1.Impact Crushing: Directly break large materialsWhen the ball mill is running, alumina grinding balls rotate with the inner wall of the mill cylinder to a certain height, then fall or cascade freely under gravity.

The falling grinding balls produce strong impact force on the large materials in the cylinder, directly crushing them into smaller particles.

The performance of alumina grinding balls is determined by their alumina content (purity). Different purity levels correspond to different application scenarios, and their suitability for ultra-fine grinding is also classified accordingly. 

Alumina grinding balls, also known as wear-resistant ceramic balls, ceramic balls, porcelain balls, corundum balls, grinding balls, high-alumina balls, microcrystalline alumina balls, etc., are made from high-quality alumina powder as the raw material, mixed with bauxite and roller bar powder. They undergo processes such as batching, grinding, powder making, forming, drying, and calcination—quite literally going through "eighty-one trials"—and are mainly used as grinding media in the form of grinding balls. They come in various specifications with diameters ranging from 0.5mm to 80mm, offering a wide range of choices.

1. Used as Ceramic MaterialSpherical micro-powder possesses excellent press-forming and sintering properties, which are extremely beneficial for producing high-quality ceramic products.

Our 99.5% High Purity Alumina Grinding Bead is a specialized milling medium engineered exclusively for pigment dispersion—addressing the critical challenges of pigment processing, such as preserving color accuracy (no impurity-induced color distortion), achieving uniform particle size distribution (to ensure consistent tinting strength), and minimizing wear (to avoid contamination of pigment pastes). Crafted from 99.5% high-purity alumina powder via precision manufacturing processes—including ultra-fine raw material screening (particle size ≤0.3μm) to eliminate color-altering impurities, isostatic pressing for homogeneous density (preventing uneven wear), high-temperature sintering (1700℃–1780℃) for full densification, and precision spherical polishing (sphericity ≤0.03mm) for smooth milling action—this bead delivers reliable, high-quality dispersion results for all types of pigments (organic, inorganic, metallic, and carbon-based).
