Finally got my suction line to stop clogging on that silt-heavy stretch of the Missouri
Been working a channel maintenance job near Sioux City for the past three weeks, and the silt was just murder on my 10-inch cutterhead dredge. Every other hour, I was shutting down to clear a partial blockage in the suction line, losing a ton of production time. I was about ready to pull my hair out. On a hunch, I started running the ladder a full foot higher than my usual depth setting for that material, and I bumped the swing speed way down, like to maybe 70% of normal. It felt wrong, like I wasn't being aggressive enough. But you know what? Letting the cutter just kiss the top layer and swing slow gave the pump a steady, manageable slurry instead of a dense slug of pure muck. Went a full 8-hour shift yesterday without a single clog. Has anyone else had to tweak their approach that much for super-fine sediment?
