Optimization Of Ball Mills With Liners In Ore Industries

Aug 02, 2019 Exponential increase in the demand of steel all over the world is leading to rapid depletion of the high grade lump iron ore, leaving the low grade iron ore as fines. Hence industries are forced to use low grade iron ore fines by beneficiating it which produces desired high quality ore required for blast furnace. The fines are subjected to the communition like crushers and mills as the ... These variables were investigated in regard to the Itakpe iron ore. A representative sample of 10.5kg of the iron ore was collected and milled, taking appropriate quantities to study the process variables the effect of grinding time, fraction of mill critical speed, media-to-ore ratio and mill filling.

Discrete Event Simulation of an Iron Ore Milling Process

Discrete Event Simulation of an Iron Ore Milling Process

ore treated was very difficult to mill. In the first two days, the mill experienced numerous power dips (overloads), and on at least seven occasions the feed to the mill had to be completely stopped to grind the mill out. Also, the mill load varied in the range of 125 to 165 tons. These disturbances propagated throughout sections, such as secondary and tertiary crushing, ball mill grinding and classification. The results showed that a combination of semi-autogenous and ball mill grinding is an appropriate way of comminution circuit optimization.

The process of realizing iron ore beneficiation optimization

The process of realizing iron ore beneficiation optimization

The paper demonstrates the application of this methodology to optimize solids concentration in ball milling of an iron ore from Brazil. The wet grinding experiments were conducted in bench (0.25 m diameter) and pilot-scale mills (0.42 m diameter), and surveys in a full-scale industrial (5.2 m diameter) mill. Important advances have been made in the last 60 years or so in the modeling of ball mills using mathematical formulas and models. One approach that has gained popularity is the population balance model, in particular, when coupled to the specific breakage rate function. The paper demonstrates the application of this methodology to optimize solids concentration in ball milling of an iron ore ...
