The starting selection criteria are basic as we are adjusting the mill base at this stage: Average shear rate Coatings system: waterborne, or solvent-based; Of course, you may have extra criteria to meet all your requirements. For example, you may try to limit VOCs.

10%This quantity is small compared to the power used by a semi-autogenous mill and a ball mill in a primary grinding circuit; a ball mill can have an installed power of up to 15 MW, while installed power for a SAG mill can go up to 25 MW. However, the energy used for fine grinding is still significant.

Lime addition to the mill also provides for good mixing of lime with the incoming ore. 2. Rougher flotation – Lime is added after primary (typically SAG) and secondary (ball) milling, usually in a conditioning tank, to ensure optimal pH control in the subsequent rougher flotation process. 3.

DR is a subset of business continuity planning . DR planning begins with a business impact analysis that defines two key metrics: A recovery time objective (RTO), which is the maximum acceptable length of time that your application can be offline. This value is usually defined as part of a larger service level agreement (SLA).

Conveyor Systems Selection Considerations. When deciding on which conveyor system best suits your needs, a key consideration is the material is being transported. Some important characteristics to consider are size, flowability, abrasiveness, corrosiveness, moisture content, and the temperature at which it must be kept.

Matching Mill Drive Description to Mill Requirements Once the power level for the primary (SAG) mill has been set, i.e., design tonnes per hour (tph) x design E total kWh/t from the "geo-comminution" sample profile, serious thought can be applied to sizing the required grinding equipment. Space here does not permit a detailed discus-

lic system, drive system, lubrication and cooling systems, and the feed chute. Feed is introduced into the gap between the rolls in a choke-feed manner, and is comminuted by a mechanism of interparticle breakage. Feed coarser than the gap is broken by nipping. The de-gree of comminution achieved is determined by the pres-

For fully autogenous grinding the mill drives are usually selected with a rating so that the drive is slightly oversized, to allow for variations in ore specific gravity and charge level. For example, if the ore is quite uniform and normal operation is expected to be 30% charge, a drive is selected at, perhaps, a 35% charge.

When mill diameter and mill power became again increased, only the Gearless Mill Drive (GMD) could be envisaged to cover this requirement above 10 MW. The GMD is by its nature a variable speed drive system. Process operators, once having the facility of adjustable speed, could not live anymore without it for SAG mills.
