Internal batch mixing machines with non-intermeshing rotors of increasedperformance

Abstract From the Canadian patent

Non-intermeshing four wing and three-wing rotors for use in high intensity mixing machines of the batch type provide new sequences and new characteristics of dynamic interactions for achieving advantageously increased mixing effectiveness and strength of the rotors. These new rotors are adapted for driving at unequal speed (unsynchronized rotation) or at equal speed (synchronized rotation). In the four-wing rotors long wings and short wings both, originate from both ends of the rotor. The new four-wing and three-wing rotors intensify axial and transverse distributive mixing for causing the mixes (batches) to become more homogeneous. The markedly increased twist angles T in both types of …
