The Jindex Chunk Valve
Milling circuit flow with particle size up 10 mm including scats, 70% solids and flow velocity of 15 m/s through a pinch valve. Pinch valve sleeves were being replaced every 3 weeks. This was far longer than traditional metal valves, however site needed maintenance to occur during programmed shutdowns every 12 weeks.
Jindex custom designed and built a ceramic chunk valve which could handle the extreme circuit flow. Maintenance now occurs every second planned shutdown: 24 weeks. The increased availability of the plant contributes significantly to plant tonnages and reported revenues.
