Alunite is generally blocky or earthy. Its crystal is not obvious and it is a cryptocrystalline mineral. If the purity should be white, but contains impurities after the light gray, light red, light yellow or reddish-brown, glass luster, bottom cleavage moderate.
Alunite can be used in manufacturing, chemical industry, food industry, agriculture, chemical industry, and environmental sanitation industries. It is used in printing, paper making, tanning, painting, and other industries. It is also used as a mordant for dyeing cloths, as well as for ramming and filming. Hardeners, catalysts for ammonia synthesis, clarifiers for sugar and water, precipitants for beneficiation etc.
Guilin Hengda Mining Machinery Co., Ltd is a professional ultrafine mill manufacturer from China. For Alunite ultrafine mill, HGM series is a good choice, not only for its factory price, but also multiple layers of multiple grinding roller, grinding wheel bracket with a combination of structure, the drive spindle is s multi-angle diamond-shaped structure, crushing power strong, less maintenance, easy demolition, low cost, and the finished product does not turn back.
HGM multi-layer curved roller mill is the ideal equipment for the current dry production of non-metallic mineral powder. Main Unit equipped with built-grading institutions, grading wheel unique structure, grading effect, powder particles concentrated, no large particles of pollution. Grinding ring with a special wear-resistant alloy steel or high chromium manufacturing, life increased by 2-3 times. Main unit base with the overall cast steel structure, high structural strength, shock absorption performance.
