. mills having a container charged with the material to be disintegrated with or without special disintegrating members such as pebbles or balls B02C17/16 — Mills in which a fixed container houses stirring means tumbling the charge
Mechanical alloying for commercial production is carried out in ball mills of up to 3000 lb capacity (Fig. 5). The milling time decreases with an increase in the energy of the mill. For example, a process that takes only a few minutes in the SPEX mill can take hours in an attritor and a few days in a commercial mill.

The Attritor is often referred to generically as an "internally agitated high energy media (ball) mill." Attritors work ten times faster than ball mills, and are advantageous because they offer simple operation, rugged construction, and a compact design. Advantages of Using an Attritor. Ten times faster than ball mills.
An attritor mill, also known as a stirred ball mill, is a type of milling equipment used for grinding and mixing materials. It is commonly used in the production of ceramics, paints, and other materials that require fine grinding. How Does an Attritor Mill Work? Attritor mills work on the principle of agitated grinding.
The present model focuses on experiments using an attritor mill, model 01HD by Union Process. In this mill, milling balls are agitated by a steel impeller rotating at a designated speed. In the experiments, the impeller was set to rotate at 400 rpm. The attritor mill contains a built-in data acquisition unit by Baldor.

For all the attritor mill parts – impeller, vessel and media balls – the material properties of the stainless steel were selected. As typical in the DEM simulations an artificial value for the Young's modulus is considered to reduce the computational time, however as demonstrated by [ 31 ] this does not impact significantly the results.
