Large steel structures often require pre-heating before welding to ensure the metal bonds correctly without becoming brittle.
Trying to push a 2-cubic-meter mixer to do 2.5 cubic meters puts lateral pressure on the drum walls that they weren't engineered to handle. The Danger Zones: Where to Look
Drill a small hole at both ends of the crack to stop it from spreading further. Mixing Station Crack
The constant opening and closing, combined with the weight of the falling concrete, makes this a prime spot for hairline fractures.
Instead of just a patch, engineers may recommend adding structural gussets to redistribute the weight that caused the crack in the first place. Prevention: The Best Defense The constant opening and closing, combined with the
If you are performing a maintenance walk-through, focus your attention on these high-risk areas:
Mixing stations deal with immense torque and heavy loads. Over years of operation, constant vibration weakens the molecular structure of the steel, leading to "stress cracks." Over years of operation, constant vibration weakens the
A mixing station is the heart of a batching plant. It consists of a large mixer (often a twin-shaft or planetary model), support frames, scales, and silos. A usually refers to a fracture in the metal casing of the mixer drum, the structural support beams, or the welding joints that hold the high-vibration components together.
