Ball Mill Rejects Line Isolation
Maximize mill uptime and decrease water usage with isolation solutions that perform in the rigors of rejects processing.
More Productive Ball Mills With Reliable Rejects Handling
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.

Recommended Products
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.
Emerson’s Clarkson KS1 is a TRUE bi-directional, zero – leakage ASME Class 150 knife gate valve, specifically designed to handle the challenges of severe service applications. Engineered to prolong valve longevity and maintenance intervals, the KS1 aims to offer a lower total cost of ownership.
- TRUE bi-directional, zero leakage performance for severe services
- Patented gate edge seal system eliminates leakage through top of valve
- Heavy cross-section, precision-molded elastomer seat increases sealing surface area to maintain zero-leakage performance for more cycles

One of the challenges of commodity producers in general and mining companies in particular is that they have very little control over demand and pricing for their products. 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 …
