Working principle of refractory castable pan mixer:
1. Rotational mixing: The components of refractory castable (such as aggregate, powder, binder, etc.) are uniformly mixed through the interaction between the rotating disk and the mixing blades of the pan mixer.
2. Efficient mixing: The design of the mixing blades causes the materials to be sheared, flipped and dispersed during the rotation process, thereby achieving a fast and uniform mixing effect.
3. Discharge control: After mixing, the mixed refractory castable is discharged through the discharge port for subsequent construction or molding.
