Read MoreFor smaller plant in the 1980s, these ores were treated through a single-stage SAG mill grinding to 75 or 106 μm. This type of circuit is still straightforward in its design concept. High-competency ores or ores requiring a finer product size frequently require two stages of grinding and a number of design issues become important.• Mill orientation. For smaller plant, the mills can be arranged in parallel if the

It is ground to a particle size of 80% passing 100 μm in a semi-autogenous grinding mill then sent on to leaching using sulfuric acid and sulfur dioxide under atmospheric conditions. A schematic flowsheet of this part of the process is shown in Figure 30.4.

Read More2017-2-20 All Grinding Mill Ball Mill Manufacturers understand the object of the grinding process is a mechanical reduction in size of crushable material. Grinding can be undertaken in many ways. The most common way for high capacity industrial purposes is to use a tumbling charge of grinding media in a rotating cylinder or drum.
Read MoreHigher media mass - In a ball mill, it is typical to compensate for the relatively small point of contact of an individual grinding ball by using tens and often thousands of balls. However, as the number of grinding balls increases, so to must their size and therefore mass decrease, often to fractions of a gram.
