Question

Difference between size reduction and size separation

Answer 1

size reduction to reduce size nd size separation to seprate size

Answer 2

Answer:

Size reduction is the process of reducing substances to smaller particles. Size separation is a process in which particles of desired size are separated from other fractions.

Explanation:

Size Reduction

• Objective: The main objective of size reduction is to produce smaller particles either for their larger surface or because of their shape, size and number. The final product normally consists of a mixture of particles which may contain a wide variety of sizes and shapes.
• Application: Size reduction is used to improve solvent efficiency, in this process it reduces the distance traveled to extract solute from the solid in which it is embedded. Size reduction is carried out in many processing industries to enhance or rather, ensure easy handling of materials.
• Disadvantages: Decomposition of drug can occur due to the excessive heat production during milling. Another reason is increased surface area also contributes in drug decomposition.

Size Separation

• SeparationObjective: Particle size determination is necessary for tablet and capsule production. Mixing powders should be improved. During production, particles should be made more solubilized and stable. During production, agitation, screening, and feed rate should be optimized.
• Application: In the production of tablets and capsules, particle size and size distribution are used to determine particle size. Analyze raw materials such as griseofulvin, aspirin, and even food to evaluate quality. Testing the effectiveness of size reduction processes.
• Disadvantages: Sieving cannot be used to separate mixtures with identical sizes of particles.
