Corundum Grinding Tank Lab Planetary 99% Al2O3 Alumina Ceramic Ball Mill Jars 

99 al2o3 corundum ball mill jar high purity alumina grinding tank lab planetary ball mill jar wear resistant ceramic milling container laboratory powder grinding jar anti contamination ceramic mill tank industrial ceramic milling vessel

Product Description

This 99% Al2O3 corundum ceramic ball mill jar is a professional anti contamination grinding container specially developed for laboratory planetary ball milling equipment. The 99% high purity corundum ceramic matrix has outstanding physical and chemical stability suitable for high precision powder grinding experiments. Its ultra high structural density effectively reduces wall peeling and particle falling during high speed rotation and impact milling. The pure alumina composition avoids metal ion precipitation and material cross contamination, which fully meets the purity requirements of new material powder, chemical raw material and electronic ceramic powder processing. The material retains stable mechanical performance under long term high frequency vibration and cyclic impact, with low abrasion loss and long service life. The integrated sintered structure has no internal gaps, achieving good pressure resistance and tight sealing compatibility with standard ball mill sealing accessories. It supports dry grinding and wet grinding dual processing modes for diversified laboratory milling demands.

Feature

*High purity 99% corundum alumina material with dense crystal structure improves overall wear resistance far beyond ordinary ceramic tanks
*Ultra low abrasion loss effectively prevents tank body peeling and impurity mixing to ensure high purity of milled powder samples
*Excellent chemical inertness resists erosion from most organic and inorganic solvents suitable for wet and dry dual grinding scenarios
*Integrated high temperature sintered structure enhances impact resistance adapting to long term high speed planetary milling operation
*No metal ion precipitation avoids sample pollution ideal for high precision laboratory material research and development
*Customizable volume caliber and appearance size fully compatible with mainstream laboratory planetary ball mill equipment
