1kg of 20mm white ceramic grinding balls. 20mm diameter alumina (Al2O3) ceramic balls, very hard wearing and ideal for ball milling. For volume calculations, 1kg will take up roughly half a litre. 1kg of 20mm balls is roughly55 balls, but the exact quantity can vary.
CERAMIC LINED BALL MILL. Ball Mills can be supplied with either ceramic or rubber linings for wet or dry grinding, for continuous or batch type operation, in sizes from15″ x 21″ to 8′ x 12′. High density ceramic linings of uniform hardness male possible thinner linings and greater and more effective grinding volume.
