Q:
Do you know of any disastrous mistakes that occurred due to the incorrect usage of industrial mixers?
14 answers
Answers:
Yes, gearbox failure due to mixer designed for mixing products whose viscosity is lower than actual value. Another case where mixing takes many times longer because a condition like foaming was not taken into account, restricting the mixing speed.
~Danial Irfachsyad, Research & Development, Jakarta, Indonesia
