V cone or Twin Shell Blender Applicable for solid - solid mixing. Batch type tumbling mixer Available as both with or without blade
- 5. Principle Mechanism: Tumbling action Force: Shearing force if blades are present. Ordered mixing by mechanical means Key for mixing efficiency: blender speed Ref: 1) Subrahmanyam C.V.S. , Setty J.T , Suresh.S, Devi V.K . Mixing. Pharmaceutical Engineering. Unit Operation 2. 2nd Ed. Delhi: Vallabh Prakashan; 2013.p.70-94.
