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.

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.

They had the following initial specifications of design: a 2-liter working capacity, speed of rotation of the central shaft to 500 rpm, hole generation under the recipient container, and conditions...

Cover seals can be provided for conditions where dust control is desired, or where grinding must be done under a closed inert gas system. Torque meter is available including torque and speed sensor read-out. Media discharge valves can also be installed. Variable frequency drives and controls are available.

In this work the γ - to α-Al 2 O 3 phase transformation induced by mechanical milling was investigated as a function of the bead size for two laboratory scale high-energy mills: a planetary ball mill and an attritor mill. The alumina was texturally characterised, before and after milling, by Scanning Electron Microscopy (SEM) …

In our mill, the flow rate of cooling water is varied from 0 to 1500 l h-1, so that we can control the agitating temperature Tp to optimize the rate of solid state reaction. Furthermore, our mill provides a system to control the atmosphere inside the attritor, as shown in Figure 1. Process characterization of the solid state amorphization
