These mills are known commercially as Stirred Media Detritor Mills. Tower or Vertimill mills are generally of two types, namely 1. Low Speed Mills 2. High Speed Mills The velocity of rotation of the low speed mills seldom exceeds 3 m/s at the tip end while the tips of high speed mills are designed to revolve at about 15 m/s.

AG or SAG mill, intermediate grinding to a ball mill or tower mill, and fine grinding to a stirred mill such as an Isamill or Stirred Media Detritor (SMD). Of course, various exceptions to these typical values can be found. In fine grinding, a material with an F80 of less than 100 lm is comminuted to a P80 of 7 to 30 lm. (P80s of

The SMD is a fluidized media mill which means, the impeller speed is high enough to distribute the media throughout the slurry regardless of media density, forcing particle and media contact. Largest SMD in the world. The largest SMD in the world, a 1.1 MW device, has recently been commissioned in South Africa in a platinum regrind application.

Stirred Media Detritor (SMD) is a fluidized, vertical stirred mill designed for optimum grinding efficiency for fine and ultrafine grinding products. SMDs have the capacity to operate continuously at full load power draw with no steel contamination of the product. They are suitable for both open- and closed-circuit operation.

The power intensity of the IsaMill is 400 kW/m 3 compared to 150 kW/m 3 of the SMD mill, 19 kW/m 3 of the ball mill and 4 kW/m 3 for the Verti-Tower mill (Xstrata Technology 2010).
