After grinding in the ball mill, fragments of ore remain that are too large to pass through the screen to the next phase. These fragments, along with foreign matter that can include broken balls from the mill, are ushered to the rejects line. Valves isolating these lines must provide zero leakage shutoff to prevent valuable water loss, while also being robust enough to resist severe impact damage.
The following products are capable of providing zero leakage shutoff of ball mill reject lines. They are also engineered to resist heavy impact damage and extend the uptime of your mill.
A white paper, High-Performance Control Valves for Water Addition Processes in Ore Mining, highlights the importance of valve selection in reducing operational and maintenance costs, waste, and water usage.

Individual producers benefit or suffer through up and down cycles, and find they really only have control over their own internal variables. These days, specialty metals and …
