How do I select the right refractory mixer for a shutdown?

Selection depends on the type of castable, whether it will be poured, vibration-cast, or gunned, and the batch volume needed per pour. Low-cement and ultra-low-cement castables typically need tighter water control and a mixer with variable speed settings. Smaller repairs might only need a compact pan mixer, while a full kiln reline needs higher continuous output to avoid cold joints. Sparkline Group discusses the material spec and installation method before recommending a model. This conversation is worth having as early as possible in shutdown planning.
