Also, the mill load varied in the range of 125 to 165 tons. These disturbances propagated throughout the milling circuit and even to the flotation circuit. The Millstar Power Optimiser gave the following benefits: • Mill feed cuts were prevented, resulting in a stable mill loading. • No huge power dips occurred, since any sign of the mill
HYDRAULIC CIRCUIT DESIGN AND ANALYSIS A Hydraulic circuit is a group of components such as pumps, actuators, and control valves so arranged that they will perform a useful task. When analyzing or designing a hydraulic circuit, the following three important considerations must be taken into account: 1. Safety of operation 2.

Closed, open, and short circuits. Electrical current is represented by the yellow arrows. In the open circuit, no current flows at all. In the closed circuit, current flows through the lightbulb, causing it to light up. In the short circuit, current flows directly between the battery terminals, bypassing the lightbulb, so it does not light up.
A problem for solving mass balances in mineral processing plants is the calculation of circulating load in closed circuits. A family of possible methods to the resolution of this calculation is the iterative methods, consisting of a finite loop where each iteration the initial solution is refined in order to move closer to the exact solution.
