The Bond grindability test is performed in a standard Bond ball mill, dimensions DxL=305x305 mm and a speed revolution of 70 min −1. The mill is filled with balls with a diameter of to mm, and has a total weight of kg. This test uses dry grinding in a closed cycle until a stable circulating load of 250% is established. Bond ...

Abstract. The present paper deals with the grindability experimental results of an Australian bauxite sample in the Universal Hardgrove mill, the Universal Bond ball mill and the heat insulated Bond Rod Mill in the temperature range from 20 up to 80 °C. As previously observed the grindability of the bauxite has improved at elevated temperature.

The ability to simulate the Bond work index test also allows examination of truncated ball mill feed size distributions on the work index. For grinding circuits where the feed to a ball mill is sent directly to the classifier and the cyclone underflow feeds the ball mill (see Figure ), a question arises as to whether this practice will alter the ball mill work index (BW i) of the material ...

The ball mill grindability test is used for describing ore hardness and it is so widespread that the Bond Work Index generated from the test is often referred to as an ore characteristic. The ore resistance to grinding and energy consumption can be expressed using the work index and Bond's Third Theory. The Bond Third Theory method is widely ...
