| High shear mixer for liquids |
The high shear liquid and paste mill, also known as a high pressure homogenizer or high shear homogenizer, is equipment used to reduce the size of particles in liquids and to create emulsions and fine dispersions. Let’s explore what a high shear mill is for and how it works:
What is it for:
Particle Size Reduction: The high shear mill is designed to reduce the size of solid particles in liquids, resulting in a fine, homogeneous mixture.
Emulsion Creation: It is used to emulsify and disperse immiscible components such as oil and water, creating stable emulsions.
Production of Suspensions: Used to produce fine and homogeneous suspensions of particles in liquids.
Deagglomeration: Can be used to deagglomerate particles, providing a more uniform mixture.
Solubility Improvement: Helps improve the solubility of certain components in liquids.
How it works:
Processing Chamber:
The equipment consists of a processing chamber where the shearing action takes place.
High pressure bomb:
A high-pressure pump system forces the liquid or slurry through a narrow opening (homogenization valve) at high speed.
High Shear:
The liquid is forced through the homogenization valve at a very high velocity, creating intense shear forces.
Diffusion and Shear:
The fluid passes through very small diffusers or holes in the valve, resulting in intense turbulence and shear.
Particle Disintegration:
Solid particles or agglomerates are disintegrated and reduced in size due to shear and impact forces.
Homogenization and Emulsification:
The high shear process homogenizes the mixture, creates stable emulsions and evenly disperses the components.
Particle Size Control:
Particle size can be controlled by adjusting pressure, valve geometry and other operating parameters.
Cooling:
Some applications may involve cooling the product during or after the process to prevent thermal damage.
Benefits:
Efficient Size Reduction: Provides efficient and controlled size reduction of solid particles.
Emulsification and Homogenization: Ideal for creating stable emulsions and homogenizing mixtures.
Precise Control: Allows precise control of particle size and distribution of the final product.
Applications in Different Sectors: Widely used in food, pharmaceutical, chemical and cosmetic industries.
The high shear mill is a valuable tool in processes that require particle size reduction and the creation of homogeneous mixtures, especially when dealing with complex liquids and pastes. |
