What causes inconsistent mixing or batch quality in a refractory mixer?

Inconsistent batches usually result from incorrect water dosing, insufficient dry-mix time before water is added, or worn paddle blades that no longer distribute material evenly. Residual hardened material left from incomplete cleanout of a previous batch can also contaminate a new mix. Diagnosis should start by checking water calibration and paddle condition before assuming a material quality issue. Sparkline Group provides technical support to identify the cause of batch inconsistency during active shutdown work.
