· The characteristic differences between open and closedcircuit grinding systems were examined via the use of a continuous vibration ball mill and a blade type classifier. For the same median diameter of the product, the rate of powder production in the closedcircuit is about 5% higher than that of the opencircuit.

For fine regrinding in open circuit, the ratio ranges from :1 to :1. Some ball mills are separated in to compartments by grates. The grates hold back particles above a certain size for additional grinding. The compartments could contain different ball sizes. Large to small from the feed end. Some mills have a conical section.

AG/SAG mills can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill, and some or all of the work of a ball mill. Because of the range of mill sizes available, AG/SAG milling can often be accomplished with fewer lines than in a conventional rod mill/ball mill circuit.

Opencircuit voltage (abbreviated as OCV or V OC) is the difference of electrical potential between two terminals of a device when disconnected from any circuit. There is no external load connected. No external electric current flows between the terminals. Alternatively, the opencircuit voltage may be thought of as the voltage that must be applied to a solar cell or a battery to stop the current.
