Introduction
The colloidal mill is an indispensable team in the food industry, Pharmaceutical, Cosmetics and chemistry. Its main function is to reduce the size of particles in liquid or pasty suspensions, creating a homogeneous and stable mixture. This article explores in depth what a colloidal mill does, Its structure, Principles of operation, types, advantages, Application fields and much more. If you dedicate yourself to food transformation, MANUFACTURE OF CREAMS OR EMULSIONS, This content will be especially useful.
1. What is a colloidal mill?
A colloidal mill is a machine that is used for ultrafine grinding and the homogenization of liquid or semiquid materials. Its mechanical action reduces particles from a material to colloidal dimensions (between 1 nanometer and 1 micrometer), producing a uniform and stable suspension.
2. Structure of a colloidal mill
A colloidal mill is mainly composed of:
- Electric motor: Provides the necessary energy for the rotation of the discs or stators.
- Rotor and stator: They are discs that rotate at high speed, one fixed and another mobile. Among them is an adjustable separation where the grinding process occurs.
- Cooling system: Many models include cooling systems to avoid product overheating.
- Product feed and output hopper.
3. Principle of operation
The colloidal mill works under the combined principles of:
- Shearing: Generated by high relative speed between the rotor and the stator.
- Friction: As the particles rub each other and against the albums.
- Turbulence and impact: The rotation causes swirls that contribute to the disintegration of particles.
This continuous process allows particle size to be reduced effectively and achieve a uniform mixture.
4. Types of Colloidal Mill
4.1 Molino coloidal vertical
- Compact, Ideal for continuous processes.
- Used in the food industry, cosmetics and chemistry.
4.2 Horizontal colloidal mill
- Greater processing capacity.
- Better for viscous materials.
4.3 Colloidal mill
- Use abrasive stones for more traditional grinding.
- Ideal for products such as peanut butter, Tahini, etc.
