Mill waste, or tailings, are abrasive and cause severe wear on piping components as they are collected and delivered to the tailings storage facility (TSF). Tailings applications often see the highest solids content slurry, and highest pipeline volume, and can have a wide range of pressures. Isolation valve performance and life span have a direct impact on mill throughput and operating costs.
The following products are capable of providing zero leakage shutoff through high pressure, high solids content slurry. These valves are engineered for an extended cycle life in abrasive media and rapid, on-site repair to maximize uptime.
Andy Coxall joins podcast host Jim Cahill to discuss the challenges in tailings management, the problems with valves not suited for this severe-service application, and why severe-service knife gate valve technology such as the Clarkson KS1 is the best choice for these challenging slurry applications.

ver másBased on many plant visits and discussions with Emerson customers, I have concluded that handling slurries is one of the biggest problems for operators and reliability teams. The most frequently mentioned issues are clogging and erosion, which certainly take their toll, but there is also a more subtle challenge related to measuring flow. Why slurries …
