Clogging is not random; it follows predictable physics. Zoom GlobalMech Corp analyzed 300 service calls and identified four primary culprits: (1) excessive slump loss beyond 40 mm between hopper and point of placement, (2) aggregate gap-grading that creates voids filled with bleed water, (3) pipeline bends clustered within 3 m causing momentum loss, and (4) pumping pressure below 40 bar which allows aggregate to settle. Recognizing the signature prevents hours of blind hammering.
