GSM series mixers can solve problems that ordinary spiral and square tubes cannot solve, that is, under the same proportion, mixing capacity and viscosity, its mixing efficiency is 3 times that of ordinary spiral and square mixers, that is, it can achieve the same mixing effect with 1/3 of the length. Especially in extreme cases, such as foam mixing, viscosity or mixing ratio, its mixing efficiency is 6-10 times that of ordinary spiral and square mixers.
