In batch operation, all ingredients are loaded into the mixer together or in a pre-defined sequence, and mixed until a homogenous material is produced and discharged from the mixer in a single lot. The output of a batch mixer is measured in kg/batch.
The continuous mixer on the other hand is generally dedicated to a single high volume product. Ingredients are continuously charged into the mixer in accordance with the formulation. The mixing takes place as the material travels from the charging port to the discharge nozzle, from where it is continuously discharged. The output of a continuous mixer is measured in kg/hr.
