SAG Mills

• Vp Estimation provides three different methods for determining the mill volumetric load (Vp).

• Power Draw models for predicting SAG mill power draw characteristics.

• Ball Charge Estimation can be used to provide an estimate of the percent steel in the overall charge for your SAG mill based on power draw models.

• Mill Critical Speed can be used to quickly calculate the mill critical speed based on mill rpm and diameter.

• Ball Charge characteristics provides an estimate of the characteristics of the ball charge in your SAG mill which are important in terms of its grinding and wear performance.

• Impact Energy charts provides a graphical illustration of the relationship between impact energy and falling distance for various steel ball diameters.

Ball Mills

• Vp Estimation provides three different methods for determining the mill volumetric load (Vp).

• Mill Power Draw can be used to determine the ball mill power draw characteristics, which are closely tied to the nature of the ball charge present in the mill.

• Mill Critical Speed can be used to quickly calculate the mill critical speed based on mill rpm and diameter.

• Ball Charge Characteristics provides various characteristics of the ball charge in the mill which are important in terms of its grinding and wear performance.

• Ball Sizing can be used to determine the recommended size of grinding ball to be adding to the ball mill.

• Ball Size Distribution generates charts comparing the predicted ball size distribution by weight and by surface area for two different equilibrium ball charges.

Rod Mills

• Vp Estimation provides three different methods for determining the mill volumetric load (Vp).

• Mill Power is used for determination of rod mill power draw characteristics.

• Mill Critical Speed can be used to quickly calculate the mill critical speed based on mill rpm and diameter.

• Rod Sizing makes use of Fred C. Bond’s formula for determining the recommended diameter of rod added to the rod mill.

• Rod Weight is a calculator used to determine the weights of individual and bundled rods.

With the help of DEM simulations performed on the EDEM platform, we are able to project mill charge trajectories, issue Ramp Up proposals, and simulate the number of effective collisions for different particle sizes and collision energies generated at different stages of a campaign.

We use JKSimMet models to carry out diagnostic studies on the grinding process. These are based on surveys and analyses of key operating variables, power models to control ball charge levels, and tools to boost metallurgists’ management capacity (ME Elecmetal – Grinding Apps).

Digital Modules

Dispatch Tracking: Online information on deliveries to the concentrator plant, for better inventory control and quality traceability.

Bin Tracking: Monitoring of the fill level of ball storage bins.

Quality Tracking: Continuous graphic displays showing our customers the quality, chemical, weight, and hardness parameters of the product batches sent to the plant.

Feed Tracking: Accurately controls the number and weight of balls entering the mill and keeps an up-to-date inventory of the balls in the mill for more efficient operational control.

In-Mill Tracking: Simulation of grinding media size distribution inside the mill, as a function of ball size, discharge size (grate slot), daily charges and theoretical wear (ME Grinding Apps).

Scrap Tracking: Periodic monitoring of scrap properties (morphology and quantity). Provides early indications of deviations: product problems or undesired operational issues.
