Colloid mill

Colloid mill can be divided into stainless steel colloid mill and half-formed stainless steel colloid mill. The basic principles is when fluid and semi-fluid material go through the fixed gear and moved gear which is high-speed relatively linked, can be influenced by strong shear, friction and high-frequency vibration, and be effectively crushed, emulsified, homogenized. So that precision products can be made.

Classification of Colloid Mill

1. According to Structure: there are Vertical Colloid Mill and Split Colloid Mill

2. According to Angle of Appearance: there are Ordinary Colloid Mill and Sanitary Colloid Mill

Structure of Colloid Mill

The main structures of colloid mill are grinding parts, the base transmission department and dedicated motor. The dynamic and still millstones in the core part and mechanical seal parts are the most key parts. Therefore, according to the different natures of the materials, the selection must be different. But the materials are made of stainless steel or specific materials. The motor need to be designed specifically, depend different model. The motor flange should install retaining plate to prevent leakage.

Usage of Colloid Mill

1. Food Industry: dairy products, chocolate, soy sauce, jam, peanut butter, butter and beverage

2. Chemical Industry: paints, lubricating oil, spices, dyes, emulsified asphalt, emulsified rubber, catalyst, paint coating etc.

3. Pharmaceutical Industry: cod liver oil, athlete cream, bee honey, pollen etc.

4. Daily Chemical Industry: shoe polish, toothpaste, cosmetics, balsam, soap, and detergent, etc

5. Other Industry: building industry, paper industry, plastic industry, battery industry, etc

Characteristics of Colloid Mill

Relative to the pressure-type homogenizer, colloid mill first is a kind of centrifugal equipment. It has the advantages of simple structure, convenient maintenance and is suitable for high viscosity materials and large particles materials. Also, its main drawback is determined by its structures. First, as for the centrifugal movement, the flow is not constant, corresponding to viscous material, the flow vary greatly. For example, the same equipment, in dealing with viscous lacquer and thin dairy fluid, the flow speed can differ 10 times above. Second, because of the high-speed friction between the stator and material, it is easy to generate large quantity of heat, and make the material processed. Third, the surface is easy to wear, and after wearing, the refined results will be significantly reduced.
