What is A Colloid Mill?

A colloid mill is a mechanical apparatus that utilizes the relative movement of rotors and stators to process wet materials. Functioning as a kind of grinding equipment, the colloid mill operates on the principle of shearing and grinding materials between a series of rotors and rotating stators at high speed. When the material passes through the gap between the stator and rotor, it undergoes intense mechanical forces that break down the particles or droplets to the desired size. The processed particles typically range from 50 to 200 meshes, with a homogeneity exceeding 90%, making it an ideal device for fine material processing.

This machine consists of grinding units, base transmission part and electric motor. The core of the colloid mill consists of the shell, stator, and rotor. The main body of the colloid mill is crafted from high-strength stainless steel. And the stator and rotor especially undergo a strengthening process, offering excellent corrosion resistance and wear resistance. In essence, a colloid mill is not just a grinding machine; it’s a precision tool that excels in creating finely dispersed and homogeneous mixtures. Its unique ability to handle materials with higher viscosity and larger particles.

Colloid Mill Working Principle

The colloid mill operates by the relative motion of rotors and stators under the power of electric motor. The rotor rotates at a high speed, while the stator remains stationary. The processed material is processed through shear forces, frictional forces, high-frequency vibrations. This powerful combination of forces efficiently emulsifies, disperses, homogenizes, and pulverizes the material, achieving a finely ground and emulsified product. By the way, the gap between the rotor and stator is adjustable according to various materials to control the size of the particles or droplets produced. A smaller gap results in finer particles or droplets.

1. Rotor and Stator

Rotor is a rotating disc, and the stator is a stationary component. The rotor is equipped with blades, teeth, or cutting surfaces. The high-speed rotation of the rotor generates centrifugal forces. When the material passes through the gap between the stator and rotor, it is effectively broken, dispersed, and emulsified. Tianzhong Machinery also offers various options of grinding teeth, made of different materials, including martensitic stainless steel (vacuum quenching or QPQ process), alloy spraying, and diamond spraying.

2. Adjustable Gap

The adjustable gap between the rotor and stator allows to control the size of the particles produced by the mill. Change the gap by turning the adjusting handle, and the adjusting ring drives the axial displacement of the stator.

3. Drive System

The drive system provides the necessary power to rotate the rotor at high speeds. It typically includes an electric motor that drives the rotor.

Types of Colloid Mill Machines

1. Vertical Colloid Mill

The vertical colloid mill is driven by an electric motor, which, through belt transmission, rotates the rotor at high speed. The vertical structure occupies a small area, allowing for long operating times, reduces eccentricity of the shaft, and facilitates easy replacement. Moreover, it can be operated by personnel with basic training.

2. Horizontal Colloid Mill

The horizontal colloid mill is powered by an electric motor, driving the rotor at high speed. But the horizontal structure is prone to eccentricity issues, requires professional personnel to replace the internal structure and damaged grinding heads and shafts.

Structurally, the vertical type uses belt transmission, allowing for a speed increase of 3-5 times compared to the motor alone, resulting in better grinding efficiency compared to the horizontal colloid mill. However, the motor and the grinding part of the horizontal colloid mill are separated. The motor is safer if the material moisture splashes out.

How to Choose Colloid Grinder?

Choosing the right colloid mill machine involves considering several factors to ensure optimal performance and efficiency. Here are key factors to consider:

1. Material Flowability
– High Flowability: If the material has good flowability, you can opt for a smaller model.
– Poor Flowability: For materials with poor flowability, a larger model with increased power is necessary to prevent strain on the motor and ensure a longer lifespan.

2. Particle Size of Material
If the material has large particles, it is advisable to choose a colloid mill with a larger inlet size. Or please pre-process the material to reduce particle size before feeding it into the colloid mill. Tianzhong Machinery also offers crushers to choose from.

3. Capacity Requirements
Consider the required production volume and choose a colloid grinder with a corresponding capacity. Selecting a machine with the right output ensures efficiency and prevents overloading. Besides, if the material is difficult to grind, choose a machine with wear-resistant stator and rator to enhance durability and reduce maintenance needs.

FAQs About Colloidal Mill

1. Q: Is it necessary to roast or soak nuts before grinding? And why?

A: Yes. If you want nut butter or paste, you need to roast the nuts first; if you want nut milk, you need to soak the nuts first. It is because that our colloid mill is a wet grinding equipment, which is used to grind fluid raw materials. When roasting nuts, the oil of nuts can be fully released, and then get perfect nut butter. While it can increase the moisture of nuts, then it helps to get the best nut milk if soaking nuts first.

2. Q: Is colloid mill the same as the homogenizer?

A: The short answer is no. In essence, colloidal mills and homogenizers serve similar purposes in terms of particle size reduction and emulsion formation. But they are distinct pieces of equipment with some differences.


In conclusion, the colloid mill machine from Tianzhong Machinery stands out as a precision tool in achieving finely dispersed and homogeneous mixtures.
