Coating and Ink Slurry Production Plant
Daswell Powder offers you three types of sand mill equipment for coating and ink slurry production, meeting your needs for micron and nano requirements.
Coating and inks are widely used in industries such as construction, automotive, packaging, printing, electronics, and industrial manufacturing. Its quality mainly depends on pigment particle size, slurry uniformity, color strength, gloss, and storage stability.
To achieve excellent product performance, pigment powders must be processed into fine and uniform slurry. Advanced wet grinding equipment helps you improve particle size distribution and pigment dispersion quality, and produce stable coating and ink slurry.
Daswell Powder Tech. provides professional coating and ink slurry production solutions for you. They are suitable for producing various pigment slurry used in paints, coatings, printing inks, color pastes, and specialty materials.
Coating and Ink Slurry Production Process
Generally speaking, the production of coating and ink slurry involves the following steps:
Raw Material Preparation: You should prepare pigment, fillers, and other solid materials according to the product formulation. You can use a high-speed disperser to wet and pre-disperse the solid particles, forming a uniform slurry.
Wet Grinding: The prepared materials enter the sand mill. Grinding media generate strong impact and shear forces to reduce particle size and break agglomerates.
Adjustment and Blending: After grinding, you can add additional resins, solvents, and additives to adjust viscosity, color, gloss, and other performance properties according to product requirements.
Filtration and Packaging: The finished slurry is filtered to remove impurities and oversized particles. And then they can be transferred to storage tanks or downstream production processes according to customer requirements.
Raw Materials and Applications of Coating and Ink Slurry Production
The production of high-quality coating and ink slurry relies on the proper combination of pigment, resins, solvents, additives, and fillers. The following are the main raw materials commonly used in coating and ink slurry production:
| Raw Material Category | Typical Materials |
| Pigments | Titanium Dioxide (TiO₂), Carbon Black, Phthalocyanine Blue, Iron Oxide Red |
| Resins (Binders) | Acrylic Resin, Polyurethane Resin, Epoxy Resin, Rosin-Modified Phenolic Resin |
| Solvents / Diluents | Deionized Water, Ethyl Acetate, Xylene, UV Monomers |
| Additives | Dispersants, Defoamers, Leveling Agents, Anti-Settling Agents |
| Fillers | Ground Calcium Carbonate (GCC), Barium Sulfate, Talc Powder, Kaolin |

After grinding and dispersion, the slurry becomes an essential intermediate product used in various coating and ink applications.
Three Types of Sand Mills for Slurry Grinding
In coating and ink slurry production, it is key for you to choose the right sand mill. It affects the particle size, dispersion quality, and production efficiency. Daswell Powder offers you three types of sand mills to meet your different application requirements: disc sand mill, pin-type sand mill, and nano sand mills.
The disc sand mill is one of the most widely used wet grinding machines in the coating and ink slurry production solutions. It is suitable for continuous production and offers reliable performance, high throughput, and low operating costs. This machine has simple structure, easy maintenance, and large production capacity.
It is widely used in the production of architectural paints, emulsion paints, anti-corrosion coatings, wood coatings, offset printing inks, as well as various pigment and filler slurries. They are particularly suitable for applications requiring high throughput and economical operation.

For applications, which requires finer particle sizes and high product quality, the pin-type sand mill is an ideal choice. Its high-energy grinding structure delivers stronger impact and shear forces. Then, it reduces particles size efficiently and improves the slurry quality.
These pin-type sand mills are commonly used for industrial coatings, water-based coatings, high-concentration color pastes, carbon black dispersions, flexographic inks, and gravure inks. They are ideal for products that demand improved color strength, gloss, and dispersion quality.
