What are the wet dispersing and grinding equipment for the coating and paint industry Horizontal sand mill
In the coating and paint industry, wet dispersing and grinding equipment is one of the important equipment in the production process. Its main role is to grind pigments and fillers to micro fine particles, so that they are evenly dispersed in the coating medium, thus improving the covering power, uniformity and gloss of the paint. At present, the wet dispersing and grinding equipments in the coating and paint industry mainly include horizontal sand mill, vertical sand mill, basket sand mill and three-roller machine.
I. Horizontal sand mill
Horizontal sand mill is one of the most commonly used wet dispersing and grinding equipment in the coating industry. It adopts advanced grinding technology, through the sand grinding media in the high-speed rotation of the rotor role, the material for strong impact and grinding, so as to achieve the purpose of refining the material. Horizontal sand mill has the following characteristics:
1. High efficiency: Adopting high-speed rotor and stable sanding media, it can achieve high energy-efficient grinding effect.
2. Continuous operation: continuous feeding and discharging can be realised to improve production efficiency.
3. Easy to clean: the equipment structure is simple, easy to disassemble, easy to clean and maintain.
4. Wide range of applications: suitable for grinding a variety of materials, such as coatings, paints, dyes, etc.
II.Vertical sand mill
Vertical sand mill is a new type of wet dispersing and grinding equipment, its working principle is similar to horizontal sand mill. Vertical sand mill adopts vertical structure, covers an area of small, easy to operate and maintain. Its characteristics are as follows:
1. compact structure: vertical structure, small footprint, can effectively save space.
2. Easy operation: the equipment is easy to operate and maintain, which can reduce the production cost.
3. Wide range of application: it is suitable for grinding many kinds of materials, such as paints, lacquers, dyestuffs and so on.
III. Basket mill
Basket mill is a more special wet dispersion grinding equipment, the grinding principle is through the stirring shaft installed on the stirring paddle and grinding media in the paint for impact and grinding, so as to achieve the purpose of refining the material. The characteristics of basket sand mill are as follows:
1. Suitable for small batch production: Basket mill is suitable for small batch and multi-species production needs, especially suitable for laboratory and pilot production.
2. High-efficiency mixing: the equipment can achieve efficient mixing effect, so that the material is evenly dispersed in the grinding process.
3. Easy to clean: the equipment has a simple structure, easy to disassemble, easy to clean and maintain.
4. Wide range of application: it is suitable for grinding many kinds of materials, such as paints, lacquers, dyes and so on.
IV. Three roller Mill
Three roller mill is an older wet dispersion grinding equipment, its working principle is through the gap between the three rollers on the material for shearing and grinding. The characteristics of three-roller machine are as follows:
1. large shear force: the three-roller machine has a large shear force, which can effectively grind the high viscosity paint.
2. Suitable for high viscosity materials: It is suitable for grinding high viscosity materials, such as thick slurry paint.
3. open operation: the three roller mill is open operation, the material volatility is large, and the manual operation is labour-intensive.
