It is extremely important to clarify the relationship between mulling power requirement and tensile-breakup energy for rational design and evaluation of the industrial mulling processes. In the present study, both transient and steady state mulling power has been measured and tensile process curves have been obtained by using a green mold sand with a bentonite as a binder calcined at various temperatures in a vertical cylindrical mixer. The results obtained are as follows: The tensile-breakup energy, time required to complete the mulling process and mulling power requirement are influenced by the tensile strength of the binder used and its calcined temperature. The mulling power requirement can be evaluated in terms of the tensile-breakup energy. These findings of the tensile process tests can be applied to estimate the power requirement for the mulling process.
