Regular maintenance includes inspecting and replacing wear liners and paddle tips, checking bearing seals for abrasive dust ingress, calibrating the water dosing system, and cleaning residual refractory buildup after each mix change to avoid cross-contamination between chemistries. Because refractory aggregates are highly abrasive, wear parts on a mixer degrade faster than on a standard construction mixer and should be inspected on a defined schedule rather than only when performance drops. Sparkline Group offers scheduled maintenance visits and genuine wear parts to keep mixers performing to specification throughout a shutdown season. Planning maintenance ahead of a major relining program is the best way to avoid unplanned downtime.
