Size Reduction Processes Quiz

It is the processes used to separate and classify particles based on their size. These processes are commonly used in various industries such as agriculture, food processing, pharmaceuticals, and mining. The primary goal is to separate particles into different size fractions or to remove oversized or undersized particles from a material.

• Fluid Energy Milling

• Sifting and Screening

• Cryogenic Size Reduction

• Ball Mill

It involves subjecting materials to repeated collisions and frictional forces within a controlled environment. These processes are used to achieve particle size reduction and are common in impact mills and agitated media mills.

• Screening and Sieving

• Homogenization

• Agglomeration and Compaction

• Impact and Attrition

It is the process of applying mechanical forces to materials to break them into smaller particles. It involves compression, impact, and shear forces. Crushers, such as jaw crushers, cone crushers, and impact crushers, are commonly used for primary and secondary crushing.

• Crushing

• Grinding

• Milling

• Cutting and Shearing

This process involves reducing the size of materials by cooling them to very low temperatures. The brittleness of materials increases at low temperatures, making them more susceptible to size reduction.

• Attrition Milling

• Ultrasonic Milling

• Comminution

• Cryogenic Size Reduction

What is commonly used for general grinding purposes?

• Steel Ball

• Ceramic Ball

• Aluminum Ball

• Rubber Ball

It is often used to create mixtures or emulsions with consistent properties.

• Screening and Sieving

• Fluid Energy Milling

• Pulverization

• Homogenization

What does fluid energy milling uses to reduce particle size through impact and attrition?

• Air pressure

• Mechanical forces

• High-speed gas streams

• Shear forces

It is used to create high-frequency vibrations that break down particles.

• Compression

• Blades

• Ultrasonic waves

• Friction

Cryogenic size reduction can be employed to produce nanostructured materials with specific properties and applications in fields like electronics, energy storage, and catalysis.

• High-Value Materials:

• Metal Powders:

• Nanostructured Materials

• Pharmaceuticals

It is the process of reducing particle size and achieving uniform distribution within a material. It is often used to create mixtures or emulsions with consistent properties.

• Screening and sieving

• Agglomeration and Compaction

• Homogenization
