What’s Ceramic Glaze?
Ceramic glaze is a critical component in ceramic tile and ware manufacturing. It serves as the glassy coating that enhances aesthetic appeal, surface durability, and functionality. Ceramic glaze is composed mainly of raw materials such as quartz, frits, fluxes, kaolin, and other inorganic additives. It requires precise particle size control and uniformity to ensure consistent performance after firing. To achieve this, superfine grinding processes, particularly air pulverizer, have become essential in modern ceramic glaze processing.
Why Superfine Grinding of Ceramic Glaze is Essential?
Superfine grinding is necessary to attain a narrow particle size distribution with fine particles typically below 1 µm to 10 µm, critical to maintain glaze homogeneity and optimize melting behavior during firing. The finer the particle size, the greater the surface area, which enhances glaze reactivity and sintering efficiency. This results in shorter firing times, lower glaze usage, improved surface gloss, and better water resistance in the final fired ceramic product. For example, research demonstrates that with average particle sizes reduced to below 0.3 µm, the amount of glaze used can be decreased to one-third of conventional levels while improving brightness and color after firing.
Why Use Air Pulverizer for Ceramic Glaze Processing?
Air pulverizer is widely preferred for ceramic glaze superfine powdering due to its ability to produce high fineness alongside a narrow particle size range without thermal degradation or contamination. The process uses high-velocity compressed air to induce particle collisions and grinding without mechanical contact. It eliminates contamination risks from grinding media. Additionally, the air pulverizer allows precise classification of particles to maintain uniformity. It’s essential for glaze quality and supports dry milling, reducing the need for drying steps common in wet milling processes.
Key Considerations in Ceramic Glaze Air Pulverizer
Successful air pulverizer of ceramic glaze requires attention to various parameters. These include:
Feed material characteristics such as moisture content, hardness, and initial particle size.
Milling pressure and airflow velocity, which impact grinding efficiency and particle breakage.
Classifier speed settings to control the cut-off size for product fineness and ensure a tight particle size distribution.
Prevention of overheating to maintain glaze chemical and physical stability.
Equipment wear resistance given abrasive nature of ceramic materials.
By optimizing these parameters, air pulverizer can yield consistent superfine powders with a desired particle size range typically between 0.1 µm to 10 µm, crucial for high-quality glazing. patents.
