How to Make Better Slaked Lime Paint with Ball Mill
In the field of architectural coatings and new environmentally friendly materials, slaked lime paint is widely used in interior and exterior wall decoration due to its good adhesion, antibacterial and eco-friendly properties. In its production process, the selection and operation efficiency of the ball mill directly affect the fineness and dispersion performance of the final product. This article will explore the performance improvement strategy of slaked lime paint from two aspects: formula optimization and grinding process, aiming to provide feasible practical references for related industries.
Slaked Lime Paint Optimization Strategy
Slaked lime paint is mainly composed of slaked lime slurry, water and natural mineral pigments. With its natural alkalinity and excellent adsorption capacity, it is widely used in traditional and modern green buildings. To improve its performance, we can start from the following aspects:
Slaked lime quality control
The selection of high-purity slaked lime with a calcium hydroxide (Ca(OH)₂) content of ≥95% helps to improve the whiteness, antibacterial properties and carbonization efficiency of the paint. The lime slurry needs to be fully aged, and the recommended aging time is not less than 15 days to enhance its stability and construction adaptability.
Formula adjustment and functional additives
By introducing natural protein additives (such as casein) or modern environmentally friendly synthetic emulsions, the flexibility and adhesion of the coating can be improved. To enhance hiding power and uniformity of particle distribution, mineral fillers such as quartz powder, talcum powder or kaolin can be added in appropriate amounts.
Optimization of coating construction process
The risk of cracking and peeling can be effectively avoided by using a “wet-on-wet” multi-layer construction process. A drying interval of 8-12 hours should be maintained between each layer to help form a uniformly structured calcium carbonate crystal layer, thereby improving the durability and overall performance of the coating.
Application of ball mill optimization in slaked lime production
In the processing of slaked lime and its coatings, the ball mill is the main powder processing equipment, and its operating parameters and structural configuration directly affect the fineness and activity of lime. The following optimization suggestions are based on mature industrial practice standards and are applicable to all types of dry or wet ball milling equipment.
Technical Specifications
Working principle of ball mill
The material is fed into the first chamber of the mill evenly through the feeding device and the hollow shaft spiral. The chamber has a stepped lining or corrugated lining, which contains steel balls of different specifications. The centrifugal force generated by the rotation of the cylinder brings the steel balls to a certain height and then falls, which has a heavy impact and grinding effect on the material. After the material is roughly ground in the first chamber, it enters the second chamber through a single-layer partition plate. The chamber is inlaid with a flat lining plate and contains steel balls to further grind the material. The powder is discharged through the discharging grate plate to complete the grinding operation.
Ball mill manufacturers direct sales, affordable prices
Ball mill prices have always been a big puzzle for users. The market quotation of this equipment is generally not clearly marked, because it involves different manufacturers, different manufacturing methods, different purchasing channels (direct sales manufacturers or dealers), production material selection, and the differences between each type of equipment, etc. These will more or less affect the price of the ball mill. Among them, the price of small ball mills is relatively low. For specific equipment quotations, customers need to consult the manufacturer directly.
