Agate Bead Description
Agate Beads are crafted from pure, natural imported agate stone through processes including cutting, grinding, and polishing. They come in three shapes: spherical, cylindrical, and square. These balls are characterized by their dense structure, transparent coloration, high elastic modulus, and excellent wear resistance. This product is ideal for pure and efficient dispersion and grinding of various light-colored materials in vertical stirred mills and horizontal rolling ball mills.

FAQs
Q1. What are Agate Beads?
Agate beads are grinding media made from natural agate, a form of chalcedony, which is a variety of quartz. These beads are prized for their hardness, smooth surface, and ability to minimize contamination during milling processes.
Q2. What are the main advantages of using Agate Beads?
High Hardness: Agate beads have a high Mohs hardness, which makes them resistant to wear and effective for grinding and milling.
Low Contamination: Since agate is a natural material, it is less likely to introduce impurities into the milled material, making it ideal for applications where purity is critical.
Smooth Surface: The naturally smooth surface of agate beads helps in achieving uniform grinding with minimal abrasion to the milling vessel.
Q3. In which applications are Agate Beads commonly used?
Agate beads are typically used in:
Laboratory Milling: Particularly for grinding small sample sizes where contamination must be minimized.
Pharmaceuticals: In the milling of drugs and active ingredients to ensure purity and uniformity.
Ceramics and Pigments: For grinding and mixing materials that require precise particle size control without contamination.
Q4. What sizes are available for Agate Beads?
Agate beads are available in a range of sizes, typically from a few millimeters to several centimeters in diameter, depending on the specific milling requirements.
