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.

Raymond mill

Guilin Hengda Mining Machinery Co., Ltd is a professional supplier from China. For Alunite raymond mill, HD series is a good choice, it breakthrough the bottleneck of the grinding mill, the production is 20-30% higher than traditional raymond mill, The increase mechanism of linkage pressure of the rollers, which greatly prolongs the useful life of the equipment and increases the capacity by 20% under the same power. With the original roller assembly, the oiling time increased 6 – 15 times, achieve the application of oil once, use for 30-45 days.Higher Accuracy powder Classify, without coarseness missing, e accuracy is 80-600 meshes. The classify efficiency reached 99%. HD series has the advantages of high production, high qualification rate Low noise and vibration in grinding of the 325-400 meshes.

HD series high efficiency raymond mill specifications:

Max feeding size: ≤35mm

Main motor power:45-315KW

Capacity: 1-60t/h

Final product size: 80-400 mesh

Applications : For non-metallic minerals with a Moh’s hardness of 6 or less and moisture content of 6% or less, it has a high productivity and high grinding power, such as talc, calcite, calcium carbonate, dolomite, , Kaolin, clay, graphite, zircon sand, bentonite and other non-metallic minerals.
