The Tower mill is a vertical stirred mill using steel balls or pebble grinding media. This device is designed for fine grinding at significant power savings when compared to conventional tumbling mills. This paper describes the machine and its operation, application, and performance for wet grinding.

Their operational range is given as 400–30 micron [9,10], and energy saving relative to ball milling application is achievable. SMD has been in use since 1998 for the production of <15 m particles. The mill also has vertical arrangement. VXP Mill is a product of FL company and is vertically oriented stirred media mill.

Tower – Main structure that holds the windmill. Cap – Wooden roof on top of the tower that houses wind shaft and sail wheel. It can rotate so that it can catch more wind force. Sail – Wooden wind-catching structure made with 4 to 8 blades. Stock – Main support of sails between frame of the sail and windmill cap.

Vertical stirred mills have been widely applied in the minerals industry, due to its greater efficiency in comparison with conventional tumbling mills. In this context, the agitator liner wear plays an important role in maintenance planning and operational costs. In this paper, we use the discrete element method (DEM) wear simulation to evaluate the …

A. Main features of vertical wet stirring mill (tower mill) 1. The tower mill has strong fine grinding ability and can grind materials to 1μm or finer; 2. The vertical ball mill is energy-saving, which is more than 50% energy-saving compared with the horizontal ball mill; 3. The efficiency is more than 10 times that of the horizontal ball mill; 4.

The Japanese Tower Mill was the first vertical grinding mill to be used in the mining industry (Stief et al., 1987). The Tower Mill® is now produced by Nippon-Eirich. The Vertimill™ is a modified version of the Tower Mill® and it is developed by , Inc. The Vertimill™ and the Tower Mill® have similar design configurations.

1. Introduction1.1. Fine grinding in the mining industry. It has been estimated that approximately 2% of the world's energy usage is applied to mineral comminution, and around a quarter of this is used specifically in metalliferous ore grinding [1] where it is typically the most energy intensive set of operations [2].The purpose of comminution in …

This equipment is predominantly a wet mill. The stirred Tower Mill (Figure 1) was introduced in the United States in 1979 to comminute limestone and has proved to provide a means of fine size comminution where the tumbling ball mill becomes inefficient (Stief, et al., 1987). Figure 1: Tower Mill (Eirich, 2014) MATERIALS AND METHODS

One comment that I did not see here is the potential for differential grinding, especially in vertical mills, but also in ball mills. That is when inter-grinding different materials, the softer materials tend to be ground finer. In air swept vertical mills, this can leave a higher quantity of the harder to grind material in the mill.
