High Pressure Grinding Rolls (HPGR) is rarely considered as lateritic bauxites are too soft to warrant this technology. Only for hard diasporitic bauxite, where digestion feed sizes of P80 -75 µm are required would it ever be considered. Rod and ball mills can readily handle bauxite on account of its very soft nature. However, it is the
The results show that Equation (3) is a particularly suitable model for describing the bauxite grinding in a ball mill as indicated by the high R2 values; in all cases R2 (adj.) values were higher than 0.988. Based on the grinding rate constant K, it is confirmed that the grinding rate is dependent upon the particle size and the amount of ...
This paper presents grindability of the Kokaksu (Zonguldak) bauxite crushed below -3.35 mm in a stirred mill. It was established that the operating parameters of the stirred mill such as the ball ...
The Bond ball mill grindability test is run in a laboratory until a circulating load of 250% is developed. ... Mucsi, G., Solymár, K., 2005. Optimization of bauxite grinding by means of empirical ...
In the present study bauxite ore of hardness 1-3, specific gravity 2–2.5 has been taken for grinding tests in a ball mill. The experiments were conducted for three feed (ore) sizes …

Morrison and …
The selective grinding in vibration mill for bauxite whose components ratio in fraction of w(Al 2O 3)/w(SiO 2)=4.4 was investigated via tests.
In this study, bauxite samples were grinded to ultrafine size (~5 µm) by a laboratory scale stirred mill and its performance was compared with a laboratory scale conventional ball …
the grinding products are better described by the RR model [24, 27, 28]. Over the past decades, the most popular mathematical models used for the optimization of energy consumption in grinding mills are phenomenological grinding kinetics models based on population balance considerations [22]. Population balance modeling which is based on
