Gravimetric blending involves several critical steps: 1. Accurate Weighing: Each component of the mixture is weighed with high precision using analytical balances. 2. Mixing: The weighed components are combined in a mixing vessel. This can be done using various mixers, such as ribbon blenders, paddle mixers, or tumbling mixers, depending on the nature of the materials. 3. Quality Control: Samples from the blended mixture are taken and analyzed to ensure homogeneity and accuracy in composition.
