Creating/modifying a mill

Entering/changing a mill

Mills are added to projects, and then circuits are created out of combinations of mills. See the section on Creating a project to create a project to add a new mill to.

For the purposes of the model, a crusher is considered a special type of mill. Adding a crusher is the same as adding a mill. Primary gyratory (or jaw) crushers are not part of the modelling because all Power Models start with a feed F₈₀ size that is assumed to be primary crusher discharge.

Entering a new mill

From the circuit flowsheet page, click the [Add new mill to circuit] link at the bottom of the flowsheet. This will bring up a dialogue containing a series of pre-configured mills or a "blank" template. Click the mill you want to add.

The editing page for that mill will appear. Continue with the instructions to change a mill.

Changing an existing mill

The list of attributes that can be modified on the mill editing page is different for each mill power draw model.

If you change the model type, some of the data needed will be different and certain data fields will disappear from the dialogue, and other data fields may appear. Some items may be blank if a particular attribute of the new model did not exist in the old model.

Adding a mill to the default list

The list of default mills (those that appear in the "Add new mill to circuit" menu) is determined by your Administrator.
