PEBBLE MILLS. No steel grinding media is used in a fully autogenous mill. When choosing primary autogenous grinding, run of mine ore up to 200300 mm in size is fed to the mill. When using a crushing step before the grinding, the crusher setting should be 150200 mm. The feed trunnion opening must be large enough to avoid plugging.

Grinding iron ores in conventional ball mills involve a considerably high consumption of metallic media, resulting in high operating costs. In the case of compact itabirites, the high silica content increases such consumption, potentially exceeding the costs associated with electric power consumption in industrial operations. This paper presents research conducted to assess the use of compact ...

The feed samples of X, Y, and Z iron ores were ground in the BBM (ball mill refers to a BBM of size 300 mm × 300 mm with smooth liners) to identify the PSD, BWI, and RT of each ore. Grinding experiments were conducted according to Bond's standard test procedure [].For each iron ore sample, the RT taken to produce 250% circulating load in the BBM was measured by a new method.

Much of the remaining iron ore resources in Brazil consist of lowgrade itabirite ores. Accordingly, a typical beneficiation circuit includes a fourstaged crushing/screening plant, followed by grinding in a closedcircuit ball mill, desliming in hydrocyclones and final ore mineral concentration via multistage reverse flotation and thickening of the final product.
